Answer:
Option C is the correct answer.
Step-by-step explanation:
Since a random number generator is used to select a single number between 1 and 28, inclusively;
For a fair decision to be made during the process, the number of persons in the set must be a divisor of 28.
Let's list the divisors of 28:
The divisors of 28 are {1, 2, 4, 7, 14, 28}
The only option that contains one of the divisors is option C which is 7.
Tyler's $1,000 investment will be worth $1,240 after 6 years, invested at 4% interest rate.
The problem gives the following relevant data:
Principal = $1000
Interest rate = 4% simple interest
Term or time period = 6 years
Since simple interest is given, we need to use the simple interest formula;
I = P x R x T
where: P is the principal, R is the interest rate, and T is the time the money will be invested.
I = $1000 x 4% x 6yrs
I = $1000 x 0.04 x 6
I = 40 x 6
I = 240 ==> Interest earned after 6 years is $240.
Total Investment = Principal + Interest
T.I. = $1,000 + $240
T.I. = $1,240 ==> the value of Tyler's investment after 6 years.

Since 40% of the students prefer chocolate ice cream, 60% don't prefer chocolate ice cream. Use this proportion set equal to 25 to find the number of students who prefer vanilla ice cream, instead of chocolate ice cream.
Answer:
0.1728
Step-by-step explanation:
6^-2= 1/6^2
3^-3= 1/3^3
1/36 * 1/27 * 3.6 * 3.6 * 3.6
= 0.1728
