You have to move the -2/5 by the 11j to get k by its self
K=11j+-2/5
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).
79-74 = 5. So the mean has increased by 5 points. (C)
Answer:
LQ = 54
Median = 69
UQ = 94
Step-by-step explanation:
This list is already sorted for you, so you don't need to worry about that, otherwise you would need to sort the numbers in ascending order. To find the median, we do
, where n is the amount of numbers. This gives us 4, so the median is at position 4, so the median is 69. The lower quartile is simply
, so 2, so the lower quartile is 54. The upper quartile is
, so 6, so the upper quartile is 94.
Answer:
y = -3/4 + 4
Step-by-step explanation:
use rise over run to find slope
