A professor wanted to find a linear model that relates the number of hours a student plays video games each week, h, to the cumu

lative grade point average G of the Hours of Video Games student. He obtained a random sample of 10 full-time students at his college and asked each student to disclose the number of hours spent playing video games and per Week, h the student's cumulative grade-point average. Complete parts (a) through (1) below. Grade point Average, G 3.69 285 3.54 262 2.99 NNNNN1. Explain why the number of hours spent playing video games is the independent variable and cumulative grade-point average is the dependent variable. Choose the correct answer below. A. The number of hours is being used to predict Cumulative grade-point average .B. Cumulative grade-point average is being used to predict the number of hours.C. The number of hours and the cumulative grade-point average are unrelated.D. The number of hours is directly related to the cumulative grade-point average.

Answer:

question seems incomplete but with the limited information one can deduce that the professor was trying to investigate how students CGPA is affected by the length of period spent on video games.  

A

Step-by-step exp

independent variables are constants. they do not change or depend on any other variable.

dependent variables, they do depend on other variables, we call them resulting variables..

Help please. I'll give the Brainliest.
sdas [7]

Answer:

Options 1,2,3 are correct statements

The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)

The second values are the range : (-1,1,2,3,4,5)

One input should have only one output for a function.

But -1 input has 2 outputs: -1 and 3.

Thus, it is a relation and not a function.

Hope it helps :)

A large energy company produces electricity, natural gas, and oil. The production of a dollar's worth of
HACTEHA [7]

Answer:

E = 64.05

NG = 52.29

O = 35.15

Step-by-step explanation:

With the statement we can create a system of 3X3 equations that would be as follows:

E = electricity

NG = natural gas

O = oil

0.35 * E + 0.15 * NG + 0.25 * O = 25

0.35 * E + 0.15 * NG + 0.2 * O = 15

0.1 * E + 0.1 * NG + 0.1 * O = 20

If we pass this system equations to matrix and subtract it from the identity matrix we would have the following:

0.65 * E - 0.15 * NG - 0.25 * O = 25

-0.35 * E + 0.85 * NG - 0.2 * O = 15

-0.1 * E - 0.1 * NG + 0.9 * O = 20

Solving this system of equations around here can be very long and impractical, therefore, I attach a photo of the process:

And the answer is:

E = 64.05

NG = 52.29

O = 35.15
