The area of the triangle is 25061.6 cm²

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

The area of a triangle is expressed as;

A = 1/2bh where b is the base a d h is the height. This formula only works for right angled triangle.

Another formula for area of triangle is 1/2 absinC

a = 180cm

b = 280cm

C = 84°

A = 1/2 × 180 × 280 × sin84

A = 50123.9/2

A = 25061.6 cm²

Therefore the area of triangle OPQ is 25061.6 cm².

The value of x is 40 degree.

We have,

Far Arc = 130 degree

Near Arc = 50 degree

According to "Angle-Arc Theorem." It states that the angle formed by the intersection of two tangents, two secants, or one tangent and one secant outside a circle is equal to half the difference of the intercepted arcs.

In other words, The angle formed outside of the circle is always equal to the the far arc minus the near arc divided by 2.

Using Angle = (Far Arc - Near Arc) /2

So, x= (130- 50)/2

x = 80/2

x= 40

Thus, the value of x is 40 degree.

The median and the range for the data-set are given as follows:

The median of a data-set is the middle value of a data-set, the value of which 50% of the measures are less than and 50% of the measures are greater than. Hence, the median also represents the 50th percentile of a data-set.

The ordered data-set is given as follows:

3, 6, 12, 15, 17, 19, 21.

The middle value is of 15, hence it represents the median of the data-set.

The range of a data-set is defined as the difference between the largest and the smallest value in the data-set, hence:

21 - 3 = 18.

The coordinates of the hole of the rational function are (-3, -3).

Here we have the following rational function:

[tex]f(x) = \frac{x^2 + 3x}{x + 3}[/tex]

The hole is when the denominator becomes zero, that is at x = -3

Now, we can rewrite the numerator as:

x² + 3x = x*(x + 3)

Then we can rewrite the function as:

[tex]f(x) = \frac{x^2 + 3x}{x + 3} = \frac{x*(x + 3)}{x + 3} = x[/tex]

Evaluating that in x = -3 we get f(x) = -3, then the coordinates of the hole aer (-3, -3).

Answer: For Area A, 60

For Area B, 16

For Area C, 16

For the entire shape, 92

Step-by-step explanation:

If you look at the top of the entire shape, it says the width is 10 cm, that means 10 cm's for the entire width and not just shape A.

If you look at shape B, it says the width is 4 cm, that means 4 out of those 10 cm's are for B and not A but we dont need the width of shape B, so we subtract that 4 bc it isnt necessary since its not in shape A

if you look at the left of shape A, it says 10 cm for the height, when finding area for a rectangle, always do width x height. We have both the width and the height so now we just multiply them, 10 x  6 = 60

Answer:

A = 60cm^2

Step-by-step explanation:

Given:

Length of figure: A = 10cm

Width of figure: B = 10 - 4 = 6cm

Figure A is rectangular in nature.

So, the Area of the figure: A = 1 x b = 10 x 6 = 60cm^2

To answer the given questions, let's use conditional probability based on the information provided:

a. To find the probability that the selected student does not get a scholarship, given that they cannot get a job within 2 months after graduation, we can use Bayes' theorem. Let's denote the events as follows:

A: Not getting a scholarship

B: Not getting a job within 2 months after graduation

We want to find P(A|B), which is the probability of not getting a scholarship given that the student cannot get a job within 2 months. According to the given information, 25% of students who cannot get a job within 2 months get at least one university scholarship.

Using Bayes' theorem:

P(A|B) = (P(B|A) * P(A)) / P(B)

P(B|A) is the probability of not getting a job within 2 months given that the student does not get a scholarship. Since this information is not provided, we cannot determine this probability.

b. To find the probability that the selected student gets no university scholarship, we can use the law of total probability. Let's denote the events as follows:

A: Not getting a scholarship

B: Getting a job within 2 months after graduation

C: Not getting a job within 2 months after graduation

We want to find P(A), the probability of not getting a university scholarship. According to the given information, 60% of students get a job within 2 months after graduation, and among those students, 70% get at least one university scholarship. For students who cannot get a job within 2 months, 25% get at least one university scholarship.

Using the law of total probability:

P(A) = P(A|B) * P(B) + P(A|C) * P(C)

We don't have the values for P(A|B) or P(B) and P(A|C) or P(C), so we cannot calculate the exact probability of not getting a university scholarship.

Therefore, without additional information or values for conditional probabilities, we cannot provide specific numerical answers to these questions.

Answer:

s(x) = 0.23x + 400

Step-by-step explanation:

Let x = cost of merchandise sold

We start by finding the slope which is the percent of commission Alysse receives.

Let's start with doing 607 - 515. This is because we are subtracting the commissions, which also can be y2 - y1. Then, we do 900-500=400 (x2-x1). This is how to find the slope of the function. [tex]\frac{y2-y1}{x2-x1}=\frac{92}{400} =0.23[/tex], 0.23 being the slope.

s(x) = b+0.23x, now substitute values making the money received as s(x).

515 = b+0.23(500)

515=b+115

-115   -115

400 = b

607 = 400+0.23(900)

607 = 400 + 207

607 = 607

So, s(x) = 0.23x + 400

The caluclated values are:

N = 500:

SEM = 9 * √[(500 - 48) / (500 - 1)] / √(48)

= 1.24 (rounded to 2 decimals)

N = 5000:

SEM = 9 * √t[(5000 - 48) / (5000 - 1)] / √(48)

= 1.30 (rounded to 2 decimals)

N = 50000:

SEM = 9 * √[(50000 - 48) / (50000 - 1)] / √(48)

Step-by-step explanation:

using the sine ratio in the right triangle

sin P = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{12}{13}[/tex] , then

∠ P = [tex]sin^{-1}[/tex] ( [tex]\frac{12}{13}[/tex] ) ≈ 67° ( to the nearest degree )

Let [tex]x[/tex] be one of the numbers. Then the other one is [tex]10-x[/tex].

Therefore, the sum of their cubes is:

[tex]x^3+(10-x)^3=x^3+1000-300x+30x^2-x^3=30x^2-300x+1000[/tex]

Now we need to find the minimum value of the resulting function.

[tex](30x^2-300x+1000)'=60x-300[/tex]

[tex]60x-300=0\\60x=300\\x=5[/tex]

The derivative is negative to the left of [tex]5[/tex] and positive to the right of it, therefore, at [tex]5[/tex] there exists the minimum.

[tex]5^3+(10-5)^3=125+125=250[/tex]

Therefore, the minimum value is 250.

When A plug is removed from a trough to drain the water, The appropriate form of the expression is 10(x - 1)² - 3. Option D

The appropriate form of the expression that would reveal the time, in minutes, when the trough is empty is: 10(x - 1)² - 3.

This expression represents the volume of the trough after the plug is removed, with x representing the time in minutes. When the volume of the trough is equal to zero, it means the trough is empty.

Therefore, setting the expression equal to zero and solving for x will give us the time when the trough is empty.

The correct statement would be: An ice cream would need more than 9 votes from the first-place line in the preference schedule.

To determine the number of votes an ice cream would need to accumulate in order to be the majority winner, we should analyze the preference schedule provided.

Looking at the preference schedule, we can see that there are four ice cream flavors:

Chocolate (C), vanilla (V), strawberry (S), and pistachio (P).

Each row represents the rankings given by Janice's friends.

To be the majority winner, an ice cream flavor would need to accumulate more votes than any other flavor.

In this case, we can determine the highest number of votes an ice cream flavor can receive by considering the first-place line in the preference schedule.

From the first-place line, we can see that the maximum number of votes any flavor has received is 9.

Therefore, an ice cream flavor would need more than 9 votes from the first-place line to be the majority winner.
