5.66. what is the probability that an irs auditor will catch only 2 income tax returns with illegitimate deduc-tions if she randomly selects 5 returns from among 15 returns, of which 9 contain illegitimate deductions?
The probability that an irs auditor will catch only 2 income tax returns with illegitimate deduc-tions = 0.24
Let us assume that X be the number of returns containing illegitimate deductions in the sample.
Here, X has a hypergeometric distribution.
We need to find the probability that an IRS auditor will catch only 2 income tax returns with illegitimate deduc-tions.
Here, N = 15, r = 9, n = 5
So, P (X = 2) = (⁹C₂ × ⁶C₃) / (¹⁵C₅)
We know that the combination formula:
⁹C₂ = 9! / (2! × 7!)
= 36
⁶C₃ = 6! / (3! × 3!)
= 20
¹⁵C₅ = 15! / (5! 10!)
= 3003
P (X = 2) = (⁹C₂ × ⁶C₃) / (¹⁵C₅)
= (36 × 20) / (3003)
= 0.24
Therefore, the required probability is: 0.24

For each of the figures write an absolute value equation that has the following solution set.
To write an absolute value Equation for a given solution set, we need to use the appropriate formula depending on the nature of the solution set.
To write an absolute value equation for a given solution set, we need to first understand what absolute value is. Absolute value is a mathematical function that returns the positive value of a given number, irrespective of its sign. For example, the absolute value of -5 is 5, and the absolute value of 5 is also 5. Now, let's consider the given figures and their respective solution sets:
Figure 1: The solution set for this figure is {2, -2}. To write an absolute value equation for this solution set, we can use the formula |x| = a, where a is the value of the solution set. Therefore, the absolute value equation for this figure is |x| = 2.
Figure 2: The solution set for this figure is {5}. To write an absolute value equation for this solution set, we can use the formula |x - b| = a, where b is the midpoint of the solution set and a is the distance from the midpoint to one of the solutions. Therefore, the absolute value equation for this figure is |x - 5| = 0.
Figure 3: The solution set for this figure is {-3, 3}. To write an absolute value equation for this solution set, we can again use the formula |x| = a, where a is the value of the solution set. Therefore, the absolute value equation for this figure is |x| = 3.
In conclusion, to write an absolute value equation for a given solution set, we need to use the appropriate formula depending on the nature of the solution set.

times the length. Find the width.
O 10
O 12
O 15
O 14
Based on the above, the width of the rectangle is 10.
What is the width?Let's use "w" to represent the width and "l" to represent the length of the rectangle.
From the problem, we know that the area of the rectangle is 40, so we can write:
Area = length × width
40 = l × w
We also know that the width is 2 less than 3 times the length, so we can write:
width = 3l - 2
Now we can substitute this expression for "w" in the equation for the area: 40 = l × (3l - 2)
Expanding the right side gives: 40 = 3l² - 2l
Rearranging and dividing by 2 gives:
3l²- 2l - 40 = 0
(3l + 10)(l - 4) = 0
Therefore, l = 4 (because the length cannot be negative), and we can find the width using the expression we found earlier:
width = 3l - 2
width = 3(4) - 2
width = 10
So the width of the rectangle is 10. Therefore, the answer is 10.

A farmer wants to estimate the number of moles in a local area she catches and tags 30 moles, then releases them back into the local area a few days later the farmer catches another sample of the miles and finds that half of them have a tag estimate the total number of moles in the local area
The estimated total number of moles in the local area is 4.
The farmer needs to use the capture-recapture method to estimate the total number of moles in the local area. This involves tagging a population sample, releasing them back into the population, and then capturing another sample to determine the proportion of tagged individuals in the second sample. Using this proportion, the total population can be estimated using the following formula:
total population = (number in first sample * number in the second sample) / number of tagged individuals in the second sample
In this case, the farmer tagged 30 moles in the first sample and found that half of the second sample had tags. We can use these values to estimate the total number of moles:
total population = (30 * 2) / 15
total population = 4
Note that the actual population size may be larger or smaller than this estimate due to factors such as migration, birth, and death rates.
To correctly estimate the number of moles in a substance, the farmer needs to use the grams to moles formula, which is:
n = m / M
where n is the number of moles, m is the mass of the substance in grams, and M is the molar mass in grams per mole . To calculate the molar mass of a substance, the farmer can sum the molar masses of its component atoms

Use regression to find an equation for the path of the golf ball?
Use matrices to find the equation for the golf balls path?
The assumptions include that the path of the ball can be modeled by a parabolic function, that data on the trajectory of the ball is needed, and that matrices can be used to solve for the constants a, b, and c. Finally, the inverse of the matrix can be computed using matrix algebra.
What is a matrix?A matrix is a rectangular array of letters, numbers, or expressions in mathematics that are organized in rows and columns. In addition to representing and transforming data in statistics, physics, and computer science, matrices are also used to represent and convert linear equations and transformations in linear algebra.
We need to make some assumptions and approximations in order to develop an equation for the flight of the golf ball because the actual path of the ball is influenced by a number of variables, including wind, temperature, humidity, and spin. The idea that a parabolic function may simulate the ball's trajectory is one that is frequently held.
We would need information on the ball's trajectory, such as height and distance at various points along the trip, in order to perform regression. Regression analysis cannot be used to derive an equation for the trajectory of the golf ball in the absence of this data.
To use matrices, we can set up a system of equations based on the parabolic function:
[tex]y = ax^2 + bx + c[/tex]
where x is the distance traveled by the ball, y is the height of the ball, and a, b, and c are constants to be determined.
We can set up three equations based on the following assumptions:
At the starting point (x=0), the height of the ball is zero.
At the point where the ball hit the tree (x = d), the height of the ball is the height of the tree (90 feet).
At the landing point on the green (x = D), the height of the ball is zero.
Using these assumptions, we can set up the following system of equations:
c = 0 (from assumption 1)
[tex]ad^2 + bd + c[/tex] = 90 (from assumption 2)
[tex]aD^2 + bD + c[/tex] = 0 (from assumption 3)
To solve for the constants a, b, and c, we can use matrix algebra to write the system in matrix form:
[tex][0 0 1] [c] [0][/tex]
c[tex][d^2 d 1] * [b][/tex] = [90]
[tex][D^2 D 1][/tex] [a] [0]
Multiplying the matrices, we get:
[0 0 1] [c] [0]
[tex][d^2 d 1][/tex] * [b] = [90]
[tex][D^2 D 1][/tex] [a] [0]
Simplifying, we get:
[c] [0]
[b] = [90] * [tex][d^2 d 1]^-1 * [d^2 d 1][/tex]
[a] [0]
where the inverse of the matrix [tex][d^2 d 1][/tex] can be computed using matrix algebra. Once we have the values of a, b, and c, we can plug them into the equation [tex]y = ax^2 + bx + c[/tex] to get the equation for the path of the golf ball.

What is the surface area of a right circular cone with a diameter of 8 m, height of 6.9 m, and a slant height of 18.5 m? Round your answer to the nearest whole.
The surface area of a right circular cone can be found using the formula:
A = πr²+ πrl
where r is the radius of the base, l is the slant height, and π is approximately 3.14159.
In this case, the diameter of the base is 8 m, so the radius is 4 m. The slant height is 18.5 m. The height is not needed for this calculation.
Substituting the given values, we get:
A = π(4 m)² + π(4 m)(18.5 m)
A = π(16 m²) + π(74 m²)
A = π(90 m²)
Using the approximation π ≈ 3.14159, we get:
A ≈ 282.74 m²
Therefore, the surface area of the right circular cone is approximately 283 m² rounded to the nearest whole.

The median is the best measure of center because there are outliers present.
Using the median, which is not affected by outliers, would provide a better representation of the typical or central value of the data.
What is median?
Median is a measure of central tendency that represents the middle value in a dataset when the values are arranged in order of magnitude. To find the median, you need to arrange the values in order from smallest to largest and then find the middle value.
Based on the given information, the median is the best measure of center because there are outliers present. The reason for this is because the presence of outliers can greatly affect the mean and make it a less representative measure of central tendency.
In this case, the dots above 6, 7, and 3 may be considered as outliers since they are far from the other data points.
Therefore, using the median, which is not affected by outliers, would provide a better representation of the typical or central value of the data.

x² + y² + 4x + 6y - 3 = 0 equation represents the general form a circle with a center at (â€"2, â€"3) and a diameter of 8 units.
The equation of a circle with center (h, k) and radius r can be written in the form (x - h)² + (y - k)² = r².
Given a center of (-2, -3) and a diameter of 8 units, first find the radius, which is half of the diameter:
r = 8 / 2 = 4
Now, substitute the center coordinates and radius into the equation:
(x - (-2))² + (y - (-3))² = 4²
(x + 2)² + (y + 3)² = 16
Now, expand the equation to get the general form:
(x² + 4x + 4) + (y² + 6y + 9) = 16
x² + 4x + y² + 6y + 4 + 9 - 16 = 0
Combine like terms to get the final equation:

What is the probability that Karen's second card will be a black card?
The probability that Karen's second card will be a black card is 3/650.
How to determine probability?After Sandra deals Karen a red seven, there are 51 cards remaining in the deck, of which 26 are black cards. So the probability of Karen drawing a black card on her second draw depends on whether or not the first card she drew was black or red:
If the first card Karen drew was black, then there are 25 black cards left in the deck out of 50 cards, since one card has already been drawn. So the probability of Karen drawing a black card on her second draw is 25/50 = 1/2.
If the first card Karen drew was red, then there are still 26 black cards left in the deck out of 50 cards, since one card has already been drawn. So the probability of Karen drawing a black card on her second draw is 26/50 = 13/25.
Since there are 26 red cards and 26 black cards in a standard deck of playing cards, the probability of Karen being dealt a red seven by Sandra is 2/52 = 1/26.
To find the overall probability of Karen being dealt a red seven and then drawing a black card on her second draw, multiply the probability of these two events occurring:
P(red seven and black card) = P(red seven) × P(black card on second draw | red seven)
P(red seven) = 1/26
P(black card on second draw | red seven) = 13/25
P(red seven and black card) = (1/26) × (13/25) = 13/650
Therefore, the probability of Karen's second card being a black card, given that Sandra dealt her a red seven, is 13/650.

As given, a machine that is programmed to package 1.60 pounds of cereal is being tested for its accuracy in a sample of 40 cereal boxes, the sample mean filling weight is calculated as 1.62 pounds. The population standard deviation is known to be 0.06 pounds. We are required to find the 95% confidence interval for the mean. Here are the steps to solve this problem:
The formula to find the confidence interval is as follows;
Lower limit = x - zα/2 (σ/√n)
Upper limit = x + zα/2 (σ/√n)
Where,
x= sample mean
zα/2 = z-value of the level of significance
σ = population standard deviation
n = sample size
We are given;
x = 1.62 pounds
σ = 0.06 pounds
n = 40
We need to find the z-value of the level of significance, which can be found using the z-table or by using the calculator.Using the z-table, we get the z-value at 95% confidence interval as zα/2 = 1.96
Substituting the values, we get
Lower limit = 1.62 - 1.96(0.06/√40)
Upper limit = 1.62 + 1.96(0.06/√40)
Lower limit = 1.6048, Upper limit = 1.6352

han pennies. There are 2 more nickels than pennies How much money does the bag contain?
The bag contains $4.60 in coins.
What are coins?
Let's use P, N, D, and Q to represent the number of pennies, nickels, dimes, and quarters, respectively, in the bag.
We know that the total number of coins is 50, so:
P + N + D + Q = 50
We also know that 10% of the coins are pennies, so:
P = 0.1(50)
P = 5
There are 2 more nickels than pennies, so:
N = P + 2
N = 5 + 2
N = 7
Now we can use this information to find the number of dimes and quarters. Since there are 50 coins in total, we can substitute the values we have found for P and N into the first equation:
P + N + D + Q = 50
5 + 7 + D + Q = 50
12 + D + Q = 50
D + Q = 38
We also know the values of P and N, so we can find the total value of all the coins in the bag:
Total value = (value of pennies) + (value of nickels) + (value of dimes) + (value of quarters)
Total value = (5 cents x 5) + (7 cents x 5) + (10 cents x D) + (25 cents x Q)
Total value = 25 + 35 + 10D + 25Q
We can substitute D + Q = 38 into this equation to get:
Total value = 25 + 35 + 10(D + Q)
Total value = 60 + 10(38)
Total value = 460 cents, or $4.60
Therefore, the bag contains $4.60 in coins.
