What is indicated by a large variance for a sample of difference scores?
Paraphin [41]
Well the variance is how close or far the points are from the mean.. so if it is a large variance then the sample with be very spread out.  If your variance is large then your standard deviation is also large.

Simplify 24x5 y6 . A) 2x2 y3 6x B) 4x2 y3 6x C) 6x2 y3 4x D) 6x2 y3 2x
Cerrena [4.2K]

Answer : A 2x^2y^3\sqrt{6x}

\sqrt{ 24x^5y^6}

Take square root for each term and simplify it

\sqrt{24} *\sqrt{x^5}  *\sqrt{y^6}

\sqrt{24}=\sqrt{4 * 6}  = 2\sqrt{6}

\sqrt{x^5} = x^2\sqrt{x}

\sqrt{y^6} = y^3

so we will get

2\sqrt{6} *  x^2\sqrt{x} * y^3

2x^2y^3\sqrt{6x}

write a simplified polynomial expression in the standard form to represent the area of the rectangle below x-4 5x+2
Ann [662]

The area of the rectangle is 5x^{2} -18x-8

Explanation:

One side of the rectangle is x-4

The another side of the rectangle is 5x+2

The formula to find the area of the rectangle is length × width

Area = length × width

Substituting the values, we have,

\begin{aligned}\text { Area } &=(x-4)(5 x+2) \\&=5 x^{2}+2 x-20 x-8 \\&=5 x^{2}-18 x-8\end{aligned}

Thus, the area of the rectangle is 5x^{2} -18x-8
