Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640
1st group it’s obvious the numbers go from small to big
Given:
The statements and reasons to solve an equation.
To find:
The missing reason.
Solution:
If a, b and c are three real number, then
Associative property of addition : 
Commutative property of addition : 
Multiplicative property of equality : 
Distributive property of multiplication over addition : 
In the given step, 
is written as 
.
It means, only parenthesis are changed, which is possible by Associative property of addition.
So, the missing reason is Associative property of addition.
Therefore, the correct option is A.
Answer:
The correct option is C) large sample size (n) with small variance.
Step-by-step explanation:
Consider the provided information.
It is given that the other factors are held constant, and we want the narrowest confidence interval for a population mean.
Confidence interval for a population mean is directly proportional to variance and inversely proportional to the sample size.
If we increase the variance, CI will increase. But we want the narrowest CI, so variance should be small.
As CI is inversely proportional to sample size, therefore if we increase the sample size CI will decrease.
Hence, the correct option is C) large sample size (n) with small variance.
