In 2006 there was a punter named John who kicked 49 times for 1582 yards. In 2007, he kicked 52 times for 1977 yards. Did he significantly improve? Assume the standard deviations both years for the mean punting distance was 5 yards. Let a = 0.05.

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

it is a horizontal line.

answer: the answer is 84.

step-by-step explanation: i just answered it and 84 is correct. look at the graph and it should be the number between 2 points on the graph.
