1. First of all arrange the data set in either ascending or descending order.
12, 19, 24, 26, 31, 38, 53. N = 7 (number of data items)
Median position = 1/2(N + 1)th item = 1/2(7 + 1)th item = 1/2(8)th item = 4th item = 26
First quatile = 1/4(N + 1)th item = 1/4(7 + 1)th item = 1/4(8)th item = 2nd item = 19
Third quatile = 3/4(N + 1)th item = 3/4(7 + 1)th item = 3/4(8)th item = 6th item = 38
Interquatile range = Third quartile - first quatile = 38 - 19 = 19
You find the volume dummy
Answer:
y = mx + b
Step-by-step explanation:
y represents the dependent variable (value you are getting).
m represents the slope of the line.
x represents the independent variable (what you are changing).
b represents the y-intercept, or the y value when x is zero.
Answer:
x = 10
Step-by-step explanation:
Proof: If a line is parallel to one side of the triangle, then it divides the other two sides proportionally.
6/9 = x/15
9x = 90
x = 10
Step-by-step explanation:
7x + 3x + 90= 180
10x= 180-90
10x= 90
x= 90/10
x=10
