The relation Q is described as a list of ordered
pairs, shown below.
Q = {(-2. 4), (0.2). (-1,3), (4.-2)}
Domain
Range

Answers

Answer 1

Answer:

Domain = -2, 0, 01,4

Range = (4,2,3,-2)

Step-by-step explanation:

In any set of ordered pair given in form of (x1,y1), (x2,y2)......

domain set of first values(x1,x2) in every pair for x (they can be termed as x coordinates)

range is set of second value in each pair (i.e y1, y2) ( they can be termed as y coordinates)

_____________________________________________

Given ordered pair

Q = {(-2. 4), (0.2). (-1,3), (4.-2)}

thus domain will be first number in each pair

domain = -2, 0, 01,4

Range will be first number in each pair

Range = (4,2,3,-2)

A waitress sold 15 ribeye steak dinners and 28 grilled salmon dinners, totaling $551.97 on a particular day. Another day she sold 24 ribeye steak dinners and 14 grilled salmon dinners, totaling $581.91. How much did each type of dinner cost?

Answers

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y = $551.97 (a)

=================== -

33x = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Ribeye is 18.54 and salmon is 9.78

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.

Answers

To determine the range and IQR (interquartile range) based on the given box plot, let's first define these terms:

- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).

In the given box plot:

- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).

Based on the information provided in the box plot, we can determine the range and IQR as follows:

- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.

Now we can calculate the range and IQR:

- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23

Therefore, the correct statement is:

The range is 37, and the IQR is 23.

Answer:

The range is 37, and the IQR is 23.

Step-by-step explanation:

A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.

Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.

From the given information, the five-number summary of the Jumping Jacks box plot is:

Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52

Range

The range is the difference between the maximum and minimum values. Therefore, the range for the data is:

$\sf Range = 52 - 15 = \boxed{\sf 37}$

Interquartile range (IQR)

The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:

$\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}$

Summary

The range is 37, and the IQR is 23.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Answer:

Step-by-step explanation:

As we know the full angles of a polygon is 360°

And

Each side has angle 24°

So,

n = 360/24

n = 15 sides

I hope my answer helps you.

Answer:
The polygon has 5 sides.

Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.

=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

To understand how to do this problem, we have to look at examples to figure it out. One example would be, if I had a whole cake and cut into 2 pieces I would have two halves, and if I cut it into 4 pieces, I'll have 4 quarters of cake, so 2/2 (two halves) = 4/4 (4 quarters). If I ate 1/2 I would have

(Keep in mind that Equivalent fractions are fractions that are equal to each other)

So to solve these we have to figure out the equal fractions. To do this, we start by multiplying by 2.

(the * symbol is multiplication)

So 3/4 would be 3*2=6 and 4*2=8 so it would be 6/8

Now we can try multiplying it by 3

3*3=9 and 4*3=12 so the 2nd would be 9/12

And we multiply it by 4 now,

3*4=12 and 4*4=16 so the 3th would be 12/16

So, therefore, the answers for 3/4 are 6/8, 9/12, & 12/16.

I'm also going to give you a simplified number that you can use to solve the other problems easier.

3/7 is 3/7. (cannot be simplified)

18/27 is 2/3.

20/80 is 1/4.

You can use these three numbers to start and multiply by 2 and 3 for the other two numbers.

I just gave you a very easy was to solve them and a simple calculator or doing the simple math will be able to help you figure out the rest.

Good luck!
