Using the horizontal line test, which of the following can be concluded about
Helen [10]

Step-by-step answer:

A vertical line test checks for single or multiple intersections with a given relations  If there is a maximum of one intersection with the relation at ANY point in the domain of the relation, we can conclude that the relation is a function.  If there are multiple intersections of a VERTICAL line with the function, it is not a function.

Here, we see that vertical line test on the relation shown does not produce more than one intersection at any point in the domain of the relation, hence we conclude that the graph shows a function.

An inverse of a function is a reflection of the function about the y=x line.  The result is the same as the interchange of the x and y-axes.

Hence a horizontal line test on the inverse of a function gives the same results as a vertical line test of the function itself, and the conclusion is identical to the test given above in paragraph two.

sergejj [24]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

H_0: Management quality and corporate reputation are independent.  

H_1:  Management quality and corporate reputation are not independent.

Test statistic:

\to \chi^2 = \frac{\sum (O-E)^2}{E}

= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333    +0+3.2143+7.5\\\\= 17.02806

The critical \chi^2 fordf = (r-1)(c-1) = (3-1)(3-1)= 4 and \alpha = 0.05 is \chi^2= 9.4877

Test statistic:

17.02806 > 9.4877 therefore rejecting the null hypothesis H_0.

p-value= 0.001909

Interpretation:

There is no internal governance quality as well as the reputation of the organization.

Sorry it’s small I could not get it in just zoom in
Ne4ueva [31]

Hello!

Graphs A and D are reflected, not rotated, so they are not the answer.

Graph C is rotated 180°, so it is not the answer.

This leaves us with B as our final answer.

I hope this helps!

A video store rents new movies for $5 and older movies for $4. The owner wants
AnnyKZ [126]

Answer:

2480 new movies

Step-by-step explanation:

1) First you need to find out how much money the 400 older movies made.

400*4=1600

2) Next subtract that amount from the amount of revenue that the wants.

14000-1600=12400

3) Divide the amount of leftover money by the amount that a new movie costs to rent

12400/5=2480

This means that in order to reach the desired amount of revenue the store must sell 2480 new movies.
