Students in a high school mathematics class decided that their term project would be a study of the strictness of the parents or guardians of students in the school. Their goal was to estimate the proportion of students in the school who thought of their parents or guardians as “strict”. They do not have time to interview all 1000 students in the school, so they plan to obtain data from a sample of students.
1. Describe the parameter of interest and a statistic the students could use to estimate the parameter.



2. Is the best design for this study a sample survey, an experiment, or an observational study? Explain your reasoning.



3. The students quickly realized that, as there is no definition of “strict”, they could not simply ask a student, “Are your parents or guardians strict?” Write three questions that could provide objective data related to strictness.



4. Describe an appropriate method for obtaining a sample of 100 students, based on your answer in question 1.

Answer: the population density is approximately 121.75 people/km^2.

Step-by-step explanation: Assuming a scenario whereby the island in question is entirely populated and encompasses a total expanse of 100 square kilometers, it follows that the resulting population density would be as follows:

The formula for population density can be expressed as the ratio of total population to a given geographic area. Mathematically, it is written as Population density = Population / Area.

The metric for measuring population density yields a value of 121.75 individuals per hectare.

The metric expressing the number of individuals residing in a given geographic area is referred to as population density. In this specific instance, the population density is calculated to be 121.75 persons per square kilometer.

Therefore, the solution to the system of equations is: x = 13/12, y = -3/4 that is option C.

In mathematics, an equation is a statement that asserts the equality of two expressions, separated by an equals sign (=). The expressions on either side of the equals sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation. Equations are used to describe relationships between variables and to solve problems.

Here,

To solve the system of equations:

4y + 12x = 10 ...(1)

2y - 6x = -8 ...(2)

We can use the method of elimination or substitution.

Method of elimination:

We can eliminate x by multiplying equation (2) by 2 and adding it to equation (1) to obtain:

4y + 12x = 10

(4y - 12x = -16)

8y = -6

Dividing both sides by 8, we get:

y = -6/8

y = -3/4

Substituting this value of y in equation (1), we get:

4(-3/4) + 12x = 10

Simplifying and solving for x, we get:

-3 + 12x = 10

12x = 13

x = 13/12

So the answer is C. x = 13/12, y = -3/4.

Marcus is using a plant food to fertilize his garden his garden is a rectangle Marcus uses 1 cup of plant food for every square yard of his garden.

To solve it, we need to first find the area of Marcus's garden in square yards, and then multiply it by 1 cup of plant food per square yard. Finally, we need to convert the total cups to ounces using the given conversion rate.

Let the length of Marcus's garden is l yards and the width is w yards. Then the area of his garden in square yards is

A = lw.

If Marcus uses 1 cup of plant food per square yard, then he will use A cups of plant food in total.

To convert cups to ounces, we can use the given conversion rate of 4 cups per 28 ounces.

1 cup = 28/4 ounces

Therefore, the total weight of plant food Marcus uses in ounces is

Total weight = A * (28/4) ounces

By substituting A = lw, we get

Total weight = lw * (28/4) ounces

Total weight = 7lw ounces

Hence, the total weight of plant food Marcus uses to fertilize his garden is 7 times the product of the length and width of his garden, measured in yards.

Yes, it is possible for the range of a data set of positive data values to be less than the mean of that data set.

The range of a data set is the difference between the maximum and minimum values in the data set, while the mean (also known as the average) of a data set is the sum of all the values divided by the total number of values.

For example, consider the following data set of positive values: {2, 3, 5, 7, 9}. The range of this data set is 9 - 2 = 7, while the mean is (2 + 3 + 5 + 7 + 9)/5 = 26/5 = 5.2. In this case, the range (7) is less than the mean (5.2).

This can occur when the data set has a relatively small range, meaning that the difference between the maximum and minimum values is not very large compared to the mean.

the distribution of the data set and the specific values within it can affect the relationship between the range and the mean.

It's important to note that range and mean are just two measures of central tendency and variability, and other measures such as median, mode, and standard deviation can provide additional insights into the characteristics of a data set.

only the equation y=1/x shows an indirect proportional relationship, while the other three equations show either a direct proportional or a linear relationship.

How to solve the question?

The mathematical term "indirectly proportional" refers to a relationship in which two variables are related in such a way that when one increases, the other decreases, and vice versa. In other words, the two variables vary in opposite directions.

Out of the four equations given, only one shows an indirect proportional relationship. This equation is:

y=1/x

In this equation, y and x are indirectly proportional. As x increases, the value of 1/x decreases, and therefore, the value of y decreases as well. Similarly, as x decreases, the value of 1/x increases, and the value of y increases as well. This relationship is commonly known as an inverse relationship, where the two variables vary in opposite directions.

On the other hand, the other three equations do not show an indirect proportional relationship. The equation y=5x shows a direct proportional relationship, where y increases as x increases and vice versa. The equation y=-2x+1 is a linear equation with a negative slope, where y decreases as x increases, and y increases as x decreases. Lastly, the equation y=3x+5 is also a linear equation with a positive slope, where y increases as x increases, and y decreases as x decreases.

In summary, only the equation y=1/x shows an indirect proportional relationship, while the other three equations show either a direct proportional or a linear relationship.

In this problem, we are given the angle A, and the side lengths a and b of triangle ABC. Using the   Geometry concept of Law of Sines, we can solve for the remaining angles and side lengths of the triangle. We find that sin(B) ≈ ∠B ≈ ° and ∠C ≈ °, and we can calculate that c ≈ 9.69. This gives us one possible triangle that satisfies the given conditions.

However, the problem states that there are two triangles that satisfy these conditions. To find the second triangle, we must first construct a triangle with angle A₁ = 180° - A and sides a₁ and b₁ such that a₁/b₁ = a/b. This is possible because the Law of Sines tells us that this ratio is constant for all three sides of a triangle. We then apply the Law of Sines to this new triangle to solve for its remaining parts. We find that sin(B₁) ≈ ∠B₁ ≈ ° and ∠C₁ ≈ °, and we can calculate that c₁ ≈ 12.02. This gives us the second possible triangle that satisfies the given conditions.

Now, to show that the areas of the two triangles are proportional to the sines of their respective angles C and C₁, we use the area formula for a triangle, which is 1/2 * base * height. The height of each triangle can be calculated using the sine of the angle opposite the base. Therefore, we have:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (1/2 * a * c * sin(C)) / (1/2 * a₁ * c₁ * sin(C₁))

We can simplify this expression by substituting a1/b1 for a/b and simplifying:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (a/b) * (c/c₁) * (sin(C)/sin(C₁))

Using the Law of Sines, we know that a/b = sin(A)/sin(B) and c/c₁ = sin(C)/sin(C₁), so we can substitute these values into our expression:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (sin(A)/sin(B)) * (sin(C)/sin(C₁)) * (sin(C)/sin(C₁))

Using the fact that the angles in a triangle sum to 180°, we can solve for sin(A) and sin(B):

sin(A) = sin(180° - B - C) = sin(B + C)

sin(B) = sin(180° - A - C) = sin(A + C)

Substituting these values into our expression, we get:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (sin(B + C)/sin(B)) * (sin(C)/sin(C₁)) * (sin(C)/sin(C₁))

Simplifying this expression, we get:

Area of ΔABC/ Area of ΔA₁B₁C₁ = sin(C)/sin(C₁)

Therefore, the areas of the two triangles are proportional to the sines of their respective angles C and C₁

The probability of rolling an even number on a dice is 1/2, since there are three even numbers (2, 4, and 6) out of a total of six possible outcomes (1, 2, 3, 4, 5, and 6).

The probability of landing on tails when flipping a coin is also 1/2, since there are only two possible outcomes (heads or tails) and they are equally likely.

To find the probability of both events happening together, we need to multiply their probabilities:

1/2 (probability of rolling an even number) x 1/2 (probability of landing on tails) = 1/4

Therefore, the probability of rolling an even number on a dice and landing on tails when flipping a coin is 1/4 or 0.25 (25%).
