The students in art class are designing a stained-glass window to hang in the school entryway. The window will be 3 feet tall and 4 feet wide. Here is their design → They have raised $100 for the project. The colored glass costs $5 per square foot and the clear glass costs $2 per square foot. The material they need to join the pieces of glass together costs 10 cents per foot and the frame around the window costs $4 per foot. Do they have enough money to cover the cost of making the window?

Answers

Answer 1

Answer:

They dont have enough money

Step-by-step explanation:

Colored Glass =

$5/ 1 sq = 60 / 12 sq

Clear Glass =

2/1 = 24 / 12

Materials =

.1/ 1= 1.2 / 12

Frame=

$4 / 1 ft = 28 / 12

ADD THE TOTALS

60+24+1.2+28 = 113.2

Answer 2

Students do not have enough money to cover the cost of making the window.

Given that, the window will be 3 feet tall and 4 feet wide.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Area of a rectangle =3×4

= 12 square feet

Now, the total cost = 5+2+0.10+4

= $11.1

The cost per 12 square feet area

= 12×11.1

= $133.2

Therefore, students do not have enough money to cover the cost of making the window.

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.

(PLEASE HELP) What is the slope of the line that contains the points (2, −7) and (−1, 5)?

B: negative one fourth
C: one fourth
D: 4

Answers

The answer is -4

You do 5 - -7=12 and then do -1 -2 which is -3 and then you do 12/-3=-4

Equation m = -4 gives the slope of the line.

What exactly is a line equation?

A line's equation is written as y = mx + b, where m denotes the slope and b the y-intercept.

And m (x - x1) = y - y1

y = the second point's y-coordinate

y1 = the y-coordinate for point one, m = the slope, and x = the x-coordinate for point two.

x1 = the point one's x coordinate

The m = y/x slope

Given the data,

Right now, A is valued at

Let P be the initial point ( 2 , -7 )

Let Q be the second point ( -1 , 5 )

The slope of the line is now given by m = (y2 - y1) / (x2 - x1).

Slope m is equal to (-7 - 5) / (2 - (-1)

The equation is simplified to give Slope m = -12 / 3.

Slope m = -4

Hence, m has a value of -4.

As a result, the line's slope is m = -4.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

Becky takes out a loan for $5,000. She plans to repay the loan in 8 years. The interest rate is 7.3% compounded annually. How much will she have to pay in interest?

Answers

We can solve this equation by simply doing:
(0.073 x 5,000) x 8
$2920 is our total interest :)

Answer:

$3785.53

Step-by-step explanation:

You want the interest amount due at the end of 8 years on a $5000 loan at 7.3% compounded annually.

Future value

The amount due is multiplied by (1 +0.073) each year. After 8 years, the amount due will be ...

5000(1.073^8) ≈ 8785.53

Of that, 5000 is the principal amount, so the remainder is interest.

interest = $8785.53 -5000

interest = $3785.53

Becky will have to pay $3785.53 in interest.
