Answer:
Standard error
Step-by-step explanation:
The standard deviation of the distribution of sample means is called the standard error of the means.
It is denoted by:
The standard error is calculated using the formula:
where n is the sample size and is the population standard deviation.
Answer:
251.20 cm square
Step-by-step explanation:
As given in figure
height of cylinder = 2 cm
radius of cylinder = 8 cm
lateral surface area of cylinder is given by =
where r is the radius and l is the height
Therefore, lateral surface area of given cylinder
area of base is give by
since there is only one base area of that base
=
Thus,
Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
