Which of the following expressions is equal to -x2 - 36?

1 answer:

6 0

A
when you break the equation down, you want to make sure it still will have the same signs. so, if you have a -2x then you r going to have one with a -x and one with a +x and to make the 36 negative you have to have one with a -6 and one with a +6

Answer:

Step-by-step explanation:

a). Given equation is y = 3x - 4

Table for the input-output values is,

x -1 0 1 2 3

y -7 -4 -1 2 5

Now we can plot these points on the graph (graph attached).

b). Equation is y = -2x + 3

Table for the input-output values will be,

x -1 0 1 2 3

y 5 3 1 -1 -3

If 33% of the members of Sweetheart Union sign petitions to decertify the union, the National Labor Relations Board will call an

Elis [28]

Answer:

There is no need to call for election.

Step-by-Step Explanation

Surveys are based on probability or statistics. It serves as a standard tool for experimental research in marketing, social sciences and official data statistics.

Since 8 out of 40 members of the Sweetheart Union will sign the petition, the percentage of those who will sign the petition is calculated below:

$\frac{8}{40}*100=20\%$

Based on the sample survey, only 20 percent of the members will sign the petition. Since, in the sample, the number of those who will sign is less than 33%, the union should be told that there is no need for the National Labor Relations Board to call for the election.

An experiment is to be conducted using environmentally safe peppermint oil to study the effectiveness of deterring mice from inf

shutvik [7]

Answer:

Option E is correct.

- Treatments: how the peppermint oil is dispersed

- Experimental unit: mice

- Response variable: number of mice in the dwellings

Step-by-step explanation:

The treatments in this type of statistical experiment refers to the part of the experiment that is tweaked, controlled or varied in the cases being studied. In this experiment, the method of essential oil dispersal is what is varied in the two experimental cases of this study.

Experimental Unit refers to the subject matters, who are participants in the experiment. They are the ones that the effect of the treatments is tested upon.

For this study, the experimental units are the mice subjected to either of the two methods of peppermint oil dispersal.

The response variable is how the experimental units (participants) respond to the treatments (experimental tweaks). Or how the tweaks manifest observable results in the participants of the study. For this study, the effect of the tweaks in the mice is shown in the number of mice that remain in each dwelling (where the two methods of peppermint oil dispersal have been implemented). Hence, the response variable is the number of mice in each dwelling.

Hope this Helps!!!
