Answer:
2)
3) 5√2
Step-by-step explanation:
Simplest radical form of an expression is the expression in radical so that there are no more square roots, cube roots, 4th roots, etc left to find, after rationalising the denominator ( if needed ).
2. Here the given expressions,
For rationalising the denominator multiply both numerator and denominator by √11,
3. given expression,
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>
