Explain why the order in an ordered pair is important
Answers
Step-by-step explanation:
An ordered pair is the x-coordinate and the y-coordinate of a point. The order is important because, without a set order, there would be no way to know which was the x and which was the y.
The x-coordinate always comes first, before the y-coordinate.
(x, y)
Step-by-step explanation:
The order in an ordered pair is important because it indicates the location of the given point in a coordinate plane.
In an ordered pair, (x, y):
The first number, (x ) represents the first coordinate. It provides the location of the point relative to the horizontal axis of the coordinate plane.The second number, (y ) represents the second coordinate. It provides the location of the point relative to the vertical axis of the coordinate plane.We cannot switch the values of the first and second coordinates; otherwise, the ordered pair will provide a different location on the coordinate plane.
For instance, if we're given the point, (3, 2), this means that x = 3, and y = 2. This is not the same as (2, 3), as the coordinates imply that x = 2, and y = 3.
Please see the attached screenshot where it shows how these two points have varying locations.

According to the Community College Research Center at the Teachers College of Columbia University in New York, 32% of community college students work full-time (full-time defined to be a person working 35 or more hours per week). Bryanna believes that this percentage may be higher among CBC students, so she decides to take a survey of CBC students to determine if her hypothesis is correct or not.
Required:
What is an appropriate formal hypothesis statement for Bryanna's study?
Answers
According to her study, we have that:
The null hypothesis is [tex]H_0: p = 0.32[/tex]The alternative hypothesis is: [tex]H_1: p > 0.32[/tex]At the null hypothesis, it is tested if the CBC's students proportion is the same as all community college students, that is, of 32%, hence:
[tex]H_0: p = 0.32[/tex]
At the alternative hypothesis, it is tested if the proportion for CBC's students is greater than 32%, that is:
[tex]H_1: p > 0.32[/tex]

What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given,
Total paid = $296
Number of tickets = 16
Cost per tickets = 296/16 = $18.5
This cost excludes the $5.75 saved due to the group.
Original price = $18.5 + $5.75 = $24.25
Hence "The regular price of a ticket to the game will be $24.25 based on the given data".

how do you solve 15 divided by 2/9
Answers
Answer:
67.5 or 67 1/2
Step-by-step explanation:
15 ÷ 2
___________
9
The numbers in 15 divided by 2/9 are labeled below:
15 = whole number
2 = numerator
9 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
15 x 9 2 = 135
____
2
Thus, the answer to 15 divided by 2/9 in fraction form is:
135
_____
2
To make the answer to 15 divided by 2/9 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
135 / 2 = 67.5
The answer is rounded to the nearest two decimal points if necessary.
135/2 is an improper fraction and should be written as 67.5 or 67 1/2.
Hope this helps, have a nice day/night! :D
Answer:
67.5
Step-by-step explanation:
15 = 135/9
