a) A coat that costs £46.50
after a 7% price reduction

b) A jumper that costs £32.80 after a price increase of
6%

Answers

Answer:

50 and 30.94

Step-by-step explanation:

The coat cost 46.5 pounds after a 7 percent reduction

so we can write:

46.5⇒ (100-7)⇒ 93 percent x(the initial price) ⇒ 100 percent

using the proprtionality relation:

x= (100*46.5)/93 = 50

so the initial price of the coat is 50 pounds

The jumper costs 32.8 pounds after an increase of 6 percent

so:

32.8⇒(100+6)⇒ 106 percent x (the initial price)⇒ 100 percent

using proportionality:

x= (100*32.8)/106 = 30.94

the initial price is 30.94 pounds

Answer:

a. £50

b. £30.94

Step-by-step explanation:

100-7=93

x×93/100=46.50

x×93=46.50×100=4650

x=4650/93=50 £

100+6=106

y×106/100=32.80

y×100=32.80×100=3280

y=3280/106≈30.94£

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.

Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.

Answers

Answer:

Step-by-step explanation:

We use a for Adult and s for Student.

Assuming this, you have to start by writing two equations from the information provided:

900 total tickets were sold

a+s=900 ------(i)

they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50

2820=4a+2.5s ------(ii)

lets solve for a in the first equation:

a=900-s

we can plug this into the second equation and solve for s

2820=4(900-s)+2.5s

2820=3600-4s+2.5s

2820=3600-1.5s

-780=-1.5s

s=520

we can plug this into the first equation and solve for a:

a+520=900

a=380

Total adult ticket sold : 380

Total student ticket sold = 520

Cost of adult tickets = 380 * 4 = $1520

Cost of student tickets = 520 * 2.5 = $1300

A circle of center (-3 , -2) passes through the points (0 , -6) and (a , 0). Find a?

Answers

Answer:

-4.5

Step-by-step explanation:

Answer:

$ a=1.58, \: \: a =-7.58$

Step-by-step explanation:

Since, circle of center (-3 , -2) is passing through the points (0 , -6) and (a , 0).

Therefore, points (0 , -6) and (a , 0) will be equidistant from the center of the circle (-3 , -2).

Hence,

Distance between (0 , -6) and (-3 , -2) = Distance between (a , 0) and (-3 , -2).

$ [0-(-3)]^2 + [-6-(-2)]^2=[a-(-3)]^2 + [0-(-2)]^2$

$ [0+3]^2 + [-6+2]^2=[a+3]^2 + [0+2]^2$

$ [3]^2 + [-4]^2=[a+3]^2 + [2]^2$

$ 9 + 16=[a+3]^2 + 4$

$ 25=[a+3]^2 + 4$

$ 25-4=[a+3]^2$

$ 21=[a+3]^2$

$ [a+3]^2=21$

$ [a+3]=\pm\sqrt {21} $

$ a=\pm\sqrt {21} - 3$

$ a=\sqrt {21} - 3, \: \: a =-\sqrt {21} - 3$

Solving the Question

We're given:

There were 478 people in total.$1.75 per child$2.25 per adultTotal revenue of $975We must find the number of children and adults who swam.

Set variables:

Let a represent the number of children who swam.

Let b represent the number of adults who swam.

Create equations

Because we've set two variables, we need two equations to be able to find the answers.

One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.

Number of people:

$a+b=478$

The number of children + the number of adults = 478 in total

Price:

$1.75a+2.25b=975$

$1.75 per child + $2.25 per child = $975 in total

Solve equations$a+b=478$$1.75a+2.25b=975$

We can solve this question using substitution, where we plug one equation into the other.

Isolate a in the first equation:

$a+b=478\\a=478-b$

Plug the first equation into the second equation by replacing a:

$1.75a+2.25b=975\\1.75(478-b)+2.25b=975$

Solve for b:

$1.75(478-b)+2.25b=975$

⇒ Open up the parentheses:

$836.5-1.75b+2.25b=975\\836.5-0.5b=975$

⇒ Subtract 836.5 from both sides to isolate b:

$-0.5b=138.5$

⇒ Divide both sides by -0.5:

$b=277$

Therefore, there were 277 adults in total.

Solve for a:

$a+b=478$

⇒ Replace b with 277:

$a+277=478\\a=201$

Therefore, there were 201 children in total.

Answer

There were 201 children and 277 children at the pool that day.

To find the interest earned by Account A, we can use the formula:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $1,500 x 0.04 x 3 = $180

So Account A earns $180 in interest over three years.

Similarly, we can find the interest earned by Account B using the same formula:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $1,500 x 0.06 x (21/12) = $157.50

So Account B earns $157.50 in interest over 21 months.

To compare the interest earned by the two accounts, we can see that Account A earns more interest than Account B, even though the interest rate is lower. This is because the time period is longer for Account A, giving the interest more time to accrue.

Example 1: Two principal amounts and two simple interest rates that would earn equal amounts of interest in one year are:

Principal 1 = $1,000
Rate 1 = 5%
Interest 1 = $50

Principal 2 = $2,000
Rate 2 = 2.5%
Interest 2 = $50

Example 2: Two principal amounts and two periods of time for which the simple interest earned at 2.59% would be equal are:

Principal 1 = $500
Time 1 = 4 years
Interest 1 = $51.80

Principal 2 = $1,000
Time 2 = 2 years
Interest 2 = $51.80

Put the following numbers in order from least to greatest with least at the top and greatest at the bottom.
