The mean of a set of five whole numbers is the same as the median which is equal to the mode which is equal to the range which equals 4 what is the value of the smallest number.
a: 1
b: 2
c: 3
d: 4
e: 6

The mean is the average basically
(summ of all numbers) divided by (total number of numbers) exg
1,2,3
(1+2+3)/(3)=2

median is the number in the direct center when the numbers are aranged in decending or acending order exg
1,2,3
median=2

mode=most common number exg
1,2,3,4,4,4,5,6
mode=4

mean of 5 numbers
(x+y+z+t+a)/5
is the same as
=
the median

which is equal to the range which equals 4
therefor

median=4 and mean =4 so
(x+y+4+t+a)/5=4
multiply both sides by 5
x+y+4+t+a=20
subtract 4 from both sides
x+y+t+a=16

the most common number is 4
so we can assume that the smallest and largest are the same:4

the answer is D:4
