Question

If the mode of the data 3,4,5,6,7,5,9,2,3,2,3,7,9,x, 5,3,2,2,3,5 is 3 , then find the value of x

Answer 1

Step-by-step explanation:

1. this question is wrong mode will be midden

Answer 2

Value of x = 40

◆We know

MODE = 3 MEDIAN - 2 MODE

◆Given , Mode = 3

◆Median =( 2+3)/2 = 2.5

Median of an even set the average of two numbers in the middle of set.

◆Mean = (Sum of all numbers in set) ÷ Number of elements

Mean =( 85+x)/20

◆Substitute in the equation ,

Mode = 3Median - 2 Mean

3 = 3× 2.5 - [2× (85+x)/20]

3 -7.5 =( 85+x)/10

-45 = - 85 -x

45 - 85 =- x

x = 40
