A, the interquartile range is 10, does not fit.
The interquartile range is found by subtracting the upper quartile and the lower quartile; in a box-and-whisker plot these are the outer edges of the box. In this case, they are 40 and 20; 40-20 = 20, not 10.

Answer: x = 3</h3>
To get that answer, we replace y with 8 and then isolate x.
5x-7 = y
5x-7 = 8
5x = 8+7
5x = 15
x = 15/5
x = 3
For this, you just need to add up the team points together. Also remember that the problem says "60 pts or less", not "less than 60 pts". This means teams with 60 pts will count for the question.
Team 1: 
Team 2: 
Team 3: 
Team 4: 
From the math above, we can conclude that 2 teams had won 60 or less.
The answer is a. y=3/4x + 4
Answer:

Step-by-step explanation:
The point-slope formula for a straight line is
y - y₁= m(x - x₁)
x₁ = 1; y₁ = -1; m = 4
Substitute the values

The figure shows the graph of the equation with slope 4 passing through (1, -1).
