The given graph shows the relationship between the social media posts and grade point average of different students in Brent's class.

From the given graph, we can say that the grade point average of students decrease with increase in number of their social media posts.  

Since grade point average decreases approximately linearly with increase in use of social media posts, It is Strong negative correlation.

Hence, option D is correct i.e. Strong Negative Correlation.

Find the slope between the points (-3, -2) and (5, 4) (type in integer or reduced fraction you found only)
DiKsa [7]

Answer:

The slope is: \frac{3}{4}

Step-by-step explanation:

The equation for slope is:

m=\frac{y_{2}- y_{1} }{x_{2} -x_{1} }

Point 1: -3=x_{1}, -2=y_{1}

Point 2: 5=x_{2}, 4=y_{2}

4-(-2)=6

5- (-3)=8

6/8=3/4

Factor completely. 2x^4+4x^3-30x^2
kramer

Answer:

Step-by-step explanation:

2x⁴ + 4x³ - 30x² = 2x²*(x² + 2x - 15)

x² + 2x - 15

Sum = 2

Product = -15

Factors = 5 ; (-3)

x² + 2x - 15 = x² + 5x - 3x - 3 *5

                  = x(x + 5) - 3(x + 5)

                  = (x + 5)(x - 3)

2x⁴ + 4x³ - 30x² = (2x²) (x + 5)(x - 3)

Is this the correct answer?
Llana [10]

Answer: Choice A) An economic theory that is shared by the discipline of Psychology

Through the research I've found so far, the articles mention that economic choices have a psychological link. This is because economics is basically the study of human psychology (more or less) in terms of how to allocate resources and how best to use them. The law of diminishing marginal utility is basically the idea where the concept "more is always better" is simply not true. An example would be that you are at a restaurant and there's an endless buffet. The food isn't infinite and neither is the capacity of your stomach. After a certain point, you'll find that eating another burger isn't as satisfying as eating the first few burgers. You can think of it as a graph where the curve may start with a sharp increase, but eventually it levels off.

Side note: The term "affective habituation" may be used in psychology textbooks as something very similar to the law of diminishing marginal utility.

How to solve this? Please explain your answer! Thanks!
Murrr4er [49]

Answer:

The mean.

Step-by-step explanation:

I would use the mean as the measure of central tendency.

It is the best representation of the data as the variability isn't high; I'd only use the median if outliers are present because outliers don't affect it.

Because there are no outliers here, the mean is better.

Hopefully I helped :)
