1. Add the total ages up and divide that by the number of volunteers, that gives you 130 as the total ages added up and 10 volunteers, which gives you a mean of 13,
2. When the numbers are put in an ascending order 12 and 13 appear to be the middle two, therefore divide the sum of the two to find the median, which is 12.5.
Answer: -3
Step-by-step explanation:
They are going by three down and up
More data can be applied to the frequency distribution table. You can measure the "midpoint" (or "class mark") of each class as: Midpoint = Lower class limit + Upper class limit 2 . . The proportion of the data that falls in that class is the "relative frequency" of each class.
Raul has 56 bouncy balls
he puts the balls into red gift bags and green gift bags
so lets say he puts x number of balls into green gift bags
then we are told that he puts three times as many balls into red gift bags as he puts into green gift bags
so the number of balls he puts into red gift bags is - 3 * x = 3x
the total number of balls = 56
so we can write the following equation
x + 3x = 56
4x = 56
x = 56/4
x = 14
therefore the amount of balls he puts into green bags is - 14 balls
