A histogram would be a better way to represent this data set, as it provides a clear visual representation of the frequency of different values.

A better way to represent the data set would be to use a histogram. A histogram is a graphical representation of a data set that is used to show how frequently certain values occur in the data set. A histogram can be created by first grouping the data into equal intervals, or bins, and then plotting the frequency of each bin on the y-axis of the graph. This allows for easy comparison of the frequency of different values. For example, in the case of the pharmaceutical company’s employee data, one could create a histogram with 5 bins that represent 6-10 months, 11-15 months, 16-20 months, 21-25 months, and 26-30 months. Then, one can plot the number of employees in each bin on the y-axis of the graph. This would provide a clear visual representation of the data set and make it easier to identify any patterns or trends in the data.

The expressions on both sides of the equal sign are examples of the product of two polynomials, and the goal is to simplify these products into the standard form of a single polynomial. To do this, we use the distributive property of multiplication over addition.

Starting with the first expression (5x-3)(8x-4). We use the distributive property to expand the product of two polynomials into a single polynomial:

(5x-3)(8x-4) =

= (5x × 8x) + (5x × -4) + (8x × -3) + (- 4 × -3) =

= 40x² - 20x - 24x + 12 =

= 40x² - 44x + 12 =

= 10x² - 11x + 3.

In a similar manner, the second expression can be expanded and simplified. We use the distributive property to expand the product of two polynomials into a single polynomial:

(2x+8)(7x+6) =

= (2x × 7x) + (2x × 6) + (8 × 7x) + (8 × 6) =

= 14x² + 12x + 56x + 48 =

= 14x² + 68x + 48 =

= 7x² + 38x +24x.

Histogram. is a best choice to display the data.

A histogram is a type of graph that is used to represent the distribution of continuous or discrete data by dividing the data into intervals (bins) and counting the number of data points in each bin.

In a histogram, the bins are represented by bars, and the height of each bar represents the frequency or density of the data within the corresponding interval.

In the case of the salaries of professors, a histogram would be a good choice for displaying the distribution of the salaries because it provides a visual representation of the frequency of different salary ranges and helps to identify any patterns or anomalies in the data.

By dividing the salaries into appropriate intervals, the histogram allows you to see how many professors have salaries within a particular range, and to compare the frequency of different salary ranges.

Answer:

170.25

Step-by-step explanation:

The probability that the committee contains at least one man is 16/21 or 0.7619 or 76.19%.

To find the probability, we divide the number of committees that contain at least one man by the total number of possible committees.

The total number of possible committees is the number of ways to choose 3 people from the 9 total people (6 women and 3 men). This can be calculated using the combination formula C(9,3) = 9! / (3!(9 - 3)!) = 84.

The number of committees that contain at least one man is the number of committees that contain exactly 1 man plus the number of committees that contain exactly 2 men plus the number of committees that contain exactly 3 men.

Exactly 1 man: C(3,1) x C(6,2) = 45

Exactly 2 men: C(3,2) x C(6,1) = 18

Exactly 3 men: C(3,3) = 1

Adding up the results of these three calculations, we find that the number of committees that contain at least one man is

45 + 18 + 1 = 64

probability of having at least one man = 64/84 = 16/21 = 0.7619 = 76.19%

So, the probability that the committee contains at least one man is 16/21 or 0.7619 or 76.19%.

In composition and speech, chronological order is a method of organization in which actions or events are presented as they occur or occurred in time and can also be called time or linear order. Narratives and process analysis essays commonly rely on chronological order.

The x-coordinate is the a) first number of an ordered pair and represents the point's horizontal location.

An ordered pair is a composition of the x coordinate also known as abscissa and the y coordinate also known as ordinate, having two values written in a fixed order within parentheses.

The ordered pair helps to locate a point on the Cartesian plane for better visual comprehension and its numeric values in an ordered pair can be integers or fractions. It is represented as (x, y) Where, x = abscissa, the distance measure of a point from the primary axis “x” and, y = ordinate, the distance measure of a point from the secondary axis “y”

Hence, the x-coordinate is the first number of an ordered pair and represents the point's horizontal location.

In a lottery game where a player picks six numbers and repetition is not allowed, the player has a certain number of choices for each number. The number of choices for each number depends on the range of numbers from which the player can pick.

Let's say the range of numbers from which the player can pick is 1 to 49. For the first number, the player has 49 choices, because they can pick any number from 1 to 49. However, once the player has picked their first number, they have 48 choices for their second number, because they cannot pick the same number again. For the third number, the player has 47 choices, for the fourth number, 46 choices, for the fifth number, 45 choices, and for the sixth number, 44 choices.

The total number of different combinations of six numbers that the player can pick is calculated by multiplying the number of choices for each number. This can be written as 49 x 48 x 47 x 46 x 45 x 44. The total number of combinations is 10,068,347,520.

In other words, if a player picks six numbers from a range of 1 to 49, without repetition, the player has 10,068,347,520 different combinations of numbers to pick from.

It's important to understand that repetition is not allowed in this type of lottery game, as it would greatly increase the number of combinations. Allowing repetition would mean that the player could pick the same number multiple times, which would significantly increase the number of combinations and make the game much less challenging.

In conclusion, in a lottery game where a player picks six numbers from a range of 1 to 49, without repetition, the player has 10,068,347,520 different combinations of numbers to choose from. The number of choices decreases with each number picked, as repetition is not allowed, making the game more challenging.
