A member of the school track team is considering purchasing a new set of track shoes, called spikes. However, because they are very expensive, she wants convincing evidence that they will give her a greater ABILITY to run faster than her current spikes before she buys them. So, she decides to conduct an experiment and is able to borrow a pair of the new spikes from a friend on the team to compare to her current spikes. She will use each pair of spikes 10 times and compare her median time in the 400 meters using each pair

78.59 is the mean

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.

roots are from trees

step-by-step explanation:

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
