Answer: The number of elk that are likely to be infected can be estimated using the sample proportion of infected elk. The sample proportion is the ratio of the number of infected elk in the sample to the total number of elk in the sample.

In this case, the sample proportion is:

7/50 = 0.14

This proportion can be used to estimate the proportion of the entire population of elk that is infected. To do this, we can multiply the sample proportion by the total population of elk and round to the nearest whole number.

0.14 * 6,000 = 840

So, it's likely that 840 elk are infected.

Please note that this is an estimate and the actual number of infected elk could be different. Additionally, this estimation is based on a random sample, so it can have a margin of error.

Answer:

graphing on a graph

Step-by-step explanation:

The cruise ship will be 70 units (could be nautical miles, kilometers or any other unit) away from the iceberg.

What is the slope intercept?

The slope-intercept form of a linear equation is y = mx + b, where x and y are the coordinates of a point on the line, m is the slope of the line (the steepness of the line), and b is the y-intercept (the point where the line crosses the y-axis).

To determine how close the cruise ship will get to the iceberg, we need to find the point of intersection between the ship's path (y = x + 40) and the location of the iceberg (x = 40, y = 10).

Substituting x = 40 into y = x + 40, we get:

y = 40 + 40

y = 80

So the point of intersection is at (40, 80).

We can then use the distance formula to find the distance between the point of intersection and the location of the iceberg:

d = √((40 - 40)^2 + (80 - 10)^2)

d = √((0)^2 + (70)^2)

d = 70

So the cruise ship will be 70 units (could be nautical miles, kilometers or any other unit) away from the iceberg.

The x-coordinates of the endpoints are the same.

What are the coordinates?

Coordinates are a set of numbers that are used to specify the position of a point on a graph or a coordinate plane. The most common type of coordinate system is the Cartesian coordinate system, which uses two perpendicular number lines called the x-axis and the y-axis to define the position of a point.

When talking about coordinates, there are two types of coordinates: x-coordinates and y-coordinates. The x-coordinate refers to the horizontal position of a point on a graph or a coordinate plane, while the y-coordinate refers to the vertical position of the point.

In the statement "The x-coordinates of the endpoints are the same," it means that the horizontal position of the two endpoints is the same. These endpoints could be the two points that define a line segment, a geometric figure, or a graph. The x-coordinates of both of these points are the same, while the y-coordinates could be different.

In a connection that is represented by an exponential function, the independent variable's proportional change is unchanged with a constant change in the independent variable.

Calculating the exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function. Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread.

When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x.

After x hours, you will have twice as much germs if you start with one and it doubles every hour. F(x) = 2x can be used to express this.

The fundamental exponential function generally has the shape,

y = nakx-------

(0,3) is the function's y intercept.

This location has to satisfy the equation (1). So let's substitute in order to get,

3 = na k(0)

⇒ 3 = n x a 0

⇒ 3 = n x 1

⇒ n = 3

Our equation 1 now changes.

y = nakx-------

Noting that the graph crosses through,(1 ,1) it must also satisfy its equation because it does so. Equation (2) can be solved by substituting this point, giving us

To solve this problem we must perform the following algebraic operations with the given information

Calculate the days from 08/21/2019 to 08/21/2022, we get:

Days 1 = (08/21/2022 - 08/21/2019) * (365 days/1 year)

Days 1 = 3 years * (365 days/1 year)

Days 1 = 1095 days

Calculate the days from 05/21/2019 to 08/21/2019, we get:

Days 2 = (08/21/2019 - 05/21/2019) * (30 days / 1 month)

Days 2 = 3 months * (30 days / 1 month)

Days 2 = 90 days

Calculating the days from 05/20/2019 to 05/21/2019, we get:

Days 3 = 05/21/2019 - 05/20/2019

Days 3 = 1 day

The rate of the jet in still air is 741 mph, and the rate of the wind is 150 mph.

What is rate ?

A rate is a ratio of two quantities, typically a change in one quantity over a corresponding change in another quantity, often over a specific time period. For example, the interest rate on a loan is the ratio of the interest paid to the amount of the loan. A speed is a rate at which an object covers distance, velocity is a rate of change of position, etc.

To find the rate of the jet in still air:

Rate = Distance / Time

The distance is 2964 miles, and the time is 4 hours. So the rate of the jet in still air is:

Rate = 2964 / 4 = 741 mph

To find the rate of the wind, you can use the formula:

Wind Rate = (Distance with wind - Distance against wind) / Time

The distance with the wind is 3564 miles, the distance against the wind is 2964 miles, and the time is 4 hours. So the rate of the wind is:

Wind Rate = (3564 - 2964) / 4 = 600 / 4 = 150 mph

So the rate of the jet in still air is 741 mph, and the rate of the wind is 150 mph.

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 2

Using the points, we have

6 = 3m + 2

So, we have

3m = 4

Divide

m = 4/3

So, the equation is

y = 4/3x + 2

For the other parallel line, we have

The slopes of parallel and perpendicular lines are opposite reciprocals

So, we have

Simply draw a dashed line at 6 and shade below the line

Inequalities are relationships between numbers or expressions that show whether a value is greater, less, or equal to another value.

Graph of y = 6

The first step of graphing any inequality is to graph it as though it were an equation. So, first graph the line y = 6. This line is a horizontal line at the y-value 6.

Then, go back to the inequality. The inequality states that y is less than 6. Since there is no "or equal to" sign, the line should be dotted. If there were an "or equal to" sign, then the line should have been solid. This is because the solutions to the inequality do not include 6.

Shading

Whenever you graph an inequality, the portion of the graph that satisfies the inequality should be shaded. In this case, the inequality is looking for all y-values less than 6. So, the portion of the graph under the line should be shaded in.

As per the concept of compounding interest, the amount he deposited on each year is $471.55

Compounding interest in math is the term defined as the interest on a deposit calculated based on both the initial principal and the accumulated interest from previous periods.

Here we know that the final amount is 12,400.00 and the time period is 13 years and interest rate is 6.05%.

Here we have identified that the compounding frequency is monthly basis.

Then the amount is calculated by using the compound interest formula

A = P(1 + r/n)ⁿˣ

Here we have to convert R as a percent to r as a decimal

r = R/100

r = 6.05/100

r = 0.0605 per year,

Now we have to solve the equation for P

P = A / (1 + r/n)ⁿˣ

P = 12,400.00 / (1 + 0.0605/12)⁽¹²ˣ¹³⁾

P = 12,400.00 / (1 + 0.0050416666666667)¹⁵⁶
