Mean is the same as the average
median is the middle number
mode is the number that is used most often
range is the highest number minus the lowest number
example :
2,3,3,5,7
u find the mean by adding up all the numbers, then dividing by how many numbers there are. (2 + 3 + 3 + 5 + 7) / 5 = 20/5 = 4 (the mean)
the median would be the middle number, and that would be 3
the mode would be the number that appears the most..that would be 3 because it appears twice.
the range is the highest - lowest : 7 - 2 = 5 (the range)...bur dont get this confused by the interquartile range..it is not the same as the range.
Answer: C, D
Step-by-step explanation:
31 - use the Pythagorean theorem to find the distance
a = 45
b = 28
plug in values
c = 53
answer choice C
32 - non linear functions are functions that aren't straight. if a function has anything besides a constant or an x variable to the power of 1, it is not linear
A - this is linear because -18 is a constant
B - this is linear because it only contains constants and an x variable to the power of 1
C - this is linear because it only contains an x variable to the power of 1
D - this is not linear because the x variable is on the bottom of the fraction, so x is to a power of -1
answer choice D

Answer:
(2,3)
Step-by-step Explanation:
2x - y = 1
-y = -2x + 1
y = 2x - 1
4x + y = 11
4x + 2x -1 = 11
6x = 12
x=2
y=2x-1
y=2(2)-1
y=3
