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.

Step-by-step explanation:
What you have is a kite so the two missing angles are equal.

2y = 360° - 88° - 32° = 240°
y = 120°
1. Two walls of a room or being painted each measure 16 6/2' how many square feet will be painted
2. A rectangular canvas covers 225 inches on a wall if the canvas has a height of 18 inches then what is the base
Answers
Answer:
3.167 ft²
12.5 inches
Step-by-step explanation:
1.)
Measure of each wall : 16 6/2 '
Number of walls = 2
Total area to be painted :
16 6/2' * 2 = (16 + 3) * 2 = 19 * 2 = 38 inches
1 feet = 12 inches
x = 38 inches
12x = 38
x = 38 / 12 = 3.167 ft²
2.)
Area of rectangular canvas = 225
Height = 18
Base, b =?
Area of rectangle = height * base
225 = 18 * b
225 / 18 = 18b / 18
12.5 = b
Base = 12.5 inches

The graph of a sine function is shown. Plot the line that represents the midline of this periodic function.
Answers
Answer: The midline should be a horizontal one, at y=4
Step-by-step explanation: See above answer.
Midline of the periodic function given in the picture will be y = 4.
Mid-line of the periodic function: Midline of a periodic function is the line located half-way between the maximum and the minimum values.
From the graph attached in the question,
Maximum value of the periodic function → y = 5
Minimum value of the function → y = 3
Midline of the function → [tex]y=\frac{3+5}{2}[/tex] ⇒ y = 4
Therefore, midline of the periodic function given in the picture will be y = 4.

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]

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%.
