2. Can early homework grades predict student’ final score? Answer the questions below using the regression results (unit: point). (3 pts). Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept 51.53 13.45 3.83 0.00 24.26 78.80 HW score 0.36 0.13 2.71 0.01 0.09 0.62 a) Find the equation for the regression line for predicting final score from early homework score. (1 pt) b) Is "homework score" a significant predictor of student’s final score? Why or why not? Provide statistic evidence. (1 pt) c) Interpret slope and y-intercept. (1 pt)

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

middle maybe?

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
