Answer: 18
Step-by-step explanation:
- The<u> sample mean</u> is the best point estimate of the population mean .
Given : A simple random sample of 5 observations from a population containing 400 elements was taken, and the following values were obtained (12 18 19 20 21).
Then , the sample mean = 
sample mean 
Hence, A point estimate of the mean is 18.
The answer is 3...........
Step-by-step explanation:
that is totally easy.
in the slope intercept form of a line equation the factor of x is always the slope.
in general
y = ax + b
a = the slope.
so, in our case here
y = 5x - 7
5 is the slope.
and -7 is the y intercept (at what point does the line intercept the y-axis; that is the y value when x = 0).
The answer would be A 20c/d
The total weekly pay of the company is $754.98
What is total hours worked for the week?
The overtime is the excess of total hours, which is 47 hours, over the regular hours of 40 hours of work a week, in essence, overtime hours is 7(47-40)
Overtime rate=regular hour pay*1.5
regular hour pay=$14.95
overtime rate=$14.95*1.5
overtime rate=$22.425
overtime pay for 7 hours=7*$22.425
overtime pay for 7 hours=$156.98
The regular pay is 40 hours of regular time multiplied regular pay per hour
regular pay=$14.95*40
regular pay=$598.00
total pay=regular pay+overtime
total pay=$598.00+$156.98
total pay=$754.98
