Answer:
The equation is 4x + 5 = 2x + 6
Step-by-step explanation:
The solution is 
means x =
Let us put the coefficient of x in the left hand side = 4 and the coefficient of x in the right hand side = 2
∵ 4x - 2x = 2x
Now we need two numerical terms their difference is 1 like 5 and 6 or 6 and 7 or 7 and 8 or 8 and 9
Let us take 5 and 6
∵ 4x + 5 = 2x + 6
- Subtract 2x from both sides
∴ 2x + 5 = 6
- Subtract 5 from both sides
∴ 2x = 1
- Divide both sides by 2
∴ x =
∴ The solution is
The equation is 4x + 5 = 2x + 6
The value of r indicates the negative correlation.
<h2>Given </h2>
Rikki decided to collect data to determine if a runner's time and speed are correlated.
She determined the data to have a correlation coefficient of -0. 5.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of the two variables.
She determined the data to have a correlation coefficient of -0. 5.
Here, the coefficient is negative which is -0.5.
This correlation coefficient indicates that there exists a weak negative correlation between the runner’s time and the speed.
This relation is negative because the correlation coefficient is negative.
Hence, The value of r indicates the negative correlation.
