A man is trying to zombie-proof his house. He wants to cut a length of wood that will brace a door against a wall. The wall is 4 feet away from the door, and he wants the brace to rest 2 feet up the door. About how long should he cut the brace?
Answers
Answer:
Assuming you're rounding to the nearest tenth, he should cut the brace 4.5 feet long.
Step-by-step explanation:
Since this is a right triangle, you can use the a^2 + b^2 = c^2 easily.
You can use either 2 or 4 as the a or the b.
After filling in the equation, 2^2 + 4^2 = c^2, you can calculate it to find it is 4 + 16 = c^2.
If you add 16 + 4, you get 20. So now, you need to find the square root of 20 which is 4.4721 but if you round to the nearest tenth, you get 4.5^2.
He should cut the brace to 4.5 square feet.
I hope this helps :))

b. There are 1,000,000 kiloliters in a milliliter.
c. There are 1,000 milliliters in a kiloliter.
d. There are 1,000 milliliters in a kiloliter.
Answers
The correct statement is a. There are 1,000,000 milliliters in a kiloliter.
A kiloliter is a unit of volume equal to 1,000 liters. One liter is equal to 1,000 milliliters. Therefore, one kiloliter is equal to 1,000 x 1,000 = 1,000,000 milliliters.

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.

Rate of change: The rate of change is another word for slope, or rise/run, so we can see, from point (0,1), that the rise is 2 units up and 3 units to the right to another point where the line crosses a whole number point.

1 + 72/y = 10,
Answers
Answer:
1. y = 7
2. y = 6
3. y = 7/2
4. y = 8
Step-by-step explanation:
I searched it up and found the answer.
Let's solve each equation one by one :
7y + 7 = 56➝ 7y + 7 = 56
➝ 7y = 56 - 7
➝ 7y = 49
➝ y = 49 / 7
➝ y = 7
42 - 6y = 6➝ 42 - 6y = 6
➝ - 6y = 6 - 42
➝ - 6y = - 36
➝ y = -36 / - 6
➝ y = 6
( y + 1 )² = 9➝ ( y + 1 )² = 9
➝ y + 1 = √ 9
➝ y + 1 = 3
➝ y = 3 - 1
➝ y = 2
1 + 72 / y = 10➝ 1 + 72 / y = 10
➝ 72 / y = 10 - 1
➝ 72 / y = 9
➝ 72 = 9y
➝ 9y = 72
➝ y = 72 / 9
➝ y = 8
The graph of y = f(x) is shown in the attached image.
For each point (a,b) that is on the graph of y = f(x), the point (2a +1, 3b) is plotted, forming the graph of another function y = g(x). As an example, the point (0,2) lies on the graph of y = f(x), so the point (2*0 + 1, 3*2) = (1, 6) lies on the graph of y = g(x).
I need help expressing g(x) in terms of x and describing the transformations that can be applied to the graph of y = f(x) to obtain the graph of y = g(x). I would like an explanation.
Answers
The calculated expression of function g(x) in terms of x is g(x) = 3f((x-1)/2)
Expressing the function g(x) in form of xTo express g(x) in terms of x, we need to use the relationship given between the points on the graph of y=f(x) and the corresponding points on the graph of y=g(x).
Specifically, if a point (a,b) is on the graph of y=f(x), then the point (2a+1,3b) is on the graph of y=g(x).
Using this relationship, we can write:
g(x) = 3f((x-1)/2)

Answers
Answer: The range is C, 25.
Explanation: The greatest number is the last stem and the last leaf on the chart. In this case, the largest number is 35. To find the range, subtract the smallest number from the largest number. This difference will give you the range.
the Range of the given stem and leaf plot is 25.
What is the stem-and-leaf plot?A stem and leaf is a table used to display data. The 'stem' on the left displays the first digit or digits. The 'leaf' is on the right and displays the last digit.
Given, a Stem and leaf plot
The greatest number is the last stem and the last leaf on the chart. In this case, the largest number is 35. To find the range, subtract the smallest number from the largest number. This difference will give you the range.
A stem-and-leaf plot works so that the number in the leaf column is the one place of the beginning of the number in the stem column. So the numbers you actually have in this set are 10,12,12,22,23,24,30, and 35. The range is 35-10, so 25.
Therefore, the Range of the given stem and leaf plot is 25.
