Step-by-step explanation:
a) The volume of a rectangular prism can be calculated by multiplying its dimensions.
In this case, you know the rectangular solid has 21 feet long, 14 feet wide, and 9 inches deep.
Since , then its depth in feet is:
Therefore, its volume is:
b) Knowing that each cubic foot of mulch costs $11, you can calculate the total cost of the mulch the contractor needs to buy, multiplying the volume by the $11.
Then, you get:
Turn the mixed numbers into improper fractions:
-5 5/8 = - 45/8
-4 7/12 = - 55/12
Remember, when you divide by a fraction, you take its reciprocal and multiply it:
(-48/8) / (-55/12) = (-48/8) x (-12/55)
Simplify the fraction:
72/55
I think this is the answer.
Answer:
Mean = 0.2(100) = 20
Variance = 0.2×0.8×100 = 16
Standard deviation = 4
Yes, np > 5 & nq > 5
Hi there!
First we need to find how many women are working for the company. We can do this by using proportions. Make the ratio of men to women, 3/5, equal 48/w, where w is the number of the women working for the company.
Cross multiply.
3w = 240
Divide both sides by 3.
w = 80
There are 80 women employees.
Now add the number of male and female employees together.
48 men + 80 women = 128 employees
There are 128 employees working for the company.
Hope this helps!
