Answer:
5 Cars
Step-by-step explanation:
Let the number of cars to be sold to make the total pay equal be x.
The first company pays a salary of $12,500 plus commission of $1500 for each car sold.
- Algebraically written as: 12500+1500x
The second company pays a salary of $17,500 plus a commission of $500 per car sold.
- Algebraically written as: 17500+500x
Equating both sides
12500+1500x=17500+500x
Collect like terms
1500x-500x=17500-12500
1000x=5000
Divide both sides by 1000
x=5
Therefore, when 5 cars are sold, the total pay would be the same.
You can double the product of 9 and 4 to get to the product of 9 and 8
Answer:
The 90% confidence interval for the population mean iron concentration is between 0.167 cc/m³ and 0.195 cc/m³.
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 Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 0.181 - 0.0140 = 0.167 cc/m³.
The upper end of the interval is the sample mean added to M. So it is 0.181 + 0.0140 = 0.195 cc/m³.
The 90% confidence interval for the population mean iron concentration is between 0.167 cc/m³ and 0.195 cc/m³.
