The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample (
) = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) = 
= 
= 
= 11
Hence the standard deviation is equal to 11.
Answer: D. supervisors gain experience in and are accountable for solving problems in their work units.
Explanation:
A chain of command is necessary in business because it diversifies authority such that decisions can be made faster.
It works by dividing employees into units which will answer to a manager. That manager will make decisions for the unit and this leads to decisions being made faster because everybody wouldn't have to go to upper management when they already have a manager.

Answer:
BUDGET LINE
Explanation:
Budget Line is graphical representation of product combinations that a consumer can buy, given product prices & income (all spent)
It is downward sloping because of inverse relationship between goods - one good's consumption has to be decreased to increase other good's consumption, given same prices & income.
Budget Line Equation : x.px + y.py = m
[x = quantity of good x, px = price of good x, y = y good quantity, py = good y price, m = money income].
Slope of Budget line is : Amount of a good sacrifised to attain the other good, given same prices & income. The sacrifise ratio gets derived from the price ratios of the two goods.
Budget Line Slope = ΔY / ΔX = PX / PY
