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.

Answer:
Step-by-step explanation:
- A = 1/2(b₁ + b₂)h
- A = 1/2(8 + 4)*6 = 36 m²
Good evening.
This is a
incomplete quadratic equation, because it does not have the term
bx. Therefore, we can solve this faster with the following strategy:

Add
16 to both sides:

Take the square root:

Therefore:
Option 1:
is the correct answer
Step-by-step explanation:
We can put the values of x in each option one by one and then compare the output to find the best option
So,
<u>For y = 5x+5:</u>
Putting x=1,2,3,4,5...

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5
Hence,
Option 1:
is the correct answer
