A graphing calculator finds the regression line to be
y = 5.5x + 52
Answer:
1500
Step-by-step explanation:
STEP 1 900 = 60% × Y
STEP 2 900 =
60
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 60 we will arrive at:
STEP 3 Y = 900 ×
100
60
STEP 4 Y = 900 × 100 ÷ 60
STEP 5 Y = 1500
