Answer:

42

Step-by-step explanation:

<u>First Method</u>

In this case we will substitute w=8 directly into the expression and solve:

7w - 14

When x=8, we get:

7(8) - 14

This gives us:

56 - 14 = 42

<u>Second Method:</u>

This time we factor

7w - 14 = 7(w - 2)

when w=8,

7(8 - 2) = 7 \times 6 = 42

Given P(A) = 0.74, P(B) = 0.6 and P(ANB) = 0.494, find the value of
OverLord2011 [107]

Step-by-step explanation: Since we have given, P(A) = 0.75 and P(A|B) =0.8 .

So, P(A∩B) = P(B|A)× P(A) = 0.8×0.75 =0.6 .

We have given P(B|A') = 0.6

P(A’∩B) = P(B|A')×P(A') = 0.6 × 0.25 = 0.15.

P(B) = P(A∩B) + P(A'∩B) = 0.6 + 0.15 = 0.75.

=> P(A|B) = (∩)()=0.60.75

P

(

A

∩

B

)

P

=

0.6

0.75

= 0.8 .
