Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.

Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answers
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

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.

Answer:

Step-by-step explanation:
So we can break this figure into 2 shapes. A rectangle and a right triangle.
Once we do that, we can solve the area for each shape.
Rectangle: 6 x 3 = 18
For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.
Triangle: (12 x 15)/2 = 90
We can then add our two answers up to get our final answer.
18 + 90 = 108

A car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. During week 3 of the recall, the manufacturer fixed 391 cars. In week 13, the manufacturer fixed 361 cars. Assume that the reduction in the number of cars each week is linear. Write an equation in function form to show the number of cars seen each week by the mechanic.
f(x) = 3x + 400
f(x) = 3x + 391
f(x) = −3x + 391
f(x) = −3x + 400
please explain ;-;
Answers
Answer:
f(x) = -3x + 400.
Step-by-step explanation:
To write the equation in function form to represent the number of cars seen each week by the mechanic, we need to consider the given information.
Let's define:
x: the number of weeks since the start of the recall.
Given that the reduction in the number of cars each week is linear, we can determine the equation by considering the initial number of cars fixed and the reduction rate.
In week 3, the manufacturer fixed 391 cars, which indicates that in the third week (x = 3), the number of cars fixed is 391. This gives us a reference point.
Now, we can find the equation in the form f(x) = mx + b, where m represents the slope (reduction rate) and b represents the initial value (number of cars fixed in the starting week).
To find the slope (m):
We need to determine the change in the number of cars fixed from week 3 (x = 3) to week 13 (x = 13).
The change in x is 13 - 3 = 10.
The change in the number of cars fixed is 361 - 391 = -30.
The slope (m) represents the rate of change, so we calculate it as:
m = (change in the number of cars fixed) / (change in x) = -30 / 10 = -3
Now, we have the slope (m = -3).
To find the initial value (b), we substitute the values of x and f(x) into the equation:
f(3) = 391
Plugging in the values:
-3(3) + b = 391
Simplifying the equation:
-9 + b = 391
Solving for b:
b = 391 + 9 = 400
Now, we have the slope (m = -3) and the initial value (b = 400).
Therefore, the equation representing the number of cars seen each week by the mechanic is:
f(x) = -3x + 400

The same art teacher estimates that he has enough clay for 9 students. Is he correct? Why?
Remember: He has 47 1/3 pounds of clay and wants to give each student 2 1/2 lbs of clay.
*Use compatible numbers to estimate. These are numbers that are close to the actual numbers that you know will divide easily.
Answers
Answer:
The art teacher is incorrect.
Step-by-step explanation:
Coming Up with Compatible Estimate Numbers:
The teacher has 47 1/3 pounds of clay. We can round this to 50. Now we have 50 pounds of clay.
Explaining the Operations:
The teacher wanted to distribute the clay by 2.5 lbs. This means we need to divide the amount of clay by 2.5.
Performing the Operations:
Divide 50 by 2.5 ---> 50÷2.5=(5÷2.5)*10--->5÷2.5=2--->2*10=20
Final Conclusion
For every student, the art teacher plans to give 2.5 lbs of clay. This means he will divide his 47 1/3 pounds by 2.5 piles and hand them out to the students. If we round 47 1/3 to 50 (about 2 points higher) and divide 50 by 2.5, you get 20. This means he would have a little less than enough clay for 20 students, not 9. Therefore, the art teacher is incorrect.
****ANOTHER POSSIBLE SOLUTION****
You can also multiply 9 x 2.5 and see if the product is close to 47 1/3. In this case, you can round 2.5 to 3 and proceed with the multiplication. 9*3=27 Since 27 is a lot lower than 47 1/3, the art teacher is incorrect.

6 + 6x → 6(1 + x)
6(x - 1) → 6x - 6
Step-by-step explanation:
What you do is use the distributive property on them. let's take the first one as an example. 6x + 18 = 6(x+3)
The distributive property bascially means that you multiply whatever number outside the parenthesis by what's inside of the parenthesis.
SO 6 · x = 6x and 6 · 3 = 18, all together, that equals 6x + 18. See how I distributed the 6 to both the number and the variable?
