(L5) A(n) _____ is a statement that compares two expressions that are not equal.

The average rainfall over 2 days as per given average rainfall is 6 inches in 30 days is equal to  0.4 inches

Average rainfall is 6 inches in 30 days,

find the average rainfall per day by dividing by 30.

average rainfall per day = 6 inches / 30 days

⇒average rainfall per day = 0.2 inches per day

To find the average rainfall over 2 days = multiply the average rainfall per day by the number of days.

⇒ average rainfall over 2 days = 0.2 inches per day x 2 days

⇒ average rainfall over 2 days = 0.4 inches

This is much less than the 14 inches of rain that Hurricane Katrina dropped in one 48-hour period.

Therefore, the average rainfall over 2 days is 0.4 inches.

If 6 ounces of fish has 36 grams of protein, then the fish has 6 grams of protein per ounce.

To find the weight of protein per-ounce, we divide total number of grams of protein by the total number of ounces of fish.

We know that 6 ounces of fish has 36 grams of protein, so to find the number of grams of protein per ounce, we divide the total number of grams of protein by the total number of ounces;

⇒ grams of protein per ounce = (total grams of protein)/(total ounces of fish),

The total number of grams of protein is = 36, and the total number of ounces of fish is 6,

So, grams of protein per-ounce = 36/6 = 6,

c. All states are positive recurrent, the Markov chain is recurrent.

d. The Markov chain has one absorbing state, it is transient.

a. The Markov chain with transition matrix P1 has 3 states: state 1, state 2, and state 3. To determine if they are transient or recurrent, we need to check if any state is reachable from every other state. It can be shown that all states communicate with each other, so the Markov chain is irreducible. Moreover, since all states are positive recurrent, the Markov chain is recurrent.

b. The Markov chain with transition matrix P2 has 5 states: state 1, state 2, state 3, state 4, and state 5. To determine if they are transient or recurrent, we need to check if any state is reachable from every other state. However, it is clear that state 4 and state 5 are absorbing states and can only transition to themselves. Therefore, these states are not reachable from any other state, and the Markov chain is not irreducible. Moreover, since the Markov chain has two absorbing states, it is transient.

To yield a linear graph, the variables that should be plotted on the horizontal and vertical axes depend on the nature of the process being repeated by the student. If the process involves measuring the dependent variable y for different values of an independent variable x, then x should be plotted on the horizontal (x-axis) and y on the vertical (y-axis). This is because the independent variable is usually plotted on the x-axis, while the dependent variable is plotted on the y-axis. The resulting graph will show how y varies with respect to x, and if the relationship between x and y is linear, the graph will be a straight line.

On the other hand, if the process involves measuring the dependent variable y for different values of another independent variable z, then z should be plotted on the horizontal (x-axis) and y on the vertical (y-axis). This is because in this case, the variable being plotted on the x-axis is still the independent variable, while the dependent variable is still plotted on the y-axis.

In summary, the choice of variables to plot on the horizontal and vertical axes to yield a linear graph depends on the nature of the process being repeated by the student, and whether the process involves measuring the dependent variable y for different values of an independent variable x or another independent variable z.

It should be noted that 5, 7, 9 forms an obtuse triangle.

Also, 5, 10, 5√3 forms an acute triangle.

a² + b² = c²

5² + 7² = 25 + 49 = 74

9² = 81

Since 74 < 81, we know that 5, 7, 9 forms an obtuse triangle.

Again, we apply the Pythagorean theorem.

5² + (5√3)² = 25 + 75 = 100

(2√13)² = 52

Since 100 > 52, we know that 5, 10, 5√3 forms an acute triangle.

Applying the Pythagorean theorem:

(√13)² + 10² = 13 + 100 = 113

12² = 144

Since 113 < 144, we know that √13, 10, 12 forms an obtuse triangle.

Applying the Pythagorean theorem:

16² + 30² = 256 + 900 = 1156

The proportion of students who score between 400 and 600 on the SAT-M is approximately 68.27%.

To find the proportion of students who score between 400 and 600 on the SAT-M, we need to use the standard normal distribution.

First, we need to calculate the z-scores for the lower and upper limits of the range. To do this, we use the formula:

z = (x - μ) / σ

where x is the value we're interested in (400 or 600), μ is the mean score for the SAT-M (which we'll assume is 500), and σ is the standard deviation (which we'll assume is 100).

For 400:
z = (400 - 500) / 100
z = -1

For 600:
z = (600 - 500) / 100
z = 1

Next, we use a standard normal distribution table or calculator to find the area under the curve between these two z-scores.

Using a table or calculator, we find that the area to the left of z = -1 is 0.1587 and the area to the left of z = 1 is 0.8413. To find the area between these two z-scores, we subtract the smaller area from the larger area:

0.8413 - 0.1587 = 0.6826

So the proportion of students who score between 400 and 600 on the SAT-M is approximately 0.6826, or 68.26%.
Hi! To find the proportion of students who score between 400 and 600 on the SAT-M (math section), you need to look at the distribution of scores. The SAT-M scores typically follow a normal distribution with a mean (µ) of 500 and a standard deviation (σ) of 100.

To find the proportion of students who score between 400 and 600, we can use the Z-score formula to standardize the scores:

Z = (X - µ) / σ

For 400: Z1 = (400 - 500) / 100 = -1
For 600: Z2 = (600 - 500) / 100 = 1

Now, we need to find the probability between these two Z-scores, which can be represented as P(-1 < Z < 1). You can find this probability using a standard normal distribution table or a calculator with a normal distribution function. The result is approximately 0.6827, or 68.27%.

So, the proportion of students who score between 400 and 600 on the SAT-M is approximately 68.27%.

If rectangular pyramid has length as 20 in., width as 10 in., and height as  25 in., then the lateral surface area of pyramid is (b) 1000 in².

The "Lateral-Surface-Area" of a rectangular pyramid is the sum of the areas of the four triangular faces that connect the base to the top of pyramid.

Each of these triangular-faces has a base that is equal to the length or width of the rectangular base, and a height that is equal to the overall height of the pyramid.

The base length is = 20 in., the base width is = 10 in., and the overall height is 25 in.

The height of each triangular face is equal to the overall height of the pyramid, which is = 25 in,

To find the lateral surface area, we find the area of one triangular face and multiply it by 4.

So, Area of one triangular face = (1/2) × base × height,

⇒ Area = (1/2) × 20 × 25,

⇒ Area = 250 in²,

So, the area of one triangular face is 250 in².

Since there are 4 triangular faces, the lateral surface area of the pyramid is:

⇒ Lateral surface area = 4 × Area of one triangular face,

⇒ 4 × 250 in²,

⇒ 1000 in²,

Therefore, the correct option is (b).

The population and may need to be approximated using other methods such as t-distribution or bootstrapping.

Population is a group of individuals of the same species living in the same area at the same time. It is a term used in biology, sociology and other fields of study.

Without knowing the specific characteristics of the population, it is difficult to determine the exact distribution of the sample mean of a simple random sample of size 15 drawn from that population.

However, if the population is approximately normally distributed or if the sample size is large enough (usually considered to be n > 30), the sample mean will follow a normal distribution. This is known as the Central Limit Theorem.
Hence, If the population is not normally distributed and the sample size is small, the distribution of the sample mean will depend on the specific characteristics of the population and may need to be approximated using other methods such as the t-distribution or bootstrapping.

The two-way table allows us to calculate the joint distribution, marginal distributions, and conditional distributions for incidents of sexual harassment in middle and high schools. The most appropriate conditional distribution depends on the research question and the factors being considered.

In this study on sexual harassment in middle and high schools, the joint distribution of students who have witnessed sexual harassment in school is given in the two-way table in figure 9.9. We can use this table to calculate the marginal distributions for the number of times sexual harassment was witnessed, as well as the conditional distributions based on other factors, such as gender or grade level.

The two marginal distributions are the number of students who witnessed sexual harassment across all grades and genders. This allows us to see the total number of incidents of sexual harassment and how they vary by grade level or gender.

The conditional distributions are based on additional factors, such as gender or grade level. For example, we can calculate the percentage of female students who witnessed sexual harassment compared to the percentage of male students who witnessed it. We can also calculate the percentage of incidents that occurred in each grade level.

The preferred conditional distribution to explain the results of the analysis depends on the research question. If the research question is focused on gender differences, then the gender-based conditional distribution would be most useful. If the question is focused on grade level differences, then the grade-level based distribution would be more appropriate.

The correct statement regarding whether the graph represents a function is given as follows:

C. Yes, because it passes the vertical line test.

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.

For the graph in this problem, no matter which value of x we plot a vertical line, it would cross the graph of the function only once, hence it passes the vertical line test and it is a function.

The integral on the right-hand side of the given equation depends only on the area of the region R enclosed by C and not on the shape of C or its location in the plane.

We can use Green's theorem to show that the line integral ∫C zd(x) - 2x(d(y)) + 3y(d(z)) depends only on the area of the region enclosed by C and not on the shape of C or its location in the plane.

Green's theorem states that for a simple closed curve C in the xy-plane that encloses a region R, and for a vector field F = P(x, y)i + Q(x, y)j, we have

∫C P(x, y)d(x) + Q(x, y)d(y) = ∫∫R (∂Q/∂x - ∂P/∂y)dA

where dA = dxdy is the area element in the xy-plane.

In our case, the curve C lies in the plane x + y + z = 1. We can rewrite this equation as z = 1 - x - y, so we have a parametric representation of C

r(t) = (x(t), y(t), z(t)) = (t, 1 - t - u, u)

where t and u are parameters that vary along C.

Now, we can calculate the curl of the vector field F = z(x)i - 2x(j) + 3y(k)

∂P/∂y - ∂Q/∂x = -2 - 0 - 1 = -3

Since the curl is a constant (-3) and does not depend on the variables x, y, or z, we can apply Green's theorem to find the line integral of F along C

∫C zd(x) - 2x(d(y)) + 3y(d(z)) = ∫∫R (-3)dA

Therefore, we have shown that the line integral ∫C zd(x) - 2x(d(y)) + 3y(d(z)) depends only on the area of the region enclosed by C and not on the shape of C or its location in the plane.

The scale will read the weight of the water displaced by the cube.

To calculate the weight of the water displaced, we can use Archimedes' principle which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. The weight of the water displaced by the cube can be calculated using the formula:

W = density of water x volume of water displaced x acceleration due to gravity

The volume of water displaced is equal to the volume of the cube, which is 0.3 x 0.3 x 0.3 = 0.027 cubic meters.

The density of water is 1000 kg/m³.

The acceleration due to gravity is 9.8 m/s².

Therefore, the weight of the water displaced is:

W = 1000 x 0.027 x 9.8 = 264.6 N

The p-value for a standardized test statistic of z = -1.86 with the alternative hypothesis Ha: p < 0.5 is 0.0322.

To find the p-value for the standardized test statistic of z = -1.86 with the alternative hypothesis Ha: p < 0.5, we need to find the area under the standard normal distribution curve to the left of z = -1.86.

We can use a standard normal distribution table or a calculator to find this area. Using a calculator, we can use the following steps:

1) Calculate the cumulative distribution function (CDF) of the standard normal distribution at z = -1.86. This gives us the area under the curve to the left of z = -1.86.

CDF(-1.86) = 0.0322

2) Since the alternative hypothesis is one-tailed (p < 0.5), we need to find the area in the left tail of the standard normal distribution. Therefore, the p-value is the same as the area under the curve to the left of z = -1.86.

p-value = 0.0322

So the p-value for a standardized test statistic of z = -1.86 with the alternative hypothesis Ha: p < 0.5 is 0.0322.

b. The correct choice is: "We are 90% confident that the observed proportion of adults that responded 'wrong track' is within 0.017 of the population proportion."

a) To calculate the margin of error for a 90% confidence interval, we need to use the formula:

[tex]ME = z\sqrt{ (pq/n) }[/tex]

where:

z = the z-score for a 90% confidence interval, which is 1.645

p = the proportion of adults who said things were going in the wrong direction, which is 0.44

q = the complement of p, which is 1 - 0.44 = 0.56

n = the sample size, which is 2306.

Plugging in these values, we get:

ME = 1.645sqrt(0.440.56/2306) = 0.017

Therefore, the margin of error for the proportion of all adults who think things are going in the wrong direction for 90% confidence is 0.017.

b) The correct choice is: "We are 90% confident that the observed proportion of adults that responded 'wrong track' is within 0.017 of the population proportion."

This means that if we were to conduct the same survey many times and calculate the confidence interval each time, we would expect 90% of those intervals to contain the true proportion of adults who think things are going in the wrong direction.

The function C(x) = 24x - 12 gives us the number of muffins Chelsea can use for the bake sale in each batch she bakes, based on the number of muffins x she bakes.

The number 24 is the slope or rate of increase of the function, while -12 is the y-intercept or initial value of the function.

Chelsea is making muffins for the school bake sale, but her oven burns hotter on one side than the other. As a result, she ends up with burnt cupcakes in each batch she bakes that cannot be used for the sale. To determine how many muffins she can use for the bake sale in each batch, we have been given a function C(x) = 24x - 12.

Now, let's break down the given function C(x) = 24x - 12. The number 24 is the coefficient of x in the function, and it represents the rate of increase of the function. In other words, for each additional muffin Chelsea bakes in a batch, she can use 24 more muffins for the sale. Therefore, the number 24 is also called the slope of the function.

On the other hand, the value -12 is called the y-intercept of the function, which is the point where the graph of the function intersects the y-axis. It represents the initial number of muffins that Chelsea can use for the sale even if she doesn't bake any muffins. In this case, it means that Chelsea can use 12 muffins for the sale without baking any muffins.
