Find the mean of the integers: 17, -25, 3, -29, -15, 7
Answers
Answer: -7
Step-by-step explanation: To find the mean, here is the equation =
Divide the sum of all values in a data set ÷ the number of values = mean (average)
Step 1 :
So we do =
17 + -25 + 3 + -29 + -15 + 7 = -42
So the sum of the integers is -42
Step 2 :
We divide the sum by the number of values.
17, -25, 3, -29, -15, 7
1 2 3 4 5 6
So there are 6 values.
We do =
-42 ÷ 6 = -7
So the mean (average) of these integers is -7

A circle is painted in the center of a basketball court. If the diameter of the circle is 12 feet, what is the approximate amount of space inside of the circle? (Use 3.14 as an approximation of pi.)
Answers
Answer:
37.68
Step-by-step explanation:
You have to multiply the diameter by pi (3.14). If it was radius, then you have to multiply the radius twice with pi. (R x R x 3.14)
ANSWER: 37.68
Why? Well this question is asking for the circumference...and you get the circumference by multiplying 3.14 (pi) by the diameter.
Final Notes: The formula for finding the circumference with the diameter is
(C = \(\pi\)d) (diameter times 3.14)
if you want the formula for finding the circumference with only the radius here you go, (Radius times 3.14 then times it by 2)
(C = 2\(\pi\)r)

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

5. Rational numbers are sometimes irrational.
6. Rational numbers are never irrational.
7. Integers are always rational numbers.
Answers
Answers: statements 1, 2, 6 and 7
=======================================================
Explanation:
I'll briefly go through each statement to mention why it's true or false.
This one is a bit tricky. Some math books define the natural numbers to be N = {1, 2, 3, ...} where 0 isn't included, while other textbooks include 0. The inclusion/exclusion of zero seems arbitrary and depends on other context of the math theorems used. The set of whole numbers is more consistent and it is W = {0, 1, 2, 3, ...} basically it's the definition of natural numbers where 0 is included. So if 0 is defined to be a natural number in your textbook, then statement 1 is true. Otherwise, it's false.This is true. A rational number like 2/3 isn't a whole number, but something like 3/1 = 3 is a whole number. Any whole number can be written as itself over 1.This is false. An integer like -7 is not in the set of natural numbers.This is false. The very definition of "irrational" means "not rational". The two types of numbers are complete opposites. An irrational number is one where we cannot write it as a ratio of integers. A famous example is pi = 3.14... as we can't write it as a fraction of integers. An approximation could be something like 22/7, but we don't capture the full picture of what pi really is.This is false. Refer to question 4 above. The set of rational numbers vs irrational numbers do not overlap at all.This is true. Refer to questions 4 and 5. This is true. We can write any integer as itself over 1. For example, the integer -12 is the same as -12/1 to show that it is rational. This idea is similar to what I mentioned in question 2.After going through all seven statements, we definitely know that statements 2, 6, 7 are true. Statements 3,4,5 are definitely false.
Statement 1 is the only thing left. If your teacher mentioned 4 true statements, then statement 1 has to be true. This in turn means that your teacher is defining 0 to be a natural number.

Answer:
The arithmetic sequence expression for the given sequence 6, 9, 12, 15, 18....... would be aₙ = 6+(n-1)3.
What is an arithmetic sequence?
A progression or sequence of numbers known as an arithmetic sequence maintains a consistent difference between each succeeding term and its predecessor.
The common difference of that mathematical progression is the constant difference.
'n' denotes the term's position in the supplied arithmetic sequence in the formula for obtaining the general term: a = a1 + (n - 1) d. For instance, a2 denotes the second phrase in the sequence.
So, the given sequence is:
6, 9, 12, 15, 18
Common difference (d) is: 9 - 6 = 3
Then, the sequence expression would be:
aₙ = 6+(n-1)3
Therefore, the arithmetic sequence expression for the given sequence 6, 9, 12, 15, 18....... would be aₙ = 6+(n-1)3.

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
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
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.
