Find the product of the given polynomials. <br> (5x + 8 – 6r) (4 + 2r – 7)<br><br><br>​
Inessa05 [86]

Answer:

-12r² + 10xr - 15x + 34r - 24

Step-by-step explanation:

1. Organize it, variables first - as well as adding constants such as 4 and -7

(5x - 6r + 8) (2r - 3)

2. Start by multiplying the 5x by (2r - 3), then -6r, followed by 8

(10xr - 15x) + (-12r^2 + 18r) + (16r - 24)

3. Simplify

10xr - 15x - 12r² + 18r + 16r - 24

4. Order by greatest to smallest factorial

-12r² + 10xr - 15x + 18r + 16r - 24

5. Combine like variables

-12r² + 10xr - 15x + 34r - 24

Go step by step to reduce the radical. V108 VOVO try You must answer all questions above in order to submit.
katen-ka-za [31]

To reduce the radical, you have to factorize 108.

108 is a multiple of 3, so to factorize it, you can divide it by 3

\frac{108}{3}=36

You can rewrite the square root as:

\sqrt[]{3\cdot36}=\sqrt[]{3}\cdot\sqrt[]{36}

The square root of 36 is equal to 6 so you can write the expression as:

\sqrt[]{3}\cdot\sqrt[]{36}=6\sqrt[]{3}

A large company releases summary statistics about the annual salaries for its employees. Mean standard deviation minimum Q1 medi
iren2701 [21]

Pieces of data such as $18,000 and $350,000 represent outliers in this chart in standard deviation .

How to interpret a standard deviation?

  • The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
  • The standard deviation calculates how much the data vary from the mean value. It is helpful for contrasting data sets that might have the same mean but a different range.

In this chart, there are outliers. The main outliers are $18,000 and $350,000. This is because we know the mean or average is $63,423, and therefore values that are too different from this average are considered outliers.
