It is true that the areas of regions B and C added together equal the area of region A.

A region is an area of land that has a distinct physical or cultural identity. Regions are typically characterized by particular geographic features, such as mountains, rivers, or seas; by cultural attributes, such as language, religion, or government; or by economic activities, such as farming, mining, or industry.

Assume that A, B, and C will have diameters of a, b, and c, respectively.
Consequently, the semicircle's surface area is,
A = 1/2π(d/2)²
A = (π/8) d²
In a right-angled triangle, the square on the hypotenuse is equal to the particular sum of the squares of one two sides. With a right triangle,
a² = b² +c²   ----(1)
The areas for regions A, B, and  C will be  (π/8) a²,  (π/8) b², and  (π/8) c² accordingly.
Equation 1's (/8) multiplication yields,
(π/8) a² = (π/8) b² +(π/8) c²
The result is
Region A's area is equal to Region B's plus Region C's.

Complete Question:

It is true that the areas of regions B and C formed by the semi circles added together equal the area of region A.

What is semi circle?

In geometry, a semicircle can be defined as a half circle made by cutting the circle into two halves. It is formed when a line passes through the center of a circle and touches the two ends of the circle which is the diameter of the circle.

Let us assume that A, B, and C will have diameters of a, b, and c, respectively.

By the formula of semicircle's surface area,

A = 1/2π(d/2)² where d is the diameter of the semi circle.

A = (π/8) a² [ since diameter of semicircle A is a]

By Pythagoras theorem, In a right-angled triangle, the square on the hypotenuse is equal to the  sum of the squares of  two sides.

So here from the right angled triangle we get,

a² =b² +c²   ----(1)

The area for region A is  (π/8) a²

The area of  region B is (π/8) b²

and  the area of region C is (π/8) c²

Now, Area of region B + Area of region C

= (π/8) b² + (π/8) c²

= (π/8) ( b² +c² )

= (π/8) a² [ from equation (1)]

Hence , Region A's area is equal to Region B's plus Region C's area.

An inequality in mathematics is a link between two expressions or values that is not equal. As a result, inequality results from imbalance. An inequality in mathematics is a relationship between two values that are not equal. Equality and inequality are not the same thing. The not equal sign is often used to indicate that two values are not equal (). To contrast values, various disparities—no matter how small or large—are used. By changing the two sides until just the variables are left, many fundamental inequalities can be resolved. Yet, a variety of causes fuel inequality: On both sides, negative values are divided or added. Trade right and left.

To find the equation of a line passing through two given points, we can use the point-slope form of a linear equation:

[tex]y-ylm(x-x1) = \\m = (y^2 - y1)/(x^2 − x^1) \\m = (3-2)/(2-1) = 1\\ m = y-2=1\\(x-1) y-2=x-1\\y = x+1[/tex]

The minimum score required for the job offer found using normal distribution is 629

To find the minimum score required for the job offer, we have to use the standard normal distribution formula.

Where Z-score can be calculated as,

Z = (x - μ) / σ

Z-score is the number of standard deviations from the mean.

μ = Mean = 455

σ = Standard Deviation = 124

Substituting the values, we get, Z = (x - μ) / σ= (x - 455) / 124

Probability value = 1 - 0.08 = 0.92

The probability of getting scores in the top 8% is 0.92.

By using the standard normal distribution table, we can find the corresponding z-value, where the area under the curve to the right of that value is 0.92.

So, the corresponding Z-value is 1.44.

Z-value = 1.4 = (x - 455) / 124

We can solve the above equation for x (minimum score required for the job offer).

x = Z * σ + μ = 1.4 * 124 + 455 = 628.6 ≈ 629

Round off the answer to the nearest whole number, we get the minimum score required for the job offer is 629.

The probability of selling more than 5 properties in a week is 0.7494 (rounded to four decimal places).

The probability of selling more than five properties in a week would be calculated using the binomial distribution method. Binomial distribution is used to calculate the probability of an event happening, given a specific number of trials and assuming that each trial is independent of the others. In this case, we want to know the probability of selling more than five properties in a week.

The formula for the probability of selling more than five properties in a week is:
P(X > 5) = 1 - P(X ≤ 5)
Where P is the probability of selling any one property in a week, and X is the number of properties sold in a week.
Using the binomial probability formula, we can determine the probability of selling exactly k properties in one week:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where
n = 12 (total number of properties)
k = number of properties sold
p = 0.40 (probability of selling any one property in a week)
We can now calculate the probability of selling more than 5 properties in a week:

P(X > 5) = 1 - P(X ≤ 5)
P(X > 5) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5))
P(X > 5) = 1 - [(12 choose 0) * (0.40)^0 * (0.60)^(12-0) + (12 choose 1) * (0.40)^1 * (0.60)^(12-1) + (12 choose 2) * (0.40)^2 * (0.60)^(12-2) + (12 choose 3) * (0.40)^3 * (0.60)^(12-3) + (12 choose 4) * (0.40)^4 * (0.60)^(12-4) + (12 choose 5) * (0.40)^5 * (0.60)^(12-5)]
P(X > 5) = 1 - [0.000015 + 0.0003 + 0.003 + 0.018 + 0.068 + 0.161]
P(X > 5) = 1 - 0.250583

To solve a system of equations, you need to find the values of the variables that satisfy both equations simultaneously. There are different methods to solve systems of equations, including substitution, elimination, and graphing. Here's an example of using substitution:

Solve the system of equations:

2x + y = 5

x - y = 1

From the second equation, we get x = y + 1. Substitute this expression for x into the first equation:

2(y + 1) + y = 5

Simplifying and solving for y, we get:

3y + 2 = 5

3y = 3

y = 1

Then, substitute y = 1 into x = y + 1 to get:

x = 2

So the solution to the system of equations is x = 2 and y = 1.

To solve a system of inequalities, you need to find the values of the variables that satisfy both inequalities simultaneously. There are different methods to solve systems of inequalities, including graphing and substitution. Here's an example of using graphing:

Solve the system of inequalities:

x + y ≤ 3

x - y > 1

First, graph the boundary lines of each inequality. For the first inequality, the boundary line is x + y = 3, which is a line with intercepts (3, 0) and (0, 3). To decide which side of the line to shade, test a point that is not on the line, such as (0, 0):

0 + 0 ≤ 3, which is true

Therefore, shade the side of the line that contains the origin.

For the second inequality, the boundary line is x - y = 1, which is a line with intercepts (1, 0) and (0, -1). To decide which side of the line to shade, test a point that is not on the line, such as (0, 0):

0 - 0 > 1, which is false

Therefore, shade the side of the line that does not contain the origin.

The shaded region that satisfies both inequalities is the region that is below the line x + y = 3 and to the right of the line x - y = 1. This region is a triangle with vertices (1, 2), (2, 1), and (2, 2).

To find the number of degrees the minute hand turned from its first position to its second position, we need to find the difference between the two angles formed by the minute and hour hands.

In the first position, the minute hand forms a 46° angle with the hour hand. Since the hour hand is pointing at 10 and the minute hand is between 10 and 11, we know that the hour hand has moved 1/6th of the way from 10 to 11, or 30°. Therefore, the angle between the hour hand and the 12:00 position is 120° + 30° = 150°. So the minute hand is 46° away from 150°, or 104°.

In the second position, the minute hand forms an 84° angle with the hour hand. Since the hour hand is pointing at 10 and the minute hand is between 11 and 12, we know that the hour hand has moved 1/2 of the way from 10 to 11, or 150°. So the minute hand is 84° away from 150°, or 234°.

To find the number of degrees the minute hand turned, we subtract the two angles: 234° - 104° = 130°.

Therefore, the minute hand turned 130° from its first position to its second position.

The value of x, the missing side which is the hypotenuse, is approximately 24.85 units.

To solve this problem, we can use the trigonometric function of sine, since we know the opposite side and we want to find the hypotenuse.

The sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse:

sin(θ) = opposite/hypotenuse

In this case, θ is the angle 75 degrees, the opposite side is 24, and we want to find the hypotenuse x:

sin(75°) = 24/x

To solve for x, we can cross-multiply:

x * sin(75°) = 24

Then, we can divide both sides by sin(75°):

x = 24 / sin(75°)

Based on the measures of center, we can conclude that Wide Awake typically sells more coffee per hour compared to Perks A Lot.

Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data.

To determine which coffee shop typically sells the most amount of coffee per hour, we need to compare the measures of center for both sets of data. The two common measures of center are the mean and the median.

Calculating the mean and median for both sets of data, we get:

Perks A Lot:

Mean = (10+3.5+3+5+2.5+7+8+5.5+9.5+6+9+4.5)/12 = 5.75

Median = the average of the 6th and 7th numbers when the data is arranged in order: 3, 3.5, 5, 5.5, 6, 7, 8, 9, 9.5, 10

Wide Awake:

Mean = (2.5+10+4+18+4+3+6.5+15+6+5+2.5)/11 = 6

Median = the average of the 5th and 6th numbers when the data is arranged in order: 3, 4, 5, 6, 6.5, 10, 15, 18

Comparing the measures of center, we can see that Perks A Lot has a lower mean and a higher median compared to Wide Awake. This suggests that Perks A Lot sells less coffee on average, but has more consistent sales with less extreme values. On the other hand, Wide Awake has higher average sales, but with a wider range of values.

Therefore, based on the measures of center, we can conclude that Wide Awake typically sells more coffee per hour compared to Perks A Lot.

The approximate length of each of the walking paths that passes through the center of the park and connects opposite sides of the outer or circumference walkway is 21 meters.

Let r₁ and C₁  be the radius and the circumference of the inner circle.

Let r₁​ and C₂  be the radius and the circumference of the outer circle.

The width of the circular path is (r₂​ −r₁ ) m.

Given, C₂ −C₁ = 132 m

⇒2πr₂−2πr₁ = 132m

⇒2π(r₂ −r₁ ) = 132m

⇒r₂−r₁ = 66/22/7

​⇒r₂−r₁ = 21

Thus, width of the circular path is 21 m.

Answer:

u = 26.1°

Step-by-step explanation:

the 2 angles u and 44.1° combine to form the angle 70.2° , that is

u + 44.1° = 70.2° ( subtract 44.1° from both sides )

u = 26.1°
