Answer:
Median = 70
Range = 10
Step-by-step explanation:
The median of a set of data is the middlemost number in the set. The median is also the number that is halfway into the set.
72, 77, 77, 77, 70, 75, 70, 67, 76, 73
There are ten numbers, so you solve the equation:
10 ÷ 2 = 5
The fifth number is 70
The range of a set of data is the difference between the highest and lowest values in the set.
72, 77, 77, 77, 70, 75, 70, 67, 76, 73
The greatest number is: 77
The lowest number is: 67
So you find the difference between them:
77 - 67 = 10

When the ball hits the ground, its height (h) will be 0. You can therefore set up the following equation:
Factor:
Since the time must be positive, it hits the ground after 2 seconds. Hope this helps!
This is an example of an arithmetic sequence.
On level one: a 1 = 13.On level twelve: a 12 = 123.The sum of all 12 levels:S n = n/2 * ( a 1 + a n )S 12 = 12/2 * ( a 1 + a 12 )S 12 = 6 * ( 13 + 123 )S 12 = 6 * 136S 12 = 816Answer: I will have 816 gems matched.
