The first thing you should do in this case is to know how much paper you need to print for the 17 copies.
 We have then:
 (17) * (130) = 2210
 Then, you must calculate the number of reams you need:
 n = (2210) / (500) = 4.42
 You need 4 full reams and 42% of a fifth ream. So, the cost will be
 C = (4.42) * (3.44) = 15.2048 $
 The unit cost of each paper is:
 Cu = (15.2048) / (2210) = 0.00688 $
 answer
 the paper is going to cost 0.00688 $ for those reports

Answer:

Cost of paper for all the reports which are to be printed = $15.20

Step-by-step explanation:

Length of the work report = 130 pages

Now, number of copies to be printed for meeting = 17

So, total number of pages needed to be printed = no. of copies × length of each report

⇒ Total number of pages = 17 × 130

                                          = 2210

Now, cost of 500 pages = $3.44

\text{Cost of 1 page = }\frac{3.44}{500}=\$0.00688\\\\\text{Cost of 2210 pages = }2210\times 0.00688=\$15.20

Hence, Cost of paper for all the reports which are to be printed = $15.20

Write 1/3 as a power with an integer base
Viefleur [7K]

Answer:

3^{-1}

Step-by-step explanation:

Using the rule of exponents

\frac{1}{a^{n} } ⇔ a^{-n}

Given

\frac{1}{3} = \frac{1}{3^{1} } = 3^{-1}

I need to find how many solutions does the system have. ​
REY [17]
From what I got there is one real solution :)

Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)

Also they are both straight line graphs so they will either have one or no solutions

Hope this helped :)

A road sign is in the shape of a regular pentagon. What is the measure of each angle on the sign? Round to the nearest tenth. Se
dangina [55]

Answer:

Option D) 108 degrees

Step-by-step explanation:

We are given the following in the question:

A regular pentagon.

Thus, all the angles of the pentagon are equal.

Angle sum property of pentagon:

  • In a pentagon, the sum of all the interior angle of a pentagon is 540 degrees.

Measure of each angle =

=\dfrac{\text{Measure of angle}}{\text{Number of angle}} = \dfrac{540}{5} = 108^\circ

Thus, the measure of each angle on the sign is 108 degrees.

Option D) 108 degrees

Assume, for the sake of this question, that the data were collected through a well-designed, well-implemented random sampling me
amid [387]

Answer:

Since the pvalue of the test is 0.2743 > 0.1, the threshold probably was met.

Step-by-step explanation:

The widget manufacturing company had established a threshold of 60% preferring the proposed new widget to move forward with producing the new widgets.

This means that at the null hypothesis we test if the proportion is at least 60%, that is:

H_{0}: p \geq 0.6

And the alternate hypothesis is:

H_{a}: p < 0.6

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

0.6 is tested at the null hypothesis:

This means that:

\mu = 0.6

\sigma = \sqrt{0.6*0.4}

Three hundred thirty-eight of 575 respondents reported preferring the proposed new widget.

This means that n = 575, X = \frac{338}{575} = 0.5878

Value of the test-statistic:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{0.5878 - 0.6}{\frac{\sqrt{0.6*0.4}}{\sqrt{575}}}

z = -0.6

Pvalue of the test and decision:

We want to find the probability of a proportion of 0.5878 or lower, which is the pvalue of z = -0.6.

Looking at the z-table, z = -0.6 has a pvalue of 0.2743.

Since 0.2743 > 0.1, the threshold probably was met.
