Answer:
a
Step-by-step explanation:
a)
(b)
(c)
Step-by-step explanation:
we are given
length is x+1
width is x+3
height is x-3
(a)
we can use volume formula
now, we can plug it
now, we can simplify it
(b)
we are given volume =1001
so, we can set V=1001
and then we can solve for x
now, we can factor it
(b)
we are given volume
so, we can set
and then we can solve for x
now, we can factor it
Answer:
Leanne's hourly rate is $15 per hour
Step-by-step explanation:
Assuming a year is 52 weeks, divide $15,600/52 to find the $/week ($300). Then, divide $300/20 to find the $/hrs ($15)
We can use the sine function and tangent function in order to solve for x and y:

Cohen's d is calculated according to the formula:
d = (mean difference) / standard deviation
0.5 = mean difference / 12
Therefore, mean difference = 6
Since we have a population mean of 80, the sample mean must be 80 + 6 = 86.
