Step-by-step explanation:
the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Answers
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

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
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
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.

Answers
Answer:
Saints; they have a larger mean value of about 14 points
Step-by-step explanation:
The mean is the best to use here since we are trying to determine the best overall record. Adding up all of the scores for the Saints will get you a total of 210, which then has to be divided by the number of numbers, which is 15. The Saints' mean is larger than the mean for the Cowboys, making your answer "Saints; they have a larger mean value of about 14 points".

Answer:
Step-by-step explanation:
Let's start by finding the sum of the list of nine numbers, which we can then use to find the value of the remaining two numbers in the list:
Sum of the nine numbers = mean * number of numbers = 17 * 9 = 153
Let the three modes be a, b, and c. Since they are modes, each of them must appear at least twice in the list.
Let's assume that the numbers in the list are arranged in non-decreasing order. Then we have:
a ≤ b ≤ c
Since a, b, and c are modes, each of them must appear at least twice in the list. We have three cases to consider:
Case 1: Each of a, b, and c appears exactly twice in the list.
In this case, the remaining three numbers in the list are:
x1 = a + 4
x2 = b + 1
x3 = c - 8
We know that x1, x2, and x3 are distinct and not modes of the list. Therefore, they must be among the six numbers in the list that are not equal to a, b, or c. Let's call these numbers d, e, and f, where:
d ≤ e ≤ f
Then we have:
a + b + c + x1 + x2 + x3 + d + e + f = 153
3(a + b + c) + 3(d + e + f) = 153 + x1 + x2 + x3
Since x1, x2, and x3 are distinct and not modes of the list, we have:
x1 > c
x2 > b
x3 < c
Therefore, we can write:
x1 = c + k1
x2 = b + k2
x3 = a + k3
where k1, k2, and k3 are positive integers.
Substituting these expressions into the equation above, we get:
3(a + b + c) + 3(d + e + f) = 153 + a + b + c + k1 + k2 + k3
Simplifying, we get:
2(a + b + c) + 3(d + e + f) = 153 + k1 + k2 + k3
Since k1, k2, and k3 are positive integers, the right-hand side of this equation is at least 3. Therefore, we have:
2(a + b + c) + 3(d + e + f) ≥ 156
We want to find the value of 3(a + b + c), so let's isolate this term:
3(a + b + c) = 2(a + b + c) + (a + b + c)
Since the left-hand side is three times the sum of a, b, and c, and the right-hand side involves the sum of a, b, c, d, e, and f, we need to express d, e, and f in terms of a, b, and c.
From the inequality a ≤ b ≤ c, we have:
a + k3 ≤ b + k2 ≤ c + k1
Adding 4 to the first inequality, we get:
a + k3 + 4 ≤ b + k2 + 4 ≤ c + k1 + 4
Adding -8 to the second inequality, we get:
a + k3 + 4 ≤ c + k1 - 4 ≤ b + k2
Therefore, we can choose d = a + k3 + 4, e = c + k1 - 4, and f = b + k2. Then
Given F= {3, 5, 7, 9, 11, 13}
and G= {2, 5, 8, 11}

Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
