Apsychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test. the scores are from 0 to 100, with higher scores meaning more stress. she finds that there is a negative linear association between w and t that is best modeled by the equation t=−2.5w+48.1 .

what is the meaning of 48.1 in this equation?

a: the people in the study walked an average of 48.1 minutes each day.

b: for each additional minute spent walking, the model predicts that a person's score on the stress test will go down by about 48.1 points.

c: the people who walked each day had an average score of 48.1 on the stress test.

d: the model predicts that a person who does not walk each day will score about 48.1 on the test.

D: The model predicts that a person who does not walk each day will score about 48.1 on the test.

Step-by-step explanation:

Given: A psychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test.

She finds that there is a negative linear association between w and t that is best modeled by the equation .

When we put w=0 minutes, t=48.1

It implies that if any patient doesn't walk will score 48.1.

Hence, the model predicts that a person who does not walk each day will score about 48.1 on the test.

idk this answer sorry cant on this one.

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
