Answer:

To compare who saves the most of their salary each month among Amy, John, and Emily, we need to calculate the amount of salary each person saves.

Let's assume that the monthly salary of each person is 'S'. Then we can calculate the amount saved by each person as follows:

Amy:

Amount saved = 20% of S = 0.2S

Amount spent = S - 0.2S = 0.8S

John:

Amount spent = 2/5 of S = (2/5)S

Amount saved = S - (2/5)S = (3/5)S

Emily:

Let's assume that Emily saves '5x' and spends '8x' of her monthly salary.

Then, according to the question, we have:

Amount saved = 5x

Amount spent = 8x

We know that the ratio of the amount saved to the amount spent is 5:8, so we can write:

Amount saved / Amount spent = 5/8

Substituting the values of amount saved and amount spent, we get:

5x / 8x = 5/8

5x = (5/8) x 8x

5x = 5x

Therefore, the ratio of amount saved to amount spent is equal to 5:8. This means that Emily saves 5/13 of her monthly salary and spends 8/13 of her monthly salary.

So, the amount saved by each person is:

Amy: 0.2S

John: (3/5)S

Emily: 5/13 of S

Now, we need to compare these amounts to find out who saves the most.

To compare these amounts, we can write them in terms of a common denominator:

Amy: 0.2S

John: (3/5)S = (0.6)S

Emily: (5/13)S = (0.3846)S (approx.)

Therefore, we see that John saves the most of his salary each month, followed by Amy and then Emily.

Working out:

Let's assume that each person earns $1000 per month.

Amy:

Amount saved = 20% of $1000 = $200

Amount spent = $800

John:

Amount spent = 2/5 of $1000 = $400

Amount saved = $1000 - $400 = $600

Emily:

Let's assume that Emily saves $5x and spends $8x of her monthly salary.

Then, we have:

Amount saved = $5x

Amount spent = $8x

We know that the ratio of the amount saved to the amount spent is 5:8, so we can write:

$5x / $8x = 5/8

Solving for x, we get:

x = 8/13

Substituting the value of x, we get:

Amount saved = $5 x (8/13) x $1000 = $384.62 (approx.)

Amount spent = $8 x (8/13) x $1000 = $615.38 (approx.)

Therefore, we see that John saves the most of his salary each month, followed by Amy and then Emily.

Answer:

B

Step-by-step explanation:

that is the definition of a function : every valid value of x gets exactly one value of y assigned as function result value.

that allows gaps. not every value on the x-axis has to be a valid x value for the function. and neither do we need every possible y value to be a valid function result value.

so, if we consider x to be the set of {2, 4, 6, 9}, then this is indeed a function.

2 gets 3, 4 gets 9, 6 gets 10, and 9 gets 5 assigned as y (function result) value.

all good and perfect - exactly one assigned value for every valid x value.

Example of Divergent Plate: Mid Atlantic ridge, Red Sea Ridge, and Southeast Indian Ridge.

Example of Convergent Plate: The collision between the Eurasian Plate and the Indian Plate.

Example of Transform Plate: San Andreas Fault Zone of western North America.

In plate tectonics, a divergent boundary or divergent plate boundary (also called constructive or extensional boundary) is a linear feature that exists between two tectonic plates moving apart. Diverging boundaries within continents first create rifts that eventually become rift valleys. The most active diverging plate boundaries occur between oceanic plates and exist as mid-ocean ridges.

Recent research suggests that complex convective currents within the Earth's mantle allow matter to rise to the bottom of the lithosphere beneath each divergent plate boundary. This provides the region with a tremendous amount of heat and pressure reduction that melts rock from the asthenosphere (or upper mantle) below the rift region, forming large flood basalts or lava flows.

When continental and oceanic plates collide, the thin, dense oceanic plate is overwritten by the thicker, less dense continental plate. The oceanic plate is being pushed into the mantle in a process known as "subduction." As the oceanic plate sinks, it is forced into a hotter environment. At a depth of about 160 km (100 miles), the material within the subducting plate begins to approach melting temperatures and the process of partial melting begins.

This partial melting creates a magma chamber above the subducting oceanic plate. These magma chambers are less dense and buoyant than the surrounding mantle material. A buoyant magma chamber begins to rise slowly through the material above it, melting and rupturing as it rises. The size and depth of these magma chambers can be determined by mapping the seismic activity around the magma chambers. When a magma chamber rises to the surface without solidifying, magma breaks through in the form of a volcanic eruption.

A third type of plate boundary is a deformation fault where plates slip past each other without creating or breaking the crust. Rocks facing each other on both sides of a fault are usually of different types and ages, because rocks are cut and displaced by movement in opposite directions. These structures are so-called strike faults.

As friction increases and the sliding motion of the blade stops at one point, stress builds up and can be released with abrupt slippage. These can lead to some of the most damaging earthquakes in the continental crust. The San Andreas Fault (western United States), the North Anatolia Fault (Turkey), and the Dolores-Guayaquil Mega Fault in the northern Andes are examples of massive strike faults that cut through the continental crust.

Mid-ocean ridges are also often offset by so-called transformation faults. However, due to its association with stress distribution centers and the varied nature of the oceanic crust, earthquakes occurring there are usually shallow and therefore weak.

The chi-square test of independence is typically used to analyze the relationship between two variables when both variables are nominal, the two variables have been measured on different individuals and the observations on each variable are within-subjects in nature. The answer is  D. all of the above

The chi-square test of independence is a statistical test that is used to determine if there is a significant association between two categorical variables. It is commonly used when both variables are nominal, meaning they consist of categories or groups rather than numerical values.

When conducting the chi-square test of independence, the data is typically collected by measuring the two variables on different individuals or units.

For example, researchers may collect data on the gender (nominal variable) and political affiliation (nominal variable) of different individuals and analyze whether there is a relationship between the two variables.

The test examines the observed frequencies of the different categories in a contingency table and compares them to the expected frequencies under the assumption of independence. If the observed and expected frequencies significantly differ, it suggests that there is an association between the two variables.

Therefore, the chi-square test of independence is applicable when both variables are nominal and the data is collected on different individuals. This allows researchers to investigate the relationship between the variables and determine if they are associated or independent.

The confidence interval of 95% for the data with the provided conditions is [.483, .589].

In the 2009 regular season, catcher Joe Mauer of the Minnesota Twins had 276 hits in 514 at-bats.

The formula for confidence interval is given by:

CI = X ± Z × (σ / √n)

Where, CI = Confidence interval

X = Mean

σ = Standard deviation

Z = Confidence level

n = Sample size

Here, we need to calculate the 95% confidence interval.

So, the value of Z will be 1.96.

Now, we can calculate the mean and standard deviation.

Mean, X = 276 / 514

              = 0.53613

Standard deviation, σ = √[p(1-p)/n]

                                    = √[(276/514) (238/514)]

                                    ≈ 0.0266

So, the confidence interval will be:

CI = 0.53613 ± 1.96 (0.0266 / √514)

    = [0.483, 0.589]

Therefore, the correct option is:  [. 483, . 589].

a) This state-diagram corresponds to a birth-death process because the transitions only depend on the current state and not on any previous history of the system. b) We can sum over all values of mp(n) = ∑p(n,m). c. This system can be modeled as a birth-death process, where the states represent the number of taxis and the number of people waiting in line.

Steady-state probabilities of waiting passengers and taxis can be found using balance equations and summing probabilities for the respective cases

a. To draw the state-diagram for this system, we need to identify the different states of the system. In this case, the states are the number of taxis and the number of people waiting in line. Let's denote the number of taxis by n and the number of people waiting in line by m. The states can be represented as (n,m).

For each state, there are two possible transitions: a taxi can arrive, or a passenger can board a taxi. If a taxi arrives, the system moves to state (n+1,m) with probability μ, if there is room for the taxi. If there is no room, the taxi departs immediately and the system moves to state (n,m) with probability λ. If a passenger boards a taxi, the system moves to state (n,m-1) with probability μ. If there are no passengers waiting, the taxi joins the queue and the system moves to state (n+1,m) with probability λ.

This state-diagram corresponds to a birth-death process because the transitions only depend on the current state and not on any previous history of the system.

b. To find the steady-state probability of having n persons waiting in line, we need to use the balance equations. Let p(n,m) be the steady-state probability of being in state (n,m). Then, the balance equations are:

λp(n-1,m) + μp(n,m-1) = (λ+p)m(n,m) + μ(n+1)p(n+1,m)

for n >= 0 and m >= 0. We also have the normalization condition:

∑p(n,m) = 1.

We can solve these equations to find the steady-state probabilities. In this case, we are interested in the probabilities of having n persons waiting in line, so we can sum over all values of m:

p(n) = ∑p(n,m).

c. To find the steady-state probability of having m taxis waiting in the taxi stand, we can use a similar approach. The balance equations are:

λp(n-1,m) + μp(n,m-1) = λ(n+1)p(n+1,m) + (μ+p)m(n,m)

for n >= 0 and m >= 0. We can solve these equations to find the steady-state probabilities. In this case, we are interested in the probabilities of having m taxis waiting in the stand, so we can sum over all values of n:

p(m) = ∑p(n,m).

Overall, this system can be modeled as a birth-death process, where the states represent the number of taxis and the number of people waiting in line. We can use the balance equations to find the steady-state probabilities of having n persons waiting in line or m taxis waiting in the stand.
