Answer 1

Hi ,

Question :

Does the mode change .If another

observation is added to the data in

the existing data ?

Ans : It depends on the observations

given in the problem .

example :

1 ) find the mode of given data

6 , 5 , 10 , 9 , 6 , 12 , 3 , 11 , 10 , 6

Sol : Let us arrange the data in

order

3 , 5 , 6 , 6 ,6 , 9 , 10 , 10 ,11 , 12

6 is repeated more times

mode = 6

a ) If we add the observation 10 ,

mode = 6 , 10

If we add other than 10 , there is no

change in mode


I hope this helps you.

Answer 2

Answer:

Step-by-step explanation:Let the lengths and breadth of rectangle be l & b respectively.

Now l = b+5, perimeter = 2(l+b) = 58 cm

2(b +b +5) = 58

2b + 5 = 29

2b = 24

b = 12 and length = b +5 = 17
