Answer:
x = 8
Step-by-step explanation:
4x - 32 = 0
4x = 0 + 32
4x = 32
x = 32/4
x = 8
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:
5397.76 m^2
Step-by-step explanation:
We have a rectangle in the middle
The area is
A = l*w
A = 44*88 = 3872
We have 2 semicircles on the ends, which is one circle
the diameter is 44 which means the radius is 44/2 = 22
A = pi r^2
A = 3.14 ( 22)^2
A = 3.14 (484)
A =1519.76
Add the two areas together
A =1519.76+3872=5391.76
