Answer:

B) (3,1)

Step-by-step explanation:

y = -2x + 7

y = 3x - 8

3x - 8 = -2x + 7

combine like terms:

5x = 15

divide both sides of the equation by 5:

x = 3

y = 3(3) - 8 = 1

NemiM [27]
You add 25 to both sides.
You take half the x term, which is 10/2=5, and square it, so 25.

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.

Is -0.28764 rational or irrational and how do you figure that out?
kvv77 [185]
It is rational. Any number that can be described as a fraction is rational while those that do not are irrational.

-0.28764 is the same as -(28764/100000) and positive, negative does not matter.
