Find the measure of each interior angle of a regular octagon. (A regular polygon is one that has all the same sides and angles).
NemiM [27]

The interior angle of a regular octagon is 135 degrees.

<h3>What is an octagon?</h3>

An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.

Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.

Therefore,

n = number of sides = 8

Hence,

interior angle = (n - 2)180 / n

interior angle = (8 - 2)180 / 8

interior angle = 6 × 180 / 8

interior angle = 1080 / 8 = 135°

A newsletter publisher believes that above 78 % of their readers own a personal computer. Is there sufficient evidence at the 0.
GalinKa [24]

Answer:

h_{0}: p= .78

h_{a}: p > .78

Step-by-step explanation:

Determining the null and alternate hypotheses of a scenario require several components. The first is if one should use p or mu. This depends on if they are assessing a proportion or a mean, since the publisher states a percentage, you know that they are asking for a proportion, and therefore should use p. Next, they will need to assess what value to use for the hypothesis statements, here only .78 is provided and therefore should be used in both. Finally, it is time to add in the comparison symbols, the null hypothesis always uses an equals sign so it therefore becomes:

h_{0}: p= .78

The alternate hypothesis then needs to consider if the researchers claim that the new proportion is greater, fewer, or different. In this case it is greater as they think that the ownership is above 78%, so a greater than sign would be used and the final statement would be:

h_{a}: p > .78

Point E is between points D and F. If DE = x - 4 , EF = 2x + 5 , and DF = 4x- 8 , find x
horsena [70]
You know that 
DE+EF=DF&#10;(x-4) + (2x+5) = (4x-8)&#10;

combine like terms3x+1 = 4x-8&#10;1 = x-8&#10;x=9
