To find the median you list out all the numbers and find the middle.
80, 90, 100
With angie getting 75, it goes from "80, 90, 100" to "75, 80, 90, 100"
This changes the median from 90 to 85.
Mean is the average of all the numbers. The average of the first set of numbers (Found by adding all of the numbers up and dividing by the amount of numbers present) is 90.
The mean of the second set is 86.25
The answer would be A, both the mean and median will decrease.
Answer:
y=-1/2*+5
Step-by-step explanation:
Answer:
m(C)<m(B)<m(A).
Step-by-step explanation:
1) according to the condition the shortest side is AB, the longest side is BC, the middle is AC. Then
2) the smallest angle is BCA (or C), the middle angle is ABC (or B), the largest angle is BAC (or A).
-5.1=1.3+w/4
Subtract 1.3 from both sides
-6.4=w/4
Multiply both sides by 4
-25.6=w
Check work:
-5.1=1.3+(-25.6/4)
-5.1=1.3+(-6.4)
-5.1=1.3-6.4
-5.1=-5.1
Hope this helps! :)
