Probability is defined as the <u>likelihood or the certainty</u> that an event is going to<u> occur or happen.</u>
The probability of randomly choosing a red and then a green marble is  .
.
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
<u>The probability of choosing a red marble</u> = Number of red marbles / Total number of marbles
= 5/20 
<u>In simplest fraction form</u> = 
We are told in the question that you keep the red marble you choose, So this means the <u>total number of marbles</u> left reduces to 19
<u>The probability of choosing a green marble is</u> =  Number of green marbles / New total number of marbles
= 3/19 
Therefore, <u><em>the probability of randomly choosing a red and then a green marble is </em></u>
P (Red) x P(Green)
= 1/4  x 3/19
=

Answer:
D. There is a nonlinear relationship between the speed and fuel efficiency.  
Step-by-step explanation:
A desirable residual plot should show a horizontal band with points randomly distributed about the horizontal axis.
Leonard's plot is definitely nonlinear.
The residuals show a good fit to a parabola.
This suggests that the relation between speed and fuel efficiency may be parabolic.
  
 
        
             
        
        
        
Hi!
The answer to your question is 9.75 minutes
Here is the math to prove it:
9+11+3+14+14+7+14+6=78
Now you will take 78 and divide it by 8
This is because when finding the mean you add all of the given number together and then divide them by the amount of number added together.
78/8=9.75
Thus, your answer is 9.75 minutes
I hope this helped!
Have a wonderful day/night!
God bless!
 
        
             
        
        
        
 Answer:
 Figure A
Step-by-step explanation:
It just moves position and nothing else it does´t rotate or anything. 
Definition of translation in math is: In Geometry, "Translation" simply means Moving ... ... without rotating, resizing or anything else, just moving.
Hopefully that is helpful to you. Have a wonderful day.
 
        
                    
             
        
        
        
The middle right is 145-90, so 55°. I'm not sure about the others
