The revenue, in thousands of dollars, that a company earns selling lawnmowers can be modeled by R(x)=90x-x^2 and the company's total profit, in thousands of dollars, after selling x lawnmowers can be modeled by P(x)=-x^2+30x-200. Which function represents the companys cost, in thousands of dollars, for producing lawnmowers?(Recall that profit equals revenue minus cost.) A. C(x)=-60x^2-200 B. C(x)=60x+200 C. C(x)=2x^2+60x+200 D. C(x)=-2x^2-60x-200

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
