Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Create a number line that represents the solution set of the inequality w divided by 7 > 38. Show all your work
Answers
Answer:
Step-by-step explanation:
To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:
w/7 > 38
w > 7 x 38
w > 266
This means that any value of w greater than 266 satisfies the inequality.
We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:
<--o======(266)---------------->
This represents the solution set of w/7 > 38.

If there are 52 cards in a standard deck, what is the fractional probability of randomly pulling the Queen of diamonds from the deck?
Answers
Answer: 1/52
Step-by-step explanation:
Pulling out a card from a deck out of 52 cards means you have 1/52 chance to pull out the queen of diamonds!
Probability of randomly pulling the Queen of diamonds from a standard deck of 52 cards is 1/52.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There is only one Queen of diamonds in the deck, and there are 52 cards in total.
Each card has an equal chance of being chosen, so the probability of getting the Queen of diamonds is the number of ways to get the Queen of diamonds divided by the total number of possible outcomes.
The probability of randomly pulling the Queen of diamonds from a standard deck of 52 cards is 1/52.
Hence, probability of randomly pulling the Queen of diamonds from a standard deck of 52 cards is 1/52.

Answers
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.

(A) 6
(B) 21
(C) 3

Hint its not D.
Answers
Answer:
A)6
Step-by-step explanation:
Use the triangle inequality theorem, which states that the third side of a triangle can not be greater than or equal to the sum of the other two sides, and can be no less than the or equal to the difference of the two other sides.
The sum is 8+13=21
The difference is 13-8=5
So if we call our third side x, then
\(5
If the lengths of two sides of a triangle measure 8 and 13 units, using triangle inequality theorem, the length of the third side could be 6 units.
What is triangle inequality theorem?The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.
Given the two sides be 8 and 13 units.
Let the third side be x units.
First,
8 + 13 > x
21 > x
x < 21
Second,
8 + x > 13
x > 5
Third,
13 + x > 8
True for all values of x.
So,
5 < x < 21
From the given options, only 6 satisfies our condition.

In order to find equivalent fractions for a fraction is multiply or divide the numerator and denominator by the same number.
For example, 3/4=6/8 because 3x2=6 and 4x2=8, 6/8.
Hope this helps!
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!

Janelle has $20 and is saving $6 per week, how long will it take her to save $50?
Answers
Answer:
6 weeks
Step-by-step explanation:
Janelle is saving $6 per week, so to save $50, she will need:
$50 - $20 = $30 more
To find out how many weeks it will take her to save $30 at a rate of $6 per week, we can divide:
$30 / $6 per week = 5 weeks
Therefore, it will take Janelle 5 more weeks to save $50, for a total of 5 + 1 = 6 weeks.
30/6=5 weeks.

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.
