Answer:

The slope is equal to $\frac{2}{3}$ . So the right answer is A.

Step-by-step explanation:

We know that if we are given to points of a function we can find out its slope by using the following formula....

$m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Where m is the slope, $x_{1}$ and $y_{1}$ are the coordinates of the first point, $x_{2}$ and $y_{2}$ are coordinates of the second point.

Let (-4, 2) be $(x_{1} , y_{1})$

Let (-16, - 6) be $(x_{2}, y_{2} )$

then......

Explanation:

2(5 + 3r)

= (2)(5 + 3r)

= (2)(5) + (2)(3r)

= 10 + 6r

= 6r + 10

*College readiness * i’m lost on how you are supposed it set it up

Murrr4er [49]

The mean grade on the quiz was 88.

<u>Step-by-step explanation:</u>

We need to find the mean grade of the quiz using the information given.

The mean also known as the average is defined as the sum of data entries in a set divided by the number of entries in the data set.

The standard deviation gives the amount of variation or dispersion of data values present in a data set.

The given data are,

The standard deviation of the quiz, SD = 3.
The score 94 is exactly 2 standard deviations above the mean.

The above sentence represents that 94 is above the mean with 2 standard deviations.

⇒ 94 = Mean + 2 standard deviations.

We know the value for standard deviation. So substitute SD= 3 in the expression provided.

⇒ 94 = Mean + (2×3)

⇒ 94 = Mean + 6

To find mean, subtract 6 on both sides.

⇒ 94 -6 = Mean

⇒ Mean = 88

Therefore, the mean grade on the quiz was 88.

find the missing value so the line passing through the points has the given slope.(10,y) and (3,4);m=3/4

Hoochie [10]

Answer:

The value of y is 9¼.

Explanation:

Given that the slope of the set of points (10,y) and (3,4) is 3/4.

Using the slope formula:

$\text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}$

We have:

$\frac{3}{4}=\frac{4-y}{3-10}$

We then solve for y:

$\begin{gathered} \frac{3}{4}=\frac{4-y}{-7} \\ \text{Cross multiply:} \\ 4(4-y)=-21 \\ 16-4y=-21 \\ -4y=-21-16 \\ -4y=-37 \\ y=\frac{-37}{-4} \\ y=9\frac{1}{4} \end{gathered}$

The value of y is 9¼.
