Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5, hence
sum = 180° × 3 = 540°
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:
94 yd i got 100% on my test
Step-by-step explanation:
The longest side = x
the second side is half the longest side = (1/2)x
the third side is 12 feet less than the longest side = x-12
The perimeter (the sum of all sides) is 53.
The lengths of the sides are 13, 14 and 26 feet.
Well since it’s a open circle it’s between B and C. But I’ll choose B. Hope this helps.
