Answer:

0.32

Step-by-step explanation:

Use of formula:

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

According to above and based on given:

P(A)P(B|A) = P(B)P(A|B)
P(B|A) = P(A|B)*P(B)/P(A)
P(B|A) = 0.20*0.40/0.25 = 0.32

Answer:

x=5

Step-by-step explanation:

9x^2 - 2x + 25 = 8x^2 + 8x

9x^2-8x^2-2x-8x+25=0

x^2-6x+25=0 factorize

(x-5)(x-5)=0

x-5=0 then x=5

L=length=15.5 ft; W=width; A=area=>170.5 sq ft

L*W=>170.5 sq ft Divide each side by L

W=>170.5 sq ft/L

W=>170.5 sq ft/15.5 ft=>11 feet
