A. The matrix is not invertible. The given matrix has two pivot positions. B. The matrix is not invertible. If the given matrix is A, the equation Axequalsb has no solution for some b in set of real numbers R cubed. C. The matrix is invertible. The given matrix has three pivot positions. D. The matrix is invertible. If the given matrix is A, there is a 3times3 matrix C such that CIequalsA.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

the answer is a.

135 and 80
