For this kind of questions, we need to check the problem carefully...

So there are 45 pupils all in all, and 9 of them gave their sweets away... Therefore, the rest of pupils would be 45-9= 36.

These 36 pupils then got 2 more sweets than they originally have. We can then set x as the number of candies they originally got.

We will then create an equality, since the total number of candies is the same in the 2 scenarios: a) all 45 pupils have candies b) 36 pupils get 2 more

45x = 36(x+2)
45x = 36x + 72
45x - 36x = 72
9x = 72
x = 8 candies

Total number of candies would then be 45x which is 45(8) = 360 candies.

STatiana [176]

Answer:

The number of people who voted is 30 people.

Step-by-step explanation:

Given:

Kim was elected class president. She received 3 votes for every 2 that Amy got.

No one else ran.

However, if 8 of the people who voted for Kim had voted for Amy instead, Kim would have received only 1 vote for every 2 that Amy would have gotten

Find:

the number of people voted

Step 1 of 1

The ratio of Kim's votes to Amy's votes is 3:2, so Kim received 3x votes and Amy received 2x votes for some value of x. If 8 of the people had voted for Amy instead of Kim, then Kim would have 3x-8 votes and Amy would have 2x+8 votes. If this had happened, then Amy would have twice as many votes as Kim, so 2x+8=2(3 x-8).

Expanding the right-hand side gives 2x+8=6x-16.

Subtracting $2 x$ from both sides and adding 16 to both sides gives 24=4x, so x=6.

Since 3x+2x=5x people voted, the number of voters is $5 \cdot 6=30$.

Considering the given discrete probability distribution, it is found that the expected share is of 10%.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

In this problem, the distribution is given by:

  • P(X = 0.05) = 0.2.
  • P(X = 0.1) = 0.6.
  • P(X = 0.15) = 0.2.

Hence the expected value is given by:

E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.

The expected share is of 10%.
