<h3>
Answer: A) -0.83</h3>
Without the actual numeric data coordinates, it is impossible to compute the true r value. Though we can estimate. The data points are negatively correlated in a fairly strong manner. We can draw a straight line close to all of these points, so the r value is going to be fairly close to -1. The closer r is to -1, the stronger the negative correlation. Having r = -1 exactly means all of the points fall on some single straight line that slopes downward.
Choice B is the next best choice, but its correlation isn't as strong. So that's why I ruled it out. Choices C and D are ruled out immediately since they are positive values.
First change the percent to a decimal 40% = 0.4
then subtract 99 - 0.4 = 98.6
the answer is 98.6
Answer:
Step-by-step explanation:
Evaluate for x=5,y=−1
−3(5^2)+(2)(5)(−1)−(−1)^3
−3(5^2)+(2)(5)(−1)−(−1)^3
=−84
8yards=24ft
as a fraction=3/24
simplest form=1/8
hope this helps
