Answer: x= 24 and y= 73

Step-by-step explanation:

we know

The opposite interior angles are equal and

The angles on the same side of the transversal are supplementary, that means they add up to 180 degrees.
the sum of the interior angles of a parallelogram is 360 degrees.

So 107 + y = 180

180 - 107 = 73

Y = 73

y is equal to its opposite angle so

X can be found by 73 = 3x + 1

Subtract 1 from both sides

73 - 1 = 3x +1 -1

Simplify

72 = 3x

Divide both sides by 3 to solve for x

72/3 = 3/3x

x=24

Check your work by adding the 4 angles together to equal 360

107 + 107 + 73 + 73 = 360

360 = 360

They equal so your solution is correct

The equation for p is p + 6 = 14, which means that the number of pieces left is equal to the difference between the total number of pieces (14) and the number of pieces served (6).

Ron's mother bakes a pizza and divides it into 14 pieces. After serving 6 pieces to Ron and his friends, she has a certain number of pieces left. To determine this number, we can use the equation p + 6 = 14. This equation states that the number of pieces left (p) is equal to the difference between the total number of pieces (14) and the number of pieces served (6). Therefore, the equation for p is p + 6 = 14. By solving this equation, we can determine that the number of pieces left is 8. This means that Ron's mother has 8 pieces left after serving 6 pieces to Ron and his friends.

Using the circumference formula the number of full revolutions the wheels need to make to travel 220 feet is obtained as 35.

What is circumference?

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.

The distance traveled by the car in one full revolution of the wheel is equal to the circumference of the wheel.

The circumference of a circle is given by the formula -

C = 2πr

where C is the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Since the diameter of the wheel is 2 feet, the radius is half of that, or 1 foot.

Therefore, the circumference of the wheel is -

C = 2π(1 foot) = 2π feet

To find how many full revolutions the wheel needs to make to travel 220 feet, we can divide the distance traveled by the circumference of the wheel -

Number of revolutions = distance traveled / circumference of the wheel

Number of revolutions = 220 feet / (2π feet) ≈ 35.03

Therefore, the wheels need to make 35 full revolutions to travel 220 feet.

What is an inverse equation?

To find the inverse of the equation y = log(1/4)[tex]x^{5}[/tex], we can follow these steps:

Step 1: Interchange the x and y variables to obtain x = log(1/4)[tex]y^{5}[/tex].

Step 2: Solve for y in terms of x. To do this, we need to isolate the y term on one side of the equation. We can start by taking both sides of the equation to the power of 1/5:

[tex]x^{1/5}[/tex] = log(1/4)y

y = [tex](1/4)^{(1/log(x^(1/5)))}[/tex]

Step 3: Simplify the expression. Recall that [tex]a^b^{c}[/tex], so we can rewrite the exponent in the denominator as log([tex]x^{1/5}[/tex]) = (1/5)log(x). Substituting this into the expression for y, we get:

What is rectangle?

A rectangle is a two-dimensional geometric shape with four straight sides and four right angles (90 degrees). It is a type of quadrilateral, which means it has four sides. The opposite sides of a rectangle are equal in length, and the adjacent sides are perpendicular to each other.

The formula for calculating the area of a rectangle is A = l x w, where "A" is the area, "l" is the length, and "w" is the width. The perimeter of a rectangle can be calculated by adding the lengths of all four sides, which is given by the formula P = 2(l + w).

Rectangles are commonly found in many aspects of everyday life, such as in buildings, furniture, electronic devices, and books. They can be used in architecture and engineering for creating stable and functional structures. In mathematics, rectangles are often used in geometry and algebraic expressions, as well as in statisticalanalysis and graphing.

Here we have a rectangle with length 16m and breadth 13 m.

Now, area of the rectangle is length × breath = 13×16 = 208 m².

And here we also have two square parts with side 4 m .

So, area of the square is side × side = 4×4 = 16 m².

Now, numbers of square are 2.

So, total area of two square is (2×16) = 32 m².

If we will subtract the total area of two square from area of the rectangle then we will get the area of shaded region .

So, area of the shaded region [tex] = 208 - 32 = 176 \: {m}^{2} [/tex]

Therefore, area of the shaded region is 176 m² .

what is a circle?

A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center. It can also be defined as the set of points that are a fixed distance (called the radius) away from the center point. The distance around the circle is called its circumference, and the distance across the circle passing through the center is called its diameter.

Since quadrilateral WXYZ is inscribed in a circle, we know that opposite angles add up to 180 degrees. Therefore:

m∠Y + m∠W = 180 degrees ...(1)

m∠Z + m∠X = 180 degrees ...(2)

We are given that m∠W = 55 degrees and m∠X = 117 degrees, so we can substitute those values into equations (1) and (2):

m∠Y + 55 = 180 ...(1)

m∠Z + 117 = 180 ...(2)

Solving for m∠Y and m∠Z, we get:

m∠Y = 125 degrees

m∠Z = 63 degrees

GCD (119, 378) = 7 and x = 25 and y = -6 is the value by using Euclidean alogorithm.

What does Euclidean algorithm mean?

By dividing the larger by the smaller, the smaller by the remainder, the first remainder by the second remainder, and so on, until an exact division is achieved, the greatest common divisor is the exact divisor. Euclid's algorithm is also known as.

by Euclidean division algorithm,

378 = 3 × 119 +21

119 = 5 × 21 + 14

21 = 1 × 14 + 7

14 = 2 × 7 + 0

Therefore 7 is GCD of 119 and 378.

so, GCD(119 , 378) = 119x + 378y = 7

now 7 = 119x + 378y

⇒7 = 7 × 13x + 7 × 54y

⇒1 = 13x + 54y

⇒13 × 25 + 54 × (-6) = 13x + 54y

The probability of selecting a blue or green ball on the first draw is 2/3 or approximately 0.67.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur. If an event has a probability of 0.5, it means that the event is equally likely to occur or not occur. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Probability is an important concept in mathematics, statistics, and many other fields, as it allows us to make predictions and decisions based on the likelihood of certain outcomes.

According to the question:
The total number of balls in the bag is:

6 blue balls + 5 yellow balls + 4 green balls = 15 balls

The probability of selecting a blue or green ball on the first draw can be found by dividing the number of blue and green balls by the total number of balls:

P(blue or green) = (number of blue balls + number of green balls) / (total number of balls)

P(blue or green) = (6 + 4) / 15

P(blue or green) = 10 / 15

P(blue or green) = 2/3

Therefore, the probability of selecting a blue or green ball on the first draw is 2/3 or approximately 0.67.

The confidence level is the probability that a confidence interval will contain the true population parameter in repeated sampling.

Confidence level is a statistical measure used to indicate the level of certainty or reliability in a statistical inference or estimate. In other words, it represents the success rate of the method used to construct a confidence interval. For example, a 95% confidence level indicates that if we were to repeat the same experiment many times and calculate the confidence interval for each trial, then we would expect 95% of these intervals to contain the true value.

The confidence level is typically chosen by the researcher based on the level of certainty they want to achieve. A higher confidence level corresponds to a wider confidence interval, which increases the likelihood of containing the true value, but reduces the precision of the estimate.

It is important to note that the confidence level does not guarantee that a particular confidence interval contains the true value, but rather it indicates the long-run success rate of the method used to construct the interval. Therefore, it is crucial to understand the underlying assumptions and limitations of the statistical method used to construct the confidence interval.

We can use substitution to solve this system of equations. We can solve the first equation for y and get:

y = (2x + 12)/3

We can then substitute this expression for y into the second equation:

(2x + 12)/3 + 3x = -7

Multiplying both sides of this equation by 3 to eliminate the denominator, we get:

2x + 12 + 9x = -21

Simplifying this equation gives:

11x = -33

Dividing both sides by 11, we get:

x = -3

We can then substitute this value of x back into either of the two original equations to find y. Using the first equation, we get:

3y = 2(-3) + 12

3y = 6

y = 2

Therefore, the solution to the system of equations is x = -3 and y = 2.

To check the solution, we substitute these values back into both equations:

3y = 2x + 12 3(2) = 2(-3) + 12 6 = 6

This equation is true, so the solution (x = -3, y = 2) checks out.

The "loading" of the die makes P(1)=112, P(6)=312, and the following four outcomes equally likely. A roll with an even number larger than two has a 50% probability of occurring.

The probability of rolling an even number is 1/2 since there are three even numbers (2, 4, 6) and six possible outcomes in total.

The probability of rolling a number greater than two is 5/6 since there are five outcomes (3, 4, 5, 6) greater than two and six possible outcomes in total.

To find the probability that the number rolled is both even and greater than two, we need to find the probability of rolling a 4 or a 6 since these are even numbers that are greater than two.

The probability of rolling a 4 is P(4) = 1/12 + 1/6 = 1/4 since the die is loaded to favour a 6 over the other numbers, but all other outcomes are equally likely.

The probability of rolling a 6 is P(6) = 3/12 = 1/4 since the probability of rolling a 6 is given as 3/12.

Therefore, the probability of rolling an even number that is greater than two is:

P(even and greater than two) = P(4 or 6) = P(4) + P(6) = 1/4 + 1/4 = 1/2.

So the probability of rolling an even number that is greater than two is 1/2.
