A school group is raising money for a trip the group needs $450 for travel and $325 for food. They have 6weeks to raise money selling $1 candy bars. What is the least number of candy bars the group needs to sell each week to afford the trip?

130 candy bars

Step-by-step explanation:

In total, the amount of money they will need to raise is:

= 450 + 325

= $775

They have 6 weeks to raise this money so the amount they have to raise per week is at least:

= 775/6

= $130

The candy bars cost $1 each. They will therefore have to sell a minimum of 130 candy bars each week to afford the trip.

you probably already have the answer but anyways it's b. 15.0

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
