The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:
Number: 0 1 2 3 4 5 6 7 8 11 12
Frequency: 5 16 20 14 3 5 4 4 2 1 1
The probability of an events, say E is the ratio of the number of favorable outcomes to the total number of outcomes.
[tex]P(E)=\frac{n(E)}{N}[/tex]
Compute the probabilities of 0 - 12 hurricanes each season as follows:
Number Frequency Probability
0 5 0.07
1 16 0.21
2 20 0.27
3 14 0.19
4 3 0.04
5 5 0.07
6 4 0.05
7 4 0.05
8 2 0.03
11 1 0.01
12 1 0.01

Step-by-step explanation:

The restriction that should be applied to the function [tex]y = tanx[/tex] for [tex]tan^{-1} (x)[/tex] to be defined is option (C) restrict the domain to [tex](-\frac{\pi }{2} ,\frac{\pi }{2} )[/tex] is the correct answer.
What is graph of a function?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The graph of a function f is the set of all points in the plane of the form (x, f(x)).
For the given situation,
The graph below shows the functions tan(x) and arctan(x) that is tan^-1(x)
In order to have an inverse function for trigonometry, we restrict the domain of each function, so that it is one to one.
A restricted domain gives an inverse function because the graph is one to one and able to pass the horizontal line test.
Thus by restricting the domain [tex](-\frac{\pi }{2} ,\frac{\pi }{2} )[/tex] we can obtain the function [tex]tan(x)[/tex] as [tex]tan^{-1} (x)[/tex].
Hence we can conclude that the restriction that should be applied to the function [tex]y = tanx[/tex] for [tex]tan^{-1} (x)[/tex] to be defined is option (C) restrict the domain to [tex](-\frac{\pi }{2} ,\frac{\pi }{2} )[/tex] is the correct answer.

Answer:
the inverse of a function takes the output of the actual function as the input and gives the input of the initial function as the output
here, we are given that when we input 23 in the inverse function of 'f', we get 3
this means that if we input 3 in the initial function, we will get 23 as the output
f(x) = x² - ax + 8
changing the input value to 3
f(3) = (3)² - 3a + 8
changing the output value to 23
23 = 9 - 3a + 8
3a = 17 - 23
3a = -6
a = -2

One endpoint of a line segment has coordinates represented by (x+4,1/2y). The midpoint of the line segment is (3,−2).
How are the coordinates of the other endpoint expressed in terms of x and y?
Answer:
[tex]\displaystyle \left(-x+2, -\frac{1}{2}y-4}\right)[/tex]
Step-by-step explanation:
We are given that one of the endpoints of the line segment is:
[tex]\displaystyle \left( x + 4, \frac{1}{2}y\right)[/tex]
And that the midpoint of the line segment is (3, -2).
And we want to find the other coordinates in terms of x and y.
We can consider using the midpoint formula:
[tex]\displaystyle M = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]
We are given that the midpoint is (3,-2). Substitute:
[tex]\displaystyle (3, -2) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]
We can solve for each coordinate independently.
x-coordinate:
We have:
[tex]\displaystyle 3=\frac{x_1+x_2}{2}[/tex]
One of the two endpoints is (x + 4, 1/2y). Hence, we can substitute x + 4 for x₁:
[tex]\displaystyle 3=\frac{(x+4)+x_2}{2}[/tex]
Solve for the second x-coordinate x₂:
[tex]\displaystyle \begin{aligned} 6 & = x+4 + x_2 \\ \\ x_2 + x & = 2 \\ \\ x_2 & = -x +2 \end{aligned}[/tex]
Hence, the x-coordinate of the second point is -x + 2.
y-coordinate:
We have:
[tex]\displaystyle -2=\frac{y_1+y_2}{2}[/tex]
We can substitute 1/2y for y₁. This yields:
[tex]\displaystyle -2=\frac{\dfrac{1}{2}y+y_2}{2}[/tex]
Solve for y₂:
[tex]\displaystyle \begin{aligned} -4 & = \frac{1}{2}y + y_2 \\ \\ y_2 & = -\frac{1}{2}y - 4\end{aligned}[/tex]
In conclusion, the other coordinate expressed in terms of x and y is:
[tex]\displaystyle \left(-x+2, -\frac{1}{2}y-4}\right)[/tex]

Step-by-step explanation:
Pat started reading at 1pm . He reads five pages in 15 minutes. If Pat reads until 2:45 pm, how many pages has he read?
Answer:
35 pages
Step-by-step explanation:
First count how many minutes have passed. Divide by 15, then multiply by 5 since 5 pages are read every 15 minutes.
Answer:
35 pages
Step-by-step explanation:
If Pat reads 5 pages in 15 minutes, then it means that for every 5 pages he reads, it will take him 15 minutes. So, his rate is 5/15, simplified to 1/3. For every 1 page he reads, it will take him 3 minutes. 1pm-2:45pm is 1 hour and 45 minutes, which is 105 minutes. Now we just have to divide it by 3, since he reads 1 page every 3 minutes. 105/3=35. He will read 35 pages.

Answer:
6. Ethan should shade the region marked B
7. No, point (0, 4) will not be included in the solution set
8. Point (0, -2) will not be included in the solution set
Step-by-step explanation:
Let us explain how to solve the question
The graph represents the equation 2x - 5y = 10
The inequality is 2x - 5y > 10
The sign of inequality is greater than without equal, that means the line represents it must be a dotted line because all the points on the line do not belong to the solution set of the inequality.
To find the area of the solution you must put y on a side and the other term on the other side
∵ 2x - 5y > 10
→ Add 5y to both sides to move y in the other side
∴ 2x - 5y + 5y > 10 + 5y
∴ 2x > 10 + 5y
→ Subtract 10 from both sides to move 10 to the other side
∵ 2x - 10 > 10 - 10 + 5y
∴ 2x - 10 > 5y
→ That means 5y < 2x - 10
∴ 5y < 2x - 10
6.
→ y < that means the area of the solutions is under the line
∴ The solutions of the inequality lie in area B
∴ Ethan should shade the region marked B
7.
∵ Point (0, 4) lies above the line in the region marked A
→ That means it does not lie in the area of the solutions
∴ Point (0, 4) will not be included in the solution set
8.
∵ Point (0, -2) lies on the line
∵ All the point on the line did not belong to the solution set as we
said before
∴ Point (0, -2) will not be included in the solution set
