Answer:

The unit rate of y per x is 9

Step-by-step explanation:

In this question, we are asked to give the unit rate of x.

To do this, we will critically look to establish the relationship between both set of values.

Looking at the values critically, we can see that the values in the first brackets, when multiplied by 4 will give the values in the second bracket. Hence we can say that the values in the second bracket are multiples of the first by 9.

Assume that when Human Resource managers are randomly selected, 62% say job applicants should follow up within two weeks. If 25
stellarik [79]

Using the binomial distribution, it is found that there is a 0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

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

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

The values of the parameters are given as follows:

n = 25, p = 0.62.

The probability that exactly 18 of them say job applicants should follow up within two weeks is P(X = 18), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 18) = C_{25,18}.(0.62)^{18}.(0.38)^{7} = 0.1008

0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

2x - x + 9 + 3x - 2 = 16
Mrac [35]

Answer:

x = 9/4 or 2.25

Step-by-step explanation:

First you will combine like terms. Combine 2x + 3x - x which gives you 4x. Then combine 9 - 2 and you get 7. Now the equation is 4x + 7 = 16. Subtract 7 from both sides to get x by itself. Now you have 4x = 9. To find what x equals, divide by 4 on each side. x = 9/4 or 2.25
