Total Marbles = 8 + 6 + 12 + 10 = 36
Probability the marble is blue = 8/36
Inverse this to get the probability of the marble not being blue
Probability of the marble not being blue = 28/36 = 7/9
        
                    
             
        
        
        
First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6

Answer:
A. T > 2.539
Step-by-step explanation:
We have a hypothesis test of the mean, with unknown population standard deviation.
The hypothesis are:

From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.
The degrees of freedom can be calculated as:

The significance level is 0.01, so the critical value tc should be the one that satisfies:

Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
 
        
             
        
        
        
Answer:
6.
Step-by-step explanation:
 |2y-2| when y = 2
=  |2(-2)-2|
= |-4 - 2|
= |-6|
= 6.
