Answer:

C. ∠ZXY and D. YX

Step-by-step explanation:

C. ∠ZXY

because the middle letter is always the angle or the turning point of an angle and also it is in order based on the diagram. The angle won't change even if you look at it on a different point of view or if the diagram was flipped.

D. YX

because the line YX is a true statement because XY or YX is on the same line that goes on and on. You can tell because there's arrows on the end of the line.

Answer:

22.4

Step-by-step explanation:

a^2 + b^2 c^2

20^2 + b^2 = 30^2

400 + b^2 = 900

b^2 = 500

b = 22.4

Answer:

30⁰ , 60⁰ , 90⁰

Step-by-step explanation:

Let the angles x , 2x , 3x

By angle sum property:

x + 2x + 3x = 180⁰

6x = 180⁰

x = 30⁰

Angles are : 30⁰ , 60⁰ , 90⁰

Let one angle be x, the second 2x and the third 3x.

x + 2x + 3x = 180 degrees (angle sum property of a triangle)

6x = 180 degrees

x = 180/6

x = 30 degrees

So one angle is 30°, the second is 60°, and the third is 90°.

Answer:

table b

Step-by-step explanation:

table b is the answer

In an incidence geometry with the additional axiom that every line has exactly three points lying on it, the minimum number of points required is 4.

This is because a line must have at least two-points to exist, and if it has only two points, it is not possible to have another point lying on it (since every line must have exactly three points).

Hence, there must be at least 4-points to create two lines such that each line contains exactly three points.

Also, with 4 points, it is possible to create 6 lines such that each line contains exactly 3 points, forming a configuration known as the Fano-plane, which is the smallest example of an incidence geometry that satisfies the given axiom.

The probability that a randomly selected label produced by the company will contain a defective compact disk is 0.034.

In this, it should be noted that there are 3 possible cases in the chosen disc can be from any of the manufacturing companies, so the total probability will be the sum of probabilities of getting a faulty disc from companies 1-3.

The probability from company 1 will be;

= 0.03*0.36

The probability from company 2 will be:

= 0.04*0.52

The probability from company 3 will be:

= 0.02*0.12

The total probability will now be:= (0.36*0.03)+(0.04*0.52)+(0.02*0.12)

= 0.0108 + 0.0208 + 0.0024

Answer:

container A

Step-by-step explanation:

In Container A, we can plot the points (0,60) adn (2, 35)

The slope is :

\(m_A = \frac{y_2-y_1}{x_2-x_1} \\\\= \frac{35-60}{2-0} \\\\= \frac{-25}{2}\\ \\m_A = -12.5\\\)

For container B, the slope is:

\(m_B = \frac{y_2-y_1}{x_2-x_1} \\\\= \frac{32-54}{3-1} \\\\= \frac{-22}{2}\\ \\m_B = -11\\\)

The negative sign of the slope indicates the direction of the slope

\(|m_A| = 12.5\\\\|m_B| = 11\)

12.5 > 11

The slope of container A is steeper than container B

Therefore, the water is draining out of container A at a faster rate than container B

To determine the number of times the spinner landed on green, we need to calculate the relative frequency of green and subtract it from 1 since the sum of relative frequencies for all possible outcomes should equal 1.

Let's denote the number of times the spinner landed on green as "x." We know that the relative frequency of red is 0.18 and the relative frequency of blue is 0.62. The relative frequency of green can be calculated as:

Relative frequency of green = 1 - (Relative frequency of red + Relative frequency of blue)

Relative frequency of green = 1 - (0.18 + 0.62) Relative frequency of green = 1 - 0.80 Relative frequency of green = 0.20

Since relative frequency is a proportion, we can calculate the number of times the spinner landed on green by multiplying the relative frequency by the total number of spins:

Number of times spinner landed on green = Relative frequency of green * Total number of spins

Number of times spinner landed on green = 0.20 * 350 Number of times spinner landed on green = 70

Therefore, the spinner landed on green 70 times.

The circulation γ about the rectangular closed curve defined by (x, y) = (1, 1), (3, 1), (3, 2), and (1, 2) is given by γ = 2b. This result is independent of the shape of the curve C and depends only on the velocity field v. This means that if we change the curve C while keeping the velocity field v fixed, the value of the circulation γ will remain the same.

We can evaluate the circulation γ about the rectangular closed curve defined by (x, y) = (1, 1), (3, 1), (3, 2), and (1, 2) by using Stokes’ Theorem. The circulation γ is given by:γ=∮Cv⋅dlwhere C is the closed curve and dl is an infinitesimal element of the curve.We can use Stokes’ Theorem to evaluate the circulation γ as follows:∮Cv⋅dl=∬S(∇×v)⋅dS,where S is any surface whose boundary is C. In this case, we can choose the surface S to be the rectangular surface defined by the points (1, 1, 0), (3, 1, 0), (3, 2, 0), and (1, 2, 0). Note that this surface lies in the xy-plane, and that its boundary is C. Therefore, we have:∮Cv⋅dl=∬S(∇×v)⋅dS=∬S(0, 0, b)⋅dS=bdS,where dS is an infinitesimal element of area on S. Since S is a rectangle with sides of length 2 and 1, we have:dS=dx dy=2 dy.Integrating over S, we get:γ=b∬S dS=b(2)(1)=2b.

From the above calculations, we can conclude that the circulation γ about the rectangular closed curve defined by (x, y) = (1, 1), (3, 1), (3, 2), and (1, 2) is given by γ = 2b. This result is independent of the shape of the curve C and depends only on the velocity field v. This means that if we change the curve C while keeping the velocity field v fixed, the value of the circulation γ will remain the same.

Answer:

Step-by-step explanation:

n + 1 = 4(n - 8)

n + 1 = 4n - 32      [Multiply 4 times (n-8)]

1 = 3n - 32           [Subtract 1n from both sides]

33 = 3n               [Add 32 to both sides]

3n = 33

CHECK:

Does n + 1 = 4(n - 8) when n = 11?

n + 1 = 4(n - 8)

11 + 1 = 4(11 - 8)

11 + 1 = 4(3)

Answer:

Step-by-step explanation:

The width of the rectangle is given by ...

  W = A/L

  W = (20 cm²)/(8 cm) = 2.5 cm

__

The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...

  W = (24 cm²)/(10 cm) = 2.4 cm

The percentage change in size is ...

  ((2.4 cm)/(2.5 cm) -1) × 100% = -4%

The width of the rectangle decreased less than 5%. Noah is correct.

Answer:

The two numbers are 8 and -2

Step-by-step explanation:

a=b+10

2(a+b)=12

you then substitute the first equation's value for a into the second equation.

2(b+10+b)=12

2(2b+10)=12

4b+20=12

b+5=3

b=-2

Then you substitute this value for b back into the first equation.

a=b+10

a=-2+10

a=8

Answer:

The median is 33.5

Step-by-step explanation:

In order to solve for a median it would either be the middle or it would be the average of the middle if there are even amount of numbers. First you would put them in order. 12 17 28 31 36 54 55 and 71. This would mean the the middle number would be 31 and 36. Since you can't have two medians you would find the average of the two so add 31 and 36 which would be equal to 67 then divide by 2 which would equal to 33.5.

The median of numbers 17, 12, 54, 36, 71, 28, 31, 55 is 33.5.

The median of a set of numbers is the middle value when the numbers are arranged in ascending or descending order.

To find the median of the given numbers, we first need to arrange them in ascending order:

12 17 28 31 36 54 55 71

Since there are an even number of numbers (8), the median will be the average of the two middle values, which are 31 and 36.

To find the average, we add the two numbers and divide by 2:

(31 + 36) / 2 = 67 / 2 = 33.5

Therefore, the median of the given numbers is 33.5.
