an athletic facility has 5 tennis courts. pairs of players arrive at the courts and use a court for an exponentially distributed time with mean 40 minutes. suppose a pair of players arrives and finds all courts busy and k other pairs waiting in queue. what is the expected waiting time to get a court?
The expected waiting time to get a court is 8(k + 1).
What is expected time?
The projected time is simply the time frame in which the Project is anticipated to be finished. When the parties to the project contract are signing it, they will either mutually agree upon this time or decide it together with the participation of all the stakeholders, contractors, and clients.
They need to wait for k+1 pairs to finish before they can start.
Since the exponential distribution is memoryless, the expected time for a given pair to finish once started is 40 minutes, and there are 5 courts,
the expected time for any of the 5 courts to finish is 40/5=8 minutes, and so their expected waiting time is 8(k+1) minutes.
Hence, the expected waiting time to get a court is 8(k + 1).

Feline Flavor is cheaper per pound than Kitty Kibbles (or Kitty Kibbles is more expensive than Feline Flavor per pound).
What is unit rate?
A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.
To find the unit price you divide the total cost of the bag by the amount of pounds in the bag.
Thus, the unit price of Kitty Kibbles is 24/16, or 1.5. This means that each pound of Kitty Kibbles costs $1.50.
Also, the unit price of Feline Flavor is 11.20/8, or 1.4. This means that each pound of Feline Flavor costs $1.40

We can determine that we need 216 mL of 100% alcohol and 384 mL of 50% alcohol using the percentage by volume of the solutions that have been provided.
What is the percentage by volume?Volume/volume percentage, often known as v/v percent or %v/v, is a unit used to express how much of a substance is present in a solution.
It is defined as the volume of the solute divided by the sum of the volumes of the solution, multiplied by one hundred.
So, we know that:
A + B = 600 mL
We also understand that the final solution's total alcohol content must equal:
0.68 * 600 mL = 408 mL
So, it follows that:
0.50 * A + B = 408 mL
We can infer the following from the first equation:
A = 600 mL - B
In the second equation, using that A, we obtain:
0.50 * (600 mL - B) + B = 408 mL
300 mL - 0.50 B + B = 408 mL
The result of rearranging this equation is:
B - 0.50 * B = 408 mL - 300 mL
0.50 * B = 108 mL
B = 108 mL / 0.50
B = 216 mL
A = 600 mL - 216 mL = 384 mL
Therefore, we can determine that we need 216 mL of 100% alcohol and 384 mL of 50% alcohol using the percentage by volume of the solutions that have been provided.

Which factors plays a role in establishing the value of a country's currency?
Supply and demand are two factors that affect how much a country's currency is worth.
The supply and demand of a country's currency determine the value of that currency in a free-floating currency exchange market. A currency improves in value or appreciates when demand for it rises. A currency loses value or depreciates when there is less demand for it.
Money's demand determines how much it is worth. When there is still a strong demand for treasuries, the US dollar increases. The value of a currency determines both its supply and demand. For instance, if a nation prints a lot of currency, the value relative to other currencies will drop because supply exceeds demand. Inflation will happen if the cost of products rises or the value of money declines in comparison to other assets.

name examples of a divergent, a convergent, and a transform plate boundary. how are these boundaries different (6 points)?
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.
Divergent Plate: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.
Continental Plate: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.
Transformation Plate: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.

21. a) The average height of sunflowers in a field is 64 in. with a standard deviation of 3.5 in. On a
piece of paper, draw a normal curve for the distribution, including the values on the horizontal
axis at one, two, and three standard deviations from the mean. Describe your drawing in as
much detail as possible, and explain how you came up with each of your labels.
b) If there are 3,000 plants in the field, approximately how many will be taller than 71 in.?
Explain how you got your answer.
To draw a normal curve for the distribution of sunflower heights, first draw a horizontal line across the center of your paper to represent the mean height of 64 inches. Then, draw a bell-shaped curve above and below the line to represent the distribution of heights. The curve should be symmetrical around the mean.
To label the horizontal axis, start by marking the mean at 64 inches. Then, use the standard deviation of 3.5 inches to mark the points that are one, two, and three standard deviations from the mean. This means that the first point will be at 64 - 3.5 = 60.5 inches, the second point will be at 64 - 3.52 = 57 inches, and the third point will be at 64 - 3.53 = 53.5 inches.
To determine the number of sunflowers that will be taller than 71 inches, we can use the normal distribution to calculate the probability that a sunflower will be taller than 71 inches. Because the distribution is symmetrical around the mean, this probability will be the same as the probability that a sunflower will be shorter than 71 inches. We can then multiply this probability by the total number of sunflowers in the field to get the approximate number of sunflowers that will be taller than 71 inches.
To calculate the probability that a sunflower will be shorter than 71 inches, we need to know the z-score corresponding to 71 inches. The z-score is the number of standard deviations that a given value is from the mean. To calculate the z-score, we can use the formula z = (x - mean)/standard deviation, where x is the value we are interested in (71 inches), mean is the mean of the distribution (64 inches), and standard deviation is the standard deviation of the distribution (3.5 inches). Plugging these values into the formula, we get z = (71 - 64)/3.5 = 2.
We can use this z-score to look up the probability of a value being shorter than 71 inches in a standard normal table. A standard normal table is a table that shows the probabilities for different values of the standard normal distribution, which is a normal distribution with a mean of 0 and a standard deviation of 1. Because our distribution has a different mean and standard deviation, we need to convert our z-score to a standard normal value using the formula z_std = (z - mean)/standard deviation. Plugging in the values from our distribution, we get z_std = (2 - 64)/3.5 = -18.3. Looking up this value in a standard normal table, we find that the probability of a value being shorter than -18.3 is 0.00003.
We can use this probability to approximate the number of sunflowers that will be taller than 71 inches by multiplying the probability by the total number of sunflowers in the field. In this case, we have approximately 0.00003 * 3000 = 0.9 sunflowers that will be taller than 71 inches. This is a very small number, so it is likely that there will be no sunflowers in the field that are taller than 71 inches.
How can you determine the shape of a graph?
Answer:
The shape of a distribution is described by its number of peaks and by its possession of symmetry, its tendency to skew, or its uniformity.
if a certain positive two-digit number has tens' digit w and units' digit x , what is the value of w x ?
A two-digit number 23 is written with its place values. The digit 2 is at tens place and stands for 20 and digit 3 is at ones place and stands for 3.
A two-digit number is a two-digit number that starts with 10 and ends with 99. We can't start from scratch. In that case, it is assumed to be a single digit. The tens digit can be any number from 1 to 9. For example, 45, 78, 12 are two digit numbers.
The digit value is the position of each digit in the number. When talking about single-digit numbers, there is only one place value. When it comes to two-digit numbers, there are two digit values, 1 and 10.
For example:
a.) 33 ⇒ 3 tens + 3 ones = (3 × 10) + (3 × 1) = 30 + 3 = 33
b.) 18 ⇒ 1 tens + 8 ones = (1 × 10) + (8 × 1) = 10 + 8 = 18
c.) 27 ⇒ 2 tens + 7 ones = (2 × 10) + (7 × 1) = 20 + 7 = 27
