Answer:

D. A Poisson Probability Distribution

Explanation:

Poisson Probability Distribution

This is a probability distribution is used in probability theory and statistics to express the probability of a number of events that occur with a known rate or interval of distance, area, volume or time. Specifically, the Poisson probability distribution named after Simeon Denis Poisson, a French mathematician, is used to express probability where events occur one independent of the other.

Comparing this definition with the waiting line situations, one thing is common, arrivals occur independently of other arrivals and this distribution can be described using the Poisson Probability Distribution.

Alexus [3.1K]

Answer: 12.5 %

Explanation:

Hi, to answer this question we have to apply the simple interest formula:  

I = p x r x t  

Where:  

I = interest (investment after interests - principal; 12000-8000=4000)

P = Principal Amount (initial invest)  

r = Interest Rate (decimal form)  

t= time  

Replacing with the values given  

4,000= 8,000 (x) 4

Solving for x :

4,000= 32,000x

4,000/ 32,000 =x

x= 0.125

Since the interest rate is in decimal form, we have to multiply it by 100 to obtain the percentage.

0.125 x 100 = 12.5 %

Feel free to ask for more if needed or if you did not understand something.

Discount-Mart issued ten thousand $1,000 bonds on January 1, 2018. The bonds have a 10-year term and pay interest semiannually.
blsea [12.9K]

Answer:

The correct answer is 8% annual rate of interest on the bonds.

Explanation:

The effective annual interest rate is 8%

Effective rate if interest (semi-annual) = (Effective interest / Outstanding Balance) x 100

Effective rate if interest (semi-annual) = (345,639 / 8,640,967) x 100

Effective rate if interest (semi-annual) = 0.04 x 100

Effective rate if interest (semi-annual) = 4%

The Effective Annual Rate of Interest = 4% x 2 = 8%
