Answer:

C. 20

Step-by-step explanation:

There are 5 possible candidates for president.

After the president is selected, there are 4 remaining possible candidates for vice president.

Therefore, the number of permutations is 4 × 5 = 20.

Answer:

C. 20

Step-by-step explanation:

The order in which the members are selected is important. The first one selected is the president and the second is the vice president.

So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this problem:

2 people are going to be chosen from a set of 5. So

P_{(5,2)} = \frac{5!}{(5-2)!} = 20

So the correct answer is:

C. 20

How many ways can 100 be written as the sum of distinct integers from the set {1, 2,..., 15}?
konstantin123 [22]

Answer:

48 ways

Step-by-step explanation:

Let me take a guess

S₁_₁₅ = (1+15)*7 + 8 = 120

There are 48 combinations of distinct digits from 1 to 15 to make 20

120-20=100

So every 20 has a corresponding 100

I wish I got it right, otherwise report it.

Write a simplified expression using exponents that represents the area of the square.
olganol [36]

Answer:

The area of the square is 25d^{2}.

Step-by-step explanation:

In the given square, the length of the side = 5d.

Area of a square = side × side

Given: Side = 5d

Now plug in side 5d in the above area formula, we get

Area of the square = 5d × 5d

= 25d^{2}

Therefore, the answer is 25d^{2}.
