Option C, 36/3 square units, is equivalent to this answer, so that is the correct choice
What is a formula of area of triangle?
To calculate the area of a triangle, use the formula area = 1/2 * base * height.
To find the area of triangle ABC, we can use the formula:
Area = (1/2) * base * height
where the base and height are the dimensions of the triangle that form a right angle.
In this case, we don't have the dimensions of the triangle that form a right angle, but we know that the triangle has two angles that are 60 degrees each. This tells us that the triangle is an equilateral triangle, and all three sides are equal.
Let's call the length of each side "s". Then, we can use the formula for the area of an equilateral triangle:
[tex]Area = (\sqrt(3)/4) * s^2[/tex]
Plugging in the given value of 12 for s, we get:
[tex]Area = (\sqrt{(3)/4) * 12^2}\\\\ Area \ = (\sqrt{(3)/4) * 144} \\\\Area = 36\sqrt{(3)}[/tex]
Therefore, the area of triangle ABC is [tex]36\sqrt(3)[/tex] square units.
Option C, 36/3 square units, is equivalent to this answer, so that is the correct choice.

a hospital director is told that 55% of the treated patients are insured. the director wants to test the claim that the percentage of insured patients is less than the expected percentage. a sample of 230 patients found that 115 were insured. determine the p-value of the test statistic. round your answer to four decimal places.
The p-value of the test statistic is 0.0401, which is less than the commonly used significance level of 0.05.
In statistical analysis, hypothesis testing is an essential method used to make inferences about population parameters using sample data. In this case, a hospital director wants to test a claim that the percentage of insured patients is less than the expected percentage.
The alternative hypothesis is that the percentage of insured patients is less than the expected percentage. To test this hypothesis, the director will use a one-tailed z-test for proportions. The test statistic is calculated as:
z = (p - P) / √(P(1-P) / n)
where p is the sample proportion, P is the expected proportion under the null hypothesis, and n is the sample size.
In this case, the sample proportion is 115/230 = 0.5, and the expected proportion is not specified. However, since the null hypothesis is that the percentage of insured patients is equal to the expected percentage, we can use the observed percentage of 55% as a reasonable estimate of the expected percentage. Thus, P = 0.55.
Plugging in these values, we get:
z = (0.5 - 0.55) / √(0.55 * 0.45 / 230) = -1.74
p-value = -1.74/0.069 = 0.0401
Trough this one we have identified that the test statistic's p-value is 0.0401, indicating that it is below the widely accepted significance level of 0.05.
The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed one, assuming the null hypothesis is true.

5. A typical car salesman receives 25% of the profit made from selling a car as commission. A salesperson has earned $4,300 in commission this month. How much profit did the dealership make on the cars that he sold? (1) $107,500 (3) $10,750 (2) $17,200 (4) $1,075
Answer: (2) $17,200
Step-by-step explanation:
We know the commission = 4,300. So we need to find a number (Let's x) times 25% (equal to 0.25) equal to 4,300
Put all that into an equation: x times 0.25 = 0.25x
0.25x=4,300
Now, all we need to do is solve for x.
Divide both sides by 0.25 to get 17200
Use substitution to solve the system. +3x5y = 7 y = +2x4
Answer: To solve the system of equations using substitution, we'll start by rearranging one of the equations so that one of the variables can be expressed in terms of the other. In this case, we'll rearrange the second equation to find y in terms of x.
y = 2x + 4
Next, we'll substitute this expression for y into the first equation:
+3x + 5(2x + 4) = 7
Expanding the right-hand side:
+3x + 10x + 20 = 7
Combining like terms:
13x + 20 = 7
Subtracting 20 from both sides:
13x = -13
Dividing both sides by 13:
x = -1
Finally, we'll use the expression we found for y in terms of x to find the corresponding value of y:
y = 2x + 4
y = 2(-1) + 4
y = -2 + 4
y = 2
So the solution to the system is (x, y) = (-1, 2).

Jordan bought a $300,000 house, paying 10% down, and getting a 30 year loan with 3% interest for the remaining amount.
How much is the loan amount going to be?
What will her monthly payments be?
How much interest will she pay over the life of the loan?
Answer:
The down payment that Jordan made on the house was $300,000 x 10% = $30,000. So, he financed $300,000 - $30,000 = $270,000.
where
M = monthly payment
P = loan amount ($270,000)
r = monthly interest rate (3% / 12 months = 0.003)
n = number of payments (30 years x 12 months/year = 360)
This comes out to a monthly payment of approximately $1,173.38.
To simplify
The loan amount is- $270,000
Her monthly payment will be- $1,173.38
The amount of interest she will pay is- $8,100

Find a function rule for the line that passes through the origin (0,0) and the point ( -6 - 12,).
The function rule for the line that passes through the origin and (-6,-12) is y = 2x.
In mathematics, a function is a rule that assigns to each element in a set a unique output value.
To find a function rule for the line that passes through the origin (0,0) and the point (-6,-12), we first need to determine the slope of the line. The slope of a line represents the rate of change between the x and y coordinates. We can find the slope using the formula:
slope = (y₂ - y₁)/(x₂ - x₁)
where (x₁, y₁) represents the coordinates of the first point, and (x₂, y₂) represents the coordinates of the second point.
Using the given points, we can substitute in the values:
slope = (-12 - 0)/(-6 - 0)
slope = -12/-6
slope = 2
Now that we have the slope, we can use the point-slope form of a linear equation to find the function rule:
y - y₁ = m(x - x₁)
where m is the slope, and (x₁, y₁) represents the coordinates of a point on the line.
Substituting in the values we have so far, we get:
y - 0 = 2(x - 0)
y = 2x

twenty five people, consisting of women and men are lined up in a random order. find the probability that the ninth woman to appear is in position 17. that is, find the probability there are women in positions thru and a woman in position 17
The probability that the ninth woman to appear is in position 17 is about 5.59%
We can approach this problem by using the binomial probability distribution. Let X be the number of women among the first 16 people in the line. Then X follows a binomial distribution with parameters n = 16 and p, the probability that any given person among the first 16 is a woman. We want to find the probability that X = 8, since this means that the ninth woman to appear is in position 17.
The probability of any given person being a woman is not specified in the problem, but we can assume that it is 0.5 for simplicity. Therefore, p = 0.5, and we can use the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where (n choose k) is the binomial coefficient, which gives the number of ways to choose k items from a set of n items. In this case, it gives the number of ways to choose k women from the first 16 people in the line.
Using this formula with n = 16 and k = 8, we get:
P(X = 8) = (16 choose 8) * 0.5^8 * 0.5^8
= 12870 * 0.00390625
= 50.27
This means that the probability of exactly 8 women appearing among the first 16 people in the line is about 50.27%.
Given that there are 8 women among the first 16 people, the probability that the ninth woman appears in position 17 is 1/9, since there are 9 possible positions for the ninth woman to appear, and they are all equally likely.
Therefore, the overall probability that the ninth woman to appear is in position 17 is:
P(X = 8) * (1/9) = 50.27% * (1/9) = 5.59%

Which transformation maps △UVW to △EFG?
Option D (x, y)→ (-2x, 2y) is the transformation that maps triangle UVW to triangle EFG.
What do you mean by Transformation?In mathematics, a transformation refers to a process of changing the position, size, or orientation of a geometric shape. It is a fundamental concept in geometry, algebra, and other branches of mathematics that studies the properties of objects and their relationship with space.
Transformations can be classified into two main types: rigid and non-rigid transformations. Rigid transformations preserve the size and shape of the object while changing its position and orientation. Common examples of rigid transformations are translations, rotations, and reflections. Non-rigid transformations, on the other hand, change the size and shape of the object as well as its position and orientation.
Transformations are used in various areas of mathematics and science, such as computer graphics, physics, and engineering. They are also important in real-world applications, such as in designing and modeling objects, analyzing data, and solving practical problems.
The transformation involves a reflection across the y-axis (multiplication by -1 on the x-coordinate) and a dilation by a factor of 2 in the y-direction (multiplication by 2 on the y-coordinate).
Applying this transformation to the coordinates of triangle UVW:
(0, -2) -> (0, -4)
(2, 0) -> (-4, 0)
(-2, 2) -> (4, 4)
These transformed coordinates match the coordinates of triangle EFG, so option D is the correct answer.

The theater sells two types of tickets: adult tickets for $13 and child tickets for $3. Last night, the theater sold a total of 220 tickets for a total of $1820. How many adult tickets did the theater sell last night? Show your work here Enter your answer
The required adult tickets and 104 child tickets, which gives a total revenue of $1820.
What is equation of variable?An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable, then, is a symbol denoting a number whose value is unknown. In this case, x + 5 = 10. "X" in this case is a variable.
According to question:Let x be the number of adult tickets sold and y be the number of child tickets sold.
We know that the total number of tickets sold is 220:
x + y = 220
We also know that the total revenue from ticket sales is $1820:
13x + 3y = 1820
We can use the first equation to solve for y in terms of x:
y = 220 - x
Substituting this into the second equation, we get:
13x + 3(220 - x) = 1820
Simplifying this equation:
10x + 660 = 1820
10x = 1160
x = 116
Therefore, the theater sold 116 adult tickets last night.
To check, we can substitute x = 116 into the equation for y:
y = 220 - x = 220 - 116 = 104
So, the theater sold 116 adult tickets and 104 child tickets, which gives a total revenue of $1820.

Pls, answer! Lots of points! Question down below!
The polynomial (x-a)(x-b)(x-c)....(x-z) has a coefficient of -351 for the x²⁵ term. Since there are 26 variables, the sum of all coefficients is 2²⁵, or 33554432.
The polynomial (x-a)(x-b)(x-c)....(x-z) can be written as
x²⁶ - (a+b+c+...+z)x²⁶ + (sum of products of pairs)x²⁴ - ... - abc...xyz
The coefficient of x²⁵ is the negative sum of the constants, which is -(a+b+c+...+z). Since there are 26 variables in total, the sum of the constants is just the sum of the first 26 letters of the alphabet, which is
(a+b+c+...+z) = 1 + 2 + 3 + ... + 26 = 351
So the coefficient of x²⁵ is -351.
To find the sum of all the coefficients, we can simply evaluate the polynomial when x = 1. At x = 1, each term in the polynomial is just the product of some combination of (1-a), (1-b), (1-c), ..., and (1-z). Since each variable is a letter from the alphabet, each term is either 0 or 1, depending on whether the corresponding letter is equal to 1 or not.
The sum of all the coefficients is therefore just the number of terms in the polynomial that are equal to 1.
Since there are 26 variables, there are 2²⁶ possible combinations of (1-a), (1-b), (1-c), ..., and (1-z), and exactly half of them are equal to 1 (since each variable is either 0 or 1 with equal probability). Therefore, the sum of all the coefficients is
2²⁵ = 33554432
So the sum of the coefficients of the polynomial (x-a)(x-b)(x-c)....(x-z) is 33554432.

Answer:
Ac = 0.833334.
Step-by-step explanation:
SINCE THE QUESTION IS PYTHAGORAS THEOREM.
THE FORMULA IS
[tex] tan = \frac{ |bc| }{ac} [/tex]
From the question tan = 18°
bc = 15
ac= ?
making ac = x
therefore
[tex] tan = \frac{ |bc| }{ |ac| } \\ tan 18 = \frac{15}{x} \\ tan18(x) = x \times \frac{15}{x} \\ tan18x = 15 \\ = \frac{tan18x}{18} = \frac{15}{18} \\ x = 0.8333334[/tex]
therefore x = 0.8333334.
a person in a lighthouse 22m above sea level sights a buoy in the water. if the angle of depression to the buoy is 25o, how far from the base of the lighthouse is the buoy?
If the angle of depression to the buoy is 250, then the buoy is approximately 47.2 meters from the base of the lighthouse.
What is angle of depression ?
The angle of depression is the angle between a horizontal line of sight and the line of sight from an observer to a point or object that is lower than the observer. It is commonly used in trigonometry and geometry problems that involve the height or depth of an object relative to an observer or the ground.
We can start by drawing a diagram to visualize the situation.
In the diagram, A represents the location of the lighthouse, B represents the location of the buoy, and x represents the distance from the base of the lighthouse to the buoy that we want to find.
Since the angle of depression from the lighthouse to the buoy is 25 degrees, we know that angle ABx is also 25 degrees. We also know that the height of the lighthouse above sea level is 22 meters.
We can use the tangent function to find the value of x:
tan(25°) = opposite / adjacent
tan(25°) = 22 / x
Solving for x, we get:
x = 22 / tan(25°)
x ≈ 47.2 meters
Therefore, the buoy is approximately 47.2 meters from the base of the lighthouse.
