hours on Sunday and earned 1.5 times her normal hourly rate because it was a holiday. She spent $8.50, at the florist, on her way home on Sunday. If Perla had $70.75 after her spending, determine her normal hourly rate.

W=normal hourly wage

4W-12.75+5*1.5W-8.50=70.75

4W-12.75+7.5W-8.50=70.75

11.5W-21.25=70.75

11.5W=92

W=8

Normal hourly rate is $8/hour

Check

32-12.75+60-8.50=70.75

Mrac [35]

Answer:

<h3>            a₈₄ = 1655  </h3>

Step-by-step explanation:

15-(-5) = 20 and 35-15=20  so d=20

a_n=a_1+d(n-1)\\\\a_1=-5\\d=20\\\\a_{84}=-5+20(84-1)=-5+20\cdot83=-5+1660=1655

Simplify the following expression.
Alexandra [31]

Answer:

C: 41x + 16.

Step-by-step explanation:

In order to simplify this, you must distribute the negative sign into the 8x+35. You can get rid of the parentheses for 49x+51 since it serves no purpose.

49x+51-8x-35

Combine like terms:

49x-8x+51-35

41x+16

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day.
ozzi

Answer:

The 80% confidence interval for the mean usage of water is between 18.4 and 18.6 gallons per day.

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{1-0.8}{2} = 0.1

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 1-0.1 = 0.90, so z = 1.28

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.

M = 1.28*\frac{2.3}{\sqrt{717}} = 0.1

The lower end of the interval is the sample mean subtracted by M. So it is 18.5 - 0.1 = 18.4 gallons per day.

The upper end of the interval is the sample mean added to M. So it is 18.5 + 0.1 = 18.6 gallons per day.

The 80% confidence interval for the mean usage of water is between 18.4 and 18.6 gallons per day.
