1.4.35 Determine Whether The Pair Of Lines Is Parallel, Perpendicular, Or Neither. Y= 8/11X+1 Y= (-11)/8X+1

Answers

Answer 1

Answer:

Answer: They are perpendicular.

Step-by-step explanation:

Our task is to answer the following question?

Are the following lines parallel, perpendicular, or neither?

$\sf{y=\cfrac{8}{11}x+1}$ $\sf{y=-\cfrac{11}{8}x+1}$

Main idea:

Parallel lines have the same slope.
Perpendicular lines have slopes that are opposite reciprocals of each other.

The lines have slopes that are opposite reciprocals; therefore, they're perpendicular.

Sam’s Music Store wanted to take a survey of the age range of people that visited the store. Over the course of a week, they asked 40 people their age as they walked in. Below is a box plot of the collected data. Answer the following questions about the box plot in relation to the problem. 1.When Sam’s assistant was collecting the data she mistakenly noted that the oldest person was 48. The oldest person was actually 50. How will this affect the box plot?

Answers

A box plot contains 5 number summary. The information gathered from the box plot are:
1) minimum number
2) 1st quartile
3) median
4) 3rd quartile
5) maximum

Since the box plot of the collected data is not shown, I can only say that the maximum number will be affected by the error.

maximum number of 48 should have been maximum number 50.
