Answer:
future payment is $77056.92
total interest is paid after 45 year is $23056.42
Step-by-step explanation:
Given data
payment (P) = $100
No of installment (n) = 12
rate of interest ( r ) = 1.5 % i.e. = 0.015
time period (t) = 45 years
to find out
future payment and interest after 45 year
solution
we know future payment formula i.e. given below
future payment = payment ×
now put all these value in equation
future payment = $ 100 ×
future payment = $ 77056.92
payment paid in 45 year @ $100 total money is paid is 45 × 12 × $100 i.e. = $54000
total interest = future payment - money paid
total interest = $77056.42 - $54000
total interest = $23056.42
Answer: It is mutually exclusive and exhaustive.
Step-by-step explanation:
Since we have given that
Owns apple No apple Total
With kids 500.2 319.8 820
Without kids 182.4 197.6 380
Total 682.6 517.4 1200
P(Households without kids) =
P(Households with kids) =
And P(A∪B) = 0.316+0.683 = 0.999 ≈ 1
Since the two event are disjoint so, the probability of both occurring is 0 and the probability of either occurring is the sum of each occurring.
Hence, it is mutually exclusive and exhaustive.
