Answer:

Polygons are named according to the number of sides and angles they have. The most familiar polygons are the triangle, the rectangle, and the square. A regular polygon is one that has equal sides. Polygons also have diagonals, which are segments that join two vertices and are not sides.

How to do 15 1/2 - 2 1/10 how to do it

lisov135 [29]

First, you need to make the fractions have the same denominator:

15 1/2 ---> 15 + (1/2 x 5) = 15 5/10

2 1/10 ---> 2 1/10

Then you need to subtract them from each other:

15 5/10

<u>- 2 1/10</u> (or) 15 5/10 - 2 1/10 = 13 4/10

13 4/10

This gets the answer: <u>13 4/10</u>

What is the slope of the line that passes through the points (9, -1) and (4, -11)?

mixas84 [53]

Answer:

Step-by-step explanation:

We have two points so we can find the slope

m = ( y2-y1)/(x2-x1)

= ( -11 - -1)/( 4 -9)

= (-11+1)/( 4-9)

-10/ -5

= 2

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

n instances of a normal variable:

For n instances of a normal variable, the mean is $n\mu$ and the standard deviation is $s = \sigma\sqrt{n}$
