The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.76, the probability that a car brought into the shop requires brake repair is 0.24, and the probability that a car requires both an oil change and brake repair is 0.18. for a car brought into theshop, determine the probability that the car will require an oil change or brake repair.

0.82

Step-by-step explanation:

Let A denotes the event that the car will require an oil change and B denotes the event that the car require an brake repair.

As per given , we have

P(A)=0.76,    P(B)=0.24    ,   P(A∩B)=0.18

To find : P(A∪B)

Using formula ,

we have

Hence, the probability that the car will require an oil change or brake repair=0.82

-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

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
