Answer:
1 hour = $9.2
Step-by-step explanation:
The question says that:
Brody makes $78.20 in 8.5 hours.
So,
8.5 hours = $78.20
We need to find 1 hour pay.
So, divide both sides of the above equation by 8.5
8.5 / 8.5 hours = $78.20 / 8.5
1 hour = $9.2

Answer:
A sample of 18 is required.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of
.
That is z with a pvalue of
, so Z = 1.88.
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
A previous study indicated that the standard deviation was 2.2 days.
This means that 
How large a sample must be selected if the company wants to be 92% confident that the true mean differs from the sample mean by no more than 1 day?
This is n for which M = 1. So



Rounding up:
A sample of 18 is required.
Answer:
<em>a) g(-2) = 0</em>
<em>b) g(-1) =1</em>
<em>c) g(4) = 2</em>
Step-by-step explanation:
Given data



<u><em>Step( i )</em></u>:-

put x = -2

<em>g(-2) = 0</em>
<u><em>Step(ii)</em></u>:-

Put x = -1

<em>g(-1) =1</em>
<u><em>Step(iii)</em></u>:-

<em>g(4) = 2</em>

Answer:
v = 28/29
Step-by-step explanation:
- 9 - (18v - 5) = 2(7v - 16) - 3v
- 9 - 18v + 5 = 14v - 32 - 3v
- 18v - 14v + 3v = - 32 - 5 + 9
- 29v = - 28
v = -28 / -29
v = 28/29
Answer: The total profit is $129
Step-by-step explanation:
The total revenue, was $147 (the total they earned), and the cost of the materials is $18 (how much they returned for the materials)
The total profit is computed as the difference between the revenue and the costs, then the total profit of the kids in this case is:
Profit = $147 - $18 = $129
This means that Tia and Jaden earned $129, if they divide it evenly, each one of them gets $129/2 = $64.5
