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:
25%
Step-by-step explanation:
Given data
original quantity =12
new quantity =15
% increase= new-original/original *100
% increase= 15-12/12 *100
% increase= 3/12 *100
% increase=0.25 *100
% increase=25%
hence the increase is 25%.
To find the slope of the line, use the rise over run formula:

Take any two points from the line and plug them into the formula.
(0,0) and (10, 5)

The slope of the line is 0.5.
Using the form y = mx, the following equation will be your answer:
No.
If a rational number can be an integer, x and y could be 5.5 and .5, or something that adds up to (number).0. This means, if the two non-rational numbers add up, they could be irrational, but the result isn't.
