What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

We have two types of fractions.

Proper fraction and improper fraction.

A proper fraction is a fraction whose numerator is less than the denominator.

An improper fraction is a fraction where the numerator is greater than the denominator.

Example:

1/2, 1/3 is a fraction.

3/6, 99/999 is a fraction.

1/4 is a fraction.

We have,

Let's assume that the total number of floors in the skyscraper is "x".

According to the problem, the builder has built 1/6 of the floors.

So the number of floors built by the builder is:

= (1/6)x

The problem also tells us that the builder has built 13 floors.

So we can set up the equation:

(1/6) x = 13

To solve for "x", we can multiply both sides by 6:

x = 78

Therefore,Therefore, The skyscraper will have 78 floors when it is finished.

Answer:

Yes, people that taking part in an experiment are called variables.

There is normally one person called the dependent variable, and the other who is the independent variable.

The statement provided "people taking part in an experiment are called variables" is incorrect.

In an experiment, the individuals or subjects who participate and are observed or manipulated are not referred to as variables. Instead, they are called participants, subjects, or sometimes, respondents, depending on the context of the study.

Variables, on the other hand, are characteristics or properties that can vary or change among the individuals or subjects in the study. Variables can be classified as independent variables, dependent variables, or control variables.

Independent variables are manipulated or controlled by the researcher, while dependent variables are the outcomes or responses that are measured or observed.

Control variables are other factors that are held constant. Therefore, it is important to differentiate between the individuals participating in the experiment and the variables being studied.

Option c) mean may give misleading information if a distribution is skewed.

When a distribution is skewed, the measure of central tendency that may give misleading information is mean. Skewness is a statistical measure that helps determine the distribution's symmetry.

The mode is the value that appears the most frequently in the dataset. The median is the value in the middle of the dataset when it is sorted in numerical order.

The mean is the average of the dataset, which is calculated by summing all the values and then dividing the total by the number of observations. The skewness can be positive or negative, depending on the direction of the long tail of the distribution.

A positive skew occurs when the tail on the right side of the distribution is longer than the tail on the left side. In this case, the mean will be greater than the median, as the tail on the right side pulls the mean in that direction.

Conversely, a negative skew occurs when the tail on the left side of the distribution is longer than the tail on the right side. In this case, the mean will be less than the median, as the tail on the left side pulls the mean in that direction.

Therefore, option c) mean may give misleading information if a distribution is skewed.

Answer:

The probability that a Dutch male is between 173.5 and 191.5 cm is 0.616

or 61.6%

Step-by-step explanation:

Mean = M = 182.5

Standard Deviation = S = 10.3,

We need to find the z values and then calculate the probabilities,

Probability of being lower than 173.5,

P(X < 173.5),

Finding the z value,

z = (x - M)/S

z = (173.5 - 182.5)/10.3

z = -0.87

Then the corresponding value for the area and hence the probability is,

P(X<173.5) = P(z = -0.87) = 0.1922

P(X < 173.5) = 0.1922

Probability of being lower than 191.5,

P(X<191.5)

Finding the z value,

z =(x-M)/S

z = (191.5 - 182.5)/10.3

z = 0.87

Then the corresponding value for the probability is,

P(X < 191.5) = 0.8078

The probability that a Dutch male is between 173.5 and 191.5 cm is,

P(173.5 < X < 191.5) = P(X < 191.5) - P(X < 173.5)

P(173.5 < X < 191.5) = 0.8078 - 0.1922

P(173.5 < X < 191.5) = 0.6156

To 3 decimal places,

P(173.5 < X < 191.5) = 0.616

P(173.5 < X < 191.5) = 61.6%

Answer:

triangle 1st one ABC=abc

The only triple integral that has all constant bounds when written in cylindrical coordinates is the second one, i.e., ∭x2 + y2 dV.

In cylindrical coordinates, a triple integral is given by ∭f(r, θ, z) r dz dr dθ.

To have constant bounds, the limits of integration must not contain any of the variables r, θ, or z. Let's see which of the given triple integrals satisfy this condition.

The given triple integrals are:

a) ∭xyz dVb) ∭x2 + y2 dVc) ∭(2 + cos θ) r dVd) ∭r3 sin2 θ cos θ dV

To determine which of these integrals have all constant bounds, we must express them in cylindrical coordinates.

1) For the first integral, we have xyz = (rcosθ)(rsinθ)(z) = r2cosθsinθz.

Hence, ∭xyz dV = ∫[0,2π]∫[0,R]∫[0,H]r2cosθsinθzdzdrdθ.

The limits of integration depend on all three variables r, θ, and z.

So, this integral doesn't have all constant bounds.

2) The second integral is given by ∭x2 + y2 dV.

In cylindrical coordinates, x2 + y2 = r2, so the integral becomes ∫[0,2π]∫[0,R]∫[0,H]r2 dzdrdθ.

The limits of integration don't contain any of the variables r, θ, or z.

Hence, this integral has all constant bounds.

3) For the third integral, we have (2 + cos θ) r = 2r + rcosθ. Hence, ∭(2 + cos θ) r dV = ∫[0,2π]∫[0,R]∫[0,H](2r + rcosθ)r dzdrdθ.

The limits of integration depend on all three variables r, θ, and z. So, this integral doesn't have all constant bounds.

4) The fourth integral is given by ∭r3 sin2θ cosθ dV. In cylindrical coordinates, sinθ = z/r, so sin2θ = z2/r2.

Also, cosθ doesn't depend on r or z. Hence, the integral becomes ∫[0,2π]∫[0,R]∫[0,H]r3z2cosθ dzdrdθ.

The limits of integration depend on all three variables r, θ, and z. So, this integral doesn't have all constant bounds.

Therefore, the only triple integral that has all constant bounds when written in cylindrical coordinates is the second one, i.e., ∭x2 + y2 dV.

The ratio of the volume of cylinder C to the volume of cylinder D is ∛6:1.

To determine the ratio of the volume of cylinder C to the volume of cylinder D, we need to consider the relationship between the scale factors of the cylinders.

Given that the ratio of the volume of cylinder A to the volume of cylinder B is 5:1, we can infer that the scale factor between A and B is the cubic root of the volume ratio, which is ∛(5/1) = ∛5.

Similarly, the scale factor between cylinder B and cylinder D is 3:1, which implies that the cubic root of the volume ratio is ∛(3/1) = ∛3.

Now, we know that cylinder A is similar to cylinder C with a scale factor of 2:1. This means that the scale factor between A and C is 2:1, and the cubic root of the volume ratio is ∛(2/1) = ∛2.

By combining the scale factors, we can find the ratio of the volume of cylinder C to the volume of cylinder D:

Ratio of C to D = (Ratio of A to C) * (Ratio of B to D)

= ∛2 * ∛3

= ∛(2*3)

The probability of selecting two marbles with the same color is approximately 0.27 or 27%.

To work out the likelihood that the two marbles drawn have similar variety, we can utilize the accompanying advances:

In the first place, we compute the likelihood of drawing a red marble on the principal pick: 12/24 = 1/2.

On the off chance that the main marble drawn is red, there will be 11 red marbles left clinched, out of a sum of 23 marbles. So the likelihood of drawing one more red marble on the subsequent pick is 11/23.

Likewise, in the event that the principal marble drawn is blue, there will be 4 blue marbles left clinched, out of a sum of 23 marbles. So the likelihood of drawing one more blue marble on the subsequent pick is 4/23.

Furthermore, on the off chance that the main marble drawn is yellow, there will be 6 yellow marbles left taken care of, out of a sum of 23 marbles. So the likelihood of drawing one more yellow marble on the subsequent pick is 6/23.

To get the complete likelihood of drawing two marbles of similar variety, we want to add the probabilities of every one of these cases:

(1/2) x (11/23) + (5/24) x (4/23) + (7/24) x (6/23) = 55/138 or roughly 0.398 or 39.8%.

In this way, the likelihood of drawing two marbles of a similar variety is roughly 39.8%.

=====================================

Explanation:

The statement “there exists a function f such that f(x) < 0, f’(x) > 0, and f”(x) < 0 for all x” is false.

To understand why this statement is false, we must first understand what the symbols mean. The symbol f(x) refers to a function of x, and the symbols f’(x) and f”(x) refer to the first and second derivatives of the function, respectively.

The statement is saying that for all x, the function f(x) will be less than 0, the first derivative f’(x) will be greater than 0, and the second derivative f”(x) will be less than 0.

To show that this statement is false, we need to find an example of a function where this is not the case. Let’s consider the function f(x) = x³. At x = 0, this function is equal to 0, and so f(x) < 0 is not true. Additionally, the first derivative at x = 0 is f’(0) = 0, which is not greater than 0. Thus, the statement is false.

We can also show that this statement is false by looking at the graph of the function f(x). A function with the properties given in the statement would have a graph that looks like a “U” shape, with a minimum point at the origin. However, this is not the case for the function f(x) = x³. The graph of this function is a parabola, which does not have the desired shape.
