Answer:
If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:
midpoint=(x1+x22,y1+y22)
Step-by-step explanation:
Answer:
The approximate value of machine after 3 years = $12283
Step-by-step explanation:
Original cost of the copy machine = $20,000
Rate of depreciation each year = 15%
To, find cost of machine after 3 years.
Solution:
The depreciation equation can be given by:
where:
Final value
Original value
rate od depreciation in decimal form
time
Given values:
Using the values to find the value of machine after 3 years.
Thus, approximate value of machine after 3 years = $12283
M is located in Quadrant II, the line BD has a midpoint located in Quadrant II, AD has a midpoint at the origin.
Q=2 would be your answer, just plug the things into the equation
Answer:
Mean $1060
Standard error $34.69
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean $1,060 and standard deviation $190.
Sampling distriution of samples of size 30:
Mean $1060
Standard deviation
