The proportion of people who speak English and isiXhosa only is 0.031 (C).

The most widely spoken language is isiZulu (d).

To find the proportion of people who speak English and isiXhosa only, we need to consider the number of people who speak English and isiXhosa only (highlighted in the diagram) divided by the total number of people. Looking at the diagram, we see that the number of people who speak English and isiXhosa only is 50, and the total number of people is 1,600. Therefore, the proportion is\(50/1,600 = 0.031\), which corresponds to option (C).

To determine the most widely spoken language, we need to identify the language with the highest number of speakers. Looking at the diagram, we can see that the language with the highest number is isiZulu, represented by the square at the bottom left, which has a count of 900. Therefore, the most widely spoken language is isiZulu, corresponding to option (d).

Profit = revenue - total cost

cost is total expenses incurred in running the business

total cost =  cost of rent and the expensive saws and equipment + cost of wood + amount paid to worker

50 + 30 + 10 = 90

revenue is the amount earned from selling the chairs. it is equal to 150

Profit = 150 - 90 = 60

Answer:

The relationship between altitude and atmospheric pressure is exponential, as shown by the function f(x) in this problem.

Step-by-step explanation:

a. To find the pressure at sea level, we need to evaluate f(x) at x=0:
f(0) = 1038(1.000134)^0 = 1038 millibars.

Therefore, the pressure at sea level is approximately 1038 millibars.

b. To find the atmospheric pressure at an altitude of 2000 meters, we need to evaluate f(x) at x=2000:
f(2000) = 1038(1.000134)^(-2000) ≈ 808.5 millibars.

Therefore, the approximate atmospheric pressure at the McDonald Observatory in Texas is 808.5 millibars.

c. As altitude increases, atmospheric pressure decreases. This is because the atmosphere becomes less dense at higher altitudes, so there are fewer air molecules exerting pressure.

If the perimeter of a rectangular living room is 38 meters, the length of the living room is 105 meters.

The perimeter of a rectangle is the sum of the lengths of all its sides. Let's denote the length of the living room as "L". The formula for the perimeter of a rectangle is:

Perimeter = 2(length + width)

We know that the width of the living room is 9 meters, and the perimeter is 38 meters. Substituting these values in the formula, we get:

38 = 2(L + 9)

Dividing both sides by 2, we get:

19 = L + 9

Subtracting 9 from both sides, we get:

The probability that X is between 57 and 105 is 0.8914.

Given:

* X is normally distributed with mean=90 and standard deviation=12

* P(57 < X < 105)

Solution:

* Convert the given values to z-scores:

   * z = (X - μ) / σ

   * z = (57 - 90) / 12 = -2.50

   * z = (105 - 90) / 12 = 1.25

* Use the z-table to find the probability:

   * P(Z < -2.50) = 0.0062

   * P(Z < 1.25) = 0.8944

* Add the probabilities to find the total probability:

   * P(57 < X < 105) = 0.0062 + 0.8944 = 0.8914

Therefore, the probability that X is between 57 and 105 is 0.8914.

The type of diagram used to graphically show the relationship between two numerical variables is called a scatter plot.

A scatter plot is a visual representation of data points plotted on a graph, with one variable represented on the x-axis and the other variable represented on the y-axis.

Each data point on the plot corresponds to a pair of values from the two variables being analyzed. The position of each point on the graph indicates the values of both variables, allowing us to examine the relationship between them.

The main purpose of a scatter plot is to visualize the correlation or relationship between the two variables. The pattern formed by the data points on the plot can indicate the direction, strength, and nature of the relationship.

For example, if the points on the scatter plot tend to form a linear pattern, it suggests a linear relationship between the variables. On the other hand, if the points are scattered randomly with no clear pattern, it indicates a weak or no relationship between the variables.

Scatter plots are commonly used in various fields, including statistics, data analysis, and scientific research. They provide a visual way to explore and interpret relationships between variables, identify outliers, detect trends, and assess the strength and direction of associations.

The point on the number line is one-fifth of the way from the point −9 to the point 17 is -3.8.

A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that it corresponds to, such as when graphing a point.

A number line is exactly what it sounds like—a horizontal, straight line with numbers spaced evenly apart throughout its length. Since it's not a ruler, the distance between each number is irrelevant; instead, the numbers on the line specify how it should be used.

Given:

Number line is one-fifth of the way from the point −9 to the point 17.

As, Distance between the given points is  17 - (-9) = 26 units

An unnormalized relation refers to a table in a relational database that contains more than one row. This means that there are duplicate rows in the table, which violates the rules of normalization.

Normalization is a process in database design that aims to eliminate data redundancy and ensure data integrity. It involves breaking down a database into multiple tables and defining relationships between them. By doing so, we can efficiently store and retrieve data while minimizing inconsistencies.

In an unnormalized relation, duplicate rows can lead to various problems. For example, it can result in data inconsistencies, as updating one instance of a row may not reflect changes in other duplicate rows. Additionally, it can cause unnecessary storage and maintenance overhead.

To normalize an unnormalized relation, we need to identify the functional dependencies in the table and create separate tables for related data. This helps organize the data and reduces redundancy.

In summary, an unnormalized relation is a table in a relational database that has duplicate rows. It is important to normalize such relations to ensure data integrity and efficiency.

Explanation:

The given function is

f(x) = x^2 - 2x - 3

The first step is to graph the function. We would substitute values of x into the function and find corresponding values of y or f(x). We have

For x = - 1, y = (- 1)^2 - 2(- 1) - 3 = 1 + 2 - 3 = 0

For x = 0, y = (0)^2 - 2(0) - 3 = 0 + 0 - 3 = - 3

For x = 1, y = (1)^2 - 2(1) - 3 = 1 - 2 - 3 = - 4

option c. (two-thirds, [infinity]) is the correct option

The set-builder notation can also be used to express sets using an interval or an equation. It is common practise for sets with an unlimited number of elements to write and represent their elements in this way. This makes use of a variable (or several) that fit under the group of typical numerical kinds, such as integers, real numbers, and natural numbers.

The roster notation is a convenient way to express sets mathematically. Within the curly braces of the roster form, the elements (or members) of a set are listed in a row. In a roster notation, a comma is used to indicate the separation of every two elements when the set contains more than one element.
