Suppose that the three inspectors in a film factory are supposed to stamp the expiration date on each package of film at the end of the assembly operation, after each package passes inspection. The four inspectors, however, miss some packages. John, who inspects 45 percent of the packages, misses the stamp on 1 in 11 packages. Mindy, who inspects 5 percent of the packages, misses the stamp on 1 in 19 packages. Alice, who inspects 50 percent of the packages, misses the stamp on 1 in 30 packages. What is the probability that a randomly selected package is missing the expiration date

-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

the diameter is 16 cm. are you a teacher?

i think it might be a but you might want a second opinion
