To determine the standard deviation of the number of people who suffer from insomnia, you need to use the following formula:
= sqr of npq
= √10,200 people in the community x 0.6 people who suffer from insomnia x 0.91 = ?
= √10,200 x 0.6 x 0.91 = <span>√55.143 = 7.43
= 7.43</span>

Answer:
mc=mr
Explanation:
This is because in economics, the profit maximization rule is represented as MC = MR, where MC stands for marginal costs, and MR stands for marginal revenue. Companies are best able to maximize their profits when marginal costs -- the change in costs caused by making a new item are equal to marginal revenues............................
Answer:
Simple rate of return = 6.25%
Explanation:
As per the data given in the question,
Net operating income = saving - depreciation on machine
Investment = cost price - scrap value
So, we can calculate the simple rate of return by using following formula:
Simple rate of return = Net operating income ÷ investment
By putting the value, we get
= ($138,000 - $89,200) ÷ ($802,800 - $22,200)
= 0.0625
= 6.25%
Answer:
40%
Explanation:
The computation of the return on equity is shown below:
= (Net income - interest expense) ÷ (weightage average of common stockholders' equity)
where,
Weightage average of common stockholders' equity equals to
= (Total common stockholders' equity at the beginning of the year + Total common stockholders' equity at the end of the year) ÷ 2
= ($410,000 + $290,000) ÷ 2
= $350,000
And, the other items values would remain the same
Now put these values to the above formula
So, the value would be equal to
= ($170,000 - $30,000) ÷ ($350,000)
= 40%
