Final answer:

Kim spent 40/100 of a dollar (40 cents) on a snack, so she has 60 cents left.

Explanation:

The question requires converting a fraction of a dollar into a money amount. Kim spent 40/100 of a dollar on a snack. A dollar is equivalent to 100 cents, so Kim spent 40 cents on her snack. To find out how much she has left, we subtract her spending from the total amount of one dollar.

To perform the calculation: 100 cents - 40 cents = 60 cents.

Therefore, Kim has 60 cents left after purchasing the snack.

Answer:800 miles

Step-by-step explanation:

Given

Round trip for Penthaven to Jackson takes 6 hr and 24 minutes in absence of wind

[tex]t_1=6+\frac{24}{60}=6.4\ hr[/tex]

When Wind blows from Penthaven to Jackson it takes 6 hr and 40 min i.e.

[tex]t_2=6+\frac{40}{60}=\frac{20}{3}\ hr[/tex]

Speed of wind [tex]v=50\ mph[/tex]

Suppose x be the distance between Penthaven and Jackson and u be the speed of plane

So initially

[tex]6.4=\frac{x}{u}+\frac{x}{u}[/tex]

[tex]6.4=\frac{2x}{u}[/tex]

[tex]x=3.2u \quad \ldots(i)[/tex]

When wind is blowing then,

[tex]\Rightarrow \frac{20}{3}=\frac{x}{u+v}+\frac{x}{u-v}[/tex]

[tex]\Rightarrow \frac{20}{3}=x[\frac{1}{u+50}+\frac{1}{u-50}][/tex]

[tex]\Rightarrow \frac{20}{3}=x[\frac{2u}{u^2-50^2}]\quad \ldots(ii)[/tex]

Substitute the value of x in [tex](ii)[/tex]

[tex]\Rightarrow \frac{20}{3}=\frac{2u[3.2u]}{u^2-50^2}[/tex]

[tex]\Rightarrow 10[u^2-50^2]=9.6u^2[/tex]

[tex]\Rightarrow 0.4u^2=50^2\times 10[/tex]

[tex]\Rightarrow u^2=\frac{50^2\times 10^2}{4}[/tex]

[tex]\Rightarrow u=250\ mph[/tex]

Thus [tex]x=3.2\times 250=800\ miles[/tex]

Answer:

3.22% probability that the sample average is greater than $228,500

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

[tex]\mu = 227000, \sigma = 8500, n = 110, s = \frac{8500}{\sqrt{110}} = 810.44[/tex]

What is the probability that the sample average is greater than $228,500?

This is 1 subtracted by the pvalue of Z when X = 228500. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{228500 - 227000}{810.44}[/tex]

[tex]Z = 1.85[/tex]

[tex]Z = 1.85[/tex] has a pvalue of 0.9678

1 - 0.9678 = 0.0322

3.22% probability that the sample average is greater than $228,500

Answer:

This is a circle with centre (6,-7)  and radius 4.

Step-by-step explanation:

The equation of a circle has the following format:

[tex](x - x_{0})^{2} + (y - y_{0})^{2} = r^{2}[/tex]

In which r is the radius(half the diameter) and the centre is the point [tex](x_{0}, y_{0})[/tex]

In this question:

[tex](x-6)^{2} + (y+7)^{2} = 16[/tex]

So

[tex]x_{0} = 6, y_{0} = -7[/tex]

[tex]r^{2} = 16[/tex]

[tex]r = \pm \sqrt{16}[/tex]

The radius is the positive value.

[tex]r = 4[/tex]

So this is a circle with centre (6,-7)  and radius 4.

Answer:

Given equation

(x-6)^2+(y+7)^2=16

centre (6,-7)  and radius 4.

Step-by-step explanation:

The equation of a circle is (x - a)² + (y - b)² = r²

the radius is r

the centre is (a, b)

Given equation

(x-6)^2+(y+7)^2=16

so ,

a = 6

b = - 7

r² = 16

[tex]r = \pm \sqrt{16}[/tex]

r = 4

Therefore,  the circle with centre (6,-7)  and radius 4.

Answer:

b = 7.9

Step-by-step explanation:

A = 37       a =

B = 53       b =

C = 90       c = 10

B = 180 - 90 -37 = 53

[tex]\frac{sinB}{b} = \frac{sinC}{c}\\ \frac{sin(53)}{b} = \frac{sin(90)}{10}\\ b = \frac{10 sin(53)}{sin(90)} \\b = 7.9[/tex]

To find the length of side AC in a right-angled triangle ABC with angle A of 37 degrees and hypotenuse 10, we use the cosine function. AC equals the hypotenuse multiplied by the cosine of angle A, resulting in AC being approximately 7.9 units long.

The student wants to know the length of side AC in a right-angled triangle ABC, where angle C is a right angle, angle A is 37 degrees, and the hypotenuse (side BC) is 10. To find the length of side AC, we will use trigonometric functions. Specifically, we will use the cosine function, which relates the adjacent side to the hypotenuse in a right-angled triangle. The cosine of angle A (cos 37°) is equal to the adjacent side (AC) divided by the hypotenuse (BC).

The formula is: Cosine of angle A = AC / BC

This can be rewritten as: AC = BC * Cosine of angle A

By substituting the given values (BC = 10 and angle A = 37°), we get:

AC = 10 * cos(37°)

To find cos(37°), we can use a calculator set to degree mode. The calculation gives us:

AC = 10 * 0.7986 (approximately)

Therefore, AC ≈ 10 * 0.7986 = 7.986

AC is approximately 7.9 units long.

Answer:

  a) 6 angelfish, 2 clownfish

  b) 4 angelfish, 8 clownfish

Step-by-step explanation:

There are at least a couple of different algorithms for finding integer solutions to problems like this. However, it is easiest to describe a trial-and-error solution.

Here, we have defined a function that tells us the number of clownfish we will get if we purchase some number of angelfish. When the function value is an integer, we have found a solution. We compute the value of the function for all reasonable numbers of angelfish.

a) The problem statement tells us the total purchase amount for "c" clownfish and "a" angelfish will be ...

   3.60c +5.80a = 42.00

We are told that we must buy at least 1 of each kind of fish, so the most clownfish we can buy will be ...

  3.60c +5.80×1 = 42.00

  c = (42.00 -5.80)/3.60 = 10 1/18

And the most angelfish we can buy will be ...

  3.60×1 +5.80a = 42.00

  a = (42.00 -3.60)/5.80 = 6 18/29

Since we can buy fewer angelfish, a trial-and-error solution will look a the number of clownfish we can buy for each different purchase of angelfish.

We can write a function, similar to the equation for "c" above, that tells us the number of clownfish for x angelfish:

  f(x) = (42 -5.80x)/3.60

We want to find the value of x that results in an integer number of clownfish. The attached table shows us that purchase of 6 angelfish will allow purchase of 2 clownfish for $42.

__

b) Using the same idea, we can repeat the process for a total purchase of $52. The attached table tells us the solution is a purchase of 4 angelfish and 8 clownfish for $52.

u + 3v = <-7, 6> + 3 <-4, 17> = <-7, 6> + <-12, 51> = <-19, 57>

We want to find a vector w such that

u + 3v + w = <1, 0>

Subtract u + 3v from both sides to get

w = <1, 0> - (u + 3v) = <1, 0> - <-19, 57>

w = <20, -57>

To get the required vector, subtract u + 3v from the unit vector <1, 0>. The required vector is <20, -57>.

To find the vector that can be added to u + 3v to get the unit vector <1, 0>, we need to subtract u + 3v from the unit vector. This will give us the required vector. Let's calculate:

Unit vector: <1, 0>

u + 3v: <-7, 6> + 3<-4, 17> = <-7, 6> + <-12, 51> = <-19, 57>

And we are 9% confidence that the true mean for the difference of the population means is given by:

[tex] 0.0743 \leq \mu_1 -\mu_2 \leq 1.926[/tex]

Step-by-step explanation:

For this problem we have the following data given:

[tex]\bar X_1 = 9[/tex] represent the sample mean for one of the departments

[tex]\bar X_2 = 8[/tex] represent the sample mean for the other department

[tex]n_1 = 25[/tex] represent the sample size for the first group

Confidence interval

The confidence interval for the difference in the true means is given by:

[tex] (\bar X_1 -\bar X_2) \pm t_{\alpha/2} \sqrt{\frac{s^2_1}{n_1}+\frac{s^2_2}{n_2}}[/tex]

[tex] df=n_1 +n_2 -2= 20+25-2= 43[/tex]

And the critical value for this case is [tex] t_{\alpha/2}=2.02[/tex]

And replacing we got:

[tex] (9-8) -2.02 \sqrt{\frac{2^2}{25} +\frac{1^2}{20}}= 0.0743[/tex]

[tex] (9-8) +2.02 \sqrt{\frac{2^2}{25} +\frac{1^2}{20}}= 1.926[/tex]

And we are 9% confidence that the true mean for the difference of the population means is given by:

[tex] 0.0743 \leq \mu_1 -\mu_2 \leq 1.926[/tex]

We have been given a right triangle. We are asked to find the value of x.

We can see that x is opposite side to angle that measures 62 degrees and adjacent side to angle is 4 units.

We know that tangent relates adjacent and opposite side of right triangle.

The value of y when x = 9 such that the y varies directly with respect to x is 24 therefore, option (D) will be correct.

Proportion is the relation of a variable with another. It could be direct or inverse.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given question,

y varies directly as x

y ∝ x

Removing proportion y = kx

Given that,y=8 when x=3

So, k = 8/3

Therefore, relation converts as, y = (8/3)x

At x = 9 → y = (8/3)9 = 24

Hence "The value of y when x = 9 such that the y varies directly with respect to x is 24".

Answer:

Stratified sampling

Step-by-step explanation:

Members of the population are divided into two or more subgroups called strata, that share similar characteristics like age, gender, or ethnicity. A random sample from each stratum is then drawn. For instance, if we divide the population of college students into strata based on the number of years in school, then our strata would be freshmen, sophomores, juniors, and seniors. We would then select our sample by choosing a random sample of freshmen, a random sample of sophomores, and so on.

This technique is used when it is necessary to ensure that particular subsets of a population are represented in the sample. Since a random sample cannot guarantee that sophomores would be chosen, we would used a stratified sample if it were important that sophomores be included in our sample. Furthermore, my using stratified sampling you can preserve certain characteristics of the population. For example, if freshmen make up 40% of our population, then we can choose 40% of our sample from the freshmen stratum. Stratified sampling is one of the best ways to enforce "representativeness" on a sample.

Step-by-step explanation:

The tangent function has been shifted upward by 2 units, but there has been no horizontal scaling. Any horizontal offset must be equal to some number of whole periods.

Choices A and B show tan( )+2, the correct vertical offset. However, choice A has a horizontal scale factor of 2. The correct choice is B, which has no horizontal scaling (the coefficient of x is 1) and a horizontal offset of π, one full period.

_____

Comment on horizontal scaling

Horizontal scaling is different from vertical scaling in that using k·x in place of x compresses the graph horizontally by a factor of k. On the other hand, using k·f(x) in place of f(x) expands the graph vertically by a factor of k.

Beth's number, which indicates 60 parts out of 100, can be expressed as 60%, 0.60, 60/100, or in simplest form, 3/5. These representations are commonly used in mathematics to show percentages and their equivalent values.

Beth writes a number that shows 60 parts out of 100. In mathematics, expressing a part out of 100 is essentially describing a percentage. So, Beth's number could be expressed in several ways that all represent 60 out of 100. The simplest form would be 60%, which directly translates to 60 per 100. Another possible representation could be 0.60, which is the decimal form equivalent to 60%. If we were to convert this percentage into a fraction, it would be
60/100, which can also be simplified to
3/5. It cannot be a number such as N(60, 5.477) which suggests a normal distribution with a mean of 60 and a standard deviation of 5.477, nor can it be .9990 which is not equivalent to 60 parts out of 100 in any common mathematical representation.

Answer:

Due to the higher z-score, Stewart caught the longer fish, relative to fish of the same species

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Who caught the longer fish, relative to fish of the same species?

Whosoever fish's had the higher z-score.

Stewart caught a bluefish that was 283mm

The mean length of a bluefish is 264 millimeters with a standard deviation of 57mm.

So we have to find Z when [tex]X = 283, \mu = 264, \sigma = 57[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{283 - 264}{57}[/tex]

[tex]Z = 0.33[/tex]

Gina caught a pompano that was 152mm long.

For pompano, the mean is 157mm with a standard deviation of 28mm.

So we have to find Z when [tex]X = 152, \mu = 157, \sigma = 28[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{152 - 157}{28}[/tex]

[tex]Z = -0.18[/tex]

Due to the higher z-score, Stewart caught the longer fish, relative to fish of the same species

The correct answer is Stewart caught the longer fish relative to fish of the same species.

To determine who caught the longer fish relative to the average length of their respective species, we need to calculate the z-scores for both Stewart's bluefish and Gina's pompano. The z-score is a measure of how many standard deviations an observation is above or below the mean.

For Stewart's bluefish:

The mean length of a bluefish is 264 mm, and the standard deviation is 57 mm. Stewart's bluefish is 283 mm long. To find the z-score for Stewart's bluefish, we use the formula:

[tex]\[ z = \frac{X - \mu}{\sigma} \][/tex]

where X is the observed value, [tex]\( \mu \)[/tex] is the mean, and [tex]\( \sigma \)[/tex] is the standard deviation. Plugging in the values for Stewart's bluefish:

[tex]\[ z_{Stewart} = \frac{283 - 264}{57} \] \[ z_{Stewart} = \frac{19}{57} \] \[ z_{Stewart} \approx 0.333 \][/tex]

For Gina's pompano:

The mean length of a pompano is 157 mm, and the standard deviation is 28 mm. Gina's pompano is 152 mm long. To find the z-score for Gina's pompano:

[tex]\[ z = \frac{X - \mu}{\sigma} \] \[ z_{Gina} = \frac{152 - 157}{28} \] \[ z_{Gina} = \frac{-5}{28} \] \[ z_{Gina} \approx -0.179 \][/tex]

Comparing the z-scores:

Stewart's z-score is approximately 0.333, which means his bluefish is 0.333 standard deviations longer than the average bluefish. Gina's z-score is approximately -0.179, which means her pompano is 0.179 standard deviations shorter than the average pompano.

Since Stewart's z-score is positive and larger in magnitude than Gina's negative z-score, Stewart's bluefish is longer relative to its species than Gina's pompano is relative to its species. Therefore, Stewart caught the longer fish relative to fish of the same species.
