1. Net income after deductions: $1,880.00 - $487.48 = $1,392.52. 2. your total realized income for that month would be $2,574.00. 3. the total income for the second month would be $2,574.00 + $822.50 = $3,396.50.
Describe income ?Income refers to the money earned or received by an individual or an entity in exchange for goods or services provided or as compensation for work done. It can come from various sources such as employment, investments, rental properties, or business activities. Income is often used to pay for expenses, such as bills, food, housing, transportation, and other necessities. It is also commonly saved or invested to build wealth and achieve long-term financial goals.
1. Assuming a month has 4 weeks, your total realized income for one month would be:
40 hours/week x $11.75/hour x 4 weeks = $1,880.00
Your fixed expenses for one month would be:
Rent: $657.00
Telephone: $56.34
Groceries: $56.00 x 4 = $224.00
Clothing: $106.00
Water & Electric: $98.87
Total fixed expenses: $1,142.21
Your discretionary expenses for one month would be:
Weekly Dinner & Movie: $40.00 x 4 = $160.00
Total discretionary expenses: $160.00
Therefore, your total expenses for one month would be:
Fixed expenses + discretionary expenses = $1,142.21 + $160.00 = $1,302.21
To calculate your net income after deductions, we need to first calculate the amount of deductions:
FICA: 7.65% of $1,880.00 = $143.88
Federal tax withholding: 10.75% of $1,880.00 = $202.60
State tax withholding: 7.5% of $1,880.00 = $141.00
Total deductions: $487.48
Net income after deductions: $1,880.00 - $487.48 = $1,392.52
2. If you work 20 hours of overtime the next month and are paid 1.5 times your regular rate, your total realized income for that month would be:
(40 hours x $11.75/hour x 4 weeks) + (20 hours x $11.75/hour x 1.5 x 4 weeks) = $2,574.00
Your fixed expenses would remain the same, but your discretionary expenses may increase due to the additional income.
3. If you eliminated your discretionary expenses of $160.00 per month, you could put that amount towards savings each month. This would increase your savings by $1,920.00 per year.
To calculate the income for the first 40 hours of work, we simply multiply the hourly rate by the number of hours worked:
40 hours x $11.75/hour = $470.00
To calculate the income for the additional 20 hours of overtime at 1.5 times the regular rate, we first calculate the regular rate for the overtime hours (40 hours x $11.75/hour = $470.00), and then add 1.5 times that amount to the total:
40 hours x $11.75/hour = $470.00
20 hours x ($11.75/hour x 1.5) = $352.50
Total overtime pay = $470.00 + $352.50 = $822.50
Therefore, the total income for the second month would be $2,574.00 + $822.50 = $3,396.50.

Suppose that car accidents along a stretch of road occurs independently and are described by the Poisson distribution at a rate of 0.1 per hour. Furthermore, the number of motorcycle accidents along the same stretch of road also occurs independently and are described by the Poisson distribution at a rate of 0.05 per hour. What is the probability that there will be at most one accident in the next 2 hours?
Answers
The probability of at most one accident in the next 2 hours is 82.15%.
Let X be the number of car accidents in the next 2 hours, and Y be the number of motorcycle accidents in the next 2 hours. Both X and Y follow Poisson distributions, with rates of λX = 0.12 = 0.2 and λY = 0.052 = 0.1, respectively.
To find the probability that there will be at most one accident (either car or motorcycle) in the next 2 hours, we need to find the probability of the events {X + Y = 0} and {X + Y = 1}:
P(X + Y ≤ 1) = P(X + Y = 0) + P(X + Y = 1)
To find these probabilities, we can use the joint Poisson distribution of X and Y:
P(X = i, Y = j) = e^-(λX+λY) * (λXᵃ /a!) * (λYᵇ / b!)
where a and b are non-negative integers.
For X + Y = 0, we have:
P(X + Y = 0) = P(X = 0, Y = 0) = e⁻⁽⁰ ²⁺⁰ ¹⁾ * (0.2⁰ / 0!) * (0.1⁰ / 0!) = e⁻⁰ ³ ≈ 0.7412
For X + Y = 1, we have:
P(X + Y = 1) = P(X = 0, Y = 1) + P(X = 1, Y = 0) = e⁻⁽⁰ ²⁺⁰ ¹⁾ * (0.2⁰/ 0!) * (0.1¹/ 1!) + e⁻⁽⁰ ²⁺⁰ ¹⁾ * (0.2¹/ 1!) * (0.1⁰ / 0!) = 20.20.1*e⁻ ⁰ ³ ≈ 0.0803
Therefore, the probability of there being at most one accident (either car or motorcycle) in the next 2 hours is:
P(X + Y ≤ 1) ≈ 0.7412 + 0.0803 ≈ 0.8215
So the probability of there being at most one accident in the next 2 hours is about 82.15%.

On an average, five flood events in every 2 years are recorded at a location due to heavy rainfall. Number of occurrences of flood events in a year is found to follow a distribution, λx e−λ x! where λ is the expected number of flood events in a year. What is the probability of occurring not more than two flood events in a particular year at that location?
Answers
The probability of occurring not more than two flood events in a particular year at that location is approximately 0.546.
The given distribution is λxe-λx! where λ is the expected number of flood events in a year. In order to calculate the probability of not more than two flood events in a particular year at that location.
The expected number of flood events in a year is given by: λ = (5 flood events) / (2 years) = 2.5 flood events per year
The given distribution is:λxe-λx! = 2.5xe-2.5x!
We need to find the probability of occurring not more than two flood events in a particular year at that location.
Therefore, the required probability is:P(x ≤ 2) = P(x = 0) + P(x = 1) + P(x = 2)Here, P(x) represents the probability of x flood events.
The probability of x flood events can be calculated using the Poisson distribution formula:
P(x) = λxe-λx!Substitute λ = 2.5 and x = 0 in the above formula to get:P(0) = (2.5)0e-2.5 / 0! = e-2.5 ≈ 0.082Substitute λ = 2.5 and x = 1 in the above formula to get:P(1) = (2.5)1e-2.5 / 1! = 2.5e-2.5 ≈ 0.206Substitute λ = 2.5 and x = 2 in the above formula to get:P(2) = (2.5)2e-2.5 / 2! = 3.125e-2.5 ≈ 0.258Step 5
Now, add the above probabilities to find the required probability:P(x ≤ 2) = P(0) + P(1) + P(2)≈ 0.082 + 0.206 + 0.258 = 0.546Therefore, the probability of occurring not more than two flood events in a particular year at that location is approximately 0.546.

Animal shelters in a county need at least 15% of their animals to be adopted weekly to have room for the new animals that are brought into the various shelters. The county manager takes a random sample of shelters each week to estimate the overall proportion of animals that are adopted.

He tests the hypotheses: H0: The adoption rate is 15%, and Ha: The adoption rate is less than 15%. What is a Type I error, and what is its consequence in this context?
The manager believes the adoption rate is still 15%, when it actually has dropped below 15%. The manager will accept more animals into the shelters and will run out of room.

Step-by-step explanation:
First, we need to calculate how much flour the baker will use in 20 days:
Amount of flour used per day for 64 loaves = 64 loaves/day x 400 g/loaf = 25,600 g/day
Amount of flour used in 20 days = 25,600 g/day x 20 days = 512,000 g
Next, we need to convert the amount of flour used into kilograms:
512,000 g ÷ 1000 g/kg = 512 kg
Finally, we need to calculate the minimum number of 25 kg sacks the baker should order:
Number of 25 kg sacks = 512 kg ÷ 25 kg/sack ≈ 20.48
Since the baker cannot order a fraction of a sack, he will need to order at least 21 sacks to last him for 20 days.

How to find the how much fertilizer needed to apply in the garden?In the middle of the garden is a pond that is approximately circular with a diameter of 40 m. Therefore, the fertilizer will not be applied in the pond area.
The villagers will only apply the fertilizer in the garden area. The recommended rate of application of the fertiliser is 25 g/m².
Therefore, let's find the fertilizer required for the garden.
area of the garden to be fertilized = area of trapezium - area of a circle
area of the garden to be fertilized = 1 / 2 (a + b)h - πr²
area of the garden to be fertilized = 1 / 2 (124 + 196)135 - 3.14(20)²
area of the garden to be fertilized = 1 / 2 (320)(135) - 1256
area of the garden to be fertilized = 43200 / 2 - 1256
area of the garden to be fertilized = 21600 - 1256
area of the garden to be fertilized = 20344 m²

Answers
Answer:
I believe it's C.
Step-by-step explanation:
The correct equation of p is C. p(x) = x(x - 3)^2(2x + 7)^2. This is because the given polynomial has a zero of multiplicity 2 at x = 3, a zero of multiplicity 1 at x = 0, and a zero of multiplicity 2 at x = -7/2. Therefore, the equation of the polynomial can be written as p(x) = k(x - 3)^2(x)(2x + 7)^2, where k is some constant. Since the leading coefficient of the polynomial is 1, k = 1. Thus, we get the equation p(x) = x(x - 3)^2(2x + 7)^2.
It is option C and not A, B, or D because:
Option A, p(x)= x(x - 3)(2x + 7)^2, has only one factor of (x - 3), but the given polynomial has a factor of (x - 3) squared.
Option B, p(x) x^2(x - 3)(2x + 7), has an extra factor of x^2 that is not present in the given polynomial.
Option D, p(x)= x(x - 3)^2(2x + 7), is very close to the correct answer, but it is missing the factor of (x) that is present in the given polynomial.
Thus, the correct equation of p is C, p(x) = x(x - 3)^2(2x + 7)^2, which includes all the necessary factors and satisfies the given conditions.

The cylinder has height 10 cm.
a) What is the circumference of the
cylinder?
b) What is the radius of the cylinder?
c) What is the area of one circular
base?
d) What is the surface area of the
cylinder?
Answers
Answer:
a) The circumference of the cylinder can be found using the formula C = 2πr, where r is the radius of the circular base. Rearranging the formula, we get r = C/2π. To find the circumference, we can use the formula for the curved surface area: A = 2πrh, where h is the height of the cylinder. Substituting the given values, we get:
660 = 2πr(10)
r = 33/π
Now we can find the circumference:
C = 2πr = 2π(33/π) = 66
Therefore, the circumference of the cylinder is 66 cm.
b) The radius of the cylinder is given by r = 33/π, which we already found in part a).
c) The area of one circular base can be found using the formula A = πr^2. Substituting the value of r from part b), we get:
A = π(33/π)^2 = 1089/π
Therefore, the area of one circular base is 1089/π cm^2.
d) The surface area of the cylinder consists of the curved surface area and two circular bases. The area of one circular base was found in part c), so we just need to add the curved surface area to twice the area of one circular base:
Surface area = 2A + 2πrh
Substituting the given values, we get:
Surface area = 2(1089/π) + 2π(33/π)(10) = 2187/π + 660
Therefore, the surface area of the cylinder is 2187/π + 660 cm^2.

a hospital director is told that 32% 32 % of the treated patients are uninsured. the director wants to test the claim that the percentage of uninsured patients is under the expected percentage. a sample of 160 160 patients found that 40 40 were uninsured. find the value of the test statistic. round your answer to two decimal places.
Answers
The value of the test statistic is -1.75.
To test the claim that the percentage of uninsured patients is under the expected percentage of 32%, we can use a one-sample z-test. The null hypothesis is that the true percentage of uninsured patients is equal to 32%, while the alternative hypothesis is that the true percentage is less than 32%.
Using the sample data, we can calculate the sample proportion of uninsured patients as 40/160 = 0.25. We can then calculate the standard error of the sample proportion as sqrt[(0.32 x 0.68)/160] = 0.0385.
The test statistic can be calculated as (0.25 - 0.32)/0.0385 = -1.75.
To find the p-value associated with this test statistic, we can use a standard normal distribution table or a calculator to find the probability of a z-score less than -1.75. The p-value is approximately 0.04.
Since the p-value is less than the typical significance level of 0.05, we reject the null hypothesis and conclude that there is evidence to support the claim that the percentage of uninsured patients is under the expected percentage of 32%.
Therefore, the correct answer is -1.75, which is the calculated value of the test statistic.

A circular drum has a radius of 4.2m and a height of 3.5m. How many full
bags of wheat can be emptied if the space required for one wheat bag is
5.39m³.
Answers
he volume of the drum can be calculated as follows:
Volume of drum = πr²h
= π(4.2m)²(3.5m)
≈ 246.33 m³
To find out how many full bags of wheat can be emptied into the drum, we need to divide the volume of the drum by the volume of one wheat bag:
Number of full bags of wheat = Volume of drum ÷ Volume of one bag
= 246.33 m³ ÷ 5.39 m³
≈ 45.72
Therefore, the circular drum can hold approximately 45 full bags of wheat.
Answer: 45 Full of bags.
Step-by-step explanation:
The volume of the drum can be calculated using the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height.
V = π(4.2m)^2(3.5m)
V ≈ 246.73 m³
To find out how many bags of wheat can be emptied into the drum, we need to divide the volume of the drum by the space required for one bag:
246.73 m³ ÷ 5.39 m³/bag ≈ 45.81 bags
Since we can't have a fraction of a bag, we need to round down to the nearest whole number:
Number of bags = 45
Therefore, 45 full bags of wheat can be emptied into the drum.

The Sun is approximately 9.2661 x 10^7 miles farther than the Moon from Earth.
How to solveThe distance between the Sun and the Earth is approximately 9.29 x 10^7 miles, and the distance between the Moon and the Earth is approximately 2.389 x 10^5 miles.
To find how much farther the Sun is from the Earth than the Moon, we can subtract the distance between the Moon and the Earth from the distance between the Sun and the Earth:
9.29 x 10^7 miles - 2.389 x 10^5 miles = 9.2661 x 10^7 miles
Therefore, the Sun is approximately 9.2661 x 10^7 miles farther than the Moon from Earth.

Calculate the area of this triangle
Answers
Answer:
4.06 cm^2
Step-by-step explanation:
If you draw a line from the top vertex to intersect the base (which is 5.8 cm) at 90 degrees, the line is called the height. You need to calculate the height to determine the area.
So the triangle's height will divide the triangles into 2 smaller right triangles.
For the left right triangle, 2.5 will be hypotenuse
=> 2.5^2 = (height)^2 + (base1)^2
=> (height)^2 = 6.25 - (base1)^2
For the right right triangle, 4 will be hypotenuse
=> 4^2 = (height)^2 + (base2)^2
=> (height)^2 = 16 - (base2)^2
So
6.25 - (base1)^2 = 16 - (base2)^2
We have base1 + base2 = 5.8 => base1 = 5.8 - base2
Substitute
6.25 - (5.8 - base2)^2 = 16 - (base2)^2
6.25 - (33.64 - 11.6base2 + base2^2 = 16 - base2^2
base2^2 - base2^2 + 11.6base2 = 16 + 33.6 - 6.25
11.6base2 = 43.35
base2 = 43.35/11.6 = 3.74
since (height)^2 = 16 - (base2)^2
(height)^2 = 16 - (3.74)^2
height^2 = 2.0124
height = 1.42
so area = 1/2hb = 1/2(1.4)(5.8) = 4.06 cm^2

Answer:
85.54 cm
Step-by-step explanation:
To find the height of the scale model, we need to use the scale ratio given: 3 : 74. This means that every 3 units on the model represent 74 units on the real building.
First, we need to determine the ratio of the heights. Let x be the height of the scale model. Then:
3 / 74 = x / 21
Solving for x, we get:
x = 21 * 3 / 74
x = 0.8554 m
To convert this to centimeters, we multiply by 100:
x = 85.54 cm
Therefore, the height of the scale model is 85.54 cm to 2 decimal places.
