21.19%
First you need to find the z-score with
X- Mean
----------- = Zscore
Standard
Deviation
Then use your z table (should be on your formula sheet if not look one up)
to find your proportion (in this problem it would be .2119) and convert it to a percent.
So plug everything in
6.64-7.2
------------ = Z-Score
.7
Z-Score= 0.8
The table showed our proportion to be .2119
therefore your percent is 21.19%
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set.
Find the sum of the data values, and divide the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
Divide the sum of the absolute values of the differences by the number of data values.
Answer:
h = 1000 / (3.14)(r²)
Step-by-step explanation:
Given in the question,
volume of cylinder = 1000 inches³
Formula to use
V = πr²h
where V = volume
π = 3.14
r = radius
h = height
1000 = (3.14)(r²)(h)
h = 1000 / (3.14)(r²)
