Question

The list of numbers 41, 35, 30, X, Y, 15 has a median of 25. The mode of the list of numbers is 15. To the nearest whole number, what is the mean of the list?

A.20
B.25
C.26
D.27
E.30​

Answer 1

Answer: D.27

Explanation:

you have to plug in the 25 and 15 then find the mean which would be 26.8 which would round to 27

Answer 2

C) 26

Explanation:

41 , 35,30 , X , Y ,15

Number of data's = 6. So, median will be the average of
`((6)/(2))^(th) \ and \ ((6)/(2)+1)^(th) \ term` . 3 and 4th term

Median =
`(30+X)/(2)`

`(30+X)/(2)=25\\\\`

30 + X = 25*2

30 + X = 50

X = 50 - 30

X = 20

Mode is 15

So, Y = 15

41,35,30,20,15,15

`Mean =(41+35+30+20+15+15)/(6)= (156)/(6)=26`
