Use the table. Which inference can you make by comparing the measures of center?

A: every runner ran faster last year as compared to this year

B: most runners ran faster last year, on average, as compared to this year

C: the runners ran faster this year, on average, as compared to last year

D: every runner ran faster this year as compared to last year

C: the runners ran faster this year, on average, as compared to last year

Step-by-step explanation:

Mean is a measure of center and MAD is a measure of dispersion. Comparing the means, this year, on average, the runners ran faster than last year.

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
