Step-by-step explanation:

To solve this problem, we need to calculate the probability of the first student being a boy and the second student being a girl.

There are a total of 13 boys and 15 girls in the class, making a total of 28 students.

The probability of the first student being a boy is given by:

P(boy) = Number of boys / Total number of students = 13 / 28

After the first student is selected, there are now 27 students remaining (since one student has already been selected). Out of these 27 students, there are still 15 girls remaining.

The probability of the second student being a girl, given that the first student was a boy, is given by:

P(girl|boy) = Number of girls / Remaining number of students = 15 / 27

To find the probability of both events occurring (the first student being a boy and the second student being a girl), we multiply the individual probabilities:

P(boy and girl) = P(boy) * P(girl|boy) = (13/28) * (15/27)

Calculating this expression:

P(boy and girl) ≈ 0.2041

Therefore, the probability that the first student is a boy and the second student is a girl is approximately 0.2041 or 20.41%.

If h(x) = f(–x), this is saying that your graph will be reflected over the y-axis.  In other words, the x-values of every point on the graph of y=f(x) will be switched to the opposite sign.  The graph will be flipped over sideways.

For example, if (1,-4) is a point on y=f(x), then y=h(x) will have (–1,-4) on it.

If h(x) = –f(x), this is saying that your graph will be reflected over the x-axis.  In other words, the y-values of every point on the graph of y=f(x) will be switched to the opposite sign.  The graph will be flipped upside-down.

For example, if (1,–4) is a point on y=f(x), then y=h(x) will have (1,4) on it.

While you are given the equation for f(x) in each exercise, the function f(x) does not impact the transformation at all.  What is said above is true for all functions.

The ballroom dance couple can arrange their performance in 28 different ways by selecting 6 routines out of the 8 they have learned.

The idea of combinations can be used.

The number of ways to select k items from a set of n items is given by the formula for combinations:

C(n, k) = n! / (k! * (n - k)!)

In this case, n = 8 (the total number of routines they have learned) and k = 6 (the number of routines they will perform).

Using the formula, we can calculate:

C(8, 6) = 8! / (6! * (8 - 6)!)

= 8! / (6! * 2!)

The factorial function is represented in this case by the exclamation symbol (!).

The sum of all positive integers from 1 to n is the factorial of the number n.

Calculating the factorials involved:

8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40,320

6! = 6 * 5 * 4 * 3 * 2 * 1 = 720

2! = 2 * 1 = 2

Plugging in these values:

C(8, 6) = 40,320 / (720 * 2)

= 40,320 / 1,440

= 28

Therefore, the ballroom dance couple can arrange their performance in 28 different ways by selecting 6 routines out of the 8 they have learned.

Step-by-step explanation:

Where the graph crosses the x-axis will solve the equation

The center of the circumscribed circle is (1, 5).

We calculate the midpoint and slope of the line segment AB:

Midpoint of AB = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

Midpoint of AB = ((2 + 0) / 2, (8 + 8) / 2)

Midpoint of AB = (1, 8)

Slope of AB = (y₂ - y₁) / (x₂ - x₁)

= (8 - 8) / (0 - 2)

Slope= 0

We can notice that the equation of the perpendicular bisector of AB is x = 1.

We also find midpoint and slope of the line segment  BC

Midpoint of BC = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

= ((0 + 2) / 2, (8 + 2) / 2)

= (1, 5)

Slope of BC = (y₂ - y₁) / (x₂ - x₁)

= (2 - 8) / (2 - 0)

= -3

y - 5 = -3(x - 1)

y - 5 = -3x + 3

3x + y = 8

we have the equations of two perpendicular bisectors which are

x = 1 and 3x + y = 8.

We Substitute x = 1 into 3x + y = 8:

3(1) + y = 8

3 + y = 8

y = 5

To find the greatest common factor (GCF) of the polynomial [tex]-x^2 + 6x - 19,[/tex] we need to factorize the polynomial and identify the common factors among its terms.

First, let's examine the polynomial and see if we can factor it further:

It is important to note that the GCF represents the highest degree of common factors that can be factored out from all terms of a polynomial. In this particular case, the polynomial does not possess any common factors that can be factored out.

It's worth mentioning that this polynomial is already in its simplest form and cannot be factored further.

However, if the polynomial had common factors that could be factored out, such as common binomial factors or other mathematical patterns, the GCF would differ from 1.

Step-by-step explanation:

The equation of a parabola with a vertical axis of symmetry,

focus (h, k+p), and directrix x=h-p is given by:

[tex](x - h)^2 = 4p(y - k)[/tex]

In this case, the focus is (0, 1) and the directrix is x =3.

Comparing this to the general equation,

we have

h = 0, k = 1, and x = h - p = 3.

From x = h - p, we can solve for p:

3 = 0 - p

p = -3

Substituting the values of h, k, and p into the equation, we get:

[tex](x - 0)^2 = 4(-3)(y - 1)[/tex]

Simplifying further:

[tex]x^2 = -12(y - 1)[/tex]

[tex]x^2=-12y+1[/tex]

[tex]x^2+12y=1[/tex]

Therefore, the parabola equation is [tex]x^2+2y=1[/tex]

The expression -2(5 + 7x) + 5(x + 5) is equivalent to the expression -9x + 15. So, the answer is option B: 15 - 9x.

To simplify the expression -2(5 + 7x) + 5(x + 5), we can distribute the coefficients and simplify further.

Starting with the expression -2(5 + 7x):

-2(5 + 7x) = -2 × 5 - 2 × 7x

= -10 - 14x

= -14x - 10

Now let's simplify the expression 5(x + 5):

5(x + 5) = 5 × x + 5× 5

= 5x + 25

Finally, combining the two simplified expressions:

-14x - 10 + 5x + 25

Combining like terms:

(-14x + 5x) + (-10 + 25)

-9x + 15

Therefore, the expression -2(5 + 7x) + 5(x + 5) is equivalent to the expression -9x + 15.

Year 7: $893.00

The depreciation schedule using the Modified Accelerated Cost Recovery System (MACRS) is prepared as follows:

Given data:

Purchase cost of the metal-working lathe: $38,000

Business use percentage: 90%

Section 179 deduction: $18,000

Special depreciation allowance: 50%

Depreciable basis = Purchase cost - Section 179 deduction

Depreciable basis = $38,000 - $18,000 = $20,000

Special depreciation allowance = $20,000 * 50%

Special depreciation allowance  = $10,000

Adjusted depreciable basis = $20,000 - $10,000

Adjusted depreciable basis  = $10,000

The recovery period for a metal-working lathe is 7 years.

Using MACRS, the depreciation rates for a 7-year recovery period are as follows:

The Horizontal distance from the base of the skyscraper to the ship is approximately 403.81 feet.

We can use trigonometry and the concept of angles of depression. We can consider the height of the observation deck as the opposite side and the horizontal distance to the ship as the adjacent side of a right triangle.

Given that the angle of depression is 67 degrees and the height of the observation deck is 955 feet, we want to find the horizontal distance (adjacent side).

Using the trigonometric function tangent, we can set up the following equation:

tan(67°) = opposite/adjacent

tan(67°) = 955/adjacent

To find the value of the adjacent side (horizontal distance), we can rearrange the equation:

adjacent = 955/tan(67°)

Using a calculator, we can evaluate the tangent of 67 degrees:

tan(67°) ≈ 2.3693

Now we can substitute this value into the equation:

adjacent = 955/2.3693

adjacent ≈ 403.81

To discover the finest range of applications that may in shape in the truck, we want to calculate the volume of the truck and divide it by using the quantity of every cube-formed bundle.

The quantity of the truck is given with the aid of the method:

Volume = Length x Width x Height

Volume = 8 ft x 61 ft x 71 ft

Volume = 34,808 cubic toes

The volume of every cube-shaped bundle is given with the aid of the method:

Volume = Side [tex]Length^3[/tex]

Volume = 1 [tex]ft^3[/tex]

Number of packages = Volume of truck / Volume of each package

Number of packages = 34,808 ft^3 / 1 ft^3

Number of packages = 34,808

Thus, the greatest number of packages that can fit in the truck is 34,808.

Volume of the part of the truck being filled = Number of packages x Volume of each package

Volume of the part of the truck being filled = 34,808 x 1 ft^3
