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.

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

g = 4

So Uncle Harry rented 4 games, and using the first equation, we find that he also rented 8 movies.

Therefore, the Lupine family has 8 horror movies and 4 gory games for their vacation.

Answer:a is 3:9 B is 6:9

Step-by-step explanation:

Mei concluded that

We are 90% confident that the true proportion of times the die would land on the number 4 is between 0.398 and 0.562. Since this includes 0.5, the die appears to be fair.

It is based on a statistical analysis of the data collected by Mei.

The proportion of times the die landed on the number 4 is calculated as 48/100 = 0.48.

Using a statistical method called a confidence interval, we can estimate the range of values that the true proportion of times the die would land on the number 4 is likely to fall within, with 90% confidence.

The confidence interval calculated for this data is 0.398 to 0.562.

Since this interval includes the value of 0.5  (which would be the proportion of times a fair die would land on the number 4), By using statistical method we cannot reject the hypothesis that the die is fair.

Hence,

By using statistical method, we can conclude that the die would land on the number 4 is between 0.398 and 0.562 as 0.5 the die appears to be fair.

A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females.

This method uses stratified random sampling to help identify its components. Other methods can include random sampling and systematic sampling. A representative sample seeks to choose components that match with key characteristics in the entire population being examined.

Stratified random sampling is a method of sampling that involves the division of a population into smaller subgroups known as strata.

Step-by-step explanation:

At least 174 participants for the clinical trial, with half of them assigned to the current drug group and half assigned to the new drug group.

To answer this question, we need to consider some statistical concepts. The event rate, or the percentage of patients who progress to cancer, is a key factor in this scenario. The current drug has an event rate of 28%, while the new drug is expected to reduce this further to 23%. We want to detect a difference between these two rates, which is 5 percentage points.

The power of a statistical test is the probability of detecting a true difference between two groups, given that such a difference exists. In this case, we want the power to be at least 80%, which means that we want to have an 80% chance of detecting a true difference of 5 percentage points between the current and new drugs.

To calculate the sample size needed for the clinical trial, we need to consider the expected event rates, the desired power, and the level of statistical significance. The level of significance is typically set at 5%, which means that we are willing to accept a 5% chance of making a type I error (i.e., rejecting the null hypothesis when it is actually true).

Assuming a two-sided test (i.e., testing for a difference in both directions), we can use a formula or an online calculator to determine the sample size. The formula is:

n = (Zα/2 + Zβ)² [p₁(1-p₁) + p₂(1-p₂)] / (p₁ - p₂)²

where n is the sample size, Zα/2 is the critical value of the standard normal distribution at the 2.5% level (for a two-sided test), Zβ is the critical value of the standard normal distribution at the desired power (in this case, 80%), p₁ is the event rate for the current drug (28%), p₂ is the event rate for the new drug (23%), and (p₁ - p₂) is the expected difference in event rates.

Plugging in the values, we get:

n = (1.96 + 0.84)² [(0.28)(0.72) + (0.23)(0.77)] / (0.28 - 0.23)²

n = 173.2

Rounding up to the nearest whole number, we get a sample size of 174 participants.

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

The values for the angle B and the side lengths of the right-angled triangle ABC are B = 41°, a = 9.6 , and b = 8.3 using the trigonometric ratios of sine and cosine of angle 49°.

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths. The basic trigonometric ratios includes;

sine, cosine and tangent.

Considering the right-angled triangle ABC, we shall calculate for the angle B and side lengths a and b as follows:

A + B + C = 180° {sum of interior angles of a triangle}

49° + B + 90° = 180°

B = 180° - 139°

B = 41°

sin49 = a/12.7 {opposite/hypotenuse}

a = 12.7 × sin49 {cross multiplication}

a = 9.5848

cos49 = b/12.7 {adjacent/hypotenuse}

b = 12.7 × cos49 {cross multiplication}

b = 8.3319
