Answer:
$497.80
Step-by-step explanation:
First, you want to find half of 10.48. This should be 5.24.
So, add 10.48 and 5.24. This gives you 15.72.
Now, you want to multiply that by 5, since 5 hours were overtime.
This gives you 78.60.
Lastly, you want to multiply 10.48 by 40.
This gives you 419.20
Now, add 78.60 and 419.20 together, giving you your answer of $497.80
Sara got $497.80 for the week.
Answer:
And
The difference is that MSA takes incount the variation between the groups and the grand mean, and the MSW takes in count the variation within groups respect to the mean of each group
.
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have groups and on each group from we have individuals on each group we can define the following formulas of variation:
And we have this property
The degrees of freedom for the numerator on this case is given by where k represent the number of groups.
The degrees of freedom for the denominator on this case is given by .
And the total degrees of freedom would be
We can find the
And
The difference is that MSA takes incount the variation between the groups and the grand mean, and the MSW takes in count the variation within groups respect to the mean of each group
.
And the we can find the F statistic
Since she already had an integer you do (-9)-10=-19 Then you would do (-19)-8=-27 Then you do -27 + 14=-13 Then -13 + 12=-1 or you can just do -27 + 14 + 12=-1. That's the answer
Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X
