Noah gathered information on the home states of the swimmers on Team USA. He organized the data in a table. Would a dot plot be appropriate to display his data? Explain your reasoning.This dot plot shows the ages of students in a swimming class. How many students are in the class?
Based on the dot plot, do you agree with each of the following statements? Explain your reasoning.
The class is an adult swimming class.
Half of the students are between 2 and 3 years old.
Answers
Answer:
1. No; 2. 16; 3. No; 4. Yes
Step-by-step explanation:
1. Home states of Olympic swimmers
A dot plot compares frequency counts within groups, usually with small sets of data.
Thus, it is great for visualizing quantitative data.
Home states are qualitative data.
It might be better to use a packed bubble chart, especially if more than 20 to 30 states are on the team.
In such a chart, the frequency with which the state name is mentioned would determine the relative bubble size.
It might look like the imaginary chart shown below.
A dot plot would not be appropriate.
2. Number of students
No. of students = 2 + 1 + 2 + 3 + 2 +1 + 1 + 2 + 2 = 16
3. Is this an adult swimming class?
The ages of the students range from 18 mo to 32 mo.
This is not an adult swimming class.
4. Ages of half the students
Half of 16 students is eight students.
The eight oldest students range in age from 25 mo to 32 mo.
This is between the ages of 2 yr to 3 yr (24 mo to 36 mo), so
Half the students are between 2 yr and 3 yr old.
Answer:
(1. No) (2. 16) (3. No) (4. Yes)

A gem store in Fort Lauderdale received a shipment of 1 1/2 pounds of moonstone crystals if these moonstones crystals if these moonstone crystals were separated into 6 equal bags how much would each bag weigh?
Answers
A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.
How to solveTo solve this problem, we can use the following equation:
total weight / number of bags = weight of each bag
In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:
1.5 pounds / 6 bags = 0.25 pounds per bag
Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

Answers
Answer:
199 cm^2
Step-by-step explanation:
1. First, we have to find the radius. Divide the circumference by pi (3.14): 50/3.14=15.92. This gives us the diameter.
2. Divide the diameter by 2: 15.92/2=7.96. This is the radius.
3. Use the formula for the area of a circle. Area=3.14*7.96^2.
4. Solve this equation and you get the answer: About 199 cm^2
Answer:199
Step-by-step explanation:
the formula for the area of a circle is \(\pi r^{2}\) (pi *radiusto the power of 2)
so the 50 metered wire is the circumference of the circle
to get the area of the circle you need the radius
to get the radius you need to divide 50 by 3.14 (\(\pi\)), that equals to 15.923566879 this is the diameter to get the radius you need to divide it by 2 . radius =7.961783439
formula for area =\(\pi r^{2}\)
\(\pi\)=3.14
3.14ˣ7.961783439ˣ7.961783439=199.044585975
round it to nearest number = 199

Step-by-step explanation:
The expressions, that show the distance between points A and B, are 8 -1 and |-8| -|-1|.
What is distance?The separation between two points the coordinates of two points in space are used in the formula. In coordinate geometry, a two-dimensional or three-dimensional space can be used to calculate the distance between two points using the distance formula. The Pythagoras theorem is sometimes used to calculate the distance between two places.
The length of the line segment bridging two points on a plane is known as the distance between the points.
In the given line:
Position of point A is -8.
Position of point B is -1.
Hence, distance between A and B is = | -1 - (-8) | unit = 7 unit.
Expression 8 -1 = 7

2) 2,4,6.....
3) 3,5,7......
4) 1,4,7,10
5) -1,-2,-3
Answers
Answer:
1) n
2) 2n
3) 2n+1
4) 3n-2
5) -n
Step-by-step explanation:
To write a generalized statement for a pattern using n, we multiply n by the common difference between each term. We add the term number before the first term to this.
1) 1, 2, 3...
For the first question, the common difference is 1 because each term increases by 1. Multiply n by 1.
1n
To find the term number before the first term, we subtract 1 from the first term.
1-1=0
Therefore, our general statement is 1n+0, or just n.
2) 2, 4, 6...
The common difference is 2 because we add 2 each time. Multiply n by 2.
2n
The term number before the first term is equal to the first term - the common difference.
2-2=0
Therefore, our general statement is 2n+0, or just 2n.
3) 3, 5, 7...
The common difference is 2 because we add 2 each time. Multiply n by 2.
2n
The term number before the first term is equal to the first term - the common difference.
3-2=1
Therefore, our general statement is 2n+1.
4) 1, 4, 7, 10...
The common difference is 3 because we add 3 each time. Multiply n by 3.
3n
The term number before the first term is equal to the first term - the common difference.
1-3=-2
Therefore, our general statement is 3n+(-2), or 3n-2.
5) -1, -2, -3...
The common difference is -1 because we subtract 1 each time. Multiply n by -1.
-1n
The term number before the first term is equal to the first term - the common difference.
-1-(-1)
= -1+1 (because two negatives make a positive)
= 0
Therefore, our general statement is -1n+0, or just -n.

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 18Step-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

If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)
Answers
Answer:
A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:
(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.
(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.
(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.
(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.
So, the pairings that always describe a function are:
(a person’s age in years, that same person’s height in inches)
(a person’s weight in pounds, that same person’s height in inches)
(a person’s height in centimeters, that same person’s height in inches)
These three pairings meet the criteria of a function, where each input corresponds to a unique output.
The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)
How did we arrive at this assertion?A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:
1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).
2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.
3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.
4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).
So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

At lunch, there are 7 cartons of milk sold for every 3 juice boxes sold. If 210 drinks are sold on Friday, how many of those drinks are juice boxes?
THIS IS OVERDUE HELP
Answers
Answer: 63 Juice boxes
Step-by-step explanation: So you know that 7(cartons of milk)+3(juice boxes)= 10 so you divide 210 by 10 and you get 21. 21x3 is 63 so 63 juice boxes are sold. To check the answer i did 21x7 and i got 147. 147+63=210
63 juice boxes and 147 cartons of milk are sold.
Explanation-
7 + 3= 10 (the 7 represents the milk cartons and the 3 represents the juice boxes). Since 210 drinks are sold that means you must divide 210 by 10 (since 10 is the total), when you divide 210 by 10 you get 63. So in conclusion the answer is 63.
