Answer: x is 20
Because both angles together make up 180° you can simply rearrange the equation to get 8x+20=180 and by solving you can come to the conclusion x=20
Answer:
The correct option is C) r=-0.80
Step-by-step explanation:
Consider the provided information.
Properties of r in a scatter plot:
The value of r is between -1 and +1.
If the value of r is positive then it associated with positive relationship if the value of r is negative it associated with negative value.
The greater value of r would be closely around a straight line(Regardless of sign).
Now consider the provided relation.
The use of regression line is to minimize the distance between projections and real values.
Correlation is inversely proportional to difference between predicted values and actual values.
So for good fit we just need to look for the highest value of r regardless of the sign.
From the provided options the highest value of r=-0.80
Thus, the correct option is C) r=-0.80
I am going to assume 2.5x is really 25x (typo).
First formulate the equality
Now two results emerge.

The fraction equivalent to 24 /56 is 6/14.
<h3>What is fraction?</h3>
A fraction having whole numbers for the numerator and denominator. A fraction is a number of the form: ab where a and b are integers and b≠0. It represents the division of two numbers.
Given:
Scale the numerator and the denominator down by a factor of 4.
According to given question we have
Down by a factor of 4 means divide by 4.
when you scale the numerator and denominator down by 4, you just divide both of them by 4.
So since 24 divided by 4 is 6 and 56 divided by 4 is 14,
The answer is 6/14.
Therefore, the fraction equivalent to 24 /56 is 6/14.
