A customer suspects that one brand of cereal does not fill its boxes with the weight that is printed on the box. He
decides to weigh several boxes to test his theory.
Which of these methods will produce the most representative
sample of the population of boxes containing this brand of cereal?
O A. The customer randomly selects one grocery store, weighs
one case of the cereal, and uses this weight to estimate
the weight per box
O B. The customer randomly selects four grocery stores and
weighs two boxes from each selected store.
C. The customer randomly selects one grocery store and
weighs half the boxes of cereal.
D. The customer randomly selects one grocery store and
weighs all the cereal boxes on one shelf

I think thr answer mughr ve B for what it sais

B.

Step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
