(a) Make a histogram of Petal.Length for all 150 observations. Please try a number of different bin-widths and select one that best displays the distribution of the data. Comment on the shape of the histogram. (b) Make a boxplot of Petal.Length for all 150 observations.

The measure of center that best describes each data-set is given as follows:

The median of a data-set is the middle value of a data-set, the value of which 50% of the measures are less than and 50% of the measures are greater than.

The median is usually considered the best measure of center of a data-set, as it is not affected by outliers.

Each of the data-sets in this problem have 7 elements, which is an even cardinality, hence the median is given by the fourth element of the ordered data-set.

The ordered data-set A is given as follows:

0, 0, 1, 2, 2, 3, 4.

The fourth element is of 2, which is the median, and the same procedure is applied for all the other data-sets.

The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.

For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.

Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:

| Value (x) | P(X=x) |

|---|---|

| 0 | 0.2 |

| 3 | 0.2 |

| 4 | 0.3 |

| 5 | 0.2 |

| 6 | 0.1 |

The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

Mean Absolute Deviation (MAD) is a measure of accuracy for a forecasting model.

It measures the average distance between the actual value and the predicted value, and can be calculated using the following formula: MAD = 1/n * Σ |Ai-F i |, where n is the number of data points, Ai is the actual value, and Fi is the forecasted value. MAD is often used to compare the accuracy of different forecasting models. A lower MAD value indicates that the model has a better accuracy in predicting future values. Additionally, MAD can also be used to measure the accuracy of a single forecasting model over time. If MAD increases, then the accuracy of the forecasting model is decreasing.

Taking w as the unknown number, the equation for the given statement is 2(w-8) = 5.

To solve this problem, we need to convert the given statement in mathematical form.

We assume that "w" is the unknown number in the equation.

First, we have to take a closer look at the given statement. It was stated that "twice the different of...  is equal to 5".  It shows that the result of equation 5 is the double value of another equation. We assume the unknown equation as y. Then:

2y = 5

Next, the rest of the statement stated that "a number and 8". From this part of statement, we know that the unknown equation "y" we assume above should be replace with "w-8". Hence:

2(w - 8) = 5

If we want to solve this question, we can solve it by dividing both sides with 2:

2(w - 8) = 5

------------------- : 2

w - 8 = 5/2

The value of the conditional Probability is P(A|B) is 1/3.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The main distinction between a probability and a conditional probability is that a probability is the likelihood of an event, such as A, occurring, whereas a conditional probability assumes that another event, such as B, has already happened in order to define the probability of an event, such as in the conditional probability of A given B.

Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. P(A|B) illustrates it.

By, Conditional Probability :

P (A∩B) =P (A∩B') - P(B)= 4/9 - 1/3 = 1/9

P(A|B) = P (A∩B)/ P(B)

The image of the function after the translation is g(x) = log(x + 1) + 4

In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

here, we have,

f(x)=logx

How to determine the equation of g(x)?

From the graph, the given parameters are:

f(x) = log(x)

From the graph, we can see that:

The graph of f(x) is translated left by 1 unit

The graph of f(x) is translated up by 4 units

This transformation is given as

g(x) = f(x + 1) + 4

Mathematically, this transformation can be represented as

(x, y) = (x + 1, y + 4)

When represented as a function, we have

g(x) = f(x + 1) + 4

Substitute the equation f(x) = log(x)

f(x + 1) = log(x + 1) + 4

So, we have the following equation

g(x) = log(x + 1) + 4

Answer:

the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.

Step-by-step explanation:

To find the distance between two points in a Cartesian coordinate plane, we can use the distance formula:

distance = √((x2-x1)² + (y2-y1)²)

In this case, the two points are (4,-2) and (0,4). So,

x1 = 4, y1 = -2 and x2 = 0, y2 = 4

By substituting these values in the distance formula, we get:

distance = √((0-4)² + (4-(-2))²)

distance = √((-4)² + 6²)

distance = √(16 + 36)

distance = √(52)

So the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.

The prove that the given expression is divisible by 43 is explained below.

A number is said to be divisible by a given number when it leaves no remainder after the division. Example; show that 7^7 is divisible by 49.

7^7 = 823543

So that;

823543/ 49 = 16807

To prove that the expression is divisible by 43, we have;

7^8 = 5764801

7^7 = 823543

7^6 = 117649

Then,

7^8 - 7^7 + 7^6 = 5764801 - 823543 + 117649

                         = 4941258 + 117649

                         = 5058907

Y = 2(x-2)²+2 is the equation used to model the bird's vertex form journey.

A vertex is a point on a polygon where two rays or line segments meet, the sides, or the edges of the object come together. Vertex is the plural form of vertices. For instance, the points A, B, C, D, and E in the aforementioned figures are vertices.

Formula for the general vertex form: f(x) = a(x − h) ² + k

where the vertex is (h,k).

This equation can be used to represent a bird's flight path:

y = 2x² - 8x+10

Answer:The t-intercept of a function is the point at which the function crosses the t-axis. To find the t-intercept of the function A(t) = 14,820 - 247t, we need to find the value of t when A(t) = 0. Setting A(t) = 0 and solving for t, we get:

14,820 - 247t = 0

t = (14820/247)

The t-intercept of the function is 60 months, which means that after 60 months (or 5 years) the amount owed on the car will be $0.

The y-interval of a function is the point at which the function crosses the y-axis. To find the y-intercept of the function A(t) = 14,820 - 247t, we need to find the value of A(t) when t = 0.

At t = 0, A(t) = 14,820 - 247(0) = 14,820.

The y-intercept of the function is $14,820 which means that before making the first payment, the cost of the car including tax and interest is $14,820.
