The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

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 table shows the possible outcomes of spinning the given spinner twice. Find the probability of the spinner landing on 2 at least once.

The probability?

Type an integer or a fraction

Answers

In the table, there are 16 possible outcomes shown. We want to find the outcomes that have at least one “2” in them. There are 4 outcomes with a “2” in them in the column of 2, and in the row of “2” there are 3 more outcomes. (excluding the outcome we already counted)
This means there are 7 outcomes that have at least one “2” in them, and there are 16 total outcomes.
That means the probability of the spinner landing on 2 at least once is 7/16.

Convert -3x + 2y = 10 into slope-intercept form.

z=32

Step-by-step explanation:

sum of these angles is equal to 180 so we add all of these angles and set it equal to 180

Z+12+2z+z+40=180

4z+52=180

-52. -52

4z=128

/4. /4

z=32

Hopes this helps

Answer:

z = 32° (degrees)

Step-by-step explanation:

Angles in triangle = 180° (degrees)

z + 12 + z + 40 + 2z = 180

2z + 2z + 12 + 40 = 180

4z + 52 = 180

4z = 180 - 52

4z = 128

z = 128/4 → 32

Triangle NGM is reflected across the x-axis, and is dilated by a factor of

what are the coordinates of vertices N'G'M'

$Triangle NGM is reflected across the x-axis, and is dilated by a factor of [tex]2 \frac{1}{2} [/tex]what$

Answers

The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).

Scale factor = $2\frac{1}{2}$

= 2.5

The reflection of point (x, y) across the x-axis is (x, -y).

Here, N(-4, 6)→(-4, -6)

M(-6, 2)→(-6, -2)

G(-2, 4)→(-2, -4)

Now, with scale factor 2.5, we get

(-4, -6)→2.5(-4, -6)→N'(-10, -15)

(-6, -2)→2.5(-6, -2)→M'(-15, -5)

(-2, -4)→2.5(-2, -4)→G'(-5, -10)

Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

TPC also holds some of their equity instruments purely for speculative purposes. TPChas elected to apply the International Financial Reporting Standards in preparation of its annual financial statements and has a 31 August financial year-end.PART AThe following are the details of some of the investments made by TPC:Ordinary sharesTPC holds a portfolio of listed and unlisted shares Listed shares are actively traded by TPC's treasury department to benefit from fair value gains (ie., held for speculative purposes). The current portfolio was acquired at a fair value of R1 248 000 and transaction costs of R15 080 were incurred on acquisition. Unlisted shares are held in private companies, which the board of directors have invested in to benefit from dividends and long-term capital appreciation on the shares. The current portfolio was acquired at a fair value of R1 560 000 and transaction costs of R19.500 were paid on acquisition.Preference sharesThe entity holds convertible preference shares (convertible at the option of the issuer into ordinary shares at a ratio of 1 ordinary share for every 2 preference shares) that was acquired for a purchase price of R2 912 000 and on which transaction costs of R115 180 were incurred.Government bondsTPC holds 10 year government bonds acquired at a fair value of R676 000 and on which transaction costs of R9 750 were incurred.

The market-related interest rate for similar debentures with the same terms as this debenture is 14,1417%. Insignificant transaction costs were incurred in the process of purchasing the debentures.. The objective of TPC's business model is to hold the debenture to collect contractual cash flows.
