Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of numbers / number of observation
sum of numbers = 3 x 7 = 21
Median is the number that is at the center or middle of a set of obervations
x + 9+ y = 21
x= lowest number
y = highest number
x + y = 21 - 9
x + y = 12
If x = 1 y = 11
if x = 2 y = 10
if x = 3 y = 9
if x = 4 y = 8
the first 3 are plausible and the median would still be 9 if x = 4, median would be 8

Answer:
12.3
Step-by-step explanation:
You will use cosine to solve for y because you are given the hypontenuse and need to find the adjacent side.
cos 35 degrees = adjacent/hypontenuse
cos 35 = y/ 15
15( cos35 ) = y
y=12.287
=12.3
A right angle degree is always 90 degrees, or 1/4 of the full amount of degrees, which is 360. 90 degrees, is also pi/2 radians, which you will learn in trigonometry and pre-calc.
