Answer:
The equation for the area of a circle is A = πr².
If you double the radius, the area increases exponentially by a factor of two. The area will be squared.
Isolate y: 2x-15(20+x)=-1
isolate x: 20-23 = -3
substitute: x = -23
answer: (-23, -3)
We know that
In statistics, the correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot. The value of r is always between +1 and –1
using a excel tool
see the attached figure
<span>the r-value is -0.98534-------> -0.985
</span>
the answer is-0.985
