\text {Laura = }  12 \text { years } 3 \text { months }

\text {Lisa = }  11 \text { years } 7 \text { months }

\text {Deborah = }  11 \dfrac{1}{2}  \text { years } =  11 \text { years } 6 \text { months }

\text {Elizabeth = }  11 \dfrac{1}{3}  \text { years } =  11 \text { years } 4 \text { months }

-----------------------------------------------------
Find Total :
-----------------------------------------------------
\text {Total = } 12 \text { yr } 3 \text { mth } + 11 \text { yr } 7 \text { mth } + 11 \text { yr} 6 \text { mth} +11 \text { yr } 4 \text { mth}

\text {Total = } 45 \text { years } 20 \text { months }

-----------------------------------------------------
Find Average :
-----------------------------------------------------
\text {Average = } (45 \text { years } 20 \text { months }) \div 4

\text {Average = } 560 \text { months } \div 4

\text {Average = } 140 \text { months } \div 4

\text {Average = } 11 \text { years } 8 \text { months }

You go out to eat with your family. The subtotal on your bill is $45.90. You must pay a 8% sales tax AND you would like to leave
Eddi Din [679]

Answer:

The answer is 57.83

Step-by-step explanation:

find 8% of 45.90 and add 18% of 45.90 and add them together.

8%*45.90=3.67

18%*45.90=8.26

Add, 45.90+8.26+3.67

The final price of your meal is 57.83

A local company makes a candy that is supposed to weigh 1.00 ounces. A random sample of 25 pieces of candy produces a mean of 0.
AysviL [449]

Answer:

n=(\frac{2.58(0.004)}{0.001})^2 =106.50 \approx 107

So the answer for this case would be n=107 rounded up to the nearest integer

Step-by-step explanation:

Information given

\bar X= 0.996 the sample mean

s=0.004 the sample deviation

n =25 the sample size

Solution to the problem

The margin of error is given by this formula:

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}    (a)

And on this case we have that ME =0.001 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

n=(\frac{z_{\alpha/2} \sigma}{ME})^2   (b)

We can use as estimator of the real population deviation the sample deviation for this case \hat \sigma = s/ The critical value for 99% of confidence interval is given by z_{\alpha/2}=2.58, replacing into formula (b) we got:

n=(\frac{2.58(0.004)}{0.001})^2 =106.50 \approx 107

So the answer for this case would be n=107 rounded up to the nearest integer
