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 :)

THE SATELLITES OF URANUS!!

Explanation:

The other answer was WRONG! One of the satellites of Pluto has an orbit like the satellites of Uranus.

Here is a quote from my textbook:

Therefore, the moon remains over one side of Pluto all the time and can never be seen from the other side of Pluto. Like the satellites of Uranus, Charon's orbit is perpendicular to Pluto's orbital plane.
