A change in a population that is not related strictly to the size of the population can be described as a change in the demographic makeup of the population. This refers to changes in the characteristics of individuals within the population, such as age, gender, education level, and ethnicity.

For example, if a population experiences an influx of young adults, this would represent a change in the demographic makeup of the population, even if the overall size of the population remains the same.

Other factors that can contribute to a change in the population's makeup include migration patterns, changes in birth rates and mortality rates, and shifts in cultural or social norms. These changes can have significant impacts on a population, affecting everything from economic growth to social dynamics. Understanding demographic changes is therefore critical for policymakers and researchers seeking to address issues such as inequality, public health, and urban planning. By analyzing population trends and anticipating future changes, we can better prepare for the challenges and opportunities that lie ahead.

a. The measure of angle 7 is 47°. It is is a vertical angle to angle 5

b. If the measure of ∠6 is represented by (2x - 5), the equation used to solve for x is 42 + 2x = 180

c. The value of x is 69

Vertically opposite angles are defined as those angles that are opposite one another at a vertex and are formed by the intersection of two straight lines.

Vertical opposite angles are known to be congruent.

From the information given, we have;

a. ∠5 ≅ ∠7, they are vertical angles

Therefore, angles 5 and 7 are congruent to each other.

∠7 = 47°

b. Suppose ∠6 = 2x - 5

To determine the value of x, we have

∠5 + ∠6 = 180

Then, we have the equation as;

47 + 2x - 5 = 180

collect the like terns

2x = 180 - 42

2x = 138

Divide both sides by 2

x = 138 / 2

The measure of ZAFD is 50 degrees.

Based on the given information:

ZCFE is congruent to ZCFA.

mZCFB = 68°.

mZEFD = 62°.

To find the measure of ZAFD, we can use the fact that angles in the same segment of a circle are equal.

Since ZCFE and ZCFA are congruent, angle ZCFE is equal to angle ZCFA.

Therefore, mZCFA = mZCFE.

Now, let's find the measure of angle ZCFE:

mZCFE = mZCFB + mZEFD (Angle Addition Postulate)

mZCFE = 68° + 62°

mZCFE = 130°

Since ZCFA is congruent to ZCFE, we can conclude that mZCFA is also equal to 130°.

Now, to find the measure of ZAFD, we need to consider the angles in the quadrilateral ZAFD.

The sum of the angles in a quadrilateral is always 360°.

mZAFD + mZAFB + mZBFD + mZBFA = 360°

We know that mZAFB and mZBFD are equal to 90° because they are right angles (angle AFB and angle BFD are right angles in the diagram).

Therefore, we can rewrite the equation as:

mZAFD + 90° + 90° + mZBFA = 360°

Simplifying:

mZAFD + 180° + mZBFA = 360°

Rearranging the equation:

mZAFD + mZBFA = 360° - 180°

mZAFD + mZBFA = 180°

We know that mZBFA is equal to mZCFA, which is 130°.

Substituting the known values into the equation:

mZAFD + 130° = 180°

Subtracting 130° from both sides:

mZAFD = 180° - 130°

mZAFD = 50°

Therefore, the measure of ZAFD is 50 degrees.

The quantity 2.67 × 10³ m/s has three significant figures because the digits 2, 6, and 7 are all significant, and the exponent 3, which represents the power of 10, is not considered a significant figure.

Scientists use significant figures to indicate the level of accuracy and precision of a measurement. The significant figures are the reliable digits that are known with certainty, plus one uncertain digit that has been estimated or measured with some degree of uncertainty. In determining the significant figures of a number, the following rules are applied: All non-zero digits are significant.

For example, the number 345 has three significant figures. Zeroes that are in between two significant figures are significant. For example, the number 5004 has four significant figures. Zeroes that are at the beginning of a number are not significant. For example, the number 0.0034 has two significant figures. Zeroes that are at the end of a number and to the right of a decimal point are significant. For example, the number 10.00 has four significant figures.

There are six possible outcomes in the outcomes space. Let us solve each part of the question.How many possible outcomes are there in the outcomes space?The possible outcomes in the outcomes space for the given problem is calculated by multiplying the number of outcomes of the first roll by the number of outcomes of the second roll.Number of possible outcomes of each roll

= 6 (as there are six faces on a dice)Total possible outcomes in the outcomes space

= 6 × 6

= 36So, there are 36 possible outcomes in the outcomes space.How many elements are in the event of getting different numbers without repetitions?In this case, the two rolls are independent. This means the first roll doesn't affect the second roll. Thus, all possible outcomes with different numbers are 6 × 5

= 30. So, there are 30 elements in the event of getting different numbers without repetitions.How many elements are in the event of getting different numbers without repetitions but the second number must be a 4?In this case, we can have any one of the six numbers in the first roll. Then, only one number 4 is left for the second roll. Thus, there are 6 possible outcomes where the second number is a 4. Hence, there are 6 elements in the event of getting different numbers without repetitions but the second number must be a 4.The summary of the results is as follows:How many possible outcomes are there in the outcomes space.- 36 How many elements are in the event of getting different numbers without repetitions. - 30 How many elements are in the event of getting different numbers without repetitions but the second number must be a 4? - 6

An area of mathematics that studies how competing parties interact is known as "game theory."

Game theory analyzes strategic decision-making in situations where multiple participants, known as players, make choices that affect each other's outcomes. It examines the interactions, strategies, and outcomes of these competitive or cooperative situations.

Game theory provides mathematical models and frameworks to analyze various scenarios, such as conflicts, negotiations, auctions, voting systems, and economic markets. It studies the behavior of rational players, their objectives, and the choices they make to maximize their own outcomes, considering the actions and reactions of other players.

The field of game theory explores concepts such as strategies, payoffs, Nash equilibrium, dominant strategies, and cooperative or non-cooperative games. It aims to predict and understand the behavior and outcomes of competitive situations and provides insights into decision-making, resource allocation, and the dynamics of interactions between individuals, organizations, or even nations.

Overall, game theory serves as a valuable tool in various disciplines, including economics, political science, psychology, and computer science, to analyze and model situations where competing parties interact.

On average, the investment account grows by approximately $1,566.81 per year over the 35-year period.

I assume that you mean to ask for the average rate of change of the investment account over a period of 35 years.

To find the average rate of change, we need to calculate the change in the value of the investment account over the given time period and divide it by the duration of the period.

The initial value of the investment account is $5500, and the value after 35 years is given by:

5500(1.064)^35

Using a calculator, this value can be computed as approximately $59,303.39.

Therefore, the change in the value of the investment account over 35 years is:

59303.39 - 5500 = $54,803.39

So, the average rate of change of the investment account over the 35-year period is:

54803.39 / 35 = $1,566.81 per year

Therefore, on average, the investment account grows by approximately $1,566.81 per year over the 35-year period.

Converting feet to inches solve the problem, first we have to convert 20 yards to feet and inches and then calculate the cost per foot and inch. Here are the steps:1 yard = 3 feet (since 1 yard equals 3 feet)20 yards = 20 × 3 = 60 feet (converting yards to feet)1 foot = 12 inches (since 1 foot equals 12 inches)60 feet = 60 × 12 = 720 inches

The total cost of 20 yards of ribbon is $24. Therefore, cost per yard = $24/20 = $1.2We are given that the cost per yard is $0.83. Therefore, we can write:$1.2 = $0.83 × x where x is the cost per foot and inch. To solve for x, we can divide both sides by $0.83:$1.2/$0.83 = xor1.44 = x We can conclude that it will cost $1.44 per foot and inch of the ribbon.
