Don't solve all the equations, you're given the answer to x so just substitute.

5/2*8+7/2=3/4*8+14

23.5=20 INCORRECT

5/4*8-9=3/2*8-21

1=-9 INCORRECT

5/4*8-2=3/2*8-4 <- YOUR ANSWER

8=8 CORRECT

Graph the set of points. which model is most appropriate for the set (-6 4) (-4 0) (-3 -2) (-1 -7)
Free_Kalibri [48]

Answer:

The linear regression model is y=-2.19x-8.92.

Step-by-step explanation:

The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.

From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.

The general linear regression model is

y=ax+b

Using technology we get

a=-2.1923076923\approx -2.19

b=-8.9230769231\approx -8.92

Put a=-2.19 and b=-8.92 in  the above equation.

y=-2.19x-8.92

Therefore the linear regression model is y=-2.19x-8.92.

kherson [118]

Answer:

A. Continuous, B. Discrete, C. Continuous, D. Continuous, E. Continuous.

Step-by-step explanation:

A. Area is a continuous unit. Then, the floor area of a kitchen is a continuous random variable.

B. Quantity is a discrete unit. Then, the number of bacteria in a particular cubic centimeter of drinking water is a discrete random variable.

C. The money amount is a continuous unit. Then, the dollar amount of the change in my pocket is a continuous random variable.

D. The pressure is a continuous unit. Then, the barometric pressure at a given location is a continuous random variable.

E. Time is a continuous unit. Then, the difference in reaction time to the same stimulus before and after training is a continuous random variable.
