Solution:
<u>Step-1: Find the data.</u>
- 70's: 1
- 80's: 1
- 90's: 2
- 100's: 3
- 110's: 4
- 120's: 4
- 130's: 2
- 140's: 1
Data obtained (Smallest to biggest):
- 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140
<u>Step-2: Count the number of digits.</u>
<u>Step-3: Use the formula "Total digits/2".</u>
The 9th digit in the data is the median.
<u>Step-4: Revise the data.</u>
- 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140
The median value of the line plot is 110.
Answer:
x = 145
Step-by-step explanation:
The angles are same side exterior angle and same side exterior angles are supplementary
x +35 =180
Subtract 35 from each side
x = 180-35
x =145
Answer:
Step-by-step explanation:
The given expression is

We will rewrite the expression

When we add the fraction
=
= 8
While Andre says the answer is 
because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.
Andre made mistake in this step
Picture is given below :
Answer:
150 km squared
Step-by-step explanation:
5*1.5=7.5
4*5=20
7.5*20=150
Answer:

Step-by-step explanation:
Slope intercept form is: 
<h2>
Find the Slope:</h2>
Choose 2 points on the graph:
(0,1) (2,0)
Find the slope of the two points:


<h2>Find the Y-Intercept</h2>
The y-intercept, or the point that the line crosses on the y axis, is (0,1).
