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
Answer:
Limit access to private information by friending someone
Explanation:
When conducting recruitment of an individual employers sometimes do background checks on the person's social media information.
There however needs to be consideration of the person's privacy in doing this.
There should be use of only publicly available information, background check can be done by a third party that is not making hiring decision, and do not request username and password for social media platforms.
It is not best practice to befriend a person on social media in order to obtain their private information.
Answer:
The cost recorded for the equipment=$229,550
Explanation:
The total recorded cost of the automatic equipment has to include the purchase cost and other additional associated costs that come with the equipment. This can be expressed as;
T=P+A
where;
T=total cost
P=purchase cost/invoice cost
A=additional costs(electrical work cost+delivery cost+sales tax+repair cost)
In our case;
T=unknown
P=$190,000
A=(20,000+4,000+13,700+1,850)=$39,550
replacing;
T=190,000+39,550=229,550
The total cost=$229,550
The cost recorded for the equipment=$229,550
