Answer:
-3
Step-by-step explanation:
slope formula is y2-y1 over x2-x1
if we plug in the values and solve, that gets you -3.
Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
Chocolatey107 is right!
Mean: 175/5 = 35.
Median: 0, 25, 25, 25, 100 - 25 is in the middle.
Mode: 25, it appears the most.
The outlier 100 affects the data, because the number 100 still farthest from the main cluster. (Sorry if this is wrong)
