The sampling distribution of x has a mean μₓ = <u> μ </u> and standard deviation σₓ =​ <u> σ/√n </u>.

In the question, we are given that a random sample of size n is drawn from a large population with mean μ and standard deviation σ.

We are asked to find the mean and the standard deviation for the sampling distribution of the variable x for this sample.

The sample mean is regularly distributed, with a mean μₓ = μ and standard deviation σₓ = σ/√n, where n is the sample size, for samples of any size taken from populations that have a normal distribution.

Thus, the sampling distribution of x has a mean μₓ= <u> μ </u> and standard deviation σₓ=​ <u> σ/√n </u>.

zhuklara [117]

Answer:

The answer is 1 13/27.

Step-by-step explanation:

First, convert any mixed numbers to fractions --

the initial equations then reads as 5/3 x 8/9.

Then, applying the fractions formula for multiplication --

5 x 8 / 3 x 9

40/27

Simplifying the above --

1 13/27

Which equation is parallel to the graph of y = 2x-5 and goes through the point (3,9)
Semenov [28]

Answer:

Step-by-step explanation:

y = 2x - 5

Slope of line is 2.

Slope of any parallel to the line is also 2.

You chose y = 3x - 5, which has a slope of 3.

Point-slope equation for line of slope 2 passing through (3,9):

y-9 = 2(x-3)

The answer choices are all in slope-intercept form, so rearrange the equation.

y = 2x - 6 + 9 = 2x + 3

Answer:

j : 7327

Step-by-step explanation:

Split the figure into three parts 1 cylinder and hemispheres.

find the volume of each part and then in the end add them

Vol of cylinder =

\pi \times r {}^{2}  \times h \\ 3.14 \times 10 \times 10 \times 10 \\  = 3140 \\

Find the volume of one hemisphere=

=  \frac{2}{3} \pi \times r {}^{3}  \\ 2093.33

Vol of 2 hemispheres = 2×2093.33

= 4186.66667

Total volume= 3140 + 4186.6667 = 7326.66

= 7327
