Answer:
She would make $327.60 each week after the raise
Step-by-step explanation:
First we need to find how much she will make per hour. We can do this by multiplying the per hour rate by the percentage of the raise.
$7.65 * 7% = $0.54
Now we add this amount to the previous hourly rate.
$7.65 + $0.54 = $8.19
Now that we have the new hourly rate, we multiply it by the number of hours that she works.
$8.19 * 40 = $327.60
Answer:
4.4444 percent.
Step-by-step explanation:
1cm = 10mm
So 9cm would equal out to 90mm ...
4 mm would be 4.44 percent of the 9cm.
is (4) % (?)
of (90) 100
Cross X mutiply and divide..
4x100 = 400
90 x % = 90... & 400 divided by 90 = 4.444
$250 - $5x = Amount of Money left
Hope this helps!

Step-by-step explanation:
Answer:
The margin of error is 3.97 percentage points.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

95% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The margin of error is the upper limit subtracted by the proportion, or the proportion subtracted by the lower limit. They are the same values.
So the margin of error is 0.5997 - 0.56 = 0.56 - 0.5203 = 0.0397 = 3.97 percentage points.
