10. a company makes calendars from personal photos. you pay a delivery fee for
each order plus a cost per calendar. the cost of 2 calendars plus delivery fee is $43.
the cost of 4 calendars plus delivery is $81. (a)write an equation that gives the
total cost as a function of calendars bought. (b)what is the delivery fee? (c)what is
the cost per calendar?

the answer is 62

what "following statement"?

step-by-step explanation:

c. side angle side. u shares the same sides

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
