Step-by-step explanation:
Read the answer above/ below mine, I just wanted to point out that to solve this problem you use the circumference formula! The circumference of a circle is 2pi(r). r= radius= 10 (because 10 mi). Plug this into a calculator by typing: (20*pi) [division symbol] 8 =, and then it will give you 7.85..., but remember to round up to 7.9.
A. 30.6%
B. 48.2%
C. 51.8%
D. 69.4%
Answer:
The answer is 48.2%
Step-by-step explanation:
The correlation coefficient r between a child age x and the number of minutes spent doing homework each day y is 0.694 i.e r=0.694
Now, we have to find percent of the variation.
The coefficient of determination is
The square of r(correlation coefficient) is the percent of variation that is explained by the dependent variable.
If r=0.694 ⇒ this means that 48.2% of variation in dependent variable.
