Is there a relationship between total team salary and team performance in a sport such as professional football? To answer this question we will examine the number of wins and total team payroll in a recent season for all the teams in the National Football League (NFL). The data are in this Excel file. Question 1. Let the x-variable be the team payroll and let the y-variable be the team wins. Find the intercept b0 and slope b1 of the least squares prediction line (Wins)^^\^ = b0 + b1*Payroll.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
