Olad Company wants to forecast sales for three different products (annual sales in the table, in units):YEARTELEVISION SETSRADIOSCOMPACT DISC PLAYERS1250300110225031010032503201 20425033014052503401706250350150725 03601608250370190925038020010250390 190a) What is sales forecast of television sets in year 11?b) What is sales forecast of Radios in year 11?c) What is sales forecast of Compact Disc Players in year 11?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

good luck!

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
