Prepare grouped frequency distribution table
1 answer:
The frequency distribution gives a tabulated representation of the frequency of data values within defined intervals.
Given the scores :
8, 47, 22, 31, 17, 1,38 ,26 ,3 ,34,29,11,27,7,15,24,38,31,21,35,42,42,24,45,23,21,27,29,49,25,48,21,15,18,27,19,45,14,34,37,34
Using a class interval value of 10 :
Class Interval _____ Frequency
0 - 10 ____________ 4
11 - 20 ____________7
21 - 30____________14
31 - 40 ____________9
41 - 50 ____________7
- Histogram of the distribution is attached below.
Therefore, the histogram gives a graphical representation of the frequency distribution table.

To solve this, we are going to multiply our degrees by a conversion factor. Remember that 1°=
, so to convert -40° to radians, we are going to multiply -40° by the conversion factor ; that way we can cancel degrees and express our answer in radians:
(-40°)
We can conclude that the correct answer is: <span>B). -2π/9</span>
(-40°)
We can conclude that the correct answer is: <span>B). -2π/9</span>
