Answer:
17
Step-by-step explanation:
Given the regression model :
Y=ax+b
x = Hours of TV watched per day
y= number of sit-ups a person can do
A=-1.341
B=32.234
Y = - 1.341x + 32.234
Predict Y, when x = 11
Y = - 1.341(11) + 32.234
Y = −14.751 + 32.234
Y = 17.483
Hence, the person Cann do approximately 17 sit-ups
answer : (0,1) (3,2) (6,3)
Answer:
y = 5
Step-by-step explanation:
This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:
1. Combine like terms:
-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8
2. Isolate the variable using inverse (opposite operations):
Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y
Add -4y to both sides: -4y + 5 + 4y = -3y + 4y
3. Solve for 'y'
5 = y
