For every group of 5 paintings, he makes one sculpture
So if there are 10 groups of five paintings, he made 10 sculptures.

= 
= 
( multiply both sides by 90 )
90 × sin44° = JK , that is
JK ≈ 63 ( to the nearest whole number )

How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Median
Arrange your numbers in numerical order.
Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
