Which of the following is the solution to the following systems of inequalities? (picture included)
Ymorist [56]

Answer:

  C.  (see the attachment)

Step-by-step explanation:

Both inequalities include the "or equal to" case, so both boundary lines will be solid. That excludes choices A and D.

The first inequality is plotted the same way in all graphs, so we must look at the second inequality. The relationship of y and the comparison symbol is ...

  -y ≥ (something)

If we multiply by -1, we get ...

  y ≤ (something else)

This means the solution space will be <em>on or below (less than or equal to) the boundary line</em>. This is the shaded area in graph C. (Graph B shows shading <em>above</em> the line.)

___

<em>Further comment</em>

Since the boundary for the second inequality is fairly steep, "above" and "below" the line can be difficult to see. Rather, you can consider the relationship of x to the comparison symbol. For the second inequality, that is ...

  x ≥ (something)

indicating the solution space is <em>on or to the right of the boundary line</em>.

Students recorded the total number of pages and chapters in each of several books on the scatterplot.
lisabon 2012 [21]

Answer:

120

Step-by-step explanation:

based on the plot the closest number to the patter seem to be around 100 but its not 90 as 90 would be below so it has to be about 12

The children from a football club are put into rows in the sports hall.When out in rows of 9 children, there are 2 children left
Anettt [7]

Answer:

The least number of children in the football club is 38.

Step-by-step explanation:

If children put in rows of 9, left out children = 2

If children put in rows of 12, left out children = 2

We will find least number of children in football club by finding LCM of 9 and 12.

Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63,...

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,...

As we can see here: The LCM  of 9 and 12 is 36.

We are told that 2 children left over from putting them into 9 and 12 children per row. To find least number we will add 2 to 36.

Therefore, the least number of children in the football club is 38.

In a normal distribution with μ=14 and σ=2, find the mean of the distribution of sample means for samples of size 25
alexandr402 [8]

The mean of the distribution of sample means for samples of size 25 is <u>μₓ = μ = 14</u>.

The central limit theorem implies that the distribution of the sample means will be roughly normally distributed if you have a population with mean μ and standard deviation σ and take sufficiently enough random samples from the population with replacement. This holds as long as the sample size is sufficient (often n > 30), regardless of whether the source population is normal or skewed. The  Theorem is valid even for samples less than 30 if the population is normal.

Using the population's random samples as a source, we may calculate:

The mean of the sample means μₓ = μ, and

the standard deviation of the sample means σₓ = σ/√n.

In the question, the population is normally distributed. Thus, we can use the central limit theorem, which gives that the mean of the sample means: μₓ = μ, making the mean of the distribution of sample means for samples of size 25 = μ = 14.

Thus, the mean of the distribution of sample means for samples of size 25 is <u>μₓ = μ = 14</u>.
