A. never

because you are limiting x from 0 to infinite, and all of these are positive.

Answer:

$7x^{2} y-2xy^2+xy$

Three terms.

Two terms are positive.

Step-by-step explanation:

$8x^2y + 3xy^2 - 2xy - x^2y + 3xy - 5xy^2$

Group like terms

$=8x^{2} y-x^{2} y+3xy^2-5xy^2-2xy+3xy$

Add similar elements: $8x^{2} y-x^2y=7x^2y$

$=7x^2y+3xy^2-5xy^2-2xy+3xy$

Add similar elements: $3xy^2-5xy^2=-2xy^2$

$=7x^{2} y-2xy^2-2xy+3xy$

Add similar elements: $-2xy+3xy=xy$

$=7x^2y-2xy^2+xy$

$7x^2y$ and $-2xy^2$ and $xy$ are the three different terms.

Only $7x^2y$ and $xy$ are positive terms, thus making two positive terms.

Given a normally distributed data set with the mean = 88 and the standard deviation = 6, according to the empirical rule, what p

vladimir2022 [97]

According to the empirical rule, the percent of the data points that are above 76 is; 2.28%

<h3>How to use Empirical Rule in Statistics?</h3>

We are given;

Mean; μ = 88

Standard deviation; σ = 6

Sample mean; x' = 76

Formula for z-score is;

z = (x' - μ)/σ

z = (76 - 88)/6

z = -2

Now, from the empirical rule of normal distribution graph attached, we see that at z = -2, the percentage is 95.44%. However, we want to find the percentage that lie above 27. Thus, this is (100% - 95.44%)/2 = 2.28%
