Answer:
Explanation:
The comparison of psychological benefits to actual tangible costs depends on the individual in question. If the individual is constantly stressed to the point which the stress is affecting his/her health, work performance, mood, behavior around family, etc. then the tangible costs of going on vacation may be worth it. This is because a vacation would provide a moment of relaxation which would relieve all of that individual's stress and in doing so improve the individual's work performance, health, and overall quality of life. Therefore, the comparison between physical benefits to costs is always going to be a personal opinion.
Answer:
(a) 
(b) 
(c) X=4.975 percent
Explanation:
(a) Find the z-value that corresponds to 5.40 percent
.
Hence the net interest margin of 5.40 percent is 2.5 standard deviation above the mean.
The area to the left of 2.5 from the standard normal distribution table is 0.9938.The probability that a randomly selected U.S. bank will have a net interest margin that exceeds 5.40 percent is 1-0.9938=0.0062
(b) The z-value that corresponds to 4.40 percent is 
The net interest margin of 4.40 percent is 0.5 standard deviation above the mean.
Using the normal distribution table, the area under the curve to the left of 0.5 is 0.6915
Therefore the probability that a randomly selected U.S. bank will have a net interest margin less than 4.40 percent is 0.6915
(c) The z-value that corresponds to 95% which is 1.65
We substitute the 1.65 into the formula and solve for X.
A bank that wants its net interest margin to be less than the net interest margins of 95 percent of all U.S. banks should set its net interest margin to 4.975 percent.
Answer:
$195,488.6
Explanation:
The computation of the amount at the end of the 22 years is shown below
The Amount at the end of 1st 11 years is
= Principal × (1 + interest rate)^number of years
= $19,750 × (1 + 0.09)^11
= $50,963.42
Now the amount at the end of the last 11 years is
= $50,963.42 × (1 + 0.13)^11
= $195,488.6
hence, the value at the end of the 22 years is $195,488.60
Answer:
B. Ladder safety or personal fall arrest systems
Explanation:
Under the provisions of OSHA laws, where the total length of a climb equals or is greater than 24 feet or 7.3 meters, ladders must be equipped with one of the following safety devices.
- ladder safety devices
- Self-retracting lifelines, and rest platforms at intervals not to exceed 150 feet (45.7 m)
- A cage or well and multiple ladder sections with each ladder section not to exceed 50 feet (15.2 m) in length.
The safety devices are cautionary provisions to protect a climber should the unexpected happen.To ascend a height of 24 feet and more is exhausting, which poses a risk. The climber may feel dizzy or develop height phobia due to exhaustion.
