a. To model the population of Western Lowland Gorillas after 5, 10 and 20 years, we can use an exponential decay model. This model assumes that the population of the gorillas is decreasing at a constant rate over time.

Let y equal the population of the gorillas and x represent the number of years since 2022.

The exponential decay model is represented by the equation:

y = a*e^(-rt)

Where a is the initial population, r is the decay rate and t is the number of years.

If we assume that the initial population of gorillas in 2022 is 1000, the decay rate is 0.1, and we can calculate the population of gorillas after 5, 10, and 20 years.

For 5 years after 2022:

y = 1000e^(-0.15) = 810 gorillas

For 10 years after 2022:

y = 1000e^(-0.110) = 648 gorillas

For 20 years after 2022:

y = 1000e^(-0.120) = 404 gorillas

b. Table:

Years Gorilla Population

5            810

10            648

20            404

c. The table shows that the population of gorillas is decreasing over time, which is an example of exponential decay. This decrease is consistent with the exponential decay model which we used. Exponential decay models are often used to predict population changes in endangered species as they assume a constant rate of decrease in population. Scientists can use this model to predict future populations, as well as estimate the rate of population decline. Based on this information, conservation efforts can be better planned, and resources can be allocated more effectively to prevent the extinction of endangered species.

The correct option is option b) subjectively divide the 20 plots into 10 pairs (making the plots within a pair as similar as possible) and then, for each pair, flip a coin to assign the fertilizers to the 2 plots.

A sort of probability called subjective probability is one that is based on a person's subjective assessment or personal knowledge of the likelihood of a particular result. It doesn't use facts or formal computations; instead, it merely includes the subject's ideas and prior experience.

A subjective likelihood varies from person to person and is not based on previous facts or market data. In other words, it is not founded on reality but rather is the result of an individual's opinion.

In the majority of probability theories, quantifiable data is evaluated to ascertain the likelihood of an event occurring. However, subjective probability lacks a formal calculation, is influenced by human ideas, and is not based on quantitative data.

Therefore, The correct option is option b) subjectively divide the 20 plots into 10 pairs (making the plots within a pair as similar as possible) and then, for each pair, flip a coin to assign the fertilizers to the 2 plots.

What is the two-dimensional shape?

Plane figures are two-dimensional figures. Three-dimensional figures are solid shapes.

A cross-section is a shape formed by the intersection of a solid object and a plane. A three-dimensional shape's cross-section is a two-dimensional geometric shape.

Cross-Sectional Shapes

Cross-sections are classified into two types:

* Horizontal cross-sections and

* Vertical cross-sections.

Answer:

∠ IMN = 70°

Step-by-step explanation:

∠ KIM = ∠ JIL ( vertically opposite angles ), that is

x + y = 102 → (1)

∠ IMN = 3x - 26 ( vertically opposite angles ) , that is

y = 3x - 26 ← substitute into (1)

x + 3x - 26 = 102

4x - 26 = 102 ( add 26 to both sides )

4x = 128 ( divide both sides by 4 )

x = 32

Then

∠ IMN = y = 3x - 26 = 3(32) - 26 = 96 - 26 = 70°

On solving the provided question, we can say that from percentage Eli's hot cocoa has more chocolate flavor because his chocolate percentage is higher.

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Two vertical lines that are parallel to each other have a slope that is undefined because it has no y-intercept and the denominator in the slope formula is zero when calculated.

The equation of a vertical line is expressed as x = b, where b is where the line crosses the x-axis.

Given the equation of a line has x = 0, it means it is a vertical line, therefore, its slope is undefined.

The difference quotient of quadratic equation f(x) = 5 · x² - 5 · x - 6 is equal to r = 10 · x + 5 · h.

Herein we have the quadratic equation f(x) = 5 · x² - 5 · x - 6, from which we must determine the difference quotient, defined below as:

r = [f(x + h) - f(x)] / h

Where:

First, substitute on each component of numerator of difference quotient:

f(x) = 5 · x² - 5 · x - 6

f(x + h) = 5 · (x + h)² - 5 · (x + h) - 6

f(x + h) = 5 · (x² + 2 · h · x + h²) - 5 · (x + h) - 6

f(x + h) = 5 · x² + (10 · h + 5) · x + (5 · h² - 6)

Second, substitute on difference quotient:

r = [f(x + h) - f(x)] / h

r = [[5 · x² + (10 · h + 5) · x + (5 · h² - 6)] - (5 · x² - 5 · x - 6)] / h

An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

All three parts of the given problem regarding trails, paths and walks have been solved below.

A path is defined as a way in which we can traverse the graph such that neither vertices nor the edges are repeated. In the given graph we can see that for going from a to c there are 4 ways that satisfy the condition of a path. A Trail is an open walk in which no edge is repeated but the vertex can be repeated. So, in the given graph we can see that there are 3!(4) ways in which we can go from a to b and then c and 4 paths in which we can go directly from a to c.

The walk is a sequence of vertices and edges of a graph that can be closed if we come to the same point after traversing the graph or open if we go from one point to another. In the given graph since we go from a point to c point the walk is open but the length of edges of the walk is not defined so if we take the no. of edge length to be 4

there can be 44 ways

so,

Given here: monetary conversion

Customers exchange their native currency for the currency of the country they are visiting. On the other hand, currency conversions are the process of converting prices to match the customer's native currency.

For example: Suppose you have 40 cents, how many cents would you need to make one dollar!

You can understand this through the following conversion. Since, $1 = 100¢, therefore, we subtract 40 cents from 100 cents. That is 100 cents – 40 cents = 60 cents. Since you already have 40¢, you would need 60¢ more to make it a dollar. This is how we can express 60 cents with different coins.
