A regression analysis was performed to determine if there is a relationship between hours of TV watched per day (2) and
number of sit ups a person can do (y).
The results of the regression were:
y=ax+b
a=-0.951
b=20.676
p2=0.480249
r=-0.693
Use this to predict the number of sit ups a person who watches 7.5 hours of TV can do, and please round your answer to a
whole number

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
