Answer:

-3(-5+2x)+x

Step-by-step explanation:

First you have to use Distributive Property and multiply -5 and 2x by -3. you should have -6x+15+x. then you have to combine like terms but subtract -6x and x which gives us 5. your answer should be -5x+15. You can rearrange the answer to be 15 - 5x.

1)-5(x-3)= -5x+15
2) 3(5-x)= 15-3x
3) -5(3-x)= -15+5x
4)-3(-5+2x)+x=-5x+15
5)5(3-x)= 15-5x
Your answer would be 5) 5(3-x).

Savatey [412]

Answer:

The mean number of the students who develop hypertension over a life time is 7.8.

Step-by-step explanation:

For each person, there are only two possible outcomes, either they will develop hypertension, or they will not. The probability of a person developing hypertension is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

Suppose that the probability that a person will develop hypertension over a life time is 60%.

This means that $p = 0.6$

13 graduating students from the same college are selected at random.

This means that $n = 13$

Find the mean number of the students who develop hypertension over a life time

$E(X) = np = 13*0.6 = 7.8$

The mean number of the students who develop hypertension over a life time is 7.8.

My sister is 2 years older than I am. The sum of our ages is 32. Find our ages.

VikaD [51]

Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30
x = 15

Your age is 15 and your sisters is 17
