The median weight is the weight of the sixth student.The coefficient of skewness is zero

The median is the middle value in a set of data when arranged in ascending or descending order. Since there are 10 students, the middle value would be the weight of the 5th and 6th students when the weights are ranked. The 5th student's weight corresponds to the weight just before the median, and the 6th student's weight corresponds to the median itself.

The mean is calculated by summing up all the data values and dividing by the total number of values. It takes into account every data point in the dataset, making use of all available information. This property distinguishes the mean from other measures of central tendency, such as the median or mode, which may not incorporate every data value. The mean is 110, the median is 110, and the mode is 110.

To find the mean, we sum up all the values and divide by the total count: (150 + 110 + 100 + 35 + 60 + 130 + 40 + 140 + 120 + 160 + 110) / 11 = 110. For the median, we arrange the values in ascending order and find the middle value, which is also 110. The mode is the value that appears most frequently, and in this case, it is 110 as well. The standard deviation is larger than the range.

The range is the difference between the largest and smallest values in a dataset. The standard deviation measures the spread or dispersion of the data points around the mean. While the standard deviation can be larger or smaller than the variance (the square of the standard deviation),

Skewness refers to the asymmetry of a distribution. When a distribution is positively skewed, the tail on the right side of the distribution is longer, and the median will be larger than the arithmetic mean.

The coefficient of skewness measures the degree of asymmetry in a distribution. A coefficient of zero indicates that the distribution is perfectly symmetrical, with the same shape on both sides. In this case, since the mean, median, and mode are all equal (250), the distribution is symmetric, resulting in a skewness coefficient of zero.

To determine the event A, we need to identify the even numbers from the sample space of integers divisible by 3 (0, 3, 6, 9, 12, ...). Among these numbers, only 6, 12, 18, 24, and 30 are even. Thus, the event A is composed of these values.

The set or collection of all possible outcomes of an experiment is called the sample space.

The sample space represents the entire range of possible outcomes in an experiment. It includes every possible outcome or result that can occur, encompassing all relevant elements. The sample space is a fundamental concept in probability theory and provides the basis for analyzing and calculating probabilities.

The value of a + b + c + d = 48 if circle Ca is centered at the origin and passes through P (16, 16), while the circle Cb is centered at P and passes through the origin.

Since circle Ca is centered at the origin and passes through (16,16), its equation is x^2 + y^2 = 16^2.

Since circle Cb is centered at (16,16) and passes through the origin, its equation is (x-16)^2 + (y-16)^2 = 16^2.

Let (a,b) and (c,d) be points on Ca and Cb, respectively. Then we have

a^2 + b^2 = 16^2 (from circle Ca)

(c-16)^2 + (d-16)^2 = 16^2 (from circle Cb)

We can solve for c and d in terms of a and b by adding and subtracting the two equations

c = (a^2 + b^2 + 16^2)/32

d = (a^2 + b^2 - 16^2)/32 + 16

Thus, a + b + c + d = a + b + (a^2 + b^2 + 16^2)/32 + (a^2 + b^2 - 16^2)/32 + 16

Simplifying, we get

a + b + c + d = (2a^2 + 2b^2)/32 + 16

Since a^2 + b^2 = 16^2, we have

a + b + c + d = (16^2)/16 + 16 = 32 + 16 = 48

Therefore, a + b + c + d = 48.

Step-by-step explanation:

- 32 +9 – 2x = -12 – 5x

1.Add numbers

-23 - 2x= -12-5x

2.Rearrange terms

-2x - 23 = -12 - 5x

3. Rearrange terms

-2x - 23 = -5x-12

4. Add 23 to both sides of the equation

-2x-23+23= -5x-12+23

5.Simplify

-2x= -5x+11

6.Add 5x to both sides of the equation

-2x+5x=-5x+11+5x

7.Simplify

3x=11

The average difference between the actual wait time and the guess of the same wait time as the previous one is approximately  5.5 minutes.

1. Calculate the difference between each wait time and the previous wait time:

Wait Time 1 - 0 = 0

Wait Time 2 - Wait Time 1 = 8.2 minutes

Wait Time 3 - Wait Time 2 = 4.3 minutes

Wait Time 4 - Wait Time 3 = 5.1 minutes

Wait Time 5 - Wait Time 4 = 6.5 minutes

2. Calculate the average of the differences:

Average Difference = (8.2 + 4.3 + 5.1 + 6.5) / 4 = 5.5 minutes

The average difference between the actual wait time and the guess of the same wait time as the previous one is approximately 4.5 minutes. This means that, on average, if you guess that each wait time will be the same as the previous wait time, it will be 4.5 minutes off from the actual wait time. To calculate this, we compared each wait time, except for the first one, to the previous wait time, and then calculated the average difference between the two. We found that the average difference was  5.5 minutes. This suggests that, if you guess that the wait time will be the same as the previous one, you can expect to be, on average,  5.5 minutes off from the actual time.

\(f(x) = 7x-2\) and        \(g(x) = \frac{x+2}{7}\)

How to solve:

check if the composite functions of f(x) and g(x) are equal to x (this means they are inverses)

f[g(x)] = x

g[f(x)] = x

Step-by-step explanation:

Checking A.

\(f(x) = \frac{5}{x} -2\)

\(g(x) = \frac{x+2}{5}\)

\(f(g(x)) = f(\frac{x+2}{5} ) = \frac{5}{\frac{x+2}{5} } -2\)

This does not equal x, so we know these are not inverses

Checking B.

\(f(x) = 7x-2\)

\(g(x) = \frac{x+2}{7}\)

\(f(g(x)) = f(\frac{x+2}{7} ) = 7(\frac{x+2}{7}) - 2 = x+2-2 = x\)

\(g(f(x)) = g(7x-2) = \frac{7x-2 + 2}{7} = \frac{7x}{7} = x\)

since both f(g(x)) = x and g(f(x)) = x, we can determine that they are inverses of each other.

Step-by-step explanation:

p(x < c) is best described as the area under the cumulative distribution function (cdf), f(x), to the left of c.

In probability theory, the cumulative distribution function (cdf) is a function that provides the probability of a random variable taking on a value less than or equal to a given value. In this case, p(x < c) represents the probability that the random variable x is less than the value c. To find this probability, we look at the area under the cdf, f(x), to the left of c.

The cdf, f(x), is defined as the integral of the probability density function (pdf) of the random variable. The pdf gives the relative likelihood of the random variable taking on a specific value. By integrating the pdf from negative infinity to c, we obtain the area under the curve of the pdf up to the value c, which corresponds to the probability p(x < c).

Therefore, p(x < c) can be interpreted as the area under the cumulative distribution function, f(x), to the left of the value c. It represents the probability that the random variable x is less than c.

Step-by-step explanation:

a) U(X) is a nonzero function that satisfies E[U(X)] = 0, which shows that the family fo(x) = 2 is not complete.

b) U(X) is a nonzero function that satisfies E[U(X)] = 0, which shows that the family N(0,0) is not complete.

A nonzero function is a mathematical function that takes at least one value different from zero within its domain. In other words, there exists at least one input value for which the output value is not equal to zero.

i) To show that the family fo(x) = 2 is not complete, we need to find a nonzero function U(X) such that E[U(X)] = 0 for all e > 0. Let U(X) be defined as:

U(X) = { -1 if -4 < X < 0

1 if 0 < X < 4

0 otherwise

Then, we have:

E[U(X)] = ∫fo(x)U(x)dx = 2 ∫U(x)dx = 2 [∫(-4,0)-1dx + ∫(0,4)1dx] = 2(-4+4) = 0

Thus, U(X) is a nonzero function that satisfies E[U(X)] = 0, which shows that the family fo(x) = 2 is not complete.

ii) To show that the family N(0,0) is not complete, we need to find a nonzero function U(X) such that E[U(X)] = 0 for all e > 0. Let U(X) be defined as:

U(X) = X

Then, we have:

E[U(X)] = E[X] = ∫N(0,0)xdx = 0

Thus, U(X) is a nonzero function that satisfies E[U(X)] = 0, which shows that the family N(0,0) is not complete.

Using the Range Rule of Thumb, the minimum number of usual smokers we can expect to get out of 20 adults is approximately 0.24. This estimation is based on a mean of 3.8 smokers out of 20 adults and assuming a standard deviation of 1.78.

Using the Range Rule of Thumb, the minimum number of usual smokers we can expect to get out of 20 adults can be estimated by:

Minimum = Mean - (Range Rule of Thumb * Standard Deviation)

Given that 19% of the population smoke, the mean number of smokers out of 20 adults would be:

Mean = 20 * 0.19 = 3.8

To calculate the standard deviation, we need to consider the binomial distribution since it involves a binary outcome (smoker or non-smoker) with a known probability (19%). The standard deviation for a binomial distribution is given by the formula:

Standard Deviation = √(n * p * (1 - p))

Substituting the values, we get:

Standard Deviation = √(20 * 0.19 * 0.81) ≈ 1.78

Now, using the Range Rule of Thumb (approximately ±2 standard deviations), we can calculate the minimum number of smokers:

Minimum = 3.8 - (2 * 1.78) ≈ 3.8 - 3.56 ≈ 0.24

Rounding to 2 decimal places, the minimum number of usual smokers we can expect is approximately 0.24.

Answer:

It is not.

Step-by-step explanation:

For XY to be a tangent XY must be perpendicular to radius at point of contact with circle (X).

Perpendicular also means 90° angle between XY and radius.

90° angle means XYZ should be a right angled triangle

Test for right angle triangle: pythagoras theorem.

3.6²+2.7²≠1.8²

Hence not right angled. XY not a tangent.

The Pythagoras theorem is not applicable thus it will not be tangent to the circle Z.

The tangent of a circle is a line that intersects the circle at the periphery of the circle.

If you draw a line that goes through the center to the tangent touching point then it will give you a 90-degree angle.

If XY is tangent to the circle then ∠YXZ = 90° so ΔXYZ will be a right angle triangle.

Apply Pythagoras' theorem,

1.8² ≠ 3.6² + 2.7²

Since it is not satisfied thus angle X will be not 90 degrees thus XY will not tangent to the circle Z.

Hence "Since the Pythagorean theorem does not apply, it will not be tangent to the circle Z".

Selecting raffle tickets from a large bowl is an example of probability sampling without replacement.

Probability sampling is a method of selecting a subset of individuals from a larger population in a way that each individual in the population has a known and non-zero probability of being selected for the sample.

Sampling without replacement means that once an individual is selected for the sample, they are removed from the population and cannot be selected again. This is in contrast to sampling with replacement, where an individual can be selected multiple times for the sample.

In the case of selecting raffle tickets from a large bowl, each ticket has a known and non-zero probability of being selected for the sample, and once a ticket is selected, it is removed from the bowl and cannot be selected again.
