Answer: they have to sell 880 books to break even.

Step-by-step explanation:

Let x represent the total number of books that Richmond high school produced and also sold.

Richmond high school is paying $13,200 for the writing and research of their yearbook plus a printing fee of $25 per book. This means that the total cost of producing x books would be

25x + 13200

if they sell the books at $40 each, it means that the total revenue would be

40 × x = 40x

The break even point is the point at which income equals expenses expenses. Therefore,

25x + 13200 = 40x

40x - 25x = 13200

15x = 13200

x = 13200/15

x = 880

grigory [225]

Answer:

14b

Step-by-step explanation:

Here, we want to get the greatest common factor of the two terms

The greatest common factor can be obtained by finding the expression that factor the given expression

We have this as;

14b(2a + 3)

So the greatest common factor is 14b

Answer:

6x²y(9 - 2y)

Step-by-step explanation:

Step 1: Factor out GCF

6(9x²y - 2x²y²)

Step 2: Factor out <em>x²</em>

6x²(9y - 2y²)

Step 3: Factor out <em>y</em>

6x²y(9 - 2y)

And we have our factored answer.

The National Center for Education Statistics reported that 47% of college students work to pay for tuition and living expenses.
Luden [163]

Using the z-distribution, it is found that the 95% confidence interval for the proportion of college students who work to pay for tuition and living expenses is: (0.4239, 0.5161).

If we had increased the confidence level, the margin of error also would have increased.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

In this problem, we have a 95% confidence level, hence\alpha = 0.95, z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96. Increasing the confidence level, z also increases, hence the margin of error also would have increased.

The sample size and the estimate are given as follows:

n = 450, \pi = 0.47.

The lower and the upper bound of the interval are given, respectively, by:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.47 - 1.96\sqrt{\frac{0.47(0.53)}{450}} = 0.4239

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.47 + 1.96\sqrt{\frac{0.47(0.53)}{450}} = 0.5161

The 95% confidence interval for the proportion of college students who work to pay for tuition and living expenses is: (0.4239, 0.5161).
