Therefore, the area of triangle XYZ is (1/2)bh = (1/2)(15)(15√3) = 225√3. Therefore, the area of triangle XYZ is 225√3.

Triangle is a three-sided polygon that has three angles and three sides. It is one of the basic shapes in geometry and is a very important concept in mathematics. It is also used in various fields, such as physics and engineering. Triangles can be classified into different types, such as right triangles, isosceles triangles, acute triangles, obtuse triangles, and equilateral triangles. Triangles are also used to form polygons, such as quadrilaterals, pentagons, and hexagons.

To find the area of triangle XYZ, we must first calculate the length of each side of triangle XYZ. The length of each side can be determined by multiplying the length of each side of triangle ABC by five.

Since all three sides of triangle ABC are equal in length, then each side of triangle XYZ will be 5 times the length of triangle ABC. Therefore, the length of each side of triangle XYZ is 5 times the side length of triangle ABC, or 15.

The area of the triangle can be calculated using the Triangle Area formula, A = (1/2)bh, where b is the base of the triangle and h is the height of the triangle. Since we know the length of each side of triangle XYZ, we can use these values to calculate the base and height of the triangle. The base of the triangle is 15, and the height of the triangle is 15√3.

Therefore, the area of triangle XYZ is (1/2)bh = (1/2)(15)(15√3) = 225√3. Therefore, the area of triangle XYZ is 225√3.

Answer:

Step-by-step explanation:

There is a 2.28% chance that more than 250 books were borrowed in a week.

Probability can also be calculated using other methods, such as counting techniques and probability distributions. Probability distributions provide a way to model the behavior of random events and describe the likelihood of different outcomes occurring.

Probability has many applications in fields such as statistics, finance, engineering, and science. It is used to make predictions, analyze data, and make decisions based on uncertain information. Understanding probability is an important skill for many professions, as it allows individuals to make informed decisions and assess risk.

To solve this problem, we need to use the standard normal distribution and calculate the z-score.

First, we find the z-score:

z = (x - μ) / σ

z = (250 - 190) / 30

z = 2

We can then use a standard normal distribution table or calculator to find the probability of getting a z-score of 2 or higher.

Using a standard normal distribution table, we find that the probability of getting a z-score of 2 or higher is approximately 0.0228.

To convert this to a percentage, we multiply by 100:

0.0228 x 100 = 2.28%

Therefore, there is a 2.28% chance that more than 250 books were borrowed in a week.

A linear equation in the form p = mn + b that gives the price they can charge for n shirts is p = -0.003x + 22.

In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

At data point (1000, 19), a linear function in standard form for this line can be calculated by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 19 = (16 - 19)/(2000 - 1000)(x - 1,000)

y - 19 = -0.003(x - 1,000)

a. Variables:

D0 = Demand for nurses in 2000 = 2,000,000

S0 = Supply of nurses in 2000 = 1,890,000

D2020 = Projected demand for nurses in 2020 = 2,810,414

S2020 = Projected supply of nurses in 2020 = 2,001,998

Equations:

For 2000: D0 = S0

For 2020: D2020 = S2020

b. Using substitution, we can set the two equations equal to each other:

D0 = S0

2,000,000 = 1,890,000 + m(S0 - 1,890,000) (where m is the rate of increase in supply)

m = 0.063

Now we can use this value of m to find out during which year the supply of nurses was equal to the demand:

2,000,000 = 1,890,000 + 0.063(S - 1,890,000)

S = 2,013,008

Therefore, the supply of nurses was equal to the demand in the year 2013.

Solving for r:

V = (1/3)πr^2h

3V = πr^2h

r^2 = (3V)/(πh)

r = sqrt[(3V)/(πh)]

Given that V = 660cm^3, h = 14cm and π = 22/7:

r = sqrt[(3 × 660)/(22/7 × 14)] ≈ 7 cm

So the radius is approximately 7 cm.

To find the value of h:

V = (1/3)πr^2h

660 = (1/3)(22/7)(7^2)h

660 = (22/3)(49/7)h

660 = (22/3)(7)h

Therefore, when w = 1/2, the expression w + 1/2w + 2 evaluates to 17/4.

You must replace each variable with a number and carry out the arithmetic procedures to evaluate an algebraic expression. Variable x in the preceding example is equivalent to 6, as 6 + 6 = 12. We can substitute our variables with their values before evaluating the expression if we are aware of their values.

To evaluate the expression for w = 1/2, we substitute w = 1/2 into the expression:

w + 1/2w + 2

= 1/2 + 1/2(1/2) + 2 (substitute w = 1/2)

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The probability of getting a green pea can be estimated by dividing the number of green peas by the total number of peas:

probability of green pea = number of green peas / total number of peas

In this case, the number of green peas is 439 and the total number of peas is the sum of the green and yellow peas, which is:

total number of peas = number of green peas + number of yellow peas

= 439 + 30 = 469

Therefore, the probability of getting a green pea is:

probability of green pea = 439 / 469 ≈ 0.935 or 93.5%

So, the estimated probability of getting an offspring pea that is green is approximately 93.5%.

We can solve this equation using the quadratic formula, which states that for a quadratic equation of the form ax^2 + bx + c = 0, the solutions for x are given by:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = -10, and c = 18. Substituting these values into the quadratic formula, we get:

x = (-(-10) ± sqrt((-10)^2 - 4(1)(18))) / 2(1)

Simplifying the expression inside the square root, we get:

x = (10 ± sqrt(100 - 72)) / 2

x = (10 ± sqrt(28)) / 2

x = (10 ± 2sqrt(7)) / 2

Answer: The equation of a circle with center (a,b) and radius r is given by:

(x - a)^2 + (y - b)^2 = r^2

In this case, the center is (9,10) and the point on the circle is (7,4). To find the radius, we can use the distance formula between the center and the point on the circle:

r = sqrt((7 - 9)^2 + (4 - 10)^2) = sqrt((-2)^2 + (-6)^2) = sqrt(40)

So, the equation of the circle is:

(x - 9)^2 + (y - 10)^2 = 40

Alternatively, we can also expand the equation to get:

x^2 - 18x + 81 + y^2 - 20y + 100 = 40

Simplifying and rearranging, we get:

x^2 + y^2 - 18x - 20y + 41 = 0

The multiple of the unit fraction 3/8​ is 15/40.

What is fraction ?

A fraction is a number that represents a part of a whole. It is a way of representing a quantity that is not a whole number. Fractions are written with two numbers, one above the other and separated by a horizontal line. The number above the line is called the numerator, and the number below the line is called the denominator.

To find the multiple of a fraction, you simply multiply the numerator and the denominator by the same number. For example, to find the multiple of 3/8, you can multiply both the numerator and the denominator by 2:

3/8 * 2/2 = 6/16

So the multiple of 3/8 by 2 is 6/16.

Similarly, you can find the multiple of 3/8 by any other number by multiplying both the numerator and denominator by that number. For instance, if you want to find the multiple of 3/8 by 5, you can multiply both the numerator and the denominator by 5:

3/8 * 5/5 = 15/40

Therefore, the multiple of the unit fraction 3/8​ is 15/40.

The combined shapes of one or more simple polygons and circles make up the area of the composite shapes. We can add the areas of all the fundamental shapes together to determine the area of the composite shapes. Simply calculate the area of each individual form to obtain the area of composite shapes.

The compound figure's area can be calculated by breaking it up into smaller shapes and adding the areas of each one.

Then, divide the figure into two rectangles:

The first rectangle is 2 m by 9 m in size and has a surface area of 18 m².

The surface area of the second rectangle, which is 3 m by 7 m in size, is 21 m².

Next, we may determine the areas of the two triangles:

Due to its 2 m base and 2 m height, the first triangle has an area of 1/2 x 2 m x 2 m, = 2 m².

The second triangle has a base of 3 m and a height of 2 m, and its area is 1/2 x 3 m x 2 m = 3 m².

The two rectangles' overlap can then be subtracted:

The overlap is a rectangle that is 2 m by 3 m in size, or 6 m2, and measures 2 m by 3 m.

The total area of the compound figure is calculated by adding the areas of the two rectangles, the two triangles, and then deducting the overlap between the rectangles.

Total area is (18 m² + 21 m²) + (2 m² + 3 m²) - 6 m².

Total area: 41 m².
