Let Events A and B be described as follows: • P(A) = buying a boat

• P(B) = buying a boat trailer

The probability that you buy a boat trailer is 55% The probability of buying a boat trailer

and a boat is 44%. If the probability of buying a boat is 62%, are buying a boat and boat

trailer independent?

No, because P(BIA) = 0.71 and the P(B) = 0.55 are not equal.

No, because P(

AB) = 0.80 and the P(A) = 0.62 are not equal.

Yes, because PAB) = 0.80 and the P(A) = 0.62 are not equal.

Yes, because PB A) = 0.71 and the P(A) = 0.62 are not equal.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
