8(v-4) + 7v = -2                    Original Problem.
8v - 32 + 7v = -2                  Distribute.
8v + 7v = 30                         Add 32 to each side.
15v = 30                               Add.
v = 2                                     Divide each side by 15.

Answer: v = 2

8(v−4)+7v=−2

(8)(v)+(8)(−4)+7v=−2

8v+−32+7v=−2

(8v+7v)+(−32)=−2

15v+−32=−2

15v−32=−2

Add 32 to both sides.

15v−32+32=−2+32

15v=30

Divide both sides by 15.

15v/15=30/15

v = 2

In the app you are creating, a duck is going to fly from the coordinates (1, 3) then go 3 units right. And 6 units down. Write a
nevsk [136]

Answer:

The rule of the translation is  (x,y) ----> (x+3,y-6)

The coordinates of the duck’s final position are (4,-3)

Step-by-step explanation:

we know that

A duck is going to fly from the coordinates (1, 3) then go 3 units right. And 6 units down

That means -----> The rule of the translation is

3 units right ----> x+3

6 units down ---> y-6

so

(x,y) ----> (x+3,y-6)

To find out the the coordinates of the duck’s final position, apply the rule of the translation to the duck’s original position

so

(1,3) ------> (1+3,3-6)

(1,3) ------> (4,-3)

In one study, it was found that the correlation coefficient between two variables is -0.98. Which statement is true?
Vadim26 [7]

<u>Answer- </u>D. There is a strong negative association between the variables

<u>Solution-</u>

Properties of Correlation Coefficient

1-  Its value ranges between -1 and 1.

2- The greater the absolute value of correlation coefficient, the stronger is the linear relationship.

3- The weakest linear relationship is indicated by a correlation coefficient equal to 0.

4- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

5- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

As the given correlation coefficient is -0.98 (-ve), whose absolute value is 0.98 (closer to 1)

So there is a strong negative association between the variables.
