Answer:

(C)7x-3x

Step-by-step explanation:

The given algebraic expression is:

"The difference between seven times a number and three times that number"

Let the number be equal to =x, then according to the statement, we have

seven times a number=7x and three times that number=3x

The difference between seven times a number and three times that number=7x-3x

which is the required algebraic expression.

If a coin is fair then it has two faces , one is heads and the another is tails.

The probability getting any favorable outcomes is given by the formula :-

[tex]\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}[/tex]

So the factor effecting probability is just the number of  favorable outcomes and total outcomes.

If a coin is tossed then the probability of getting heads will be :-

[tex]P(H)=\dfrac{1}{2}=0.5=50\%[/tex]

To get heads always this should be 1 , which can be happen if number of  favorable outcomes is equal to total outcomes.

i.e. Number of heads = Number of total outcomes, this means coin should be biased.

Catching the coin in mid-air can never be a factor for this.

Therefore, the little brother's theory is false.

Answer:

Sample Response: The probability of a coin landing heads up is 1/2, or 50%. That fact will not change if the coin is caught in midair.

Answer:

It is irrational and equal to [tex]5[/tex] multiplied by square root of [tex]2[/tex]

Step-by-step explanation:

we have

[tex]\sqrt{32}+\sqrt{2}[/tex]

Remember that

[tex]32=2^{5}[/tex]

substitute in the expression

[tex]\sqrt{2^{5}}+\sqrt{2}=4\sqrt{2}+\sqrt{2}=5\sqrt{2}[/tex]

therefore

It is irrational and equal to [tex]5[/tex] multiplied by square root of [tex]2[/tex]

The 1st quartile q1 is also called the 25th percentile (the bottom 25% of a data set). In this case, if we choose 100 light bulbs, then the 1st quartile will be the 25 bulbs with shortest useful life.

To solve this problem, we would have to use the z statistic. Using the standard distribution tables for z, we locate for the value of z at P = 0.25:

z = - 0.674

Then to calculate for the 1st quartile, we use the formula:

Q1 = x + z * s

where x is the mean, and s is the standard deviation, therefore:

Q1 = 392 + (- 0.674) (9)

Q1 = 385.934

To find the first quartile of a normal distribution, use the z-score corresponding to an area of 25%. For these lightbulbs with a mean of 392 hours and standard deviation of 9 hours, the first quartile is approximately 386 hours.

In statistics, the quartiles of a dataset divide the data into four equal parts. The first quartile, Q1, is the value below which 25% of the data fall. To determine Q1 for the lifetime of a certain type of lightbulb, we use the properties of the normal distribution.

First, realize that 25% of data falls below Q1, and hence using the z-table, we find that z=-0.675 corresponds to an area of 0.25. We then use the formula for a z-score in a normal distribution, z = (X - μ)/σ. Solving for X we find X = z*σ + μ.

Plugging in the known values we get Q1 = -0.675*9 + 392 = 386.025 hours. So, for these lightbulbs, 25% will have failed by around 386 hours.

Answer:

Option 3th is correct

x = 0.5

Step-by-step explanation:

The given functions are:

Function 1: [tex]y = 4^x[/tex]

Function 2: [tex]y=7x^2+4x-2[/tex]

The values of function at x = -0.5, 0, 0.5 and 2 are as follow:

x values     Function 1              Function 2

-0.53                 0.5                            -2.25

0                        1                              -2

0.53                   2.086                      2.0863

2                        16                             34    

From the above table. It is clear that the quadratic function [tex]y=7x^2+4x-2[/tex]  exceeds the exponential function [tex]y = 4^x[/tex] at x = 0.53

Therefore, the approximate x-value in which the quadratic function exceeds the exponential function at x = 0.5

Step-by-step explanation:

The feasible vertices of the system representing Josh's exam are (0,0), (12,5), and (15,1.25). The non-feasible vertices are (15,0), (0,5), and (20,0). Therefore, the ordered pair (15,0) is not a vertex of the feasible region.

1. System of Inequalities:

  - Time constraint: [tex]\(2m + 8s \leq 40\)[/tex]

  - Number of multiple-choice questions: [tex]\(m \leq 15\)[/tex]

  - Number of short-answer questions: [tex]\(s \leq 5\)[/tex]

2. Feasible Vertices:

  - (0,0), (12,5), (15,1.25)

3. Non-feasible Vertices:

  - (15,0), (0,5), (20,0)

So, the ordered pair (15,0) is not a vertex of the feasible region.

Answer: a) y = 90-15x

b) y = 90

c) x = 6

Step-by-step explanation:

Since we have given that

Amount borrowed from his grandmother = $90

Amount he pay back each week = $15

Let the number of weeks be 'x'.

Let total amount owed be 'y'.

So, it becomes

[tex]y=90-15x[/tex]

a) write an equation in standard for that represents the amount owed y after x weeks.

Our equation is [tex]y=90-15x[/tex]

b. find the y intercept of the graph. what does this represent?

For this , we put x = 0.

[tex]y=90-15(0)\\\\y=90[/tex]

So, the y-intercept of the graph is 90.

It represents that the graph intersect y-axis at (0,90)

c. find the x intercept of the graph. what does this represent?

For this, we put y = 0.

[tex]0=90-15x\\\\90=15x\\\\x=\dfrac{90}{15}\\\\x=6[/tex]

So, the x intercept of the graph is 6.

It represents that the graph intersect the x-axis at (6,0)

Answer:

Step-by-step explanation:

Answer:

Sequence 1 is arithmetic and Sequence 2 is geometric.

there are 4 kings and 4 queens in a deck

 chance of getting a king is 1/52

 chance of getting a queen without the king being put back would be 1/51

1/52 x 1/51 = 1/2652 probability

The probability of drawing first a king and then a queen from a standard deck without replacement is 0.603%, which is calculated by multiplying the individual probabilities of drawing a king and then a queen (1/13 * 4/51).

The student is asking about how to calculate the probability of drawing two specific cards from a deck of cards in succession without replacement. In a standard deck of 52 cards, the probability of drawing a king first is 4/52 since there are four kings in the deck. After drawing a king, there are 51 cards left, and the probability of drawing a queen next is 4/51 because there are four queens in the deck. These events are dependent because the outcome of the second draw depends on the first.

To find the combined probability of both events happening, we multiply the probabilities of each event:

P(first card is a king) = 4/52

P(second card is a queen after drawing a king) = 4/51

So, the probability is (4/52) * (4/51), which simplifies to 1/13 * 4/51.

Combined probability = (1/13) * (4/51) = 4/663 = 0.006033182503770739, or about 0.603% when expressed as a percentage.

Answer:

The coefficients are 8 and 1.

Step-by-step explanation:

In order to determine the answer, we have to know about algebraic expressions.

An algebraic expression is conformed by terms or only one term.

A term is just a variable with a coefficient. Also similar terms have the same variable but no always the same coefficient. Therefore if the algebraic expression has two terms, so there are two coefficients. The coefficient with value "1" is not necessary write it.

In this case, we have two terms:

So, we have two coefficients:

Finally, the coefficients are 8 and 1.

Answer:  The required co-ordinates of the point S are (-11, -6).

Step-by-step explanation:  We are given to find the co-ordinates of the point S that lies along the directed line segment from R(-14, -1) to T(4, -13) and partitions the segment in the ratio of 1:5.

We know that

the co-ordinates of a point that divides the line segment joining the points (a, b) and (c, d) in the ratio m : n is given by

[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).[/tex]

According to the given information, we have

(a, b) = (-14, -1),  (c, d) = (4, -13)  and  m : n = 1 : 5.

Therefore, the co-ordinates of the point S are given by

[tex]\left(\dfrac{1\times4+5\times(-14)}{1+5},\dfrac{1\times(-13)+5\times(-1)}{}\right)\\\\\\=\left(\dfrac{4-70}{6},\dfrac{-13-5}{6}\right)\\\\\\=\left(\dfrac{-66}{6},\dfrac{-18}{6}\right)\\\\=(-11,-3)[/tex]

Thus, the required co-ordinates of the point S are (-11, -6).

area = l x w

l = w+3

sqrt(154) = 12.4 round o 12

12-1 = 11

11+3 = 14

11 * 14 = 154

 width = 11

 length = 14
