The best description of the shape and center of the dotplot is that distribution of math classes is unimodal symmetric with a center around 4 classes. The Option C is correct.

A dot plot shows the frequency of each value in a dataset. To identify if the distribution of classes is unimodal symmetric, we will check if the dots are roughly evenly distributed around a central line which is the 4 classes.

This indicates the distribution is symmetric. We have a single peak in the data. If there is only one prominent cluster of dots, then, the distribution is unimodal. So, the distribution of classes is unimodal symmetric on the dot plot.

The probability density function f(x) is (1/10)e^(-x/10) for x > 0 and 0 elsewhere, and P(X > 12) is approximately 0.3012.

(a) To find the probability density function, f(x), we need to differentiate the cumulative distribution function F(x) with respect to x.

Given F(x) = 1 - e^(-x/10) for x > 0 and 0 elsewhere, we have:

f(x) = dF(x)/dx

= d(1 - e^(-x/10))/dx for x > 0 f(x)

= (1/10)e^(-x/10) for x > 0 and 0 elsewhere.

(b) To find P(X > 12), we can use the complementary probability, which is 1 - P(X ≤ 12).

Using the cumulative distribution function

F(x): P(X > 12)

= 1 - F(12) = 1 - (1 - e^(-12/10))

= e^(-12/10) ≈ 0.3012.

So, the probability density function f(x) is (1/10)e^(-x/10) for x > 0 and 0 elsewhere, and P(X > 12) is approximately 0.3012.

The total distance of the race is 2/5 of a mile. And since Achille's speed is 13 mph, the time it took him to run the race is:

Time is approximately 4.62 minutes.

Let's call the total race distance "d". Then we know that:

Achille's distance = d

Turtle's distance = d - 2/5

Since Achille runs at a speed of 13 mph, we can calculate the time it took him to run the race as follows:

Time = d / 13

And for the turtle:

Time = (d - 2/5) / 1

Since both started at the same time, we set the two time equations equal to each other:

d / 13 = (d - 2/5) / 1

Solving for d, we find that:

d = 13 * (d - 2/5)

Expanding the right side of the equation:

d = 13d - 26/5

Solving for d, we find that:

12d = 26/5

d = 26 / (5 * 12) = 26 / 60 = 13 / 30 = 2/5

So, the total distance of the race is 2/5 of a mile. And since Achille's speed is 13 mph, the time it took him to run the race is:

Time = 2/5 / 13 = 2 / (5 * 13) = 2 / 65 hours = 2 / 65 * 60 minutes = approximately 4.62 minutes.

There is a 4/5 probability of catching a T-shirt that is not a size small.

Simply put, the probability is the likelihood that something will occur.

When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

So, there were 50 shirts thrown into the throng in total.

There were 10 little shirts thrown.

15 medium-sized shirts were hurled.

The quantity of extra-large and big shirts.

= Total shirts - ( 10 + 15)

= 50 - 25 = 25

So, a total of 25 shirts are scattered throughout the large/extra large shirts.

A number of shirts that are NOT SMALL size are now available.

= Total shirts - Shirts with small size = 50 - 10 = 40

Probability of getting a not small t-shirt = The total not small t-shirt/The total number of t-shirts

= 40/50

= 4/5

Therefore, there is a 4/5 probability of catching a T-shirt that is not a size small.

Answer:

vertex = (1, - 9 )

Step-by-step explanation:

The x- coordinate of the vertex is at the midpoint of the zeros.

Given

f(x) = (x - 4)(x + 2)

Find the zeros by letting f(x) = 0 , that is

(x - 4)(x + 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 4 = 0 ⇒ x = 4

Then

\(x_{vertex}\) = \(\frac{-2+4}{2}\) = \(\frac{2}{2}\) = 1

Substitute x = 1 into f(x) for corresponding y- coordinate

f(1) = (1 - 4)(1 + 2) = (- 3)(3) = - 9

Answer:

The equation in slope-intercept form is:

\(y=\frac{1}{3}x+3\)

So the second option is the correct one.

Step-by-step explanation:

Step 1: Identify the gradient

The perpendicular line's equation is given as:

\(y=-3x+4\)

This equation is in the form of:

\(y=mx+b\)

Upon comparing the \(x\) components of both equations, we get\(-3x=mx\\\text{Remove the}~ x~ \text{from both sides:}\\-3=m\\m=-3\)

So, the gradient of this 'reference' equation is -3.

The equation we need to find is perpendicular to this 'reference' equation.

So, its gradient should be the negative reciprocal of the gradient of the 'reference' equation.

The negative reciprocal of -3 is:

\(-\frac{1}{(-3)}\\=\frac{1}{3}\)

So, the gradient of our equation is \(\frac{1}{3}\).

Step 2: Create the equation:

The equation crosses the x-axis at -9, which means its y-coordinate is 0 (at x-axis, y=0) ,so its coordinate is \((-9,0)\).

The formula for an equation is:

\(y-y_{1}=m(x-x_{1})\)

The coordinate \((x_{1},y_{1})\) is \((-9,0)\), and the gradient (\(m\)) is \(\frac{1}{3}\).

Substitute the values into the equation:

\(y-y_{1}=m(x-x_{1})\\y-0=\frac{1}{3}(x-(-9))\\\\\text{Simplify}\\y=\frac{1}{3}(x+9)\)

\(\text{Simplify further}\\y=\frac{1}{3}x+3\)

Since, the slope-intercept form is:

\(y=mx+b\)

We already have our equation in the slope-intercept form.

The function $f(x, y) = 11x - 5y$ has a global maximum of $105$ at $(0, 6)$ and a global minimum of $-54$ at $(0, -9)$, the first step is to find the critical points of the function.

The critical points of a function are the points where the gradient of the function is equal to the zero vector. The gradient of the function $f(x, y)$ is: ∇f(x, y) = (11, -5)

```

The gradient of the function is equal to the zero vector at $(0, 6)$ and $(0, -9)$. Therefore, these are the critical points of the function.

The next step is to evaluate the function at the critical points and at the boundary of the region. The boundary of the region is given by the inequalities $y \ge x - 9$, $y \ge -x - 9$, and $y \le 6$.

The function $f(x, y)$ takes on the value $105$ at $(0, 6)$, the value $-54$ at $(0, -9)$, and the value $-5x + 54$ on the boundary of the region.

Therefore, the global maximum of the function is $105$ and it occurs at $(0, 6)$. The global minimum of the function is $-54$ and it occurs at $(0, -9)$.

The first step is to find the critical points of the function. The critical points of a function are the points where the gradient of the function is equal to the zero vector. The gradient of the function $f(x, y)$ is: ∇f(x, y) = (11, -5)

The gradient of the function is equal to the zero vector at $(0, 6)$ and $(0, -9)$. Therefore, these are the critical points of the function.

The next step is to evaluate the function at the critical points and at the boundary of the region. The boundary of the region is given by the inequalities $y \ge x - 9$, $y \ge -x - 9$, and $y \le 6$.

We can evaluate the function at each of the critical points and at each of the points on the boundary of the region. The results are shown in the following table:

Point | Value of $f(x, y)$

The largest value in the table is $105$, which occurs at $(0, 6)$. The smallest value in the table is $-54$, which occurs at $(0, -9)$. Therefore, the global maximum of the function is $105$ and it occurs at $(0, 6)$. The global minimum of the function is $-54$ and it occurs at $(0, -9)$.

The probability that the second binary digit of a randomly generated 8-byte string is 1 is 1/256.

The probability that the second binary digit of a randomly generated 8-byte string is 1 can be determined by considering the number of favorable outcomes (strings where the second binary digit is 1) and dividing it by the total number of possible outcomes (all 8-byte strings).

Since each byte can take on 256 possible values (0 to 255), the total number of possible 8-byte strings is \((256)^8\).

Now, let's focus on the second binary digit. In a binary representation, the second digit can only be 0 or 1. If we fix the second digit as 1, we have 1 choice for that digit.

For the remaining 7 bytes, each byte can still take on 256 possible values.

Therefore, the number of favorable outcomes is 1 × \((256)^7\) (1 choice for the second digit and 256 choices for each of the remaining 7 bytes).

The probability is then calculated by dividing the number of favorable outcomes by the total number of possible outcomes:

Probability = (1 × \((256)^7\)) / (\((256)^8\)) = 1/256.

Hence, the probability that the second binary digit of a randomly generated 8-byte string is 1 is 1/256.

In response to the given question, we can state that we know that sum of all angles in a triangle is 180. m∠C = 4*11.67+43 = 89.68 = =90

A triangle is a polygon because it contains four or more parts. It features a simple rectangular shape. A triangle ABC is a rectangle with the edges A, B, and C. When the sides are not collinear, Euclidean geometry produces a single plane and cube. If a triangle contains three components and three angles, it is a polygon. The corners are the points where the three edges of a triangle meet. The sides of a triangle sum up to 180 degrees.

we know that sum of all angles in a triangle is 180.

2x - 12 + 4x + 43 + 9x - 26 = 180

15x  + 5 = 180

15x = 175

x = 11.67

Answer:

m∠C = 119°

Step-by-step explanation:

According to the Exterior Angle Theorem, the exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.

From inspection of the given triangle, the exterior angle is (9x - 26)° and the two non-adjacent interior angles are ∠B and ∠C.

Equate the sum of the two non-adjacent angles to the exterior angle and solve for x:

⇒ (2x - 12)° + (4x + 43)° = (9x - 26)°

⇒ 2x - 12 + 4x + 43 = 9x - 26

⇒ 6x + 31 = 9x - 26

⇒ 57 = 3x

⇒ x = 19

To calculate the measure of angle C, substitute the found value of x into the expression for the angle:

⇒ m∠C = (4x + 43)°

⇒ m∠C = (4(19) + 43)°

⇒ m∠C = (76 + 43)°

⇒ m∠C = 119°

The correct answer is D. f(x) = 11x - 4 and g(x) = (x + 4)/11

To determine which pair of functions are inverses of each other, we need to check if the composition of the functions results in the identity function, which is f(g(x)) = x and g(f(x)) = x.

Let's test each option:

Option A:

f(x) = x/2 + 15

g(x) = 12x - 15

f(g(x)) = (12x - 15)/2 + 15 = 6x - 7.5 + 15 = 6x + 7.5 ≠ x

g(f(x)) = 12(x/2 + 15) - 15 = 6x + 180 - 15 = 6x + 165 ≠ x

Option B:

f(x) = ∛3x

g(x) = (x/3)^3 = x^3/27

f(g(x)) = ∛3(x^3/27) = ∛(x^3/9) = x/∛9 ≠ x

g(f(x)) = (∛3x/3)^3 = (x/3)^3 = x^3/27 = x/27 ≠ x

Option C:

f(x) = 3/x - 10

g(x) = (x + 10)/3

f(g(x)) = 3/((x + 10)/3) - 10 = 9/(x + 10) - 10 = 9/(x + 10) - 10(x + 10)/(x + 10) = (9 - 10(x + 10))/(x + 10) ≠ x

g(f(x)) = (3/x - 10 + 10)/3 = 3/x ≠ x

Option D:

f(x) = 11x - 4

g(x) = (x + 4)/11

f(g(x)) = 11((x + 4)/11) - 4 = x + 4 - 4 = x ≠ x

g(f(x)) = ((11x - 4) + 4)/11 = 11x/11 = x

Based on the calculations, only Option D, where f(x) = 11x - 4 and g(x) = (x + 4)/11, satisfies the condition for being inverses of each other. Therefore, the correct answer is:

D. f(x) = 11x - 4 and g(x) = (x + 4)/11
