Mean is an average of everything so add all the numbers up and then divide by how many there are For example (2005) (20+25+20+43+40)/ 5
And median is the number that is in the middle after u arrange all the numbers in numerical order So like (2005) 20 20 25 40 43 and the median would be 25
Just letting you know if you want to understand it but the answer is C 2007 Because the median and mean is 15
The proportion is 1 cup of sugar for 1 dozen cookies (1/1). So if you multiply the denominator by 6 you must multiply the numerator by 6, and 6*1=6. Therefore you need 6 cups of sugar to make 6 dozen cookies.
