Answer:
<em>$570 a week</em>
Step-by-step explanation:
<u>Percentage Calculations
</u>
One tricky fact about percentages is that they are usually performed over the last computed quantity. It makes them non-additive. For example, a raise of 10% followed by a 10% some time later, is NOT a 20% of total raise
The question states Ashely is making $500 a week at her job and that she receives a 20% pay raise. After that raise she will make
![\$500*(1+20/100)=\$500(1.2)=\$600 \text{ a week}](https://tex.z-dn.net/?f=%5C%24500%2A%281%2B20%2F100%29%3D%5C%24500%281.2%29%3D%5C%24600%20%5Ctext%7B%20a%20week%7D)
A year later she takes a 5% pay cut. We must be careful to take that percentage from the last earnings. She now makes
![\$600(1-5/100)=\$600(0.95)=\$570\ a\ week](https://tex.z-dn.net/?f=%5C%24600%281-5%2F100%29%3D%5C%24600%280.95%29%3D%5C%24570%5C%20a%5C%20week)
Answer:
volume= ![1\frac{1}{3} ft^{3}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B3%7D%20ft%5E%7B3%7D)
Step-by-step explanation:
volume=l×w×h/3
L=2 ft, W=1 ft, H=2 ft
volume= 2×1×2/3=4/3 ft^3
so the volume will be ![1\frac{1}{3} ft^{3}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B3%7D%20ft%5E%7B3%7D)

Answer:
A.) No
B.) test statistic = - 3.108
Check explanation
Step-by-step explanation:
H0: m = 105 versus H1: m ≠ 105
Sample size, n = 35, since we have a large sample size, greater than 30.
B.)
xbar = 101.9 ; s = 5.9
Test statistic :
T = (xbar - μ) ÷ (s/√n)
T = (101.9 - 105) / (5.9/√35)
T = - 3.1 / 0.9972820
Test statistic = - 3.11
Pvalue from Tstatistic, df = 34
Pvalue = 0.003772( Pvalue calculator)
Pvalue is the probability of obtaining a value more extreme or exactly that of the test statistic.
At α = 0.01
Pvalue < α ; We fail to reject the Null
Answer:
What?
Step-by-step explanation:
Area is length x width, and perimeter is adding up all the sides together
so if it’s 32 for the perimeter, then the dimensions should be 12 and 4
12x4 is 48
12+12+4+4 is 32
