What is the factored form of 6x2 + 11x – 10?

iren2701 [21]

The correct factorization is (3x - 2)(2x + 5).

In order to find this, we first have to set up parenthesis with the front being factors of 6x^2.

(3x ____)(2x _____)

Now we are going to try the factors of the last numbers in the end of these parenthesis. We can try these in different orders and then multiply to determine if we have the correct order. If for some reason we try them all and do not get the appropriate equation, we can try 6x and x as factors instead. However, we'll try -2 and 5 to see the correct result.

(3x - 2)(2x + 5)

6x^2 -4x + 15x - 10

6x^2 + 11x - 10 ---> this is the original. And therefore, it is the right factorization.

A data set has a mean of 150 and standard deviation of 13. The unusual values are those that are less than

zhuklara [117]

Using z-scores, it is found that the unusual values are those that are less than 124.

---------------------------

The z-score of a measure X in a data-set with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations X is from the mean.
Measures that are more than 2 standard deviations from the mean are unusual.
Z < -2 means that the measure X is unusually low.
Z > 2 means that the measure X is unusually high.
