Three runners competed in a race. data were collected at each mile mark for each runner. if the runner ran at a constant pace, the data would be linear. a regression line was fitted to their data. use the residual plots to decide which data set is best fit by the regression line and then identify the runner that kept the most consistent pace.

Runner A

Step-by-step explanation:

Just took the test.

the one that looks like it's going strait the runners letter change so whatever one is going the straitest is right

Step-by-step explanation:

ape-x

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
