I assume that 196 is the volume of the prism.
After scaling up the volume will be 196 * 10^3 = 196,000 cubic units.
I drew it pictorially but think of it as 5 sandwiches divided by 3 sisters. Therefore it’s 5/3
Answer:
a. The value depreciation for the first year is $28000.
b. There will be a loss of sale of the equipment by $6000.
Step-by-step explanation:
Equipment was purchased at the beginning at a cost of $465,000.
Now, the price of the equipment depreciates in a linear manner i.e. depreciates equally every year.
The price of the equipment is depreciated to $45000 after 15 years of its estimated useful life.
So, the per year depreciation of value of the equipment will be dollars per year.
a. The value depreciation for the first year is $28000. (Answer)
b. The depreciated value of the equipment after 8 years will be $[465000 - (28000 × 8)] = $241000.
If the equipment was sold for $235000 at the end of the eighth year, then there will be a loss by $(241000 - 235000) = $6000. (Answer)
Answer:
The confidence interval for the mean is given by the following formula:
(1)
Or equivalently:
For this case we have the interval given (3.9, 7.7) and we want to find the margin of error. Using the property of symmetry for a confidence interval we can estimate the margin of error with this formula:
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
represent the sample mean for the sample
population mean (variable of interest)
