Answer:

Please check explanations

Step-by-step explanation:

Slopes are generally the ratio of rise(vertical difference) to fall (horizontal difference) for set of points lying on a straight line

Positive slopes show a positive relationship between the two things we are considering while a negative one shows otherwise

They are the same in the sense that they actually represent a constant change between the coordinates of the points in the relationship we are considering.

They are different in the sense that while one represents a positive change, whereby both axes move in the same direction ( rise at same rate, fall at same rate) , the second represent a relationship in which they move in opposite directions. While one falls, the other rises and while the other rises, the second one falls which indicates an opposing movement type between the two

A researcher reports that the probability of a college student living on campus is p = .38. If a small local college has 2,000 s

Olin [163]

Answer:

The standard deviation of the distribution is 21.7 students.

Step-by-step explanation:

We are given the following in the question:

We treat college student living on campus as a success.

P(college student living on campus) = 0.38

Then the number of students follows a binomial distribution.

Sample size, n = 2000

We have to evaluate the standard deviation of the distribution.

Formula:

$\sigma = \sqrt{np(1-p)}$

Putting values, we get,

$\sigma = \sqrt{2000(0.38)(1-0.38)} = 21.7$

Thus, the standard deviation of the distribution is 21.7 students.

A computer programmer's yearly income of $82,000 is increased by 6%. What is the dollar amount of the increase, and what is her

Vinvika [58]

The new yearly income is $86920.
Convert 6% into a decimal which is 0.06.
1ST METHOD:
82000*0.06=4290
4290+82000=86920
2ND METHOD:
0.06+1=1.06
82000*1.06=86920

Use long division to determine the quotient of the polynomials. (x3 – 7x – 6) ÷ (x – 4) Which of the following options best desc

Lelechka [254]

Answer:

The correct option is c.

Step-by-step explanation:

The quotient of the polynomials is

$\frac{(x^3-7x-6)}{x-4}$

We need to find the remainder by using long division method.

The dividend of the given expression is

$Dividend=x^3-7x-6$

$Divisor=x-4$

The long division method is shown below.

$\frac{(x^3-7x-6)}{x-4}=(x^2+4x+9)+\frac{30}{x-4}$

From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.

Therefore the correct option is c.

Which events are independent? Check all that apply. rolling two number cubes at the same time choosing a card, and then flipping

klemol [59]

Independent events are such events where the occurrence of any one event does not affect the occurrence of any other event.

Part A: rolling two number cubes at same time does not affect outcome of any one cube. It would be Independent events.

Part B: choosing a card, then flipping a coin according to favourable outcome can affect the result. It would be dependent events.

Part C: choosing a winner, keeping it, then choosing another name depends upon remaining persons. It would be dependent events.

Part D: drawing a marble, replacing it, then drawing another marble does not affect number of marbles in the bag. It would be Independent events.

Part E: flipping any coin three times does not affect past or future outcomes. It would be Independent events.

Hence, options A, D, and E are Independent events.
