Simplified, it is equal to 2x+5.
To get your answer, you factor the numerator. Then, when you get (2x+5)²/(2x+5), you cancel out one of the 2x+5 in the numerator with the one in the denominator and get your answer.

Answer:
The standard error for the sampling distribution is 1.323.
Step-by-step explanation:
Let <em>X</em> = scores of girls and <em>Y</em> = scores of boys.
The information provided is:
As the population standard deviations are not known, use a pooled standard deviation to estimate the standard error of the sampling distribution.
The formula of pooled standard deviation is:
Compute the standard error for the sampling distribution as follows:
Thus, the standard error for the sampling distribution is 1.323.
