Jake accumulated $8,000 in credit card debt. if the interest rate is 20% per year

8,000 x .02 = 1,600

Step-by-step explanation:

Convert the percentage by dividing 20% by 100 to get 0.2,

Then multiply by 8,000 to get your answer.

$14,366.85

Step-by-step explanation:

Identify the values of each variable in the formulas. Remember to express the percent as a decimal.

A=?

P=$8,000

r=0.2

t=3

For quarterly compounding, n=4. There are 4 quarters in a year.

A=P(1+rn)nt

Substitute the values in the formula.

A=8,000(1+0.24)4⋅3

Compute the amount. Be careful to consider the order of operations as you enter the expression into your calculator.

A=$14,366.85

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
