Given P(A)=0.39P(A)=0.39, P(B)=0.5P(B)=0.5 and P(B|A)=0.8P(B∣A)=0.8, find the value of P(A\cap B)P(A∩B), rounding to the nearest thousandth, if necessary.

step-by-step explanation:

sorry i just need to anwers this to get points

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
