6 / 2 = 3
To find the average you need to add the two numbers together and divide by two. 18 + 22 = 40 40 / 2 = 20 The answer is 20.
((1 + 40) x 20)/40 ie 20.5
Average = (9 + 31)/2 = 40/2 = 20
40 ÷ 2 = 20 km/hThe average speed (velocity) is 20 kilometres per hour.
Ca stands for Calcium, 20 is the atomic number, and 40 is the average atomic mass
(20+40)/2=30 kph

When there is an even number of items in the data set the median is the mean average of the middle two. The middle two are the two items themselves, namely 20 and 40, so the median is (20 + 40)/2 = 30.
40 - 20 percent = 820% of 40= 20% * 40= 20%/100% * 40= 8
