Question

A graph has average temperature (degrees Fahrenheit) on the x-axis, from 0 to 60, and total coat sales on the y-axis, from 0 to 100. A trend line goes through points (55, 50) and (65, 40). The regression equation is y = negative 0.96 x + 103.

Use the regression for Clothes-4-You coat sales to make predictions.

How many coats should Clothes-4-You expect to sell when the average temperature is 80°F?

What is the predicted temperature when 125 coats are sold?

Answer 1

its 3 and 60 on edg

Explanation:

Answer 2

• 26 coats; -23°F temperature

Explanation:

For x = 80, we have:

• y = - 0.96*80 + 103 = 26.2 ≈ 26 coats expected to be sold

Predicted temperature when 125 coats are sold:

• 125 = - 0.96x + 103
• - 0.96x = 22
• x = 22/-0.96
• x = -22.9 ≈ -23°F
