Student Council is sponsoring a dance and wants to hire a DJ. The company they called has two price plans to choose from.

Plan 1: $150 for set-up and transportation, plus $65 per hour
Plan 2: $80 per hour, but no set-up and transportation fee

Which system of equations can be used to find x, the number of hours the DJ
must play for both plans to cost the same?

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

umm im not really sure because i never had to do this
