Answer:
y = - 0.181x + 24157.2
Step-by-step explanation:
Equation of the regression line is given from. The table by the Coefficient of the predictor, x variable and the intercept value :
The predictor here is mileage, which has a Coefficient of - 0.181
The constant value = intercept 24157.2
The regression equation is written in the form :
y = mx + c ; m = slope = Coefficient of predictor, ; x = predictor,
Hence, we have :
y = - 0.181x + 24157.2

set a proportion;
60 3
---- = ---
x 2
3÷60 = 0.05 2
2 ÷ 0.05 = 40
x = 40
hope this helps!
6) √72= √3*25= √3*2*12= √3*3*2*2*2 =3*2√2 =6√2
(just break down the numbers until they are prime numbers. )
