Answer:
The percentage of inter-rater reliability is 80%.
Step-by-step explanation:
The rate of inter-rater reliability is the division of the number of intervals in which they agreed number of total intervals.
In this problem, we have that:
There are 10 intervals.
The observers agreed on 8 of them.
So the rate of agreement is 8/10 = 0.8.
As a percentage, we multiply the rate by 100, so 0.8*100 = 80%.
The percentage of inter-rater reliability is 80%.
Answer:
4x + 6
Step-by-step explanation:
Given
+ ![\frac{3}{x+1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%2B1%7D)
Before we can add the fractions we require them to have a common denominator.
Factor the denominator of the first fraction
+ ![\frac{3}{x+1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%2B1%7D)
Multiply the numerator / denominator of the second fraction by (x + 2)
=
+
← fractions now have a common denominator
Add the numerators leaving the denominators
= ![\frac{x+3(x+2)}{(x+1)(x+2)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B3%28x%2B2%29%7D%7B%28x%2B1%29%28x%2B2%29%7D)
= ![\frac{x+3x+6}{(x+1)(x+2)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B3x%2B6%7D%7B%28x%2B1%29%28x%2B2%29%7D)
=
← simplified sum with numerator 4x + 6

Answer:
A. 2y^4 over x^2
Step-by-step explanation:
4x^4y^6 ÷ 7x^8y^2
First, you will find the GCF of the equation which is: 7x^4y^2 .
Then, you will divide both of the equation by the GCF which will become:
14x^4y^6 ÷ 7x^4y^2 = 2y^4
7x^8y^2 ÷ 7x^4y^2 = x^2
Hence, the final answer is 2y^4 over x^2
