Paul received a 12,000 loan from the bank. The bank charges his 6.99% yearly interest rate. 4 years, how much money does Paul ow
andre [41]
Principal amount = 12,000
Annual interest rate (r) = 6.99% = 0.0699
Time (years) = 4 years
Number of installments (t) = 12*4 = 48 months

Monthly payment, A = P/D

Where,
D= {(1+r/12)^t-1}/{r/12*(1+r/12)^t} = {(1+0.0699/12)^48-1}/{0.0699/12(1+0.0699/12)^48} = 42.47

Therefore, A = 12000/42.47 = 282.59

Total payments after 4 years = 282.59*4*12 = 13,564.17

Interest owed = 13,564.17 - 12,000 = 1,564.17

Ten different numbers are written on pieces of paper and thrown into a hat. The sum of all the numbers is 205. What is the proba
nordsb [41]

Answer:

The probability is 40%

Step-by-step explanation:

a) There are ten pieces of paper with ten numbers

Probability of selecting four pieces of paper = 4/10 or 40%

Probability that the four numbers selected will have a sum greater than 82 = 82/205 = 40%

Therefore, the probability of selecting four numbers that have a sum greater than 82 out of ten numbers totalling 205 is 40%.

b) Probability is the ratio of the number of outcomes favourable for the event to the total number of possible outcomes.   In other words, it is a measure of the likelihood of an event (or measure of chance).
