A potter uses three fifths of a pound to make a bowl, how many bowls can a potter make from ten pounds?

mestny [16]

One bowl needs 3/5 of a pound. Knowing that, we just need to find out how many 3/5s may fit in 10:

10 ÷ 3/5 =
= 10 * 5/3 =
= 50/3 =
= 16 2/3

Assuming the potter can't make a 2/3 of a bowl, he'll be able to make 16 bowls from 10 pounds.

The mean of the data is 18. What number is missing? 21,11,_,27,22,13,16

Ludmilka [50]

The missing number is 16

Solution:

Given that mean of data is 18

Let "x" be the missing number

The data set is:

21, 11, x , 27, 22, 13, 16

Sum of data set = 21 + 11 + x + 27 + 22 + 13 + 16

Sum of data set = 110 + x

The mean is given by formula:

$Mean = \frac{\text{sum of all numbers}}{\text{total numbers in data set}}$

Substituting the values we get,

$18 = \frac{110+x}{7}\\\\126 = 110 + x\\\\x = 126 - 110\\\\x = 16$

Thus the missing number is 16
