Answer:
Step-by-step explanation:
Area = 1/2 × base × height
Base(b) = 7 feet
Height(h) = 12 feet
Area = 1/2 × 7 × 12 = 7 × 6 = 42 feet²
Answer:
similar triangles can be used to find the height of a building.
Step-by-step explanation:
You have that:
- Her contribution from her salary <span>to her 401(k) plan, </span>is: 12%.
- Her annual salary is: $55,700.
Then, to solve this problem and calculate her pretax income, you must following the steps below:
1. You must calculate the amount that Violet contributed to her 401(k) plan. So, you have:
12%/100=0.12
($55,700x0.12)=$6,684
2. Now, you must subtract her annual pay ($55,700) by the amount obtained ($6,684), as below:
Pretax income= $55,700-$6,684
<span> Pretax income=$49,016
</span><span>
What is her pretax income?
The answer is: Her pretax income is </span>$49,016
Answer:
The F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.
Step-by-step explanation:
There are four treatments in the data given, i.e. k = 4.
Total number of observations, n = 12.
Note: degrees of freedom is denoted as df.
For treatment, the degrees of freedom = k-1 = 4-1 =3 df.
The total degrees of freedom = n-1 = 12-1 = 11 df.
The error in degrees of freedom = df (total) - df(treatment)
The error in degrees of freedom = 11 - 3 = 8 df
At α = 0.05 level,from the F table, the F-statistic with (3 , 8)df is 4.07.
Therefore, the F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.
