Step-by-step explanation:

Count how many numbers there are for each category, ie: 2 numbers fit into the 0-9 category, so the frequency is 2

Answer: Upper left corner

$\begin{array}{|c|c|} \cline{1-2}\text{Number of People} & \text{Frequency}\\\cline{1-2}0-9 & 2\\\cline{1-2}10-19 & 5\\\cline{1-2}20-29 & 2\\\cline{1-2}30-39 & 0\\\cline{1-2}\end{array}$

===========================================================

Explanation:

First off, let's sort the numbers from smallest to biggest.

The sorted list is

2, 5, 12, 12, 14, 15, 18, 24, 24

Now let's organize each of those numbers into the bins of 0-9, 10-19, 20-29 or 30-39

The values 2 and 5 go in the 0-9 bin since they are between 0 and 9The values 12,12,14,15,18 go in the 10-19 bin for similar reasoning as above.The values 24,24 go in the 20-29 binNothing goes in the 30-39 bin since none of the values are between 30 and 39.

Here's one way to represent what's going on so far.

$\begin{array}{|c|c|c|c|c|} \cline{1-5}\text{Bin} & 0-9 & 10-19 & 20-29 & 30-39\\\cline{1-5}\text{Value(s)} & 2,5 & 12,12,14,15,18 & 24,24 & \text{Nothing}\\\cline{1-5}\end{array}$

In the 0-9 bin, we have two values, so we have a frequency of 2 here.The next bin has a frequency of 5 due to the 5 values in here.The third bin has a frequency of 2. The last bin has a frequency of 0.

We can then form the final grouped frequency table.

$\begin{array}{|c|c|} \cline{1-2}\text{Number of People} & \text{Frequency}\\\cline{1-2}0-9 & 2\\\cline{1-2}10-19 & 5\\\cline{1-2}20-29 & 2\\\cline{1-2}30-39 & 0\\\cline{1-2}\end{array}$

which is shown in the upper-left corner.

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.

The number of cookies that were made at a bakery for each of seven days is shown:

108, 96, 96, 84, 108, 240, and 84

The best measure of center for this data set is the-

A: median because all of the values are close to one another in value

B: mean because all of the values are close to one another in value

C: median because 240 is much higher than the other numbers in the data set

D: mean because 240 is much higher than the other numbers in the data set

Answers

To determine the best measure of center for the given data set, we need to consider the values and their distribution.

The data set is as follows: 108, 96, 96, 84, 108, 240, and 84.

The median represents the middle value when the data set is arranged in ascending or descending order. In this case, when we arrange the data in ascending order, we have: 84, 84, 96, 96, 108, 108, 240. The middle value is 96, which is the fourth value in the sorted data set.

The mean is calculated by summing up all the values and dividing by the total number of values. In this case, the sum of the values is 756 (108 + 96 + 96 + 84 + 108 + 240 + 84), and there are seven values. Therefore, the mean is 756/7 = 108.

Comparing the options:

A: median because all of the values are close to one another in value - This is not accurate as the values vary, and the median is not necessarily the best measure of center based on the values being close to one another.

B: mean because all of the values are close to one another in value - This is not accurate as the values are not all close to one another, and the mean is not necessarily the best measure of center based on the values being close to one another.

C: median because 240 is much higher than the other numbers in the data set - This is not accurate as the presence of a single high value does not automatically make the median the best measure of center.

D: mean because 240 is much higher than the other numbers in the data set - This is the most accurate option. The mean takes into account the magnitude of each value and is influenced by extreme values. The value 240 has a significant impact on the mean, making it a better measure of center in this case.

Therefore, the best measure of center for this data set is D: mean because 240 is much higher than the other numbers in the data set.

The median is the middle number as in lowest to highest

Answers

Answer:

Part B: 8 and 2 (more answers ofc)

Part C: Two more dots on 6 (more than one answer tho)

Step-by-step explanation:

Part B:

The added number of dots is 39 at the beginning and the mean is 3.9. (39/10). Since we have to add 2 dots the equation will be (39 + ? + ?) / 12 = Less than 3.9. We also need the range to increase. This means that one of the blanks must be larger than 7 (the largest dot on the dot plot!) I just went with 8 to keep the mean as small as possible. This leaves 1 more blank to figure out. There are multiple answers to this problem but I went with 2 just because then the mean would be 3.5 a better answer than something like 3.58333333333.

Part C:

If you think about it all the dots added up should be 6x12 = 72. Currently all the dots add up to 60. 72-60 is 12. This means that 12 is equal to 2 dots. I guess you could also do 5 and 7, 8 and 4, etc.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?

Answers

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Trash Management charges its customers a fee of $25 plus $8 for each trash can they need emptied. Waste Away charges its customers $12 per trash can with no fee. Write an inequality that can be used to determine the number of trash cans for which it is less expensive for a customer to use Waste Away as their trash service.

Answers

Answer:

after 5 trash cans the waste away would be cheaper

Step-by-step explanation:

28+8x

12x

you would plug in numbers for x until one of them is cheaper in this case waste away is cheaper by $8 after 5 trash cans

There are fewer than six trash cans, so it is less expensive for a customer to choose Waste Away as their trash service.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let x be the number of trash cans.

The cost for Trash Management is 25 + 8x, and the cost for Waste Away is 12x.

To determine the number of trash cans for which Waste Away is less expensive, we need to find the number of trash cans such that the cost for Waste Away is less than the cost for Trash Management, which can be expressed as 12x < 25 + 8x.

Solving for x, we get 12x - 8x < 25, which simplifies to 4x < 25.

Dividing both sides by 4, we get x < 25/4.

Therefore, it is less expensive for a customer to use Waste Away as their trash service if they have fewer than 25/4 = 6.25 trash cans.

Since the number of trash cans must be an integer, the inequality can be rewritten as x < 6.

A sporting goods store is having a sale in which all sleeping bags are discounted by 20%. Priya has a coupon for $5 off the regular price of a sleeping bag. The store first applies this coupon and then takes 20% off the reduced price. If Priya pays $34.40 for the sleeping bag, what was the original price, x, before the sale and without the coupon?

Answers

the original price was "x", which oddly enough is the 100%.

now, let's pluck out of "x" 5 bucks, so that makes it "x-5", that's our new adjusted 100%, from which the lady at the counter is happy to apply a 20% discount. Now, if the lady discounts 20% off of that "x-5" amount, what Priya is really paying for the sleeping bag is just 100% - 20% = 80%, and we happen to know that that 80% was really $34.40.

now, if "x - 5" is the 100%, and we know that 34.40 is the 80%, what the heck is "x"?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} x-5 & 100\\ 34.40& 80 \end{array} \implies \cfrac{x-5}{34.40}~~=~~\cfrac{100}{80} \implies \cfrac{ x-5 }{ 34.40 } ~~=~~ \cfrac{ 5 }{ 4 } \\\\\\ 4x-20=172\implies 4x=192\implies x=\cfrac{192}{4}\implies x=48$

1. The longest pencil is 8 inches and the shortest pencil is 2 inches. Therefore, the difference between the length of the longest pencil and the shortest pencil is 8 - 2 = 6 inches.

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.

3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.

Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27

Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12

To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:

12/27 x 100% = 44.44%

Since 44.44% is less than 50%, the statement is false.
