Determine the line of reflection. Reflection across the x-axis Reflection across x = −6 Reflection across the y-axis Reflection across y = −6

Answers

I apologize for the confusion. Let me explain:

To determine the line of reflection, you can look at the coordinates of the corresponding vertices of the two polygons.

If you compare the coordinates of point A and A' (the corresponding vertices of the two polygons), you will notice that the x-coordinates are the same but the y-coordinates are different. Specifically, A has a y-coordinate of -4 and A' has a y-coordinate of -11.

This means that the line of reflection must be a horizontal line that passes through the midpoint between -4 and -11. The midpoint is (-4+(-11))/2 = -7.5. Therefore, the line of reflection is the horizontal line that passes through (-7.5, 0) on the coordinate plane, which is the y-axis.

I simply multiplied the equation on both sides by the denominators of each fraction to get whole numbers. You can also do this by multiplying by 20, since the product of the denominators is 20 and will guarantee to create a numerator that creates a fraction that is also a whole number.

The set designers of a school play need to determine the cost of the gold paper they’ll need to create stars in the shape of the shaded region in the figure below.

The gold paper is being sold at Michaels for $2.45 per square centimeter.


The set designers have a $6,000 budget to make these stars. Do they have enough money to make 50 stars?

The set designers of a school play need to determine the cost of the gold paper theyll need to create

Answers

Answer: Yes, they do.

Step-by-step explanation: You have to calculate the area of the star; you do this by calculating the area of the square and subtracting the area of the unshaded parts, which is a quarter of a circle.

Therefore,

15^2 - pi * 7.5^2 = 48.28541324 cm squared

Multiply this answer by $2.45 for one star:

Equals $118.2992624

Multiply by 50,

Equals $5,914.96

Since this is less than $6,000 they have enough money to make 50 stars

Yes they do have enough

-2x-5y=3 3x-8=-6 solve by substition

Answers

Maybe use photo math i guess

Answer:

x = 2/3

y = -13/15

Step-by-step explanation:

3x – 8 = -6

+8 +8

[addition property of equality]

3x = 2

÷3 ÷3

[division property of equality]

x = 2/3 → -2x – 5y = 3

[substitution property]

-2(2/3) – 5y = 3

[distributive property]

-4/3 – 5y = 3

[Create the proportional equivalent of each term so that all terms share the same denominator]

-4/3 – 15y/3 = 9/3

[multiplication property of equality]

3 ( -4/3 – 15y/3 ) = 3 ( 9/3 )

[distributive property]

-4 – 15y = 9

+4 +4

[addition property of equality]

-15y = 13

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.
