Answer:

A) I = $171.73

B) $4771.73

Step-by-step explanation:

We are told her loan is $4600 for 7 months.

Thus;

Principal; P = 4600

Time; T = 7 months = 7/12 year

Interest rate is given as 6.4%

Thus; r = 6.4

A) To get the interest, the Formula is;

I = PRT/100

I = (4600 × 6.4 × (7/12))/100

I = $171.73

B) Since interest is $171.73, it means amount she owes after the 7 months = $4600 + $171.73 = $4771.73

Answer:0.9991

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where \lambda is the mean of the distribution and x is the number of success

Given : $\lambda=7$

The probability that more than 1 student will have his automobile stolen during the current semester is given by :-

$P(x\geq1)=1-P(x=0)=1-(\dfrac{e^{-7}7^0}{0!})\\\\=1-e^{-7}=0.99908811\approx0.9991$

Hence, the probability that more than 1 student will have his automobile stolen during the current semester =0.9991
