Answer:

$\huge\boxed{\sf Option \ 1}$

Step-by-step explanation:

For a relation to be a function,

the x-values (domain) in that relation should not repeat.

So,

Here, the set of ordered pair that represents a function is:

{(−4, −4), (−3, −3), (−2, −2), (−1, −1), (0, 0)}

Because in this set:

Domain = {-4, -3, -2, -1, 0}

Also, the values in the domain are not repeated. So, this set is a function.

It is required to find the real number.

What is real number?

Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

Given:

We know that N⊂Z where N represents set of natural numbers and Z represents set of all positive and negative integers.

Since N⊂Z,

Since Z represents set of all positive and negative integers.

Therefore, the sets of which the given set is a subset is the set of natural numbers.

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

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

Step-by-step explanation:

the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?

Answers

Answer: x = 23

Explanation

The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.

(angle ABD) + (angle DBC) = 180

(134) + (2x) = 180

2x = 180-134

2x = 46

x = 46/2

x = 23

Answer: x=23 and the angle relation used was supplementary angles

Step-by-step explanation:

first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Mark is comparing prices of different brands before he goes shopping. Who has the best deal on ice cream? Brand Size & Price Turkey Hill $4.50 for 30 ounces Breyers $15.36 for 128 ounces Ben & Jerrys $2.88 for 16 ounces

Answers

Based on the given information, we need to calculate the price per ounce for each brand to determine the best deal on ice cream.

Turkey Hill: Price per ounce = 4.50 ÷ 30 = 0.15 dollars/ounce

Breyers: Price per ounce = 15.36 ÷ 128 = 0.12 dollars/ounce

Ben & Jerrys: Price per ounce = 2.88 ÷ 16 = 0.18 dollars/ounce

Therefore, the best deal on ice cream is Breyers, with a price of $0.12 per ounce.

Answer:

Breyers has the best deal, at $0.12/ounce.

Step-by-step explanation:

Convert all to the ice cream prices by the ounces in which they're sold to see how much the price is per 1 ounce:

4.5/30 = 0.15

15.36/128 = 0.12

2.88/16 = 0.18

Therefore, for 1 ounce of:

Turkey Hill: $0.15

Breyers: $0.12

Ben & Jerrys: $0.18

What is the median of the data set represented by the dot plot?

Answers

4.5?? I’m not entirely sure though

Answer: 5

Step-by-step explanation:

The median is the middle number of a group of numbers. So, to find the median, first, find out how many numbers there are. You can do this on the dot plot by counting the dots. There are 9 dots.

To find the middle number when the total is odd, you can drop the number down to an even number that will divide in half (or divide the number by two). In this case, you can drop the number to 8 and divide by two. The answer to that is 4. Because there was an odd number of dots, you should use the 4th and then the 5th numbers to determine the middle number. We also count the 5th number because the total was odd. If the total is even, use only one number as the middle number.

Since the 4th and the 5th number are lined up on the 5, that is the median number.

(If you ever have to find two numbers that are not lined up on the same number, you have to add those two numbers and divide by 2 to find the median.)

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

assembly = 40 min

organising the puppets = 13 min

greeting children = 10 min
