The regression equation for predicting number of speeding tickets (Y) from information about driver age (X) is Y = -.065(X) + 5.
ivolga24 [154]

Answer:

c. 4.27

Step-by-step explanation:

We have been given the regression equation of for predicting number of speeding tickets (Y) from information about driver age (X) as Y=-0.065(X)+5.57.

To find the predicted number of tickets for a twenty-year-old, we will substitute X=20 in our given equation.

Y=-0.065(20)+5.57

Y=-1.3+5.57

Y=4.27

Therefore, the predicted number of tickets for a twenty-year-old would be 4.27 tickets.

Find each angle measure.<br>​
Vitek1552 [10]

Answer for 11-13: m<2: 150, m<6: 150, m<7: 150

Step-by-step explanation:

There is 180 degrees in a straight line. If one part of the line (angle) is 30 degrees, then the other part is 150. If you look at the image, you would see that m<2 is congruent to m<6 ,which means same, and m<7 is congruent to m<3.

Answer for 14-16:  m<EBG: 150, m<AGH: 150, m<DHF: 30.

Step-by-step explanation:

4x = 150               2x + 50 = 150

x = 37.5                2x = 150 - 50

4(37.5) = 150        2x = 100

                             x = 50

                          2(50) + 50 =

                            100 + 50 = 150

aniked [119]

Answer:

E. the product of seven and the difference of b minus two

Step-by-step explanation:

7(b-2)

seven is being multiplied by the difference of b minus 2

So this can be written as the product of seven and the difference of b minus two.

Reasons its not the other answer choices

A. two subtracted from the quotient of seven divided by b would be (7/b) - 2

B. seven added to difference of b minus two would be 7 + (b-2)

C. the quotient of seven divided by b minus two would be 7/(b-2)

D. two subtracted from seven times b would be 7b - 2

Key Vocabulary:

<em>Difference = Subtraction</em>

<em>Product = Multiplication</em>

<em>Quotient = Division </em>
