A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 3840 seats. The students left 2496 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?

Answers

Answer:

35%

Step-by-step explanation:

Answer:

35%

Step-by-step explanation:

First, we must calculate how many seats are taken by 6th graders. We do this by subtracting the total seats by vacant seats. 3840-2496=1,334. Then, we must find the percent of students that were 6th grade who filled the seats. We do this by dividing all the chairs taken by the 6th graders and divide it by the total chairs which gets you .35. And with percentages, you move the decimal place two times to the right which gets you 35%.

horizontal or vertical. The vertices are all
located in the same quadrant where the x
value is negative. What are the possible
coordinates of the square?

Answers

Answer:

7

Step-by-step explanation:

perimeter - 7+7+7+7=28

area - 7×7 = 49

it's a square so all sides are the same length.

area is length times width

perimeter is all sides added together.

Answer: Medians, Less

Part A

Use the measures of center from the box plots to make an inference about the data. Use the drop-down menus to explain your answer.

Based on the medians, the plants in Group A grew

less on average, as compared to the plants in Group B.

Part B Answer: Greater, Less

The range and IQR are greater

in Group B as compared to Group A, so there is less variability in the growth of plants in Group B.

Elis, Raine and Avery buy a boat for $33 000.
Elise pays $12 000, Raine pays $6000 and Avery pays the rest.
Six years later they sell the boat for $25 300.
They share the money in the same ration that they bought the boat.
How much money does Avery lose on the sale of the boat?

Answers

Amount Avery paid: 32,000-12,000-6,000 = 15,000

Divide portion she paid by total cost:

15,000/33,000

Simplify to 15/33

Multiply the amount the boat was sold for by her portion:

25,300 x 15/33 = 11,500

Subtract the amount she got from the amount she paid:

15,000 - 11,500 = 3,500

She lost $3,500

yes

Answer and Step-by-step explanation:

The independent variable is m, and the dependent variable is h.

This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.

With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

There is a theory that children wearing superhero costumes are more likely to harm themselves because of the unrealistic impressions of invincibility that these costumes could create. Below there is data about the severity of injury (on a scale from 0, no injury, to 100, death) for children reporting to the emergency center at hospitals and information on which superhero costumes they were wearing (Spiderman, Superman, Batman).

Compute the following descriptive statistics for each group. (30 points total)
a. Mean
b. Sample size (n) for each group
c. Standard Deviation
d. Square root of n
e. Standard error of the mean (SEM)

Answers

Answer:

[tex]Mean = 47[/tex]

[tex]n = 6[/tex]

[tex]s= 16.56[/tex]

[tex]\sqrt n = 2.45[/tex]

[tex]SEM = 11.55[/tex]

Step-by-step explanation:

Given: The above data

Solving (a): Mean of each group

Mean is calculated as:

[tex]Mean = \frac{\sum x}{N}[/tex]

[tex]Mean = \frac{55 + 31 + 58 + 20 + 47 + 37+68 + 32 + 85 + 69 +58 + 52+26 + 47 + 30 +35 + 53 + 43}{18}[/tex]

[tex]Mean = \frac{846}{18}[/tex]

[tex]Mean = 47[/tex]

Solving (b): The sample size of each group

This is the number of rows in each group.

Hence:

[tex]n = 6[/tex]

Solving (c): Standard deviation (s)

This is calculated as:

[tex]s = \sqrt{\frac{\sum (x - \bar x)^2}{N}}[/tex]

So, we have:

[tex]s= \sqrt{\frac{(55 - 47)^2 + (31 - 47)^2 +......... + (43 - 47)^2}{18}}[/tex]

[tex]s= \sqrt{\frac{4936}{18}}[/tex]

[tex]s= \sqrt{274.22}[/tex]

[tex]s= 16.56[/tex]

Solving (d): Square root of n

[tex]\sqrt n = \sqrt 6[/tex]

[tex]\sqrt n = 2.45[/tex]

Solving (e): SEM

This is calculated as:

[tex]SEM = \frac{s}{\sqrt N}[/tex]

[tex]SEM = \frac{47}{\sqrt{16.56}}[/tex]

[tex]SEM = \frac{47}{4.07}[/tex]

[tex]SEM = 11.55[/tex]
