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.
You don't have any choices here, so we can just find the range of the answer. Then, you can select the correct answer.
The probability must be greater than 66.67%: P > 66.67% (or 2/3).
The chance of rain on Friday is 2/3. If it is more likely on Saturday, then it must be more than 2/3. 2/3 is about 66.67% percent.
Answer:
Height= 18cm
Step-by-step explanation:
Curved surface area = 2πrh
108π = 2 * π * 3 * h
108π = 6πh
h= 108π ÷ 6π
h= 18cm
