The number of persons that can use the room at the same time is 36.
The volume of the cuboid = length x width x height
The room is a cuboid.
Volume of the room = length x width x height
L = 10m, W = 6m, Height = 3m.
Volume = 10 x 6 x 3 = 180 cubic meter.
If each person takes 5 cubic meter of air space,
Then the total person who can occupy the room at the same time is 180/5 = 36.
A cuboid is a three-dimensional geometric shape that is bounded by six rectangular faces, where each face is a parallelogram. It is also known as a rectangular prism. The faces of a cuboid are called its base and lateral faces. The base of a cuboid is the top and bottom rectangular faces, while the lateral faces are the four rectangular faces that connect the base.
Cuboids have eight vertices or corners, where three edges meet, and 12 edges, which are the straight lines that connect the vertices. The length, width, and height of a cuboid are the dimensions of the three pairs of parallel sides of its rectangular faces, and these measurements are usually denoted by l, w, and h, respectively.

A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An item priced at $150 has a fee of $9. If you return an item that has an original price of $180, how much is the restocking fee?
An item priced at $200 has a fee of $12. An item priced at $150 has a fee of $9. The restocking fee for an item priced at $180 is $10.
To solve this problem, we need to use a proportion to relate the item price to the restocking fee. The problem provides two pairs of corresponding item prices and restocking fees: $200 and $12, and $150 and $9. We can set up a proportion using these pairs:
$200/$12 = $150/$9
We can simplify this proportion by dividing both sides by 3:
$200/$4 = $150/$3
Now we can use the simplified proportion to find the restocking fee for an item priced at $180. We'll use cross-multiplication:
$200 x $3 = $150 x $4
$600 = $600
This tells us that the ratios are equivalent, and the restocking fee for an item priced at $180 is $10.
In other words, the restocking fee is proportional to the item price, and we can use the given pairs of prices and fees to find the fee for any given price using a proportion.

suppose there are three cards, a, b, and c. two of them will be drawn one by one with replacements. what is the probability of getting (a, b), i.e. the first card is a and the second card is b?
the probability of getting (a, b), i.e. the first card is a and the second card is b is 2/3 by conditional probability.
The potential of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is computed by dividing the likelihood of the earlier occurrence by the likelihood of the subsequent, or conditional, event.
This is where the independent event and dependent event notion is used. Consider a student who misses class twice each week, omitting Sunday. What are the possibilities that he will take a leave of absence on Saturday of the same week if it is known that he will be absent from school on Tuesday? It has been noted that situations where the outcome of one event influences the outcome of a subsequent event are termed as conditional probability
We can work this out directly from the definition of conditional probability,
[tex]P(G_1|G_2)=P(G_1nG_2)/(P(G_1)[/tex]
Exactly one of the three cards has sides, so
P(G1∩G2)=1/3

(b) what is the probability that none of the student pilots successfully lands the plane using the simulator? (c) what is the probability that exactly eight of the student pilots successfully land the plane using the simulator?
(a) The probability that all the student pilots successfully land the plane using the simulator is 43%
(b) The probability that none of the student pilots successfully lands the plane using the simulator is 0.0026%
(c) The probability that exactly eight of the student pilots successfully land the plane using the simulator is 30.1%
Probability is a measure of the likelihood of an event occurring.
(a) What is the probability that all the student pilots successfully land the plane using the simulator?
Probability of all pilots successfully landing
=> 0.80 x 0.80 x 0.80 x 0.80 x 0.80 x 0.80 x 0.80 x 0.80 x 0.80 = 0.43 or 43%
So, the probability that all the student pilots successfully land the plane using the simulator is 0.43 or 43%.
(b) What is the probability that none of the student pilots successfully land the plane using the simulator?
The probability of each pilot failing to land the plane is 0.20. We can use the multiplication rule again to calculate the probability of none of the pilots successfully landing the plane.
Probability of all pilots failing to land = 0.20 x 0.20 x 0.20 x 0.20 x 0.20 x 0.20 x 0.20 x 0.20 x 0.20 = 0.000026 or 0.0026%
So, the probability that none of the student pilots successfully land the plane using the simulator is 0.0026% or 0.000026.
(c) What is the probability that exactly eight of the student pilots successfully land the plane using the simulator?
where P(X=k) is the probability of k successes, n is the total number of trials, p is the probability of success in one trial, and nCk is the binomial coefficient, which represents the number of ways to choose k successes out of n trials.
In this case, we have n=9, k=8, p=0.80, and (1-p)=0.20. So, the probability of exactly eight pilots successfully landing the plane is:
P(X=8) = 9C8 * 0.80^8 * 0.20^(9-8) = 0.301 or 30.1%
So, the probability that exactly eight of the student pilots successfully land the plane using the simulator is 0.301 or 30.1%.

Can someone help me with this question i dont get it
Answer:
Step-by-step explanation:
The equation connects m and n.
Suppose n=1,
m=3/1=3.
If n=2,
m=3/2=1.5
If n=3,
m=3/3=1. This shows that as n increases, m decreases.
If m was equal to 1,
1=3/n
Thus n=3.
If m=2,
2=3/n
n=1.5
If m=3,
3=3/n
n=1.
This also shows that as m increases, n decreases.
Hope this helps :)
Answer:
When I increased n, m decreased.
When I increase m, n decreases
Step-by-step explanation:
Let's say that m is one and n is 3
1 = [tex]\frac{3}{3}[/tex] Us this as our base to compare increasing m and n.
Increase n to 6
[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{6}[/tex]
When I increased n, m decreased.
Increase m to 3
3 = [tex]\frac{3}{1}[/tex]
When I increase m, n decreases
Suppose that a motorboat is moving at ​ft/s when its motor suddenly​ quits, and that s later the boat has slowed to ​ft/s. assume that the resistance it encounters while coasting is proportional to its​ velocity, so that ​dv/dtkv. How far will the boat coast in​ all?
the boat will coast for a distance of 400 ln(2) ft, which is approximately 277.3 ft.
To find how far the boat will coast, we need to use the concept of differential equations. The equation that describes the velocity of the boat at any time "t" after its motor quits is given by:
dv/dt = -k*v
where "v" is the velocity of the boat at time "t", "k" is the proportionality constant, and the negative sign indicates that the velocity is decreasing with time.
We can solve this differential equation to obtain the velocity of the boat as a function of time:
v(t) = v(0) * e^(-k*t)
where "v(0)" is the initial velocity of the boat (40 ft/sec).
Using the given information, we can set up two equations:
v(10) = 20 (velocity after 10 sec)
v(0) = 40 (initial velocity)
Plugging these values into the equation, we get:
20 = 40 * e^(-10k)
Solving for "k", we get:
k = ln(2)/10
Now, we can integrate the velocity equation to find the distance the boat travels during the coasting period:
d = [tex]\int\limits^{\infty}_{10} {v(t)} \, dt[/tex]
Plugging in the values, we get:
d = (40/k) * [e^(-k*10) - 0] = 400 ln(2) ft
To explain the solution, we used the concept of differential equations to model the motion of the boat as it coasts after its motor quits. We used the given information to solve for the proportionality constant "k", which allowed us to find the velocity of the boat at any time.
Finally, we integrated the velocity equation to find the distance the boat travels during the coasting period. The key to this problem was using the concept of differential equations to model the motion of the boat and setting up the appropriate equations to solve for the unknowns.

for the histogram on the right determine whether the mean is greater​ than, less​ than, or approximately equal to the median. justify your answer.
The median exceeds the mean by more. The histogram is skewed to the right, which shows that lower values are dragging down the mean.
The median of the histogram on the right is higher than the mean. This is evident from the histogram's form, which is tilted to the right. This shows that the lower values tend to drag the mean down. The median is greater than the mean. The right-handed skewness of the histogram indicates that the mean is being pulled down by lesser values and However, because it is the centre number and is only impacted by the higher and lower values equally, the median is unaffected by the lower values. Because of this, the mean in this histogram is less than the median.

Answer:
Let's call the length of side 1 "x". Then, the length of side 2 is 2x, and the length of side 3 is x + 4. So, the expression for the three sides of the triangle can be represented as:
x + 2x + (x + 4) = 3x + 4
This expression represents the sum of the lengths of all three sides of the triangle.
Step-by-step explanation:
Answer: x+2x+(4+x)

How will the graph of this function change if the per car charge is changed
to $20 per car?
O
The line will shift vertically down by $5.
O The line will shift vertically up by $5.
O The line will shift horizontally left by $5.
O The line will shift horizontally right by $5.
Answer:
The graph of the function will shift vertically up by $5.
Step-by-step explanation:
The original function is m(x) = 2x + 15, where x is the number of people in the car. If the per car charge is changed to $20 per car, the new function becomes m(x) = 2x + 20, because the charge per car has increased by $5.
This means that the y-intercept of the new function is 20 instead of 15, which represents the minimum cost for a car, regardless of the number of people inside. So the graph of the new function will be shifted vertically up by $5 from the graph of the original function.

The Lupines, a family of werewolves, are heading off for a vacation in the woods of Transylvania. Uncle Harry Lupine has rented a total of 12 horror movie videos and gory games on CDs to amuse the kids, Freddy and Lenore, on the trip. The kids want to know how many games and movies they have. Uncle Harry wants Freddy and Lenore to do some math on the trip, so he tells them, "Games rent for $4. 50 each and movies for $3. 99 each. The total was $49. 92 before tax. Now you can figure out the answer. "
Uncle Harry rented 4 games, and using that he also rented 8 movies.Therefore, the Lupine family has 8 horror movies and 4 gory games for their vacation.
What is word problem?
A word problem is a type of mathematical problem that is presented using words instead of or in addition to mathematical symbols and equations. Word problems often describe a real-world scenario or situation, and they require the solver to use math skills and critical thinking to identify the relevant information, determine the mathematical operation or operations required, and arrive at a solution to the problem.
Let's assume that the number of movies Uncle Harry rented is "m" and the number of games is "g". We want to find the values of "m" and "g".
From the problem statement, we know that:
The total number of movies and games rented is 12: m + g = 12
The cost of each movie is $3.99: 3.99m
The cost of each game is $4.50: 4.5g
The total cost before tax is $49.92: 3.99m + 4.5g = 49.92
We can use the first equation to express "m" in terms of "g":
m = 12 - g
Substituting this expression for "m" in the second equation, we get:
3.99(12 - g) + 4.5g = 49.92
Expanding the brackets and simplifying, we get:
47.88 - 3.99g + 4.5g = 49.92
0.51g = 2.04

one card is randomly selected from a standard deck of 52 cards. what is the probability of randomly selecting a(n) jack or 4? enter your answer as a reduced fraction.
the probability of randomly selecting a jack or 4 from a standard deck of 52 cards is 2/13.
In a standard deck of 52 cards, there are four jacks and four 4s, for a total of 8 cards that are either a jack or a 4. The probability of selecting a jack or 4 can be found by dividing the number of favorable outcomes (8) by the total number of possible outcomes (52): P(jack or 4) = 8/52. This fraction can be reduced by dividing both the numerator and denominator by 4: P(jack or 4) = 2/13. Therefore, the probability of randomly selecting a jack or 4 from a standard deck of 52 cards is 2/13. Probability is a measure of the likelihood of an event occurring, expressed as a number between 0 and 1. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in a wide range of fields, from gambling and sports to scientific research and data analysis. Understanding probability is important for making informed decisions, predicting outcomes, and assessing risks.
