Answer:
Step-by-step explanation:
- Height of cone (h) = 7 cm
- Base radius (r) = 3 cm
- Formula for Volume of cone is given as:
- Plugging the values of h and r in the above formula, we find:
Hello!
As we can see, our a value, which would be the coefficient of , which determines our slope, is negative, meaning that this whole line is negative.
Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.
If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.
