a report on high school graduation stated that 85 percent of high school students graduate. suppose 3 high school students are randomly selected from different schools. what is the probability that exactly one of the three graduates? question 4 options: 0.019 0.003 0.614 0.057 0.850
The probability that exactly one of three randomly selected high school students graduate, given an 85% graduation rate, is 0.057. This calculation was based on the combination formula and the binomial probability distribution.
This problem involves calculating the probability of a specific outcome (exactly one of the three students graduating) in a binomial distribution. We know that the probability of any one student graduating is 0.85, so the probability of one student not graduating is 0.15. Using the binomial probability formula, we can calculate the probability of exactly one student graduating out of three as:
P(X = 1) = (3 choose 1) * (0.85)^1 * (0.15)^2 = 3 * 0.85 * 0.0225 = 0.057
Therefore, the answer is 0.057, or approximately 5.7%. This means that if we randomly select three high school students from different schools, there is a 5.7% chance that exactly one of them will graduate.

For a period of time, an island's population grows at a rate proportional to its population. If the growth rate is 3.8% per year and the current population is 1543, what will the population be 5.2 years from now
The population after 5.2 years is 1880.8, or about 1881 people.
We are given that;
Growth rate = 3.8%
Now,
Find an equation relating the variables introduced in step. We can use the formula for exponential growth:
\($$P(t) = P(0)e^{rt}$$\)
where P(t) is the population after t years, P(0) is the initial population, e is a constant approximately equal to 2.71828183..., and r is the growth rate per year.
Substitute all known values into the equation from step 4, then solve for the unknown quantity. We know that P(0) = 1543, r = 0.038, and t = 5.2. Substituting these values into the equation for P(t), we get:
\($$P(5.2) = P(0)e^{rt}$$$$P(5.2) = 1543e^{0.038 \times 5.2}$$$$P(5.2) \approx 1543e^{0.1976}$$$$P(5.2) \approx 1543 \times 1.2184$$$$P(5.2) \approx 1880.8$$\)

The Surf City water market features competitive conditions (widespread access to mature technologies, free entry, an undifferentiated product). The supply and demand curves are given bySupply: ! = 5P − 5 Demand: " = 400 − 10P(c) [5 points] A new desalination technology is discovered by researchers at Surf City University that allows the production of unlimited clean water from sea water at a cost of $8. The generous researchers of SCU license the technology for free to anybody who wants to use it. What will be the market supply curve after the introduction of the technology, assuming there are no fixed costs of entering the market with the new technology? What will the equilibrium price and quantity be after the technology is introduced?
The required answer is he equilibrium price will be $8, and the equilibrium quantity will be 320 units.
After the introduction of the new desalination technology, the market supply curve will shift to the right, since firms will be able to produce more water at a lower cost. The new supply curve will be given by:
! = 5P + (8 * quantity) - 5
This is because the cost of producing each unit of water has now increased by $8, but the supply function remains the same. specifically general equilibrium theory, a perfect market, also known as an atomistic market, is defined by several idealizing conditions, collectively called perfect competition, or atomistic competition. In theoretical models where conditions of perfect competition hold, it has been demonstrated that a market will reach an equilibrium in which the quantity supplied for every product or service, including labor, equals the quantity demanded at the current price
To find the equilibrium price and quantity, we need to set the new supply curve equal to the demand curve:
400 - 10P = 5P + (8 * quantity) - 5
Simplifying and solving for P:
15P = 405 + 8Q
P = 27 + (8/15)Q
Next, we substitute this expression for P into either the demand or supply curve and solve for Q. Let's use the demand curve:
400 - 10(27 + (8/15)Q) = Q + 5
Simplifying:
Q = 60
Therefore, the equilibrium quantity is 60 units of water, and the equilibrium price can be found by plugging this quantity into the expression for P:
P = 27 + (8/15)(60) = $43.20
So the equilibrium price is $43.20 per unit of water.
To find the market supply curve after the introduction of the new desalination technology and the equilibrium price and quantity, follow these steps:
Step 1: Determine the new supply curve.
Since the desalination technology allows for unlimited water production at a cost of $8, the new supply curve will be a horizontal line at P = $8. This is because suppliers will be willing to supply any quantity of water at that price.
Step 2: Find the new equilibrium price and quantity.
To find the new equilibrium, we need to determine where the new supply curve intersects the demand curve. The demand curve is given by Qd = 400 - 10P. To find the intersection, set the price P equal to $8 in the demand equation:
Qd = 400 - 10(8)
Qd = 400 - 80
Qd = 320
So, at the equilibrium price of $8, the quantity demanded is 320 units.
In conclusion, the market supply curve after the introduction of the new desalination technology will be a horizontal line at P = $8. The equilibrium price will be $8, and the equilibrium quantity will be 320 units.

You construct an open box from a square piece of material by cutting six-centimeter (denoted by h ) squares from the corners and turning up the sides (see figure). (4) The volume of the bex is 864 cubic centimeters. Find the dimensions (in cm) of the square piece of material that you use to construct the box. Cmx
Based on this calculation, it seems that the given dimensions for the box are not feasible. Double-checking the dimensions and calculations is recommended.
To find the dimensions of the square piece of material used to construct the box, we need to consider the volume of the box and the dimensions of the cut-out corners.
Let's start by understanding the shape of the box. From the information given, we know that the box is open, which means it doesn't have a top. The sides of the box are formed by turning up the cut-out corners. Since the corners are square and have a side length of 6 cm, each side of the box has a height of 6 cm.
The volume of the box is given as 864 cubic centimeters. To find the dimensions of the square piece of material, we need to determine the length and width of the base of the box.
Let's denote the length of the base as L and the width as W. Since the corners are cut out from the material, the dimensions of the base will be reduced by twice the length of the cut-out corners, which is 2h.
So, the length of the base will be L - 2h and the width will be W - 2h.
The volume of a rectangular box is given by the formula V = L × W × H, where H is the height of the box. In this case, the height is 6 cm.
Substituting the values into the formula, we have:
864 = (L - 2h) × (W - 2h) × 6
Simplifying the equation, we have:
144 = (L - 2h) × (W - 2h)
Now, we need to find two numbers that multiply to 144 and represent the length and width of the base. We can use factors of 144 to find possible values for L and W.
The factors of 144 are:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
Let's consider one possible set of dimensions: L = 16 and W = 9.
Substituting these values into the equation, we have:
144 = (16 - 2h) × (9 - 2h)
Expanding the equation, we get:
144 = 144 - 34h + 4h^2
Simplifying further, we have:
4h^2 - 34h = 0
Factoring out h, we have:
h(4h - 34) = 0
From this equation, we can see that h = 0 or h = 34/4 = 8.5.
Since h represents the side length of the cut-out corners, we cannot have h = 0 as it would mean there are no corners. So, the only valid value for h is 8.5 cm.
Now, we can find the dimensions of the square piece of material:
Length = L - 2h = 16 - 2(8.5) = 16 - 17 = -1 cm (not a valid length)
Width = W - 2h = 9 - 2(8.5) = 9 - 17 = -8 cm (not a valid width)
Based on this calculation, it seems that the given dimensions for the box are not feasible. Double-checking the dimensions and calculations is recommended.

The most likely correlation coefficient for the set of data (-0.91, -0.35, 0.35, 0.91) is either -0.91 or 0.91.
The correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges between -1 and 1, where -1 indicates a strong negative correlation, 1 indicates a strong positive correlation, and 0 indicates no correlation.
In the given set of data, we have two negative values (-0.91 and -0.35) and two positive values (0.35 and 0.91). The absolute values of all the numbers are the same, indicating a consistent strength of correlation. Since the data values are symmetrically distributed around 0, it suggests a linear relationship without any apparent bias towards positive or negative values.
Therefore, the most likely correlation coefficient for this set of data is either -0.91 or 0.91, as both values represent a strong linear correlation without specifying a particular positive or negative direction.

To obtain and interpret the quartiles, we first need to arrange the data in ascending order:
10, 12, 13, 15, 16, 17, 18, 18, 21, 22, 22, 23, 25, 26, 28, 29, 32, 36, 42, 56, 61
a. Quartiles divide a dataset into four equal parts. To find the quartiles, we need to determine three values: Q1, Q2 (also known as the median), and Q3.
In this case, since we have 21 data points, the median (Q2) will be the average of the 11th and 12th values. Thus, Q2 = (22 + 23) / 2 = 22.5.
To find Q1, we take the median of the lower half of the data. As there are 10 values below the median, Q1 will be the average of the 5th and 6th values: Q1 = (16 + 17) / 2 = 16.5.
Similarly, to find Q3, we take the median of the upper half of the data. With 10 values above the median, Q3 will be the average of the 15th and 16th values: Q3 = (28 + 29) / 2 = 28.5.
Therefore, the quartiles are as follows:
Q1 = 16.5
Q2 = 22.5
Q3 = 28.5
Interpretation:
Q1 represents the 25th percentile, which means that 25% of the data values fall below this value. In this case, it indicates that 25% of the patients had a length of stay of 16.5 days or less.
Q2 (the median) represents the 50th percentile, indicating that 50% of the data values are below this value. Here, it means that half of the patients had a length of stay of 22.5 days or less.
Q3 represents the 75th percentile, signifying that 75% of the data values are below this value. In this context, it suggests that 75% of the patients had a length of stay of 28.5 days or less.
The quartiles provide insights into the distribution of the data and help identify the spread and central tendency of the length of stay in this particular sample of patients.
