What does the line x= 2 look like?

Answers

Answer 1
Answer: X = 2 means for whatever y value you select the x value will be 2. So if you graph a couple of coordinates it becomes quickly evident that x = 2 is a vertical line that crosses the x axis at 2.
Answer 2
Answer: x = 2

This would show a vertical line crossing the x axis at 2. 

Since y = 0, there is no y intercept, which means it does not cross the y axis.

Write the sum using summation notation, assuming the suggested pattern continues. -10 - 2 + 6 + 14 + ... + 110

Answers

This is the sum of the arithmetic sequence:
 10 - 2 + 6 + 14 + ... + 110
where:  a 1 = - 10, d = 8
a n = 110
a n = a 1 + ( n - 1 ) * d
110 = - 10 + ( n - 1 ) * 8
110 = - 10 + 8 n - 8
110 + 10 + 8 = 8 n
128 = 8 n
n = 128 : 8
n = 16
∑ n = n/2 * ( a 1 + a n ) 
∑ 16 = 16/2 * ( -10 + 110 ) = 8 * 100 = 800
Answer:
The sum is 800.

If each quadrilateral below is a rectangle find the missing measure in #3

Answers

You can solve this exercise as below (View the figure attached):

 1.Divide the figure in four equals parts. Now we have 4 rectangles with the same dimensions.
 2.Choose the rectangle that has the angle given in the problem, which we will call "α" (α=59°). 
 3. We must remember that the sum of the internal angles of a triangle is 180°. We have α=59° and the right angle, so we can find the other one, which we will call "β1":
 β1=180°-90°-59° β1=31°
 4. As we can see in the figure, "α" is alternate interior with α1 (α=α1=59°) and β1 is alternate interior with m∠11 (β1=m∠11=31°).
 5. The others rectangles have the same dimensions of the rectangle we chose, so they have the same angles too.
 We can notice in the figure that m∠7+m∠8+m∠9+m∠10= 360°

 The answer is:
 m∠1=59°
 m∠2=31°
 m∠3=59°
 m∠4=31°
 m∠5=31°
 m∠6=59°
 m∠7=118°
 m∠8=62°
 m∠9=62°
 m∠10=118°
 m∠11=31°

The table gives the probability distribution of the annual rate of return on the stock of MNP Company, Inc.

The expected value of the rate of return is ______%.

Answers

Answer: The expected value of the rate of return is 23.5%.

Step-by-step explanation:

Since we have given that

Annual Return                   Probability

15%                                       0.2

20%                                      0.4

30%                                      0.3

35%                                      0.1

We need to find the expected value of the rate of return:

As we know the formula for "Expected value ": E(x)=\sum xp(x)

So, it becomes,

E(X)=15* 0.2+20* 0.4+30* 0.3+35* 0.1=23.5\%

Hence, the expected value of the rate of return is 23.5%.

Calculation:
15%*0.2 + 20%*0.4 + 30%*0.3 + 35%*0.1 = 23.5%

Answer:
The expected value of the rate of return is 23.5%

Answers

If you would like to know the solution to the system of equations, you can do this using the following steps:

y = –5x + 3
y = 1
_______________
1 = –5x + 3 
5x = 3 - 1
5x = 2    /5
x = 2/5 = 0.4

(x, y) = (0.4, 1)

The correct result would be (0.4, 1).
