By definition the area of a rectangle is:
A = l * w
Where,
l: long
w: width
So we have to clear the width:
w = A / l
Substituting the values:
w = (234) / (18) = 13
w = 13 feets
answer
the width, in feet, of the room is 13
Answer:
There is enough statistical evidence to support the claim that the survey is not accurate.
Step-by-step explanation:
We have to perform a test of hypothesis on the proportion.
The claim is that the proportion of families that own stock differs from 48.8%.
Then, the null and alternative hypothesis are:

The significance level is 0.05.
The sample. of size n=250, has a proportion of p=0.568.

The standard error of the proportion is

The z-statistic can now be calculated:

The P-value for this two-tailed test is then:

As the P-value is smaller than the significance level, the effect is significant. The null hypothesis is rejected.
There is enough evidence to support the claim that the survey is not accurate.
$30 + $35 = $65
Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)
$65 + $3.90 = $68.90 ($65 + 6%)
OR
You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)
Since you didn't give the original picture, I can only explain the process. Then, you need to select the correct point.
In a dilation, we multiply the coordinates by the scale factor. Take the points that you have and multiply them all by 4. Then, look for a point making your new coordinates.
