Answer:
His gross pay would be reduced $174.66.
Step-by-step explanation:
Gross pay of Marquis = $816
His withholding are :
Federal tax = $92.00
Social security tax = 6.2% of $816
= 0.062 × 816
= $50.592
Medicare tax = 1.45% × 816
= 0.0145 × 816
= $11.832
State tax = 22% × 92
= 0.22 × 92
= $20.24
Total withholding = 92 + 50.59 + 11.83 + 20.24
= $174.66
His net pay = $816 - $174.66 = $641.34
His gross pay would be reduced $174.66

A field test for a new exam was given to randomly selected seniors. The exams were graded, and the sample mean and sample standard deviation were calculated. Based on the results, the exam creator claims that on the same exam, nine times out of ten, seniors will have an average score within 6% of 80%.
Is the confidence interval at 90%, 95%, or 99%? What is the margin of error? Calculate the confidence interval and explain what it means in terms of the situation.
Answer:
Margin of error: 6%; Confidence Interval Percentage: 90%; Confidence Interval: 74% and 86%
Step-by-step explanation:
Margin of error: 6% -- It's already given in the question.
Confidence interval is at 90%. 9/10=.90
The exam creator is saying that they are 90% confident that the seniors test scores will be between 74% and 86%.
0.8 - 0.06 = 0.74
0.8 + 0.06 = 0.86
The confidence interval is (0.74, 0.86)

Using the rule of thirds to evaluate the composition of a well-crafted painting, the eye should be attracted to A. one or more points of interest. B. the top of the painting. C. the lighter values in the painting. D. the midpoint of the composition.
Answer: A: one or more points of interest.
Step-by-step explanation:
The rule says that an image should be divided into 9 equal squares by two horizontal and two vertical lines and that the important objects of the image should be placed between the lines (in the centers of the squares) or in the intersections of the lines.
In this way, the eye is dragged to the different points that the artist wants the viewer to focus on the image, then the correct option is option A: one or more points of interest.
Find the circumference of the circle if the square has an area of 144 m2. Give your answer to the nearest tenth. Use 3.14 form
The circumference of the circle is found by first determining the side length of the square, then using that to calculate the diameter and radius of the circle. Using 3.14 as an approximation for pi, the circumference is calculated to be 37.7 meters when rounded to the nearest tenth.
To find the circumference of the circle when the square has an area of 144 m², we first determine the side length of the square using the formula for the area of a square, A = a², where A is the area and a is the side length.
A = 144m²
a = 12m
Since the area is 144 m², the side length of the square is "12 m (since 12 x 12 = 144).
Since the circle fits perfectly within the square, the diameter D of the circle is equal to the side length of the square. Therefore, D = 12 m. The radius r is half the diameter, so in this case, r = 6 m.
The formula for the circumference C of a circle is C = 2πr.
C = 2 x 3.14 x 6 m = 37.68 m
The circumference is 37.7 m.
solve.
5m + 7/2 = -2m + 5/2

If 7 units represent 98 liters find the value of 15 units
Final answer:
To find the value of 15 units when 7 units represent 98 liters, set up a proportion, cross multiply, and divide to find the value of 15 units, which is 210 liters.
Explanation:
To find the value of 15 units when 7 units represent 98 liters:
Set up a proportion: 7 units = 98 liters and determine the value of 15 units.Cross multiply to solve for the unknown value: 7 units * x liters = 15 units * 98 liters.Divide to find the value of 15 units: x = (15 * 98) / 7 = 210 liters. Consider a triangle where A=30 degrees, a=1.5cm and b=2cm
How many possible triangles have the above properties? Write either 0 or 1 or 2.
I don't understand this question at all. ...?
With the given conditions of angle A being 30 degrees, side a being 1.5 cm, and side b being 2 cm in a triangle, only one possible triangle satisfies these properties according to the Law of Sines.
Explanation:The question relates to determining the number of possible triangles given certain conditions. Specifically, it refers to a triangle with an angle A of 30 degrees, a side a of 1.5 cm opposite to A, and another side b of 2 cm. To decide the number of possible triangles that fit these criteria, we make use of the Law of Sines. This law states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.
In the given scenario, since side a (1.5 cm), opposite to angle A (30 degrees), is shorter than side b (2 cm), it is possible that two different triangles could exist, often referred to as the ambiguous case in the Law of Sines. However, the fact that side a is shorter than side b coupled with angle A being acute (30 degrees) leaves us with only one possible triangle. This is because the side opposite the smallest angle (A) cannot form a valid triangle if it's longer than the other given side. Therefore, there is just one solution to this problem.

If 100 envelopes cost 70 cents, how much would 250 cost?
To find out how much 250 envelopes would cost, set up a proportion using the given information that 100 envelopes cost 70 cents. Cross-multiply and solve for the unknown cost, which is $1.75.
Explanation:To find out how much 250 envelopes would cost, you can use the concept of proportions. Since 100 envelopes cost 70 cents, you can set up a proportion to find the cost of 250 envelopes: 100/70 = 250/x, where 'x' represents the unknown cost. Cross-multiplying, you get 100x = 70 * 250. Dividing both sides by 100, you find that x = 175.
Therefore, 250 envelopes would cost 175 cents.
In decimal form, 175 cents is equal to $1.75.

A 16-inch cheese pizza at Fine Dough Pizza costs $10.00 and each additional topping is $1.50. The same size pizza at Johnson's Pizza costs $8.00 and each additional topping is $2.00. After how many toppings do the pizzas cost the same? Which pizza costs more with additional toppings?
To find the number of toppings at which the pizzas cost the same, we can set the total cost expressions for both pizzas equal to each other and solve for 'x'. After 4 additional toppings, the pizzas will cost the same. With 5 additional toppings, Johnson's Pizza costs more.
Explanation:To find the point at which the pizzas cost the same, we need to determine the number of toppings that will make the total cost equal for both pizzas. Let's denote the number of additional toppings as 'x', and the cost of each additional topping at Fine Dough Pizza as $1.50, and at Johnson's Pizza as $2.00. The total cost for Fine Dough Pizza will be $10.00 + $1.50x, and the total cost for Johnson's Pizza will be $8.00 + $2.00x. To find the number of toppings at which the pizzas cost the same, we can set the two total cost expressions equal to each other and solve for 'x':
$10.00 + $1.50x = $8.00 + $2.00x
To solve the equation, we can subtract $1.50x from both sides:
$10.00 = $8.00 + $0.50x
Next, we subtract $8.00 from both sides:
$2.00 = $0.50x
To isolate 'x', we divide both sides by $0.50:
x = 4
Therefore, after 4 additional toppings, the pizzas will cost the same.
To determine which pizza costs more with additional toppings, we can compare the total cost expressions for both pizzas for a specific number of toppings. For example, let's consider 5 additional toppings:
Total cost at Fine Dough Pizza = $10.00 + $1.50(5) = $10.00 + $7.50 = $17.50
Total cost at Johnson's Pizza = $8.00 + $2.00(5) = $8.00 + $10.00 = $18.00
Therefore, with 5 additional toppings, Johnson's Pizza costs more.
