Step-by-step explanation:
<u>Step 1: Define</u>
2/3(6h - 9) = 6
<u>Step 2: Solve for </u><em><u>h</u></em>
- [Division Property of Equality] Divide 2/3 on both sides: 6h - 9 = 9
- [Addition Property of Equality] Add 9 on both sides: 6h = 18
- [Division Property of Equality] Divide 6 on both sides: h = 3
The example that I can think of is a deck of playing cards. The two events that don't have a common set would be the black card and the red card. They are mutually exclusive because there can only be two possible colors. If the card is not red, then it is black (and vice versa). There is no card that consists of both colors.

Answer:
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
Find the margin of error for the confidence interval for the population mean with a 98% confidence level.
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
