Answer:
598=194+8x
Step-by-step explanation:
To solve you would subtract 194 from its self and 598
598=194+8x
-194 -194
404=8x
then you would divide 8 from it's self and 404
which would make it 50.5
(but you cant buy half a package of spoons so realistically it'd be 50 or 51.
hope this helped :)
The z score for a confidence level of 99% is 2.575.. You need to know this to complete this type of problem.. the other two commonly used confidence levels are 90% and 95% having z scores of 1.645 and 1.96 respectively. You need to memorize this!
To find the confidence interval, it will be defined as the sample mean plus/minus the margin of error.. Now to find the margin of error, divide the standard deviation of 12 by the square root of the number of elements in your sample(√250). Then take that result and multiply it by the Z score I mentioned above for a 99% confidence level.
In this case: the sample mean is 70 and the margin of error is approximately 1.95
So to calculate the confidence interval, do the following:
70 - 1.95 = 68.05 rounded to the nearest whole number is 68
70 + 1.95 = 71.95 rounded to the nearest whole number is 72
Looks like that would be the last choice. hope this helps.. it's been awhile since my work with statistics :-)

Answer:
<u>Because Nevada is one of the seven states where residents no pay income tax, no matter how much you make. This decision is compensated with a higher-than-average sales tax.</u>
Step-by-step explanation:
1. Let's check the information provided to us to answer the question correctly:
Layla annual earnings = US$ 55,000
A.J. annual earnings = US$ 55,000
Income tax rate paid by Layla = 4.63%
Income tax rate paid by A.J. = 0%
2. Colorado uses these taxes to pay for public services such as school, police, and sanitation. A.J. pays 0 percent of his yearly income to the state of Nevada in income taxes. Yet his town has schools, police, and sanitation services. Why does this happen?
Because Nevada is one of the seven states where residents no pay income tax, no matter how much you make. This decision is compensated with a higher-than-average sales tax.
