The probability that the student selected is 5/8.

According to the question,

We have the following information:

A class consists of 30 women and 18 men.

Now, total students in the class = Number of women + number of men

Total students = 30+18

Total students = 48

Now, the probability that the student is a woman:

Probability of an event = Number of women/total number of students

30/48

(More to know: probability of an event can not be greater than 1.)

Now, converting this into the simplest form by dividing both the numerator and denominator by 6:

5/8

Hence, the probability that the student selected is 5/8.

For the given angles , the measure of the missing angles are as follow:

a. m ∠POQ = 36° , m ∠POR = 62°

b. m ∠RST = 40°

As given in the question,

For the given angles , the measure of the missing angles are given as follow:

a. Q is in the interior of angle POR ,

Measure of angle POR = 2x -2

Measure of angle POQ = x + 4

Measure of QOR = 26°

From the given relation of the angles we have,

m ∠POQ + m ∠QOR = m ∠POR

⇒ x + 4 + 26° = 2x -2

⇒2x -x = (2+ 4+ 26)°

⇒ x= 32°

m ∠POQ = x + 4

               = 32° + 4°

               = 36°

The horizontal line passing through the point (2, -6) is y = -6 and the vertical line passing through the point (2, -6) is x = 2

We need to write equations for the horizontal and vertical lines passing through the point (2, -6)

For a vertical line the value of x will never change. This will be true for any value of y.

So, the equation for a vertical line passing through this point is:

x = 2

Similarly, for a horizontal line the value of y will never change. This is true for any value of x.

So, the equation for a horizontal line passing through this point is:

y = -6

so I believe the question is

[tex]\frac{1}{4}[/tex]X - [tex]\frac{1}{3}[/tex]Y=1

and we want to know if that is linear, and what the standard form for the equation would be

let's move a few things around using our algebra skillz

[tex]\frac{1}{4}[/tex]X-1 = [tex]\frac{1}{3}[/tex]Y

[tex]\frac{3}{4}[/tex]X-3 = Y

y = [tex]\frac{3}{4}[/tex]x-3  (in standard form  y=mx+b)

The step-by-step explanation is in the screenshot below!

Using the linear function equation that models the situation given, the amount of credit left after 24 minutes of calls is: $25.2.

One of the ways to write a linear function equation is to express it in slope-intercept form as y = mx + b, where the slope is represented as m and the y-intercept is represented as b.

From the information given, we can deduce the following:

y = credit card remaining in dollars

x = minutes

Slope (m) = -0.13

A point = (x, y) = (32, 24.16)

Substitute m = -0.13, x = 32, and y = 24.16 into y = mx + b to find the value of b:

24.16 = -0.13(32) + b

24.16 = -4.16 + b

24.16 + 4.16 = b

28.32 = b

b = 28.32

Write the equation of the linear function by substituting b = 28.32 and m = -0.13 into y = mx + b:

y = -0.13x + 28.32

To find how much credit there was after 24 minutes of calls, substitute x = 24 into y = -0.13x + 28.32:

y = -0.13(24) + 28.32

y = 25.2

The term wy^2 out front multiplies with each term inside the parenthesis (because of the distributive rule).

Let's multiply the outer term with the first term inside the parenthesis to get the following:

wy^2 times 8y^3 = 8wy^5

Compare 8wy^5 with 40y^5, and we see the coefficients 8w and 40 match up. Therefore, 8w = 40 solves to w = 5

Compound interest is when an amount receives interest on top of it each time interest is paid on the original amount. The principal (original) sum and the interest that has already accrued over the course of previous periods are used to calculate compound interest.

here,

Caroline invested $80,000 in an account paying an interest rate of 8 1/8% compounded daily for 10 years,

A=P(1+r/n)^n/t

Step-by-step explanation:

The composition of the functions, when evaluated in x = 4, is:

g( f(4)) =  39

Here we have two functions, one is a linear function:

g(x) = 3.25*x + 6

And the other is f(x), which is defined on a table.

We want to find the composition:

g( f(4)) = 3.25*f(4) + 6

Then we need to find the value of f(4), on the table we have the pair:

x   f(x)

4    12

Which means that:

f(4) = 12

Replacing that we get:

g( f(4)) = 3.25*f(4) + 6

g( f(4)) = 3.25*12 + 6 = 39

m+ 3 = x (-12b+9)

x =   (m+3) / ( -12b+9)       0r     (m+3) / (9-12b)

The slope of the line that passes through the points (-1, 6) and (14, 3) is - 1 / 5.

We know that the slope of a line is given by the formula,

m = (y₂ - y₁) / (x₂ - x₁)

where (x₂, y₂) and (x₁, y₁) are the coordinates of any point on the line of slope.

We are given the following points;

(-1, 6) and (14, 3)

substitute the given value in the slope formula, we will get;

m = (3 - 6) / (14 - (- 1))

m = - 3 / 14 + 1

m = - 3 / 15

m = - 1 / 5

So, the slope is - 1 / 5.

The measure of  the angle AEG = 92°

Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal. The opening and shutting of a lunchbox, solving a Rubik's cube, and never-ending parallel railway tracks are a few everyday examples of corresponding angles. These are formed in the matching corners or corresponding corners with the transversal.

∠CFH + ∠EFC = 180( angles on a straight line)

making ∠EFC subject and substituting ∠CFH = 2x + 20, we have

∠EFC = 180 - ( 2x + 20)

∠EFC = 180 - 2x -20

∠EFC = 160 - 2x

but ∠EFC = ∠BEF ( alternate angles are equal)

substituting their values

160 - 2x = 3x - 10

collect like terms

-2x - 3x = -10 - 160

-5x = -170

x = -170/-5

x = 34

Also ∠EFC = ∠AEG = 160 -2x ( corresponding angles are equal)

∠AEG = 160 -2X, but x = 34

∠AEG = 160 - 2(34)

∠AEG =160 - 68 = 92°

The reduced or lowest form of 15 / 40 is 3 / 8. The given statement is true.

First, let us understand about the reducing a fraction:

To express a fraction in the lowest terms, divide the numerator and denominator by the greatest common factor of the numerator and denominator.

We are given:

15 / 40 = 3 / 8

Let the LHS; 15 / 40

We need to write the following fraction in the lowest terms:

15 / 40

To write 15 / 40 in the lowest terms, we divide the numerator and the denominator by the greatest common factor of 15 and 40.

Since the factors of 15 are 1, 2, 3, 5, and 15 and the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40, the greatest common factor of 15 and 40 will be 5.

So we will divide the numerator and the denominator of 15 / 40 by 5.

15 ÷ 5 = 3

40 ÷ 5 = 8

So, the reduced form of 15 / 40 is 3 / 8 which is 15 / 40 = 3 / 8.

Thus, the reduced or lowest form of 15 / 40 is 3 / 8. The given statement is true.

The statement that best describes how to determine if the plane clears the tower is;

Use the Pythagoras Theorem where the distance to the tower is a leg of the right triangle and the distance in the air is the hypotenuse. Find the other leg. Convert to feet to compare to the tower height

Given,

The length the plane will travel before lifting = 1500 yards

The distance further the plane will travel after lifting off the ground = 603 yards

The horizontal distance from the point of lifting off the ground to control tower = 600 yards

The horizontal distance from the point of liftoff to the control tower, the height of the control tower, and the distance of the plane's path after takeoff create a right triangle with the following sides:

The distance of the path of the plane after lifting off the ground = The hypotenuse side of the triangle

The horizontal distance from the point of lifting off the ground to control tower and the height of the control tower = The two legs of the right triangle

Let h stand for the height of the control tower, x for the horizontal distance from the plane's liftoff point to the control tower, and R for the length of the plane's route after liftoff, and we obtain;

h = √(R² - x²)

We have;

R = 603 yards

x = 600 yards

∴ h = √(R² - x²) = h = √(603² - 600²) = 60.07 yards

The height of the control tower, h = 60.07 yards

1 yard = 3 feet

∴ 60.07 yards = 3 × 60.07 feet ≈ 180.22 feet

Therefore, given that the height of the control tower = 198 feet, the plane at the height of approximately 180.22 feet clears the tower.

x = √(27/11) is the local minima of the function g(x) = x¹¹ - 3x⁹ +2

Given, a function g(x) = x¹¹ - 3x⁹ +2

we have to find the local minima using the second derivative test.

first we differentiate the function,

g(x) = x¹¹ - 3x⁹ +2

g'(x) = 11x^10 - 27x^8

Now, putting g'(x) = 0

11x^10 - 27x^8 = 0

x^8(11x² - 27) = 0

Now, x = 0 or x = √(27/11)

First, we need to solve this for n.

if we divide all the inequality by n, we will get:

-3 < 7 - 20/n < 3

Now we can subtract 7 in all the parts to get:
