Answer:
y = 45
Explanation:
(8)(10)(2)y = 7200
[ Simplify both sides of the equation ]
160y = 7200
[ Divide both sides by 160 ]
160y / 160 = 7200 / 160
y = 45
Check:
8(10)2(45) = 7200

Answer:
Average salary: 56
Standard deviation of the salary: 8
Step-by-step explanation:
$56,000 dollars is 56 thousand dollars.
$8,000 is 8 thousand dollars.
The mean is the average. So the average, measured in thousands of dollars, is 56.
The standard deviation is $8,000. So, the standard deviation measured in thousands of dollars, is 8.
Standard deviations, σ, is generally preferred over range. Reason being, it is calculated from all the data and when there is outliers it will not be impacted as much as the range. It is great to not also that, The IQR is preferred to the standard deviation when the distribution is very highly skewed or when there are severe outliers, because the IQR is less sensitive to this features than standard deviation.
