the area of a rectangular pyramid is 65yd^2. the length of the playground is 3 yards longer than twice it's width. find the leng

schepotkina [342]

The area formula for a rectangle = Length x Width
Let length = L and width = W.
We also know that the length is 3 yards longer than twice it's width.
SO this means L = 3 PLUS 2 times W
L = 3 + 2W
Now plug that into the area formula and we get:
Area = (3 + 2W) x W
You'll need to multiply everything in the brackets by W.
So what would (3 + 2W)x W = ?

P(A)= .50 P(B)=.80 P(A and B)=.20 what is P(B/A)

Reil [10]

Answer:

Final answer is $P(B|A)=0.40$ .

Step-by-step explanation:

Given that P(A)= .50, P(B)=.80 , and P(A and B)=.20.

Now we need to find about what is the value of P(B/A).

So apply the formula of compound probability :

P(A and B) = P(A)*P(B/A)

Plug the given values into above formula

0.20 = 0.50*P(B/A)

0.50*P(B/A) = 0.20

$P(B|A)=\frac{0.20}{0.50}$

$P(B|A)=0.40$

Hence final answer is $P(B|A)=0.40$ .
