Which type of correlation would you expect to see between the number of items purchased and the amount of money saved? a. positive correlation b. negative correlation c. no correlation

I would expect B. negative correlation between the # of items bought and amount of money saved. When you buy items, you spend money, therefore you save less money the more items you buy.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
