Find the standard deviation for the set of data. (17,26,28,9,30, 29,6,21,23}
1 answer:
Using it's concept, the standard deviation for the given data-set is of 8.22.
<h3>What are the mean and the standard deviation of a data-set?</h3>- The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
- The standard deviation of a data-set is given by the square root of the <u>sum of the differences squared between each observation and the mean, divided by the number of values</u>.
The mean for this problem is:
M = (17 + 26 + 28 + 9 + 30 + 29 + 6 + 21 + 23)/9 = 21
Hence the standard deviation is:

Answer:
Volume of Pipe is 226 ft³.
Step-by-step explanation:
Given:
Cylindrical Shape Pipe having
Height = 18 ft
Diameter = 4 ft
∴
To Find:
Volume of Pipe = ?
Solution:
Formula for Volume of Cylinder is given by
Substituting the given values we get
Volume of Pipe is 226 ft³.
An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one
so
when n=1, an=40
so a1=40
it seems to increas by 7 each time
an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula
the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term
domain is natural numbers
the formula is
