Step-by-step explanation:

a) The highway affected the growth of many plant species, which serve as food for the deer. Option D

b) There will be fewer population of the birds. Option C

The carrying capacity of an ecosystem is the maximum number of individuals of a particular species that can be supported by the available resources in that ecosystem.

It is the point at which the population growth rate becomes zero, as the resources needed to sustain the population (such as food, water, and space) become limited. Carrying capacity can change over time due to factors such as climate change, pollution, and human activity.

Step-by-step explanation:

the sum of the area of the inner rectangle and the area of the 2 outer half-circles (that together are the area of one full circle).

the radius of the circles is 10 ft.

so, the diameter (= the width of the inner rectangle) = 2×10 = 20 ft.

so, the area of the inner rectangle is

30×20 = 600 ft²

the area of the combined full circle is

pi×r² = pi×10² = 100pi = 314.1592654... ft²

together that is

914.1592654... ft²

The function best represents the data in the scatter plot is y = 2x + 20.

The function of the straight line has the general formula: y = mx + c

where m is the slope of the line, and c is the y-intercept

So first, we will need to find the slope (m):

The slope can be calculated with the points (x₁, y₁) and (x₂, y₂) as follows:

m = (y₂ - y₁)/(x₂ - x₁)

= 120 - 60/50 - 20

= 60/30

= 2/1

So, now we have the slope of our equation y = 2x + b but we still need to find b (or where the y intersects.)

Now, consider the ordered pair (20, 60)

y = 2x + b

60 = 2 × 20 + b

b = 60 - 40

b = 20

Now, put the value of b in y = 2x + b, and we get

y = 2x + 20

Also, b can not be -20 because this is a positive y-intercept, and we know it has a slope of 2.

Therefore the function is y = 2x + 20

a. (-1,5)

The distance from the point (-1,5) to the focus (-1,6) is sqrt((-1-(-1))^2 + (5-6)^2) = sqrt(0+1) = 1

The distance from the point (-1,5) to the directrix y=4 is the absolute value of the y-coordinate of the point - the y-coordinate of the directrix = abs(5-4) = 1

Here we see two sides being congruent and one angle, this means that the other angles are also congruent, as only one triangle can be formed with two set sides and an angle. therefore we know both triangles are congruent

The G.C.F. of the expression 16n - 24 is evaluated to be 8(2n - 3).

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is - 16n - 24.

The greatest common factor, which is the product of two or more numbers, is the largest number (GCF). A natural number is created by dividing them by the biggest number (factor).

First of all find the G.C.F of 16n and 24 separately.

It can be written that -

16n = 2 × 2 × 2 × 2 × n

24 = 2 × 2 × 2 × 3

The common prime factor between the two is 2 × 2 × 2 = 8.

So, the GCF of 16n and 24 is 8.

Now use the GCF to factor the expression -

= 16n - 24

= 8(2n) - 8(3)

Using the distributive property -

= 8(2n) - 8(3)

= 8(2n - 3)

Therefore, the GCF value is 8(2n - 3).

In this question we find the case of a system of two linear equations with two variables, this case may have an unique solution. This system can be solved by algebraic properties.

First, write the system of linear equations:

4 · y - 12 · x = 3

y + 3 · x = 1

Second, clear y in the second equation:

y = 1 - 3 · x

Third, substitute in the first equation:

4 · (1 - 3 · x) - 12 · x = 3

Fourth, expand the expression and clear variable x:

4 - 12 · x - 12 · x = 3

4 - 24 · x = 3

24 · x = 4 - 3

24 · x = 1

x = 1 / 24

Fifth, determine the value of variable y:

y = 1 - 3 · (1 / 24)

y = 1 - 1 / 8

The different combinations of the five-digit number formed are enough to create ID numbers.

What is meant by combinations?

Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant.

We first find the total number of 5-digit enrollment IDs that can be created using all possible combinations of numbers possible.

Since each digit of the five-digit number can be from 0-9, there are ten possible values for each digit.

So the total number of ways a five-digit number can be formed

= 10*10*10*10*10 = 100,000

For the given question, it is mentioned that only 75,000 students are expected to be enrolled in the next ten years,

Since 100,000 is greater than 75,000 the five-digit ID number will be enough.

But if the school is to last longer than ten years, it is safe to use a six or seven-digit ID number.

Therefore a five-digit Id number using symbols from 0-9 will be enough.

Another presentation that is similar to a histogram is a stemplot. In statistics, a stemplot is a tool for presenting quantitative data in a graphical format, similar to a histogram, namely to assist in visualizing the shape of the data distribution which is often used in exploratory analysis. Stemplots were introduced by Arthur Bowley in the early 1900's. However, its general use only began in 1980 after John Tukey's published Exploratory Data Analysis in 1977.

Stem-and-leaf plots provide more information about true values than histograms. As in a histogram, the length of each bar corresponds to the number of events that fall into a given interval. On Histograms. we can only see the frequency value of the data but we don't know what the actual number value is. In contrast to the histogram, in SLP besides we can know the frequency value, we can also know what the actual data value is. This is done by dividing the observed values into two components, stem and leaf.

If a plot of the residuals shows a curved pattern, it indicates that a straight line is not a good model for the data. This does not necessarily mean that the correlation between the two variables must be 0 or positive, as the regression line might still be a good model for the data depending on the extent of the curve.

When a least-squares regression line is fit to a set of data, it is used to determine the linear relationship between two variables. If a plot of the residuals (the difference between the observed values and the predicted values from the regression line) shows a curved pattern, it indicates that a straight line is not a good model for the data. This could mean that there is a nonlinear relationship between the two variables or that the data contains outliers that are not accounted for by the regression line. However, it does not necessarily mean that the correlation between the two variables must be 0 or positive, as the regression line might still be a good model for the data depending on the extent of the curve. To determine if the regression line is an accurate model for the data, it is important to visually inspect the plot of the residuals and assess whether the pattern is random or systematic. If the pattern is random, it indicates that the regression line is a good model for the data. If the pattern is systematic, it indicates that the regression line is not a good model for the data and alternative models should be considered.
