Answer:

423

Step-by-step explanation:

Start by setting up a formula.

x = the shorter piece

total = 1313

longer piece = (x*2) + 44

x + (x*2) + 44 = 1313

Simplify

3x + 44 = 1313

Now we must solve for x.

Whatever you do on the left side of the equal sign must also be done on the right.

The goal is to get x by itself on the left side.

Do the easiest thing first, which is usually addition or subtraction. In this case, subtract 44 from both sides.

3x + 44 - 44 = 1313 - 44

3x = 1269

Now the only way to cancel out the 3 on the left is to divide by 3. Since 3/3 =1. Remember this must be done on both sides to keep things equal.

3x/3 = 1269/3

x=423

The End

Answer/Step-by-step explanation:

<u>Given:</u>

Bracelets - $3

Necklaces - $6

<u>To Find:</u>

Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry. Write the ordered pair for the corresponding terms in the third column. Then graph the ordered pairs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<u>Solve: </u>Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry.

<u>Bracelets:  </u>                                                      <u> Necklaces:</u>

0 = $0                                                               0 = $0

1= $3                                                                  1 = $6

2=$6                                                                  2 = $12

3=$9                                                                   3 = $18

4=$12                                                                  4 = $24

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<u><em>Solve: </em></u>Write the ordered pair for the corresponding terms in the third column.

Ordered Pair -

Two numbers written in a certain order.

Usually written in parentheses like this:

(12,13)

Where they cross over is the "0" point,

we measure everything from there.

The X Axis runs horizontally through zero

The Y Axis runs vertically through zero

(x, y )

Since it asking for Write the ordered pair for the corresponding terms in the third column.

Thus,

- Number of jewelry to cost -

we have:

Bracelets ⇒ ( 3, 9)

Necklaces ⇒ (3, 18)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then graph the ordered pairs.

The population standard deviation for the typing speeds for secretaries is 4 words per minute. If we want to be 90% confident th
Oksana_A [137]

Answer:

The minimum sample size that should be taken is 62.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

If we want to be 90% confident that the sample mean is within 1 word per minute of the true population mean, what is the minimum sample size that should be taken

This is n when M = 1, \sigma = 4. So

M = z*\frac{\sigma}{\sqrt{n}}

1 = 1.96*\frac{4}{\sqrt{n}}

\sqrt{n} = 4*1.96

(\sqrt{n})^{2} = (4*1.96)^{2}

n = 61.5

The minimum sample size that should be taken is 62.
