Answer:

Variance = 0.02141851

Explanation:

We first calculate the mean for the stocks

Mean = (0.1858 - 0.0558 + 0.2081) / 3

Mean = 0.3381 / 3

Mean = 0.1127

Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1

Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2

Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2

Variance = 0.04283702 / 2

Variance = 0.02141851

The variance of returns is 0.02141851

creativ13 [48]
<span>First we must determine the cost of goods sold during November. For this we use beginning inventory ($368,000) + purchases ($217,500) - ending inventory ($226,750). This gives us a total cost of goods sold for November of $358,750. Then, we take the net sales ($1,000,000) minus the cost of goods sold ($358,750) which equals our gross profit of $641,250. Finally we divide gross profit ($641,250) by net sales ($1,000,000) to determine the gross profit rate to be 64.125%</span>

scZoUnD [109]

Answer:

Amount after 15 years = 183255.011

Explanation:

Below is the calculation to find the amount after 15 years:

Annuity amount or early deposited amount = $5200

Time period = 15 years

Interest rate = 11.3 %

Now we have to find the amount after 15 years:

Amount after 15 years = Annuity [((1 + r)^n - 1) / r ]

Amount after 15 years = 5200 [((1 + 11.3)^15 - 1) / 11.3% ]

Amount after 15 years = 183255.011
