the below shows the distribution of marks obtained by a group of students in a mathematics test The marks are : 5,6,7,8,9,10. And the number of students are : 4,8,10,7,13,3 Calculate the mean, median, mode, range.

Hey there!

We have:

4 students with 5 marks.

8 students with 6 marks.

10 students with 7 marks.

7 students with 8 marks.

13 students with 9 marks.

3 students with 10 marks.

Thus, the mean is: , or around 7.58 marks.

The median is the middle number and since we have 45 people, the middle number would be the 23rd.  4+8+10+1=23, Thus, 8 marks i s the median.

The mode is the most common score, which is 9.

The range is the range of all the values, which is from 5-10. Thus, giving us a range of 10-5, or 5.

Hope this helps :)

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
