If you would like to find the difference (6y^3 + 17y - 3) - (4y^3 - 11y + 9), you can do this using the following steps:
(6y^3 + 17y - 3) - (4y^3 - 11y + 9) = 6y^3 + 17y - 3 - 4y^3 + 11y - 9 = 2y^3 + 28y - 12
The correct result would be 2y^3 + 28y - 12.

Step-by-step explanation:
The rules of exponents say ...
![\displaystyle\sqrt[a]{b^c}=b^{\frac{c}{a}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csqrt%5Ba%5D%7Bb%5Ec%7D%3Db%5E%7B%5Cfrac%7Bc%7D%7Ba%7D%7D)
Here, you have a=3, b=8, c=x, so the alternate form is ...

Step-by-step explanation:
Use Pyth Theorem
10^2 + 15^2 = c^2
100 + 225 = c^2
325 = c^2
18.027 = c

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.
