Amelia used a random sample of 100 accounts receivable to estimate the relationship between days (number of days from billing to receipt of payment) and size (size of balance due in dollars). her estimated regression equation was days = 22 + 0.0047 size with a correlation coefficient of .300. from this information we can conclude thata) 30 per cent of the variation in days is explainedby size. b) if the account balance is $1000 it will take onaverage 26.7 days to receive payment. c) the relationship between days and size issignificant. d) larger accounts tend to take less time to pay.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

maximum area = xy = (16)(32) = 512 ft2
