So since a percent is out of 100 you would put 11/20 and right an equal sign next to that and the bottom fraction would be x/100. Then you would find the relationship between 100 and 20. 20 times 5 is 100 so then 11 times 5 is 55. 55% is your answer
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>

Answer:
y = 1/2x - 2
Step-by-step explanation:
Slope: 1/2
Point: (0, -2)
y-intercept: -2 - (1/2)(0) = -2
An hour is 60 minutes, divide 60 by 20(that equals 3), then multiply 3 by 3 to get the answer 9 pages.
