Answer:

Step-by-step explanation:
The formula of a volume of a cone:

r - radius
H - height
We have
r = (7 : 2) in = 3.5 in
H = 4 in
Substitute:


Answer:
B.
Step-by-step explanation:

x is equal to 5 and y is equal to 29
The coding of the statistic is used to make it easier to work with the large sunshine data set
- The mean of the sunshine is 3.05

- The standard deviation is approximately <u>18.184</u>
<u />
Reason:
The given parameters are;
The sample size, n = 3.
∑x = 947
Sample corrected sum of squares, Sₓₓ = 33,065.37
The mean and standard deviation = Required
Solution:

The mean of the daily total sunshine is therefore;



- The mean ≈ 3.05

Alternatively
,
The mean of the daily total sunshine,
≈3.05

Therefore;

Therefore;
The standard deviation,
≈ <u>18.184</u>
