Find the median first. The middle of all the numbers.
5, 7, 8, 10, 11, 13, 14, 18, 27
11 is the median.
Then find the median of the upper quartile.
The upper quartile consists of numbers...
5, 7, 8, 10
Since it is an even set of numbers add the two in the middle and divided by two. So 7 plus 8= 15/2.
7.5 is your upper quartile.
A is no observable trend, B is a positive linear trend, C is a negative linear trend, and D is an exponential trend
56 is the right answer trust me
3c(5+c) -2(3c-7)
15c+3c^2-6c+14
9c+3c^2+14
