Question

If 11, 13, 15, 18, x + 1, x + 3, 30, 32, 33, 40 have median 24, find the value of x and mean

Answer 1

Answer:

Step-by-step explanation:

11, 13, 15, 18, x + 1, x + 3, 30, 32, 33, 40

No of elements =10

Thus median is  average of 10/2th and 10/2 +1 the term

=1/2( 5th term +6th term)

=(x+1+x+3)/2=24

2x+4=2*24=48

2x=48-4=44

x=21

Now sum of all terms =(11+13+15+18+(21+1)+(21+3) +30+32+33+40)

=238

Thus mean=238/10=23.8

Answer 2

Answer:

X = 21

mean 238 / 10 = 23.8
