Answer:
y = 21
x = 8
Step-by-step explanation:
AB = 180
27 + 3y = 90°
-27 -27
-----------------------
3y = 63
÷3 ÷3
--------------
y = 21
x + 27 + 3y + 8x + 18 = 180
9x + 45 + 3(21) = 180
9x + 45 + 63 = 180
9x + 108 = 180
-108 -108
-----------------------
9x = 72

Use the graph to find the relationship between the two variables. Select all that apply.
The variables are 2 and 7.
The variables are dollars and hours.
Hours is the independent variable and dollars is the dependent variable.
Dollars is the independent variable and hours is the dependent variable.
The relationship is x = 3.50y.
The relationship is y = 3.50x.
By using the graph, all of the true statements that apply include the following:
B. The variables are dollars and hours.
C. Hours is the independent variable and dollars is the dependent variable.
F. The relationship is y = 3.50x.
What is a proportional relationship?In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:
y = kx
Where:
y represents the cost in dollars.x represents the number of hours.k is the constant of proportionality.Next, we would determine the constant of proportionality (k) by using the various data points from table D as follows:
Constant of proportionality, k = y/x
Constant of proportionality, k = 3.5/1 = 7/2 = 10.5/3
Constant of proportionality, k = 3.50
Therefore, the required linear function is given by;
y = kx
y = 3.50x

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)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answer:
$10,000
Step-by-step explanation:
Cross multiply and divide by 55.
Hope this helps!
$10000
Step-by-step explanation:
5500 = 55% × amount paid for the car(p)
5500 = 55÷100 × p
5500×100 = 55p
550000 = 55p
550000÷55 = 55p÷55
10000 = p

The length of ribbons found at a seamstress are listed. 3, 11, 11, 13, 13, 21 What is the appropriate measure of variability for the data shown, and what is its value? The mean is the best measure of variability and equals 11. The median is the best measure of variability and equals 11.5. The range is the best measure of variability and equals 18. The IQR is the best measure of variability and equals 2.
Answer:
(d) The IQR is the best measure of variability and equals 2.
Step-by-step explanation:
You want the best measure of variability of the data set {3, 11, 11, 13, 13, 21}.
VariabilityMean and median are measures of the center of the set of data, not its variability. The variability is measured by the range, interquartile range (IQR), or standard deviation.
Here, the range is the difference between the maximum and minimum values, 21 -3 = 18. The quartiles are 11 and 13, so the IQR is 13 -11 = 2.
OutliersThe minimum and maximum values are more than 1.5×IQR = 3 away from the upper and lower quartile values, so can be considered to be outliers. When we exclude the outliers from the data set, we have ...
{11, 11, 13, 13}
The best measure of the variability is the IQR, which is 2—corresponding to choice 4.

What is (8f–9)–(9f–6)
Hey there!
(8f - 9) - (9f - 6)
= 8f - 9 - 9f + 6
= 8f - 9f - 9 + 6
= -f - 3.
Steps :-
Remove the brackets.Bring the like terms together.Simplify the equation.Hope it helps ya!
Answer:
-1 ( f +3) or -f - 3
Step-by-step explanation:
( 8f - 9 ) - ( 9f - 6 )
Add like terms:
8f - 9f = -1f = -f
-9 - -6 = -3
-f - 3
simplify:
-1 ( f +3)

Answer: 1. Negative number
2. Natural number
3. Positive number
4. Integers
5. Number line
6. Opposite numbers
Step-by-step explanation:
1. The first statement says a number that is less than zero, which means any negative number would be less than zero. For example (-1), (-2), etc.
2. The second statement is asking for numbers belonging to the counting set, which means starting from one (1). Natural numbers are numbers that start from 1 and don't include negative numbers or zeros.
3. The third statement says the number that is greater than zero, as negative numbers are smaller than zero and the natural number option has already been chosen above, we will consider positive numbers.
4. Whole numbers consist of both negative and positive integers including zero. Therefore, a set of whole numbers will be written as integers.
5. Number line is a line that represents both negative and positive numbers.
6. Consider an example- (+5) and (-5), both the numbers are the same but with different signs, making them opposite of each other. Therefore, the correct answer would be opposite numbers.

When you divide a positive integers n by 4, the quotient is 6. Find the sum of all possible values of n.
The answer is 102.
The way we get this answer is by disregarding the remainders.
The only way to get the quotient to be six when dividing by four, is for the number to be greater than or equal to 24. The first number is 24.
24 / 4 = 6
25 / 4 = 6R1
26 / 4 = 6R2
27 / 4 = 6R3
These are the possible numbers, because once you get to 28, the quotient becomes 7.
The sum of 24, 25, 26, and 27 is 102.
The required answer is 102.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
When dividing by four, the quotient can only be six if the number is higher than or equal to 24. 24 is the first digit.
24 / 4 = 6
25 / 4 = 6R1
26 / 4 = 6R2
27 / 4 = 6R3
These are the possible numbers, because once you get to 28, the quotient becomes 7.
The required sum = 24 + 25 + 26 + 27 = 102.
The sum of the all possible values of n is 102.
