Matthew has $45 in savings and plans to save an additional $30 each month. How long will it take him to save enough for a $250 bike? What is the equation in this situation? O 250 = 450 + 30
O 250 = 30.2 + 45
O 30 30 = 2502 + 45
O 30-45x+250

Part A. It will take him 7 months

Part B. The equation is 30 - 45x + 250

Step-by-step explanation:

Part A. the answer is 7 because in 6 months Matthew will have $225 and if you add 30 you get $255.

Part B. It's the answer because its the only one that makes sense. 250 = 450 + 30. Its 45 not 450. 250 = 30.2 + 45. It's 30 not 30.2 and 30 30 well 30 30 doesn't make sense either.

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
