Find the least squares regression line modeling this data. What is the slope of the regression line? Round your answer to three decimal places.

depends on how many days you are talking about

step-by-step explanation:

true

step-by-step explanation:

it is more then likely a review to you prepare for an upcomign test or quiz

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

yes i do see that. i say this because i am doing my very best in high school so i can get a scholarship and credits.
