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>.

Answer:
The trigonometric ratio of theta is tangent ⇒ answer (c)
Step-by-step explanation:
* Lets revise the trigonometry functions
- sinФ = the side opposite to angle Ф ÷ the hypotenuse
- cosФ = the side adjacent to angle Ф ÷ the hypotenuse
- tanФ = the side opposite to angle Ф ÷ the side adjacent to angle Ф
* Now read the definition of the slope and look to the figure
- The slope of a line is the ratio of the change of y to the change of x
∵ The change of y is opposite to angle Ф
∵ The change of x is adjacent to angle Ф
∴ The slope = the side opposite to Ф ÷ the side adjacent to Ф
* The slope of the line = tanФ
∴ The trigonometric ratio of theta is tangent
Answer:
Step-by-step explanation:
This question is basically saying: what is half of 7, or what is 7 divided by 2?
Based on this, it can be written both of the ways as:
»» 
of 7 <u>OR</u> 7 ÷ 2
So, just solve using either one and you’ll get 4.5 or . But since the question wants the answer to be a mixed number, then choose .
Hope this helps! :)
3 feet is equal to 1 yard and 3 feet is 36 inches. 288 inches divided by 36 is 8 so 8 yards is equal to 288 inches.
The formula for area is length x width
So there is a rectangle with a length of 5 and a width of 9. To find the area you must multiply 5 and 9, which is 45. That's your area.
Now say you have a triangle. That triangle has a length of 46 and a height of 99. Again, l x w. 46 x 99 =4554.
Any other questions, let me know.
