Answer: 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.
X+4=3x-8, x =6, here u go
You'll want to make a common denominator with 6 and 8.
That denominator would be 24.
24/6=4 so you would have to multiply 5/6 by 4/4 to get 20/24.
Next, 24/8=3 so 1/8 could be multiplied by 3/3 to get 3/24.
Since 3 is less than 20, 1/8 is smaller than 5/6.
If you want the same numerator, 5/8 = 15/24. This would make 5/8 smaller than 5/6 as well.
The highest eighth you can go is 6/8 which is 18/24.
So you can use any numerator between 1 and 6 with a denominator of 8 to get a fraction smaller than 5/6.
Answer:y= (3/4)x -7/4
Step-by-step explanation:
[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]
[y + 1]/[x - 1] = 3/4
y + 1 = (3/4)x - 3/4
y = (3/4)x - 7/4.
25% of 40 is 10 so it would be $40+10 for the price so that should be 50. Markup=profit/cost*100
