Answer:
Sophia gets 7,150
Step-by-step explanation:
Answer:
The expected earnings of the attendant for this particular period are: $12.66
Step-by-step explanation:
We have to calculate expected mean here:
So,
E(x) = ∑x*f(x)
Therefore, the expected earnings of the attendant for this particular period are: $12.66 ..
About 6 cars because 6 times 7 is 42 and if you add that to 25 you get 67 dollars.
This is called a literal equation, or an equation with multiple variables. You solve it the same as you solve any other equation, but the variables stay there the whole time.
If they want "r" to be the subject, then they want you to solve for r. This means that you need to get the variable r by itself on one side of the equation, but still have the equation be equivalent to it original form.
I'm going to show you, in steps, how to solve this problem:
<span>V=πr²h
Divide both sides by "</span>π²h<span>"
</span>V/π²h=(πr²h)/<span>π²h
</span>
V/(π²h)=r
Your answer is r=V/<span>π²h</span>
1.) v=(l)(w)(h)
V=(9)(9)(9)
V=(81)(9)
V=729in^3
2.) (I forget if this is the real equation to this but this would give you the same answer)
V=(l)(w)(h)

V=(8)(6)(12)

V=576/2
V=288cm^3
