The number of different ways that three speakers can be​ selected is 10 ways

Given the names of choice to be Ben, Will, Stewart, Hilary, and Kate. This means that we have a total of 5 name choices.

If the members of students activities are to select three speakers among these people, the number of ways this can be done is by using the combination rule as shown;

nCr=\frac{n!}{(n-r)!r!}

From the question, n = 5 and r = 3. On substituting

5C3=\frac{5!}{(5-3)!3!}\\5C3=\frac{5!}{2!3!}\\5C3=\frac{5 \times 4 \times 3!}{2 \times 3!} \\5C3=\frac{20}{2}\\5C3 = 10 ways

Hence the number of different ways that three speakers can be​ selected is 10 ways.

The figures are similar. What is the value of x? ​
Citrus2011 [14]

Answer: The answer is 18

Step-by-step explanation:

The figures are the same shape, just one is longer. As you can see, the smallest side on the smaller figure is 3 inches. If you look at the larger figure, the smallest side is 6 inches. From this, you can see that you are supposed to multiply the lengths on the smaller figure by 2, to the lengths for the larger figure.

Can someone help me do this
SCORPION-xisa [38]

Answer:

6

Step-by-step explanation:

Find the missing angle:

180⁰ - 82⁰ = 98⁰

Find the sum of the angles given without the missing angle:

180⁰ - 98⁰ = 82⁰

The sum of both the angles is 82⁰

Write an equation:

5x + 8 + 6x + 8 = 82⁰

Collect the like terms together

11x + 16⁰ = 82⁰

Subtract 16⁰ from both sides

11x = 66⁰

Divide by 11 on both sides

x = 6⁰
