TEA [102]

Answer: 0.2119

Step-by-step explanation:

We assume that the random variable X is normally​ distributed.

Given : Population mean : \mu=100

Standard deviation : \sigma=20

Z-score : z=\dfrac{x-\mu}{\sigma}

Then, z-score corresponds to 116

z=\dfrac{116-100}{20}=0.8

By using the standard normal distribution table for z , we have

P(x>116)=P(z>0.8)=1-P(z\leq0.8)

=1-0.7881446\approx0.2119

Hence, the required probability = 0.2119

A Bank offers an annual simple interest rate of 8% on home improvement loans. Tobias borrowed $17,000 over a period of 2 years.
Alex17521 [72]

We first find out the amount in dollars of interest accrued after 2 years  time.

Interest = Prt

where P is the principal, r is the rate and t is  time

8% written in decimal fraction → 8/100 → 0.08

Interest = 17000 × 8% × 2

Interest = 1700 × 0.08 × 2

Interest =  2,720 dollars

We add the principal and the interest to get full amount paid, so:

17000 + 2,720 = 19,720

I hope that you good day
