Given Dr. Sparrow's design, his study is best able to overcome the issue of causality, as well as the issue of some potential third variables.

By using a multivariate design, Dr. Sparrow is able to examine the relationships between multiple variables simultaneously, which can help to identify the potential influence of each variable on the outcome of interest (marital satisfaction in this case). This can help to establish a causal link between the variables if one is present, as it allows for the examination of multiple variables at the same time, rather than just two variables as in a simple bivariate design.

Additionally, by controlling for other potential confounding variables, Dr. Sparrow is able to account for the potential influence of these variables on the relationship between income and marital satisfaction, which helps to establish a more robust understanding of the potential causal link between these two variables.

The equation of the perpendicular line is (c) y = 2/9x - 1

From the question, we have the following parameters that can be used in our computation:

y + 17 = -9/2(x - 3)

Also, from the question;

We have the following points

Point = (0, -1) i.e.  (x, y) = (0, -1)

The equation of a line can be represented as

y - y₁ = m(x - x₁)

Where

Slope = m

By comparing the equations, we have the following

m = -9/2

This means that the slope is -9/2

The slopes of perpendicular lines are opposite reciprocals

This means that the slope of the other line is 2/9

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = 2/9

(x₁, y₁) = (0, -1)

So, we have

y + 1 = 2/9(x - 0)

Evaluate

y = 2/9x - 1

Hence, the line has an equation of y = 2/9x - 1

Only the first statement is false. The rest are true statements about the Central Limit Theorem.

The Central Limit Theorem (CLT) is a fundamental theorem in probability and statistics which states that, given a sufficiently large sample size from a population with a given mean and standard deviation, the sampling distribution of the mean will be nearly normal, regardless of the shape of the original population distribution.

It is important to note that the first statement presented is false. Taking more samples from the population will not necessarily result in a more normal sampling distribution. The CLT does not guarantee that the sampling distribution will be normally distributed, only that it is more likely to be so as the sample size increases.

The second statement is true. If the population distribution is normal, the sampling distribution of the mean will also be nearly normal, regardless of the sample size. The third statement is also true. As the sample size increases, the sampling distribution of the mean is more likely to be nearly normal, regardless of the shape of the original population distribution.

Finally, the fourth statement is also true. The CLT states that the sampling distribution will be centered at the true population parameter. This means that the mean of the sampling distribution will be equal to the mean of the population.

Let the base and height of triangle be b and h.

area of triangle= 1/2*base*height

Area of triangle= bh/2

Now Base is Doubled and Height increase by 30%

New base = 2b

New height = h×130/100 = 13h/10

New area = 1/2 × 2b × 13h/10

New area = 13bh/10

Area increased = New area - area

Area increased = 13bh/10 - bh/2

Area increased= 13bh-5bh/10

Area increased= 8bh/10

Area increased= 4bh/5

ratio increased in % = Area increased/ Old Area × 100

ratio increased in % = 4bh/5 ÷ bh/2 × 100

ratio increased in % = 4/bh × 2/bh × 20

ratio increased in % = 8×20

ratio increased in % = 160%

According to the information in the graph, the blend of foods that satisfies the requirements at the minimum cost is option A because it would be worth only 10.

To calculate the cheapest blend of food option, we must take into account the amounts of each element (carbohydrate, protein, fat) and identify how many units of each blend we need to cover the minimum quota.

Based on the above information, to identify the blend units we need to cover the minimum quota we must find it by multiplying each of the elements by the number of times we would need to meet the minimum requirement. Once we identify the quantities we need, we must multiply the price by the number of units we need.

Following the previous procedure, we can identify that the best option would be blend A because we must buy it 5 times to cover the minimum requirements. Additionally, its value would be 10, while the others would have a higher value.

The rate at which the area of the forest is increasing, in square kilometers per decade, is 0.0041.

What does the rate of change mean?

How quickly one variable changes in relation to another is known as the rate of change. Speed is an example of a "rate of change." Speed is defined as the rate at which the distance to an object varies in relation to the time spent.

It is given that there are 640 acres in 1 square mile which can also be written as  640 acres= 1[tex]mi^2[/tex].

The area of forest is increasing at a rate of 1 acre/decade.

It is given that 1 km= 0.62mi

By squaring on both sides we will get 1 [tex]km^2[/tex] = 0.3844 [tex]mi^2[/tex].

The rate at which the area of forests is increasing in square kilometers per decade is

Answer:

y = 3x + 2

Step-by-step explanation:

In the equation [tex]y = mx + b[/tex], m represents the slope, and b represents the y-intercept. To write the equation in this form, we must substitute m and b into this equation.

. . . . . . . . . . . Finding "b"

The y-intercept is another name for the y-value when the x- value = 0. So, we need to look at the table and find the y-value for when x = 0.

⭐ y = 2 when x = 0. Thus, b = 2.

. . . . . . . . . . . Substitute "b" into the equation

 y = mx + 2

. . . . . . . . . . . One way to find "m"

 m, your slope, can be found using the slope formula: [tex]m = \frac{y__2 - y__1}{x__2 - x__1}[/tex], where [tex](x__1, y__1)[/tex] and [tex](y__2, y__1)[/tex] are coordinates that you are given.

I am going to choose the coordinates (0,2) and (1,5), but you can choose any other 2 coordinates from the table.

m = (5 - 2)/(1-0)

m = 3/1

⭐ m = 3

. . . . . . . . . . . Another way to find "m"

  m, your slope, can be found by substituting a coordinate that you are given into your equation with b already found.

y = mx + 2

I am going to use the coordinate (1,5), but you can choose another coordinate from the table if you'd like.

-2 + 5 = 1(m) + 2 -2

⭐ 3 = m

. . . . . . . . . . . Substitute "m" into the equation

 y = 3x + 2

Answer:

(0,2)

2 = b

(1,5)

5 = m + b

(2,8)

8 = m(2) + b
