Answer:
b. n=5
Step-by-step explanation:
Because 30 divided by 36 = 0.83333
And 180 divided by 6 = 30 so that eliminates a.
Then if you plug in 5 for n 5 divided by 6 = .833333
Therefore the answers match and n = 5
Hope this helps.
The range is [4, infinity], {y|y greater than or equal to 4}
It is equal to 75%
It shows 3 quarters
On a clock, it would show 45 as the minutes
Fractions:
75/100
45/60
6/8
I think The answer is 2920
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:
