Answer:
1. The slope of the graph is 3/1 or 3
2. The slope of the graph is 3/4
3. The slope of the points is 2
4. The slope of the points is Undefined
5. The slope of the graph is 1
6. The slope of the points is -1/4
Step-by-step explanation:
To find the slope of the graph you use rise over run
To find the slope of the points you use y2-y1 over x2-x1
Hope this is very helpful!!
Answer:
1. -1/3
2. 3/4
3. 2
4. -9/0
5. 1
6. -6/4
Step-by-step explanation:
1. To find this numbers slope you have to go over and up (or down depending on where the line is going) You go over once and down three times to the next dot. This is why it is negative, because you go down
2. Same as number one you go over (Run) and up (Rise) . You go over 3 times and up 4. This makes it positive, since you are going up.
3. Stick to this formula (y2-y1)
(x2-x1)
-4-8
0-6 =-12/-6 =2
4. Same as 3
1-8
5-5 = -9/0
5. Go over 1 and up 1 this will equal 1/1 which is just 1.
6.
-2-4
-6-2 =-6/-8
This can be simplified down to -3/-4

The random variable X has mean 12 and standard deviation 3. The random variable W is defined as W = 7+2X. What are the mean and standard deviation of W?
A. The mean is 24, and the standard deviation is 6.
B. The mean is 24, and the standard deviation is 13.
C. The mean is 31, and the standard deviation is 3.
D. The mean is 31, and the standard deviation is 6.
E. The mean is 31, and the standard deviation is 13.
Answer: D. The mean is 31, and the standard deviation is 6.
Step-by-step explanation:
Given the data :
X = mean = 12 ; Standard deviation = 3
W = 7 + 2x
Variance of W = 2x
Variance = Standard deviation²
(2x)² = 4x²
Variance
Standard deviation of X = 3
Variance (W) = 4*3² = 4 * 9 = 36
Variance (W) = 36
Standard deviation = sqrt(variance)
Standard deviation = sqrt(36) = 6
Mean ; of x = 12
Mean(W) = 7 + 2(12)
Mean = 7 + 24
Mean = 31

Rita is a nurse her regular rate is $14.62 per hour. She is paid double-time (two times the hourly rate) for holidays. During one week she worked 36 regular hours plus 8 holiday hours.
The amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be $760.24.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Rita is a nurse her regular rate is $14.62 per hour. She is paid double-time (two times the hourly rate) for holidays.
Then the amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be
⇒ $14.62 x 36 + $14.62 x 2 x 8
⇒ $526.32 + $233.92
⇒ $760.24

Find x
27 degrees and 32 degrees will give brainlist
Answer:
x = 121°
Step-by-step explanation:
If you add up all the angles of a triangle, you get 180°.
So you must add up all the angles.
[tex]27+32+x=180\\\\59+x=180[/tex]
Next you subtract 59 on both sides.
[tex]x=121[/tex]
x should be 121°.
If you would like to check your answer, you can add up 27, 32, and 121. If it all equals to 180, then your answer is correct.

In the balance scale/equation analogy, what should you write in the blank on the right side of the equation in order to balance the scale for the following equation? 2(x + 1) = 2x + ______
(x + 1)
4
x
2
Answer:
Option D: 2 is the correct answer.
Step-by-step explanation:
Given equation is:
2(x + 1) = 2x + ______
For balancing the equation, the variables and constants must be same on both sides of the equation.
Simplifying 2(x+1) gives us 2x+2
As 2x is already there, we will add 2 with it in the equation.
Hence,
Option D: 2 is the correct answer.
