Data were collected every five years on the population of the countries in the UN. The following computer output and residual plot for the power model were provided. Based on the residual plot, is the power model appropriate? Yes, the residual plot clearly displays the curve of a power function.

Yes, the residual plot very clearly displays scatter around the residual = 0.
No, the residual plot shows us that a quadratic model is appropriate.

No, the residual plot does not show random scatter around the residual = 0. answer is d

d

Step-by-step explanation:

No, the residual plot does not show random scatter around the residual = 0.

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.
