This is the concept of financial mathematics, the simple interest rate is given by:
S.I.=(PRT)/100
where:
P=principle=$2500
R=rate=5.5%
T=time=1 year
Hence;
S.I.=(5.5*2500.1)/100
=$137.5
Thus the total amount he had after 1 year will be:
2500+137.5
=$2,637.5

A car is designed to last an average of 12 years with a standard deviation of 0.8 years. What is the probability that a car will

Scorpion4ik [409]

Due to the common probability formula I can solve that task. Refering to the task you gave, we have all the information we need. We solve it like that: $\frac{10-12}{0.8} = -2.5; Probability(-2.5)=.0.00621; Probability = 0.621%$
So the answer is the first option 0.621%
