Answer:

-36.

Step-by-step explanation:

First term a1 = 21.

Common difference d = 18 - 21 = -3   (15-18 = -3)

nth term an = a1 + (n - 1)d

So 20th term = 21 + (20-1) -3

= 21 - 3 * 19

= 21 - 57

= -36.

The 20th term of the arithmetic sequence will be -36.

The nth teem of an arithmetic sequence is calculated by using the formula: a + (n - 1) d.

The 20th term will be:

= a + (n - 1) d.

= a + (20 - 1)d

= a + 19d

where,

a = first term = 21

d = common difference = 2nd term - 1st term = 18 - 21 = -3

Therefore, 20th term will be:

= a + 19d

= 21 + 19(-3)

= 21 - 57

= -36

Therefore, the 20th term is -36

Answer:

The probability of making at least one of these errors is 0.0025

Step-by-step explanation:

Consider the provided information.

Let P represents the error in processing.

Let F represents the error in filling.

Let R represents the error in retrieving.

The probability of an error in processing is 0.0010: P(P) = 0.0010

The probability of an in filing is 0.0009: P(F) = 0.0009

The probability of an error in retrieving is 0.0012: P(R) = 0.0012,

The probability of an error in processing as well as filing is 0.0002:

P(P∩F) = 0.0002

The probability of an error in processing as well as retrieving is 0.0003,

P(P∩R) = 0.0003

The probability of an error in processing and filing as well as retrieving is 0.0001.

P(P∩F∩R)=0.0001

P(R∩F)=0.0002

The probability of at least one is:

P(P∪F∪R)=P(P)+P(R)+P(F)-P(P∩F)-P(P∩R)-P(R∩F)+P(P∩F∩R)

P(P∪F∪R)=0.0010+0.0009+0.0012-0.0002-0.0002-0.0003+0.0001

P(P∪F∪R)=0.0025

To graph a system of linear equations, start at the y-intercept and use the slope to plot the next points. The solution to the system of equations is the point where the lines intersect, and can be found by setting the equations equal to each other and solving.

The problem involves graphing a system of linear equations, which are y = x + 5 and y = 2x + 2.

Each equation is in the form of y = mx + b, where m is the slope and b is the y-intercept. For the first equation, the slope is 1 and the y-intercept is 5. For the second equation, the slope is 2 and the y-intercept is 2.

To graph these, you typically start at the y-intercept (where the line crosses the y-axis) and use the slope to determine the next points on the graph - you rise/run according to the slope.

The solution to the system of equations is the point where the two lines intersect. To find this point, you need to solve the system of equations either graphically or algebraically. This would involve setting the equations equal to each other and solving for x, and then substituting that value of x into either of the original equations to solve for y.

Answer:

Q(x) = [tex](x+3)^{2}+5[/tex] is the final equation.

Step-by-step explanation:

By translation of the graph 3 units upward direction, it means that the y-value of the function is increased by 3 unit at each value of x.

Given , P(x) = [tex](x+3)^{2}+2[/tex]

We can actually translate the graph in any direction, and for that we have to make the necessary changes. If we translate the graph in the positive x direction, then we have to substitute (x - 3) instead of x in the equation.

Since we are translating the graph upwards ,

Q(x) = [tex](x+3)^{2}+2[/tex] + 3

Q(x) = [tex](x+3)^{2}+5[/tex]

This is the final equation of the graph after translation.

Answer: Sum of root a+b = -c/d

Product of root ab= e/d

Step-by-step explanation:

Let the general quadratic equation be dx² + cx + e = 0

And the root of the equation be

'a' and 'b'

Using the general formula to find the solution to the quadratic equation

a = -c+√c²- 4de/2d

b = -c-√c²- 4de/2d

Taking the sum of the roots

a+b = (-c+√c²- 4de/2d) + (-c-√c²- 4de/2d)

a+b = (-c-c+√c²- 4de/2d - √c²- 4de/2d)/2d

a+b = -2c/2d

a+b = -c/d

The sum of the root of the quadratic equation will be -c/d

Product of roots

ab = (-c+√c²- 4de/2d)(-c-√c²- 4de/2d)

= {c² +(c√c²- 4de)- (c√c²- 4de) -(c²-4de)}/4d²

= {c²-c²+4de}/4d²

= 4de/4d²

= e/d

The product of the above quadratic equation will be e/d

Step-by-step explanation:

The psychology class has 9 freshman male, 15 freshman females, 8 sophomore male and 12 sophomore female.

Total population constitution of the class=

17 males and 27 females and 44 students in total.

If on selecting on the first attempt, a male has been picked up then the number of males for the picking up in the second attempt has to decrease by one.

Also, the total number of students from which it has to be selected also decreases by 1, because one child has already been selected.

Therefore for Second Attempt, Total 43 students and 16 males.

Probability=[tex]\frac{No.OfFavorableOutcomes}{TotalNo.OfOutcomes}[/tex]

Probability=[tex]\frac{16}{43}[/tex]

Final answer:

The probability that the second student will also be a male, given that the first student is a male, is 16/43.

Explanation:

To find the probability that the second student will also be a male, given that the first student is a male, we need to determine the number of males left in the sample space after choosing the first male student. In the class, there are 9 freshman males and 8 sophomore males, making a total of 17 males. However, since we are choosing 2 students, the total sample space decreases by 1 after choosing the first male student.

Therefore, the probability of choosing a male as the second student, given that the first student is a male, is:
P(second student is male | first student is male) = (number of males left in sample space after choosing first male) / (total sample space after choosing first male)

P(second student is male | first student is male) = 16/43

Answer:

The 99% confidence interval is given by (8.4;12.6)  

A. (8.4,12.6)

Step-by-step explanation:

1) Notation and definitions  

n=100 represent the sample size  

[tex]\bar X= 10.5[/tex] represent the sample mean  

[tex]\sigma=8[/tex] represent the population standard deviation  assumed

m represent the margin of error  

Confidence =99% or 0.99

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

2) Calculate the critical value zc  

On this case we can to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by [tex]\alpha=1-0.99=0.01[/tex] and [tex]\alpha/2 =0.005[/tex]. The degrees of freedom are given by:  

We can find the critical values in excel using the following formulas:  

"=NORM.INV(0.005,0,1)" for [tex]z_{\alpha/2}=-2.58[/tex]  

"=NORM.INV(1-0.005,0,1)" for [tex]z_{1-\alpha/2}=2.58[/tex]  

The critical value [tex]zc=\pm 2.74[/tex]  

3) Calculate the margin of error (m)  

The margin of error for the sample mean is given by this formula:  

[tex]m=z_c \frac{\sigma}{\sqrt{n}}[/tex]  

[tex]m=2.58 \frac{8}{\sqrt{100}}=2.064[/tex]  

4) Calculate the confidence interval  

The interval for the mean is given by this formula:  

[tex]\bar X \pm z_{c} \frac{\sigma}{\sqrt{n}}[/tex]  

And calculating the limits we got:  

[tex]10.5 - 2.58 \frac{8}{\sqrt{100}}=8.4[/tex]  

[tex]10.5 + 2.58 \frac{8}{\sqrt{100}}=12.6[/tex]

Step-by-step explanation:

The number of peanuts is 40, the number of almonds is 40 and the number of raisins is 20.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Kevin and Mark took a random sample of 100 pieces of trail mix to determine the number of peanuts, raisins, and almonds in a container. If each container of trail mix is known to have 40% peanuts, 40% almonds, and 20% raisins.

The number will be calculated as,

40% peanut = 100 x 40 / 100 = 40

40% almonds =  100 x 40 / 100 = 40

20 % raisins = 100 x 20 /100 = 20

Therefore, the number of peanuts is 40, the number of almonds is 40 and the number of raisins is 20.

Answer:

0.140625

Step-by-step explanation:

Total numbers of possible combinations for a coin = 2^n

If the coin is tossed 10 times, we have 2^10 = 1024

If the coin is tossed once, we have 2^1 = 2 outcomes.

The possible outcomes are H, T.

We have 2 outcomes with no two consecutive head.

If the coin is tossed twice, we have 2^2 = 4 outcomes.

The possible outcomes are HH, HT, TH, TT

We have 1 outcome with two consecutive heads and 3 outcomes without two consecutive heads.

If the coin is tossed thrice, we have 2^3 = 8 outcomes.

The possible outcomes are HHH, HHT, HTH, HTT, TTH, THT, THH and TTT

We have 3 outcomes with two consecutive head and 5 outcomes without two consecutive heads.

Comparing the results from the outcomes of the coin,we have 2,3,5,......

This looks like a financial sequence. For the next 10 tosses, we have

2,3,5,8,13,21,34,55,89,144

We have 144 outcomes without two consecutive heads if the coin is tossed 10 times

Pr(number of two consecutive Heads in 10 tosses) = 144/1024

= 0.140625

The probability that two heads do not occur consecutively in 10 coin tosses is 45/512 or approximately 0.0879.

In order to calculate the probability that two heads do not occur consecutively in 10 coin tosses, we can use the concept of permutations with restrictions. Let's consider the possibilities:

When choosing a head, there are 10 possibilities for the first head (H) and 9 possibilities for the second head.

This gives us a total of 10 * 9 = 90 possibilities.

When choosing tails (T), there are 2 possibilities for each toss, giving us a total of 2^10 = 1024 possibilities.

Therefore, the probability that two heads do not occur consecutively is 90/1024, which simplifies to 45/512 or approximately 0.0879.

#SPJ12

Final answer:

The number 31 is a prime number because it is only divisible by 1 and itself, hence it has one factor pair, which is (1, 31). The correct answer to the question is B - 31 is a prime because it has 1 factor pair.

Explanation:

The question is asking whether the number 31 is a prime number or a composite number and to identify the number of factor pairs it has. A prime number is a number that has only two factors, 1 and the number itself. In contrast, a composite number is a number that has more than two factors.

For the number 31, we can confirm that it is not divisible by any integers other than 1 and 31 without a remainder. Therefore, 31 is a prime number, and it has only one factor pair, which is (1, 31). There are no other pairs of numbers that multiply together to give the product of 31. Thus, the correct choice is B - 31 is a prime because it has 1 factor pair.

The statement is true; as sample size increases, even small differences between two population proportions can lead to the rejection of the null hypothesis. The decreasing standard error with larger samples increases the test statistic, leading to smaller p-values. However, practical significance should also be considered alongside statistical significance.

The statement regarding the hypothesis test for two population proportions is true. As the sample size increases, even a very small difference between the two population proportions becomes significant. This is because with larger sample sizes, the standard error of the difference between the two proportions decreases, which increases the test statistic used in hypothesis testing. As a result, we are more likely to reject the null hypothesis of equal population proportions if the sample size is sufficiently large, assuming there is indeed a small actual difference.

The null hypothesis typically states that there is no effect or no difference, and in the case of two population proportions, it states that the proportions are equal. When we conduct a hypothesis test, we calculate the probability of observing our sample data, or something more extreme, given that the null hypothesis is true. This probability is known as the p-value. A small p-value indicates that the observed data is unlikely under the null hypothesis, leading to its rejection.

However, it's important to note that the ability to detect small differences with large samples does not imply that those differences are practically significant, only statistically so. Therefore, in addition to hypothesis testing, it's essential to consider effect size and practical significance when interpreting results.

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line is

9x+7y=4

7y = - 9x + 4

y = -9x/7 + 4/7

Comparing with the slope intercept form, slope = - 9/7

If the line passing through the given point is perpendicular to the given line, it means its slope is the negative reciprocal of the slope of the given line.

Therefore, the slope of the line passing through (7,-4) is 7/9

To determine the intercept, we would substitute m = 7/9, x = 7 and y = -4 into y = mx + c. It becomes

- 4 = 7/9×7 + c = 49/9 + c

c = - 4 - 49/9 = -85/9

The equation becomes

y = 7x/9 - 85/9

Answer:

Step-by-step explanation:

any eq. of line perpendicular to 9x+7y=4 is

7x-9y=a

a=85

reqd. eq. is 7x-9y=85

This is an improper. Perhaps you can fix it, so that I can assist you with it? I apologise.

Answer:

Step-by-step explanation:

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the information given,

y2 = - a

y1 = a

x2 = 0

x1 = 0

Slope = (- a - a)/0-0 = -2a/0 = 0

2) equation of the line is represented in the slope intercept form as y = mx + c

Where

m = slope

c = intercept.

To determine c, we would substitute y = a, x = p and m = 0 into y= mx + c. It becomes

a = 0×p + c

c = a

The equation becomes

y = a

3) y intercept,c = a

4) the slope of a line perpendicular to the given line is a negative reciprocal of the slope of the given line. Therefore,

Slope = - 0 = 0

Final answer:

The relationship between the force applied to the lever and the distance from the pivot point can be modeled using an inverse variation function. The function that models this relationship is f = 1800/d.

Explanation:

The relationship between the force applied to the lever and the distance from the pivot point can be modeled using an inverse variation function. In this case, the force required to move the rock varies inversely with the distance. Let's denote the force as f and the distance as d. The inverse variation function is given by f = k/d, where k is a constant.

To find the value of k, we can use the given information. When a force of 50 pounds is applied 36 inches from the pivot point, the rock is moved. Plugging these values into the inverse variation equation, we have 50 = k/36. Solving for k, we get k = 50 x 36 = 1800.

Therefore, the function that models the relationship between the force applied to the lever (f) and the distance of the applied force from the pivot point (d) is f = 1800/d.

The function that models the relationship between the force (f) applied and the distance (d) from the pivot point is:

[tex]f(d) = \frac{1800}{d}[/tex]

To model the relationship between the force (f) applied to the lever and the distance (d) from the pivot point, we need to understand that the force varies inversely with the distance. This means that as the distance increases, the force required decreases, and vice versa.

The mathematical model for such a relationship is given by the equation:

[tex]f = \frac{k}{d}[/tex]

Here, k is a constant that we need to determine using the given information. We know that a force of 50 pounds is applied to the lever 36 inches from the pivot point. Plug these values into the equation to find the value of k:

[tex]50 = \frac{k}{36}[/tex]

To solve for k, multiply both sides by 36:

[tex]k = 50 \times 36[/tex]

[tex]k = 1800[/tex]

Now, we substitute the value of k back into the equation to get the final model:

[tex]f = \frac{1800}{d}[/tex]

Answer:

n = 61 costumers

Step-by-step explanation:

For calculating the number of costumers he should sample we use the next equation:

[tex]n = \frac{z_{1-\alpha/2}^{2}p(1-p)}{E^{2} }[/tex]

                          Where E is the error that we are prepared to accept, in this  case E = 0.15

How we don't know the value of p, we can estimate it like p = 0.5

∝ = 1-0.98 = 0.02

1-∝/2 = 0.99

[tex]z_{0.99} = 2.33[/tex]

[tex]n = \frac{(2.33^{2})(0.5)(1-0.5)}{0.15^{2} }[/tex]

n = 60.32 costumers

n ≈ 61 costumers

Final answer:

To determine the sample size needed for the proportion of customers who dislike the new policy on cashing checks, we can use the formula: n = (Z^2 * p' * (1-p')) / E^2. The manager wants a sample fraction within 0.15 of the true fraction with a probability of 0.98.

Explanation:

To determine the sample size needed for the proportion of customers who dislike the new policy on cashing checks, we can use the formula:

n = (Z^2 * p' * (1-p')) / E^2

Where:

n is the sample size

Z is the z-score corresponding to the desired confidence level

p' is the estimated proportion

E is the maximum error or margin of error

In this case, the manager wants a sample fraction within 0.15 of the true fraction with a probability of 0.98. Assuming p' is 0.5, we can calculate the required sample size.

The matrix equation ...

  AX = B

is solved by left-multiplying by the inverse of A:

  A⁻¹AX = A⁻¹B

  IX = A⁻¹B . . . . . the result of multiplying A⁻¹A is the identity matrix

  X = A⁻¹B . . . . . B needs to be multiplied by the inverse matrix

Step-by-step explanation:

We will separate our trips as "slow" and "fast".  Filling in a motion table:

              d        =        r        x        t

slow

fast

We know that the slow rate is 40 mph and the time is, in hours (because the time has to match the rate.  We can't say "40 mph" and then state the time in minutes), 1 hour.

We know that the fast rate is 70 mph and the time in hours is .5 hours.

If distance = rate times time, then the distance traveled at the slow speed is 40 * 1 = 40 miles

The distance traveled at the fast speed is 70 * .5 = 35 miles.

The trip was 40 + 35 = 75 miles total, and the time it took was 1 + .5 = 1.5 hours.

Answer:L(t) = 40 - 2t

Step-by-step explanation:

Total amount of money that Logan borrowed from his friend to buy the video game system is $40

Let x represent the constant amount that he agreed to pay the friend back each week.

After 7 weeks, he still owed his friend $26. This means that the amount that he paid in 7 weeks is 7×x = $7x

He still owed his friend $26.

This means that amount paid in 7 weeks would be 40 - 26 = $14

Therefore

7x = 14

x = 14/7 = 2

He pays $2 each week.

Let t represent the number of weeks, the equation for the function L(t),representing the amount Logan owes his friend after t weeks would be

L(t) = 40 - 2t

Answer:

Step-by-step explanation:

The formula we need here is

[tex]6(6+x)=5(5+x+3)[/tex]

which simplifies to

[tex]6(6+x)=5(8+x)[/tex]

which simplifies to

36 + 6x = 40 + 5x and

x = 4

So DG = 5 + 4 + 3 which is 12
