Answer:

Being a student and preferring “shark” are not independent events

Step-by-step explanation:

Let A be the event that the selected person is a student and B the event that person prefers sharks.

Total number of students =100

Hence P(A) =\frac{100}{115} =0.8696

P(B) = Persons who prefers sharks /total persons

=\frac{95}{115} =0.8261

P(AB) = no of persons who are students and who prefer sharks/total persons

= \frac{90}{115} =0.7826

P(A)P(B) = =0.8696*0.8261\\\\=0.7183

Since P(AB) does not equal P(A) P(B), we find that

A and B are not independent.

Being a student and preferring “shark” are not independent events

Which of the following is the most appropriate unit to describe the rate at which people are entering a theme park?
ad-work [718]

The <u><em>correct answer</em></u> is:

d) People per hour, because the dependent quantity is the people

Explanation:

In this situation, the two quantities are people and hours. These are the two things in this problem we can count or measure.

The independent variable is the one that causes a change, while the dependent variable is the one that <em>gets</em> changed. In this situation, the number of people change every hour; this means the number of people <em>gets</em> changed, which makes it the dependent variable. This means that the independent variable must be time.

Since people is dependent and time is independent, "people per hour" would be the best form of this statement.

Answer:

(x - 1) (x + 2) (x + 4)

Step-by-step explanation:

Factor the following:

x^3 + 5 x^2 + 2 x - 8

The possible rational roots of x^3 + 5 x^2 + 2 x - 8 are x = ± 1, x = ± 2, x = ± 4, x = ± 8. Of these, x = 1, x = -2 and x = -4 are roots. This gives x - 1, x + 2 and x + 4 as all factors:

Answer: (x - 1) (x + 2) (x + 4)
