There are 8 possible samples of size 3 that can be drawn in succession with replacement from a population of size 2.

The population size is 2, and we want to draw a sample of size 3 with replacement. With replacement means that after each draw, the item is placed back into the population, so it can be drawn again in the next draw.

To calculate the number of possible samples, we need to consider the number of choices for each draw. Since we are drawing with replacement, we have 2 choices for each draw, which are the items in the population.

To find the total number of possible samples, we need to multiply the number of choices for each draw by itself for the number of draws. In this case, we have 2 choices for each of the 3 draws, so we calculate it as follows:

2 choices x 2 choices x 2 choices = 8 possible samples

Therefore, there are 8 possible samples of size 3 that can be drawn in succession with replacement from a population of size 2.

Let \(P(t) = 240.480 / (1 + 39e^(-0.3t))\) = \(2401 + 39e^(-0.3t)\) = \(248e^(-0.3t)\)= 8.Taking the natural logarithm of both sides, we obtain:\(ln e^(-0.3t) = ln (8)\),\(t = (-1/0.3) ln(8)\).We get:t = 7.9 to one decimal point.

Here we are required to find the time at which the number of infected students will be 240. We are given a function which models the number of students infected with the flu on a college campus after t days. The function is given by

\(P(t) = 480 / (1 + 39e^(-0.3t)).\).

To determine the time at which P(t) = 240, we substitute this value of P(t) into the function. That is:

\(240 = 480 / (1 + 39e^(-0.3t))\)

Multiplying both sides of the equation by \((1 + 39e^(-0.3t))\), we get:

\(240(1 + 39e^(-0.3t)) = 480\)

Distributing the left-hand side, we obtain:

\(240 + 936e^(-0.3t) = 480\)

Subtracting 240 from both sides, we get:

\(936e^(-0.3t) = 240\)

Simplifying this expression by dividing both sides by 936, we obtain:

\(e^(-0.3t) = 0.2564\)

Taking the natural logarithm of both sides, we obtain:

\(ln e^(-0.3t) = ln (0.2564)\)

\(ln e^(-0.3t) = -0.3t\\\\ln (0.2564) = -0.3t\)

Dividing both sides by -0.3, we obtain:

\(t = (-1/0.3) ln (0.2564)\)

Simplifying this expression, we obtain:

t ≈ 8 days

Therefore, the number of infected students will be 240 after approximately 8 days.the number of infected students on a college campus after t days is given by \(P(t) = 480 / (1 + 39e^(-0.3t)).\) To determine the time at which the number of infected students will be 240, we substitute this value into the function and solve for t. We obtain t ≈ 8 days.

Answer:

only the v-shaped graph is a function

Step-by-step explanation:

the circle, the vertical line, and the sideways parabola would not pass the 'vertical line test' which is where, if a vertical line is drawn through the graph then the line would not intersect the graph in more than one point

1. A

Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

--------------------------------------------------------------------------------------------------------------

2. C

That's right. If a system of equations has a solution, then their graphs intersect,  and the point where they intersect is the solution because it's the point that  satisfies each equation in the system.

Straight-line graphs with the same slope are parallel lines, and they never intersect,  which is another way of saying they have no solution.

If the ratio increases the power of x, there is no upper limit. If the ratio reduces the power of x to zero, the limit is zero.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Let's assume that X is the quantity of multiple-choice questions and Y is the quantity of short-answer questions.

Given that the short-answer questions are worth four points and the multiple-choice questions are for two, the equation is 2X + 4Y = 100.

Thus the equation for 2 points each, and short-response questions are worth 4 points each. The assessment is worth 100 total points where x represent the number of multiple-choice questions, and let y represent the number of short-response questions.

If the perimeter is 183 feet then the dimensions are 39ft, 78ft, 66ft

What is a perimeter?

A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter.

The perimeter of a triangle

P = a + b + c.

Here,

We let the length of the shortest side of the triangular flower bed be

x feet.

Then the length of the second side is 2x and

the length of the third side is x+27

The given perimeter is 183ft so,

By applying the perimeter of the triangle formula, we get

x + 2x + x +27 = 187

4x + 27 = 187

4x = 183 - 27

x = 39

the length of the second side is 2*39 = 78ft and

the length of the third side is x+27 = 66ft

Hence, if the perimeter is 183 feet then the dimensions are 39ft, 78ft, and 66ft.

squaring both sides and simplifying, we get,

\(x-y=5\\(x-y)^2=5^2\\(x-y)^2=25\\x^2+y^2-2(xy)=25\\but\ we \ know\ that,\ xy = 15\\so,\\x^2+y^2-2(15)=25\\x^2+y^2-30=25\\x^2+y^2=25+30\\x^2+y^2=55\)

A linear regression equation that represents this set of data is y = 31x + 799.8.

The calendar year in which the number of new cases would reach 1141 is 2022.

In this scenario, the Year since 2011 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.

On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.

By critically observing the scatterplot (see attachment) which models the relationship given in the table for the Year since 2011 (x) and the New cases (y), an equation for the linear regression is given by:

y = 31x + 799.8

Now, we can estimate the calendar year in which the number of new cases would reach 1141:

1141 = 31x + 799.8

31x = 1141 - 799.8

31x = 341.2

x = 341.2/31

x = 11.0

For the first problem, using the monthly payment formula monthly deposit needed is $118.69. For the second problem, using the same formula the monthly payment is $1029.73.

We have the following variables

P = Monthly payment

r = Annual interest rate = 3.7% = 0.037/12 per month

n = Number of payments = 15 months

A = Amount to be saved = $1800

Using the monthly payment formula

P = (r * A) / (1 - (1 + r)⁻ⁿ)

Substituting the given values

P = (0.003083 * 1800) / (1 - (1 + 0.003083)⁻¹⁵)

P ≈ $118.69

Therefore, you should deposit approximately $118.69 each month to save $1800 in 15 months, assuming an APR of 3.7%, compounded monthly.

We have the following variables

P = Monthly payment

r = Annual interest rate = 9.1% = 0.091/12 per month

n = Number of payments = 30 years * 12 months = 360 months

A = Mortgage amount = $127,000

Using the monthly payment formula

P = (r * A) / (1 - (1 + r)⁻ⁿ)

Substituting the given values

P = (0.007583 * 127000) / (1 - (1 + 0.007583)⁻³⁶⁰)

P ≈ $1029.73

Therefore, the monthly payment for a shack mortgage of $127,000 with a fixed APR of 9.1% for 30 years would be approximately $1029.73.
