Calculate the Mean: 24, 27, 31, 21, 27
Answers
Answer: 26
Step-by-step explanation:
mean is the same thing as finding the average
you add up all the numbers then divide by the amount of numbers there are
24+27+31+21+27=130
130\5=26
A circle has a radius of 7 centimeters (cm).
What is the approximate area of the circle?
Use the approximation of 22/7 for π in your calculations.
Answers
Answer:
154 cm
Step-by-step explanation:
the formula for the area of a circle is: \(\pi r^{2}\)
Instead of \(\pi\) we will use \(\frac{22}{7}\)
\(\frac{22}{7} . (7)^2\\\\\frac{22}{7} . 49\\\\22 . 7 = 154\\\)

Concepts
The Pythagorean Theorem states that the sum of the squares of the two other sides on a right triangle is equal to hypotenuse (longest side) squared. It can be represented by the equation \(a^2+b^2=c^2\). We can also use this formula to solve for the other two legs in the right triangle.
Application
In this case, we're asked to find the length of b in the right triangle, given c as 26 and a as 10. Now, we just apply the formula and solve for b.
Solution
Step 1: Set up equation and simplify.
\(10^2+b^2=26^2\) \(100+b^2=676\)Step 2: Subtract 100 from both sides.
\(100+b^2-100=676-100\) \(b^2=576\)Step 3: Take square root of both sides.
\(\sqrt{b^2} =\sqrt{576}\) \(b=24\)Therefore, b = 24.

Answers
Answer:
Step-by-step explanation:
75$ for the week

A theater sold 85% of the tickets for a
play. If 170 tickets were sold, how many
tickets were originally put up for sale?
Answers
Answer:
200 tickets.
Step-by-step explanation:
85% = 85/100 = 0.85
170/0.85 = 200
= 200
Check:
200*0.85 = 170
Answer: hope this helps ♡
200 tickets were originally put up for sale.
Step-by-step explanation:
85% = 170
(we divide 85 and 170 by 85)
1% = 2
(now multiply 1 and 2 by 100)
100% = 200
(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)

0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside
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
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.

Show work to find the solution for the system:
y = 3x + 5
12x - 4y = -20
Answers
Answer: Infinitely many solutions
The solutions are of the form (x,y) = (x,3x+5) for any real number x.
========================================================
Explanation:
Plug the first equation into the second. We'll replace y with 3x+5
12x-4y = -20
12x-4( y ) = -20
12x-4(3x+5) = -20 .... y replaced with 3x+5
12x-12x-20 = -20
0x-20 = -20
0-20 = -20
-20 = -20
We end up with a true equation no matter what x is.
Therefore, this system has infinitely many solutions.
Each solution is of the form (x,y) = (x,3x+5) because y = 3x+5.
Answer:
Infinently Many solutions!
Any number would work.
Hope this helps! :)

Determine the number of solutions to the system of linear equations shown on the graph.
coordinate plane with one line that passes through the points 0 comma 2 and 1 comma 0 and another line that passes through the points 0 comma negative 1 and 1 comma negative 2
Answers
This answer was generated by an AI and may be incorrect.
The number of solutions to a system of linear equations can be determined by finding the point where the lines intersect. If the lines intersect at exactly one point, the system has a unique solution. If the lines are coincident, the system has infinitely many solutions. If the lines are parallel, the system has no solution.
From the graph, we can see that the two lines intersect at exactly one point, which means that the system of linear equations has a unique solution.
That is where both lines intersect, therefore that is the solution.

Answers
Answer:
The solution of given equation is (2,5)
Step-by-step explanation:
The equations give to us are:
y - 3 = x
or
y = x + 3
y = x² - 6x + 13
We can find the solution of the given system of equations by substituting each point in both of the equations. The point which satisfies both of the equation will be the solution of the the system of given equation.
Substitute (2,5) in both equations
y = x+3
5 = 2+3
5 = 5
TRUE
y = x² - 6x + 13
5 = 2² -6(2) + 13
5 = 5
TRUE
Similarly, we can also check the rest of the points, which come as FALSE.
Therefore, the solution of given equation is (2,5)
