Its a good thing this family has "just-in-case" funds because one month their car had two flat tires, and they spent $397.00 to buy new tires! what percent of their monthly income was that expense? (round to the nearest whole percent) monthly income: $3500.00 housing costs: 30% ($1050.00) food: 20% ($700.00) clothing: 10%

Percentage of their monthly income for expenditure on new tires  = 11.34%

Explanation:

Monthly income of the family =  $3500.00

Expenditure on new tires = $397.00

Percentage of their monthly income was that expense = (Expenditure on new tires/ Monthly income of the family) x 100

  Percentage of their monthly income for expenditure on new tires  = (397/3500)x100

                                              = 11.34 %

 So, percentage of their monthly income for expenditure on new tires  = 11.34%

answer: procent 54 wynosi 33,33%

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
