Answer:
Step-by-step explanation:
Simple interest is given as
S.I = PRT/100
Where
S.I is simple interest
R is rate in %
P is the principal
And T is time in years
So, given that
Principal (P)=£1500
Rate(R) =2%
Time(T)= 3years
Then, we are asked to find amount after 3years
S.I=PRT/100
S.I=1500×2×3/100
S.I= £90
This is the interest Brian will receive
So, the money will amount to
Amount=Principal + interest
Amount = 1500+90
Amount = £1590.
So Brian will have £1590 after 3years
Answer:
0.0244 (2.44%)
Step-by-step explanation:
defining the event T= the chips passes the tests , then
P(T)= probability that the chip is not defective * probability that it passes the test given that is not defective + probability that the chip is defective * probability that it passes the test given that is defective = 0.80 * 1 + 0.20 * 0.10 = 0.82
for conditional probability we can use the theorem of Bayes. If we define the event D=the chip was defective , then
P(D/T)=P(D∩T)/P(T) = 0.20 * 0.10/0.82= 0.0244 (2.44%)
where
P(D∩T)=probability that the chip is defective and passes the test
P(D/T)=probability that the chip is defective given that it passes the test
When Sam is 13 his mother will be 39 which is 3 times as old as he is. So Sam's mother will be 3 times as old as Sam will be in 11 years. (Your answer is 11 years.)
