Answer:
D. 31
Step-by-step explanation:
To find the mean of any group of numbers, you simply add up all the numbers and then divide by how many numbers there are.
Using a calculator or a pencil, add the following:
27 + 28 + 30 +28 + 28 + 31 + 29 + 33 + 28 + 28 + 31 + 33 + 41 + 41 + 25
= 461
The last step is to divide 461 by 15:
461/15 = 30.73
Round 30.73 to the nearest whole number and you get D. 31
A movie theatre offers popcorn in two different containers for the same price. One container is a rectangular prism with a base area of 36in2 and a height of 5in. The other container is a triangular prism with a base area of 32in2 and a height of 6in. Which container is the better deal? EXPLAIN.
Answer: The triangular prism container is a better deal.
Step-by-step explanation:
Hi, to answer this question we have to calculate both containers volume and compare them.
Rectangular prism volume = base area x height
Replacing with the values given:
V = 36 x 5 = 180 cubic inches
Triangular prism volume = base area x height
V = 32 x 6 = 192 cubic inches
The triangular prism container has more volume, so it can hold more popcorn.

Ramona is installing a kitchen counter that is 9 feet by 3 feet.
The counter has a hole in it for a sink that is 2 feet by 3 feet.
What is the area of the kitchen counter?
The area of the kitchen counter is 21 square ft.
Step-by-step explanation:
Area of the sink = 2 x 3
= 6 square ft.
Area of the kitchen counter = 9 x 3 -(6)
=27 - 6
= 21 square ft.
The area of the kitchen counter is 21 square ft.
The area of the kitchen counter is 21 square feet.
To find the area of the kitchen counter, we need to calculate the total area of the counter first and then subtract the area of the hole for the sink.
Calculate the total area of the counter:Therefore, the area of the kitchen counter, after subtracting the sink hole, is 21 square feet.
A plane takes off from City A and goes towards city B at noon. After arriving in city B it has a 5 hour layover before returning. During the return flight the plane runs into a headwind that causes it to go 20 mph slower than the original flight and makes the flight back one more take one extra hour more than the original time. Write an equation that represents the total time traveled with clearly labeled variables
5y² + 2xy – 20x - 100
Step-by-step explanation:
Assume that the distance between City A and City B is x miles,
& the speed of the plane from City A to B is y mph;
The return trip is 20 mph slower so the plane's speed is (y – 20) mph
Since time = distance/speed; The time taken by the plane from City A to B is x / y hrs.
The time taken in return flight is;
x / (y - 20) hrs
The layover was 5hrs long. Therefore the total time taken on the who return trip journey is;
x/y + x/(y-20) + 5
multiply each individual fraction with the LCM of the denominators
x(y-20) + xy + 5 y(y-20)
xy -20x +xy + 5y² – 100
5y² + 2xy – 20x - 100

if a circle has a radius of 2 ft. is the circumfrence and area the same? Explain
Answer:no
Step-by-step explanation:
The circumference and radius are different
The circumference and the area of the circle is same.
Step-by-step explanation:
Given,
The radius (r) of the circle = 2 ft
To find the circumference and the area of the circle.
Formula
The circumference of a circle = 2πr
The area of a circle = πr²
Now,
The circumference of a circle = 2π×2 = 4π
The area of a circle = πr² = π×2² = 4π
Hence,
The circumference and the area of the circle is same.
what is the solution to x^2 = 121?
Answer: {11, -11}
Step-by-step-explanation: To solve for x in this equation, since x is squared, we simply take the square root of both sides of the equation to get x by itself.
It's important to remember however that when taking the square root of both sides of an equation, we always use plus or minus.
In other words in this problem, since x² = 121,
x = + or - 11.
A common mistake is to say that x is just equal to 11. But notice that if you plug a -11 back into the original equation, it also checks.
So our answer to this problem is {11, -11}.
Answer: either 11 or -11
Step-by-step explanation:
you have to square root both sides. Then, you are left with the equation [tex]\sqrt{x^{2} } = \sqrt{121}[/tex]. That means that x either equals to 11 or -11.

The weights of six puppies in ounces are 8, 5, 7, 5, 6, and 9. What is the upper quartile of the data?
Answer:
8
Step-by-step explanation:
the average of 9, 8 , and 7 is 8
The upper quartile for the weights of six puppies, arranged in ascending order and given as 5, 5, 6, 7, 8, 9 ounces, is found by averaging the 4th and 5th points, resulting in 7.5 ounces.
The question seeks to find the upper quartile of the weights of six puppies, which are given in ounces as 8, 5, 7, 5, 6, and 9. To find the upper quartile, step-by-step explanation is necessary. First, we arrange the data in ascending order: 5, 5, 6, 7, 8, 9.
There are 6 data points, so to find the upper quartile (Q3), which divides the top 25% of data from the rest, we identify the data point that falls 3/4th of the way through the dataset. When there are 6 data points, Q3 is calculated by averaging the 4th and 5th data points ((7+8)/2 = 7.5). Therefore, the upper quartile of the data is 7.5 ounces.
Which statements are true about the experimental and theoretical probability of this trial?
Jacob's Coin Flips. Heads occurs 68 times and tails occurs 32 times.
The theoretical probability of landing heads up is less than the experimental probability of landing heads up.
The experimental probability of landing tails up is less than the theoretical probability of landing tails up.
The experimental probability of landing heads up is less than the experimental probability of landing tails up.
The experimental probability of landing heads up is equal to the theoretical probability of landing heads up.
Answer:
the correct answer is A and B
Step-by-step explanation:
i found this by guessing on the question and getting it correct. Also yeet leave five stars and and thanks if u are a swaglord with drip unknown to human kind.
The theoretical probability of landing heads up is less than the experimental probability of landing heads up. Statement 2 is true.
How to calculate the probability?Jacob flipped a coin and got heads 68 times and tails 32 times. The total number of flips is not given, so we cannot determine the exact probability of getting either heads or tails. However, we can make some statements about the experimental and theoretical probability based on the information given.
The theoretical probability of landing heads up is 0.5 or 50%, assuming the coin is fair and has two equally likely outcomes. The experimental probability of landing heads up is 68/(68+32) = 0.68 or 68%, which is greater than the theoretical probability of 50%. Therefore, the statement "The theoretical probability of landing heads up is less than the experimental probability of landing heads up" is false.
The theoretical probability of landing tails up is also 0.5 or 50%, assuming the coin is fair. The experimental probability of landing tails up is 32/(68+32) = 0.32 or 32%, which is less than the theoretical probability of 50%. Therefore, the statement "The experimental probability of landing tails up is less than the theoretical probability of landing tails up" is true.
We cannot compare the experimental probability of landing heads up with the experimental probability of landing tails up without knowing the total number of flips. Therefore, the statement "The experimental probability of landing heads up is less than the experimental probability of landing tails up" may or may not be true.
The experimental probability of landing heads up is 0.68 or 68%, and the theoretical probability of landing heads up is 0.5 or 50%. Therefore, the statement "The experimental probability of landing heads up is equal to the theoretical probability of landing heads up" is false.
In summary, statement 2 is true and statements 1, 3, and 4 are false.

The two way frequency table shows what a group of students did during the summer. Which statement is true related to the table?
Answer:
That statement is true which relates to what activity was taken by most of the students of different categories in that particular group during the summers.
Step-by-step explanation:
A two-way frequency table (likewise called a possibility table) is a valuable instrument for inspecting connections between downright factors. The passages in the cells of a two-way table can be frequency checks or relative frequencies (simply like a single direction table). Two-way frequency tables show what number of information focuses fit in every classification.
Assume you direct a review where you pose every individual two inquiries. When you have wrapped up the overview, you will have two bits of information from every individual. At whatever point you have two bits of information from every individual, you can arrange the information into a two-way frequency table.
