A company earns a weekly profit of P dollars by selling items, according to the equation P(x) = -5x2 + 400x . What is the maximum profit? How many items have to be produced to earn zero profit.

2,600 divided by 80 = 32.5

step-by-step explanation:

answerthe vertex form

step-by-step explanation:

85.560%

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

6 and 24

step-by-step explanation:

6 x 4 = 24
