Answer: $2926.05

Step-by-step explanation:

Compounded interest follows the formula:

P(1 + r/n)^nt where P = principle, or starting contribution, R = Rate (Percentages converted to decimals), N = number of compounds per year, and T = number of years.

The Principle would be $2500

The Rate would be 2.64% or 0.0264

N would be 2, since it is semiannual

T would be 6, since this lasts 6 years.

When we plug it in, we see

2500(1 + (.0264/2))^(2)(6)

= 2926.053

In a real situation in the bank, they would give you $2926.05

You have 5 55 reindeer, Bloopin, Rudy, Ezekiel, Prancer, and Balthazar, and you want to have 3 33 fly your sleigh. You always ha
sweet-ann [11.9K]

Answer:

60 different ways.

Step-by-step explanation:

We have been given that you have 5 reindeer, Bloopin, Rudy, Ezekiel, Prancer, and Balthazar, and you want to have 3 fly your sleigh. You always have your reindeer fly in a single-file line. We are asked to find the number of ways in which we can arrange reindeer.

We will use permutations to solve our given problem.

The number of way to choose r objects from a set of n objects is ^nP_r=\frac{n!}{(n-r)!}.

Upon substituting our given values in permutations formula, we will get:

^5P_3=\frac{5!}{(5-3)!}

^5P_3=\frac{5!}{2!}

^5P_3=\frac{5\times 4\times 3\times 2!}{2!}

^5P_3=5\times 4\times 3

^5P_3=60

Therefore, you can arrange your reindeer in 60 different ways.

tatiyna

Answer:

12 students

Step-by-step explanation:

Given that:

Eighth grade student = 72

Sixth grade student = 84

To group the students into the largest possible equal group with no student left, obtain the greatest common factor of the number of sixth grade and eighth grade student

Factors of 72:

72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36

84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 81

The greatest factor common in both numbers is 12.

A study shows that employees who begin their workday at 9:00 a.m. vary their times of arrival uniformly from 8:40 a.m. to 9:30 a
jeka94

Answer:

0.2 or 20%

Step-by-step explanation:

If the times of arrival vary uniformly, there is an equal chance of an employee reporting at any given time between 8:40 and 9:30.

The range between 8:40 and 9:30 is 50 minutes.

The range between 9:00 and 9:10 is 10 minutes.

Therefore, the  probability that a randomly chosen employee reports to work between 9:00 and 9:10 is:

P(9:00\leq X\leq 9:10)=\frac{10}{50}=0.20=20\%

The probability is 0.2 or 20%.
