Aileen can read 1.5 pages for every page her friend can read. Aileen's mom was very excited and she said to Aileen: "So, if your

friend reads 20 pages, you can read 25 in the same time period!" Is Aileen's mom correct?

Yes because 20+1.5 equals 25

Answer:

{2, 4, 6}

Step-by-step explanation:

the domain is the interval or set of valid x (input) values.

the range is the interval or set of valid y (result) values.

just use the x values in the functional definition and collect the results. these are the range.

x = -1

y = 2×-1 + 4 = 2

x = 0

y = 2×0 + 4 = 4

x = 1

y = 2×1 + 4 = 6

Sketch a graph of −3x+y=2

DIA [1.3K]

You can do this by first finding the y intercept which is the point where x = 0

-3(0) + y = 2
so y intercept is the point (0,2)

Now find the x intercept by putting y = 0

-3x = 2

x = -2/3

So we have 2 points (-2/3, 0) and (0,2) Draw a line through these 2 points and you have the required graph.

The following estimated regression equation was developed for a model involving two independent variables.

Alik [6]

Answer:

(a): y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second

(b): Yes

Step-by-step explanation:

Given

$\wedge y = 40.7 + 8.63x_1 +2.71x_1$

$\wedge y = 42.0 + 9.01x_1$

Solving (a): An interpretation of x1 coefficient

We have the coefficients of x1 to be 8.63 and 9.01

Literally, the coefficient represents the average change of y-variable per unit increase of the dependent variable

Since the coefficients of x1 in both equations are positive, then that represents an increment on the y variable.

So, the interpretation is:

y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second

Solving (b): Multicollinearity

This could be the cause because x1 and x2 are related and as a result, x2 could take a part of the coefficient of x2

The perimeter of a stop sign with 8 sides of equal length is 8n. What does the variable "n" represent?

andriy [413]

The "n" in this expression will stand for the length of the sides.

Because we know there are 8 sides so 8xn will give us the perimeter.
