Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13
For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.
The answer should be 50% because there is two points on each side of the whisker plot making it 50/50
.00008 would be the answer. You would have to move the place the decimal to get this answer. Hope it helps
Answer:
Step-by-step explanation:
6(8-x)(x+4)=0
(48 -6x )(x+4) = 0
48x +192 -6x^2 -24x = 0
6x^2 -24x -192=0
using quadratic formula:
a= 6 b= -24 c= -192
we have:
