x=\(\sqrt{15^{2} -12^{2} }\)
x=9 in.
So if we plug in a as 12 and c as 15 we get 144+b^2=225 we then solve to get b^2=81 and so b=9.
In your case, b=x, therefore x=9.

Answers
Answer:
1105.8 in³
Step-by-step explanation:
The surface area is the circumference of the base times the height:
A = 2πrh, which, in this problem, works out to:
A = 2π(4 in)²(11 in) ≈ 1105.8 in³
Answer:
The answer will be 1105.8 in³sq inches.
Step-by-step explanation:
You multiply 4x11 which is the diameter of 44. The the radius with it will be 22. To get the surface, you multiply it= 1105.8 in³

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.

The price of Stock A at 9 A.M. was $15.75. Since then, the price has been increasing at the rate of $0.05 per hour. At noon, the price of Stock B was $16.53. It begins to decrease at a rate of $0.13 per hour. If the stocks continue to increase and decrease at the same rates, in how many hours will the prices of the stocks be the same?
Answers
Answer:
the price of Stock A and Stock B will be the same after 3.5 hours.
Step-by-step explanation:
15.75 + (0.05 × 3) = 15.90
15.90 + 0.05t= 16.53 - 0.13t
0.05t + 0.13t = 16.53 - 15.90
0.18t = 0.63
t = (0.63 ÷ 0.18)
t = 3.5

The largest tree in the world by volume is in Sequoia National Park. The diameter at the base is 36 feet. If a person with outstretched arms can reach 6 feet, how many people would it take to reach around the base of the tree?
Answers
19 people
Step by step explanation
C=pi d
C= 3.14(36)
C= 113.04
113.04 divided by 6 equals 18.84 or 19 people
Answer:
6 people
Step-by-step explanation:
Since it said that the diameter at the base is 36 feet and a person with an outstretched arm would be 6 feet then 6 times 6 is 36 or you can do the division part which will be 36 divided by 6 and you will still get the same answer: 6

There are 10 red, 10 blue, 10 green, and 10 yellow marbles in bag. A student pulled a marble, recorded the color, and placed the marble back in the bag. The table below lists the frequency of each color pulled during the experiment after 40 trials.
Outcome Frequency
red 8
blue 12
green 9
yellow 11
Compare the theoretical probability and experimental probability of pulling a red marble from the bag.
The theoretical probability, P(red), is 20%, and the experimental probability is 25%.
The theoretical probability, P(red), is 25%, and the experimental probability is 20%.
The theoretical probability, P(red), is 50%, and the experimental probability is 20%.
The theoretical probability, P(red), is 25%, and the experimental probability is 8%
Answers
Step-by-step explanation:
The theoretical probability of pulling a red marble from the bag can be calculated by dividing the number of red marbles by the total number of marbles:
P(red) = 10/40 = 1/4 = 0.25 = 25%
The experimental probability of pulling a red marble is the frequency of red marbles pulled divided by the total number of trials:
Experimental probability of pulling a red marble = 8/40 = 0.2 = 20%
Therefore, the theoretical probability of pulling a red marble is 25%, and the experimental probability is 20%.
So the answer is: The theoretical probability, P(red), is 25%, and the experimental probability is 20%.
Please Mark As Brainliest
P(red) = 10/40 = 1/4 = 0.25 = 25%
The experimental probability of pulling a red marble is the frequency of red marbles pulled divided by the total number of trials:
Experimental probability of pulling a red marble =
8/40 = 0.2 = 20%
Therefore, the theoretical probability of pulling a red marble is 25%, and the experimental probability is 20%.
So the answer is: The theoretical probability, P(red), is 25%, and the experimental probability

Answer:
V = 564.15 ft^3
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(pi)(r^2)(h). Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is
V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3

I just got into high school and its been hard for me and i want to do my best to help others. I would ask your teacher for help if you cant find this helpful. It seems kind of hard so i would look at A and you are going to see 4-1 i think thats a really good thing to look for cuz pwn ate 1/4 and its the same so i would go for A. If i got it wrong im so so sorry but i wish you good luck and dont give up you got this
explanation : you would change both fractions to have a common denominator (bottom of the fraction) so 1/4 would equal 3/12 and 1/3 would equal 4/12, so together those would be 7/12 so you would subtract 7/12 from 1, which would be C.
