4/x = x/64x2 = 256x = 164/16 = 16/64 = 1/4
If you mean 4/16, the answer is 1/4. or 25%
Mean = (15 + 12 + 16 + 13)/4 = 56/4 = 14
If you mean the square root of (4 x 16) the answer is 8 or -8. If you mean (the square root of 4) x 16, the answer is 32 or -32.
four and sixteen16 - 4 = 1216 + 4 = 20 then 20 / 2 = 10Half of 12 is 6, therefore the two numbers 10 - 6 = 4 and 10 + 6 = 16 will have a mean of 10 and a range of 12.Further numbers can be added between 4 and 16 as long as their mean is still 10, eg the data sets:{4, 16}{4, 10, 16}{4, 8, 12, 16}{4, 8, 10, 12, 16}{4, 7, 9, 14, 16}all have a mean of 10 and a range of 12. There is an infinity of such sets.
