Answers

The number of peaks, symmetry, tendency to skew, and homogeneity of a distribution are all indicators of its shape.

Explain about the shape of the distribution?

There are two types of data item distributions: symmetric and asymmetric. The "normal distribution" and the "skewed distribution" are two prevalent illustrations of both symmetry and asymmetry. The distribution's two halves are mirror images of one another in a symmetrical distribution.

The number of peaks, the presence of symmetry, the propensity to skew, and the homogeneity of a distribution all help to explain its shape. (Graphs with skewed distributions show a greater number of points on one side than the other.) PEAKS: Graphs frequently show maximums or peaks in a certain area.

Either a normal distribution or a normal curve. When dealing with such a distribution, the mean should be reported.

Simple Frequency Distribution:

A simple frequency distribution is a table that lists each unique score in the data set and the number of times that score appears.

Score Frequency:

1.0 3

1.1 3

1.2 1

1.3 1

1.5 1

2.0 1

2.2 2

2.3 2

2.5 1

3.0 2

3.2 1

3.4 2

3.5 2

3.7 1

3.8 1

4.0 5

Grouped Frequency Distribution:

A grouped frequency distribution is a table that groups the scores into ranges (also known as bins) and lists the number of scores that fall into each range.

Score Range Frequency

1.0-1.9 9

2.0-2.9 7

3.0-3.9 10

4.0-4.9 4

Frequency Polygon:

A frequency polygon is a graph that is created by connecting the midpoints of the top of the bars in a histogram. The x-axis represents the scores and the y-axis represents the frequency.

Histogram:

A histogram is a graph that represents the frequency distribution of a set of continuous data. It is similar to a bar graph, but the bars are adjacent to each other and there are no spaces between the bars.

Shape of the distribution:

The shape of the distribution is right-skewed, which means that the majority of the data is concentrated on the left side of the distribution and there is a long tail of data points on the right side. This is indicated by the fact that the majority of the scores are between 1 and 3, while only a few scores are at 4.0 or above.

What are trigonometric functions?

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given that, A boat is heading towards a lighthouse, whose beacon-light is 111 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 6°, before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 13°

tan 6° = 111/base

base = 1056

tan 13°= 111/base-AB

base - AB = 480.79

AB = 575.21

Hence, the distance between A and B is 575.21

Question 2 0 / 1 pts In Old English (OE), endian-endode-endod (end/ended/ended in ModE) is an example of a form of verb inflection. base

Answers

In Old English (OE), endian-endode-endod (end/ended/ended in ModE) is an example of a base form of verb inflection.

The base form of the verb "end" in Old English is "endian." This form is used as the root or base form from which other forms of the verb are derived. In this case, "endian" is inflected to "endode" to indicate a past participle form, and to "endod" to indicate a simple past form.

This is an example of a base form of verb inflection, where the base form of a verb is altered to indicate tense, aspect, or voice. This type of inflection is common in older languages like Old English, but has since declined in use in modern English, where auxiliary verbs and word order are used to convey tense and aspect.

Now, According to the question:

"Information available from the question"

Let a be a 3 x 2 matrix. explain why the equation a x b cannot be consistent for all b in.

Since a 3x2 matrix only has 2 columns, matrix A can at most have 2 pivot columns and 2 pivot positions. This cannot fill all 3 rows w/ pivots so Ax=b can't be consistent for all b in R3. If A is an m x n matrix w/ m>n then A can have at most n pivot positions which isn't enough to fill all m rows, so Ax = b can't be consistent for all b in R3.

prove there's always a real number greater than 0 for which the reciprocal of a natural number is less than it

Answers

Suppose the real number x is greater than 0. Then for any natural number n, the reciprocal of n, 1/n, is less than x if and only if n > 1/x.

Since 1/x is a positive real number, it is always less than a sufficiently large natural number, say N. Hence, 1/N < x.

Therefore, there exists a natural number for which the reciprocal is less than x.

Proof: Reciprocal of N Less Than X

The solution is based on the properties of real numbers and the notion that there is always a natural number greater than any positive real number.

For a given positive real number x, if we take a natural number n that is larger than 1/x, then the reciprocal of n, 1/n, will be less than x. This is because 1/n = n^(-1), which means the value of n^(-1) becomes smaller as n increases.

So, if we choose a sufficiently large natural number, its reciprocal will always be less than any positive real number x. This means that for any positive real number x, there is always a real number greater than 0 (1/n) for which the reciprocal of a natural number (n) is less than it (x).

Answers

The length of each piece of yarn in mixed fraction form if total length is 18 feet, is 2(4/7) feet each for 7 pieces.

What is fraction?

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

The number of pieces of yarn Cody has = 3

Length of 1 piece of yarn = 6 feet

The number of pieces Cody needs to cut is = 7

The total length of yarn = Number of pieces of yarn × Length of 1 piece of yarn

Apply the arithmetic operation of multiplication.

Substitute the values into the equation -

The total length of yarn = 3 × 6

The total length of yarn = 18 feet

The length of each yarn piece = Total length of yarn / Number of pieces Cody needs to cut

Apply the arithmetic operation of division.

Substitute the values into the equation -

The length of each yarn piece = 18 / 7

The result is obtained in a fractional form -

The length of each yarn piece = 2(4/7)

Therefore, the length of each piece is 2(4/7) feet.

What do you mean by probability?

Probability is a branch of mathematics that deals with the likelihood or chance of an event happening. It is a number between 0 and 1 that indicates the likelihood of an event occurring, with 0 meaning that an event is impossible and 1 meaning that an event is certain to occur.

Probability is used to model and make predictions about real-world situations such as the outcome of a coin flip, the results of a survey, or the success of a marketing campaign. It is also used in many fields including statistics, finance, engineering, and sciences to make decisions based on uncertain data.

The problem requires the use of the normal approximation to the binomial distribution to estimate the probabilities. Let X be the number of flights that arrive on time out of 186 flights. Then X follows a binomial distribution with parameters n = 186 and p = 0.88.

We can use the normal approximation to estimate the probability of X taking different values. Let's denote the mean and standard deviation of X as mu and sigma respectively:

mu = np = 186 × 0.88 = 163.68

sigma = √(np(1-p)) = √(186 × 0.88 × 0.12) = 5.55

(a) P(159) = P(X = 159) can be estimated using the normal distribution using the Z-score:

Z = (159 - mu) / sigma = (159 - 163.68) / 5.55 = -0.77

P(159) ≈ P(Z < -0.77) ≈ 0.2224 (using a standard normal table)

(b) P(X ≥ 159) can be estimated using the cumulative distribution function:

Z = (159 - mu) / sigma = (159 - 163.68) / 5.55 = -0.77

P(X ≥ 159) = P(Z ≥ -0.77) = 1 - P(Z < -0.77) = 1 - 0.2224 = 0.7776

Z = (161 - mu) / sigma = (161 - 163.68) / 5.55 = -0.36

P(X < 161) = P(Z < -0.36) = 0.3545 (using a standard normal table)

(d) P(161 ≤ X ≤ 174) can be estimated using the cumulative distribution function:

Z1 = (161 - mu) / sigma = (161 - 163.68) / 5.55 = -0.36

Z2 = (174 - mu) / sigma = (174 - 163.68) / 5.55 = 1.51

P(161 ≤ X ≤ 174) = P(Z1 < Z < Z2) = P(Z < 1.51) - P(Z < -0.36) = 0.9330 - 0.3545 = 0.5785
