(a) The probability that this genetic disease can be present is that at least someone in the town is 2.8% of the total population.
To compute the possibility that at least one person in town has the sickness, we may first calculate the probability that no one in town has the disease and then deduct that from 1. The probability that no one in the town has the disease is calculated by binomial distribution formula.
P(X ≥ 1) = 1 - P(X = 0)
where X is the number of people in the town with the disease.
P(X = 0) is the probability that nobody in the town has the disease. When we calculate P(X = 0) as:
P(X = 0) = (15000 chooses 0) * (1/5000)⁰ * (4999/5000)¹⁵⁰⁰⁰
P(0) ≈0.972
The probability that at least one person in the town has the disease is:
P(X ≥ 1) = 1 - P(X = 0)
≈ 1 - 0.972
P(X ≥ 1) ≈ 0.028
As a result, there is a 2.8% probability that at least one person in town has the condition.
(b) The probability that this genetic disease can be present is that at most 2 people in the town is 99.9% of the total population.
To compute the probability that no more than two persons in the town have the sickness, we must sum the probabilities of none, one, and two people having the condition. The binomial distribution gives the chance that precisely x persons have the disease:
P(x) = (n choose x) * pˣ * (1-p)ⁿ⁻ˣ
where n is the sample size (15,000)
p is the illness probability (1/5000)
(n pick x) is the binomial coefficient, which is the number of ways to select x items from a collection of n items.
We can calculate using this formula:
P(0) = (15000 choose 0) * (1/5000)⁰ * (4999/5000)¹⁵⁰⁰⁰
P(0) ≈ 0.972
P(1) = (15000 choose 1) * (1/5000)¹ * (4999/5000)¹⁴⁹⁹⁹
P(1) ≈ 0.027
P(2) = (15000 choose 2) * (1/5000)² * (4999/5000)¹⁴⁹⁹⁸
P(2) ≈ 0.001
So the probability of at most 2 people in the town having the disease is:
P(0) + P(1) + P(2) ≈ 0.999
As a result, there is a 99.9% probability that at most 2 people in the town have the disease.
(c) The expected number of people in the town who have the disease is 3 among the 15000 people.
The mean of the binomial distribution gives the expected amount of persons in the town who have the disease.
E(X) = n*p
where X is the random variable representing the number of people in the town with the disease.
Substituting n = 15,000 and p = 1/5000, we get:
E(X) = 15,000 * (1/5000) = 3
E(X) = 3
So we would expect about 3 people in the town to have the disease among the total population.
(d) The variance for the number of people in the town with the disease is 2.998 among the total population.
The binomial distribution's variance is given by:
Var(X) = n*p*(1-p)
considering n = 15,000 and p = 1/5000, we get:
Var(X) = 15,000 * (1/5000) * (4999/5000)
Var(X) ≈ 2.998
So the variation in the number of persons in the town infected with the illness is around 2.998.

a random sample of 380 found that 67% of the readers owned a personal computer. find the value of the test statistic. round your answer to two decimal places.
The value of the test statistic is 6.51.
The test statistic for this problem can be calculated using the formula:
z = (p - P) / √(P * (1 - P) / n)
Where p is the sample proportion (0.67 in this case), P is the hypothesized population proportion (we don't know this value, so we assume it to be 0.5 for a two-tailed test), n is the sample size (380), and z is the standard normal distribution value corresponding to the level of significance.
Plugging in the values, we get:
z = (0.67 - 0.5) / √(0.5 * (1 - 0.5) / 380) = 6.51
So the value of the test statistic is 6.51.
The test statistic is a measure of how far the sample proportion deviates from the hypothesized population proportion under the null hypothesis. In this case, we assume that the population proportion is 0.5 (since we have no reason to believe otherwise), and we calculate the probability of observing a sample proportion of 0.67 or greater assuming this null hypothesis is true.

Rick is building a sandbox for his cousins in the shape of a parallelogram. When drawn on a coordinate plane, the sandbox has vertices at (-4,0), (-2,6), (4,0), and (2,-6). If every unit represents a foot, what area does the sandbox cover?
~a.) 24ft²
~b.) 36ft²
~c.) 48ft²
~d.) 64ft²
The area of the sandbox of parallelogram shape is approximately 22.47 square feet. Rounded to the nearest integer, the answer is (a) 24ft².
What is a parallelogram?A parallelogram is a quadrilateral with two pairs of parallel sides. Opposite sides of a parallelogram are equal in length and parallel to each other. Additionally, opposite angles of a parallelogram are congruent (i.e., have the same measure).
According to the given informationWe can choose any side of the parallelogram as the base, and the distance from that side to the opposite side as the height. Let's choose the side between (-4,0) and (-2,6) as the base. The length of this side is the distance between these two points:
√[(-2-(-4))² + (6-0)²] = √40 = 2√10
The height of the parallelogram is the distance between the line containing (-2,6) and (4,0) and the point (2,-6). We can find the equation of the line containing (-2,6) and (4,0) by finding the slope and y-intercept:
Slope: (0-6)/(4-(-2)) = -6/6 = -1
Y-intercept: y = mx + b -> 0 = (-1)(4) + b -> b = 4
Therefore, the equation of the line is y = -x + 4. We can find the distance between this line and the point (2,-6) by substituting x = 2 into the equation and finding the corresponding y-value:
y = -x + 4 = -2
The distance between the line and the point (2,-6) is the absolute value of the difference between the y-coordinate of the point and the y-coordinate of the line:
|(-6) - (-2)| = 4
Therefore, the height of the parallelogram is 4 feet.
The area of the parallelogram is then:
A = base x height = (2√10) x 4 = 8√10
Rationalizing the denominator, we get:
A = 8√10 x √10/√10 = 80/√10 = 80√10/10 = 8√10
Therefore, the area of the sandbox is approximately 22.47 square feet. Rounded to the nearest integer, the answer is (a) 24ft².

A rectangular prism with dimensions of 5 yards by 5 yards by 3 and one half yard.
What is the volume of the prism?
Therefore, the volume of the rectangular prism is 87.5 cubic yards.
What is prism?A prism is a transparent object, usually made of glass or plastic, that refracts or bends light as it passes through it. It has at least two flat surfaces, called faces, that are usually parallel and rectangular in shape, and two non-parallel faces, called bases, which are usually triangular in shape. When light enters a prism, it is refracted, or bent, as it passes through the prism and is separated into its component colors, creating a rainbow effect. Prisms are often used in optics and science experiments to study the properties of light, such as its wavelength and polarization. They are also commonly used in optical instruments such as binoculars, telescopes, and cameras to help focus and direct light.
The volume V of a rectangular prism is given by the formula:
V = length x width x height
In this case, the length is 5 yards, the width is also 5 yards, and the height is 3- and one-half yard.

According to the information, the surface area of the first prism is 795 cm², sencond prism is 843 in², and the cylinder is 3775.87 mm²
How to find the surface area of two triangular prims?To find the surface area of two triangular prisms, we need to add the surface area of each prism. We can use the formula we found in the previous question to calculate the surface area of each triangular prism:
Surface area of first triangular prism = 2(0.5 x base x height) + perimeter x height
where base is the width of the triangular face, height is the height of the triangular face, and perimeter is the sum of the lengths of the three sides of the triangular face.
In this case, the first triangular face has a base of 9 cm, a height of 16 cm, and a perimeter of (9+15+12)=36 cm. Therefore, the area of each triangular face is:
0.5 x 9 cm x 16 cm = 72 cm²
The rectangular faces have dimensions of 9 cm x 15 cm, 15 cm x 16 cm, and 9 cm x 16 cm. Therefore, the area of each rectangular face is:
9 cm x 15 cm = 135 cm²
15 cm x 16 cm = 240 cm²
9 cm x 16 cm = 144 cm²
The total surface area of the first triangular prism is:
2(72 cm²) + (135 cm² + 240 cm² + 144 cm²) = 795 cm²
Similarly, for the second triangular prism, we have:
Surface area of second triangular prism = 2(0.5 x base x height) + perimeter x height
where base is the width of the triangular face, height is the height of the triangular face, and perimeter is the sum of the lengths of the three sides of the triangular face.
In this case, the second triangular face has a base of 8 in, a height of 15 in, and a perimeter of (8+15+20)=43 in. Therefore, the area of each triangular face is:
0.5 x 8 in x 15 in = 60 in²
The rectangular faces have dimensions of 8 in x 21 in, 15 in x 21 in, and 8 in x 15 in. Therefore, the area of each rectangular face is:
8 in x 21 in = 168 in²
15 in x 21 in = 315 in²
8 in x 15 in = 120 in²
The total surface area of the second triangular prism is:
2(60 in²) + (168 in² + 315 in² + 120 in²) = 843 in²
Therefore, the surface area of two triangular prisms is:
795 cm² + 843 in² = 795 cm² + (843 in² x 6.452 cm²/in²) ≈ 5508 cm²
For the cylinder, we can use the formula we found in the previous question to calculate the surface area:
Surface area of cylinder = 2πr² + 2πrh
where r is the radius of the circular face, h is the height of the cylinder.
In this case, the radius is 14 mm and the height is 29 mm. Therefore, the surface area of the cylinder is:
2π(14 mm)² + 2π(14 mm)(29 mm) = 2π(14 mm)(43 mm) ≈ 3775.87 mm²
Therefore, the surface area of two triangular prisms and a cylinder is approximately:
5508 cm² + 3775.87 mm² = 5508 cm² + (3775.87 mm² x 0.01 m²/mm²) ≈ 5885.47 cm²

This is because the process of transforming scores into z-scores involves subtracting the mean of the population and dividing by the standard deviation, which effectively standardizes the data to have a mean of 0 and a standard deviation of 1. When all the scores in a population are transformed into z-scores, the mean of the complete set of z-scores will be 0 and the standard deviation will be 1. This is because z-scores represent the number of standard deviations a value is from the mean, and the transformation standardizes the distribution.

a local politician is concerned that a program for the homeless in the city is discriminating against blacks and other minorities. the following data were taken from a random sample of black and white homeless people. race black white received services yes 6 7 13 no 4 9 13 10 16 26 a. is there a statistically significant relationship between race and whether the person received services from the program? b. compute column and row percentages for the table to determine the pattern of the relationship. which group was more likely to receive services in the sample? interpret both the column and row percentages that you have obtained.
(a) There is no statistically significant relationship between race and receiving services from the program.
(b) Black homeless people were more likely to receive services (60%) than white homeless people (43.75%).
How to find the relationship between race and receiving services?a. To test whether there is a statistically significant relationship between race and whether the person received services from the program, we can use a chi-squared test of independence.
The null hypothesis is that there is no relationship between race and receiving services, and the alternative hypothesis is that there is a relationship.
Using a chi-squared calculator, we obtain a chi-squared statistic of 0.267 and a p-value of 0.605. Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis and conclude that there is no statistically significant relationship between race and receiving services from the program.
How to find more likely to receive services?b. To compute column and row percentages, we can first calculate the total number of black and white homeless people who received services and who did not receive services:
Black homeless people who received services: 6/10 = 60%Black homeless people who did not receive services: 4/10 = 40%White homeless people who received services: 7/16 = 43.75%White homeless people who did not receive services: 9/16 = 56.25%We can also calculate the percentage of all homeless people who received services or did not receive services, by adding up the numbers in each column:
Percentage of homeless people who received services: 13/26 = 50%Percentage of homeless people who did not receive services: 13/26 = 50%In the sample, black homeless people were more likely to receive services (60%) than white homeless people (43.75%).

at a booth at the school carnival in past years, they've found that 22% of students win a stuffed toy ($3.60), 16% of students win a jump rope ($1.20), and 6% of students win a t-shirt ($7.90). the remaining students do not win a prize. if 150 students play the game at the booth, how much money should the carnival committee expect to pay for prizes for that booth?: *
For a percentage data of students who play the different game and win the prize, the expected amount to pay for prizes for that booth by the carnival committee is equals to the $218.70.
We have a booth of school carnival in past years, The percentage of students win a stuffed toy = 22%
The percentage of students win a jump rope = 16%
The percentage of students win a t-shirt
= 6%
The winning amount for stuffed toy game = $ 3.60
The winning amount for jump rope game = $1.20
The winning amount for t-shirt game
= $7.90
The remaining students do not win a prize. Now, total number of students play the game at the booth = 150
So, number of students who win stuffed toy = 22% of 150 = 33
Number of students who win jump rope = 16% of 150 = 24
Number of students who win stuffed toy
= 6% of 150 = 9
For determining the expected pay using the simple multiplication formula. Total expected pay for prizes for that booth is equals to the sum of resultant of multiplcation of number of students who play a particular game into pay amount for that game. That is total excepted pay in dollars = 3.60 × 33 + 1.20 × 24 +7.90 × 6
= 218.7

The base, lateral area and surface area is B = 96 cm², L = 499.2 cm²,S = 691.2 cm²
What is Lateral Area ?The lateral area for the triangular prism is the sum of all three areas. Thus, the formula for lateral area of triangular prism, Lateral surface area of triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h.
To find the lateral area (L) of this solid, we need to calculate the area of the four rectangles that make up the sides of the solid. Since each rectangle has a height of 10.4 cm and a width of 12 cm, the area of one rectangle is:
A = 10.4 cm * 12 cm = 124.8 cm²
Since there are four rectangles, the total lateral area is:
L = 4 * A = 4 * 124.8 cm² = 499.2 cm²
To find the surface area (S) of the solid, we need to add the lateral area to the area of the two circular bases. The base area is given as 96 cm², so the area of both bases is:
A = 2 * 96 cm² = 192 cm²
Therefore, the total surface area is:
S = L + A = 499.2 cm² + 192 cm² = 691.2 cm²
Rounding to the nearest tenth, we have:
B = 96 cm²
L = 499.2 cm²
