Lines B and C are perpendicular ⇒ answer C
Step-by-step explanation:
The product of the slopes of the perpendicular line is -1
The slopes of the parallel lines are equal
The slopes of two lines are and
1. If × = -1, then the two lines are perpendicular
2. If = , the the two lines are parallel
The equation of a line in slope-intercept form is y = m x + c, where m is
the slope of the line
Line A: y = x + 2
The slope of the line is =
Line B: y = x + 7
The slope of the line is =
Line C: y = 2 x + 4
The slope of the line is = 2
Line D: x +
The slope of the line is =
∵ =
∵ = 2
∵ × 2 = -1
∴ Line B and Line C are perpendicular because the product of their
slopes is -1
Lines B and C are perpendicular

The statistical questions are:
- On average, how many books does each person in the United States read each year
- Which book was read most by students in the class, this summer
The non-statistical questions are:
- How many acts are there in the play Romeo and Juliet
- How many books are in the class right not
<h3>How to categorize the questions?</h3>
As a general rule, questions whose answers can be determined using a single data point are non-statistical questions.
Using the above rule, we have the non-statistical questions to be:
- How many acts are there in the play Romeo and Juliet
- How many books are in the class right not
As a general rule, questions whose answers cannot be determined using a single data point are statistical questions.
Using the above rule, we have the statistical questions to be:
- On average, how many books does each person in the United States read each year
- Which book was read most by students in the class, this summer
Also, both statistical questions are numerical

Answer:
No, it does not equal to 10:20. The ratio is 1 to 5. So it is impossible for it to be 10:20, it can either be 4:20 or 10:50.
Step-by-step explanation:
It would just be -3>-5 and 3+2=5. This symbol (<span>^) simply means and.</span>
