Question

The equation of the linear regression line represents the relationship between the

number of candles sold for charity, x, and the amount earned for charity, y.
ŷ = 10x +41
How much money can the charity expect to earn if 47 candles sold?

Answer 1

511

Explanation:

The equation of the linear regression line represents the relationship between

From the above question, let's represent:

Number of candles sold for charity = x

The amount earned for charity = y .

Our equation is given as:

ŷ = 10x +41

Hence, x = 47

y = 10 × 47 + 41

y = 470 + 41

y = 511

The amount of money the charity should expect is 511
