Answer:
24/7
Step-by-step explanation:
cos(theta)=24/25
so draw right triangle
you get the length of each side be
7 24 25
(you must draw a picture)
then the answer would be 24/7
Answer:
c=45
Step-by-step explanation:
by the pythagorean theorem, c = sqrt(3^2+6^2) = sqrt(9+36) = sqrt(45)
Therefore, c=45.
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.
