On a jogging trail, you take a random sample of the speed of 50 joggers and determine that their average speed is 5.3 mph. Which statement is true?

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

because they could drop even lower..

i found two solutions,   n = 2 • ± √3 = ± 3.4641
