Answer:

And we can find this probability like this:

And we can replace the values and we got:

Step-by-step explanation:
For this case we define the random variable Y as: the number of slices of cheesecake left on the platter after the first serving. And we have the following distribution for Y:
Y     |     0          1        2         3         4
P(Y) | 0.005  0.114  0.429  0.381  0.071
And we want to find the following probability:

And we can find this probability like this:

And we can replace the values and we got:

 
        
             
        
        
        
Answer:
 The value of y for x = 8 is 60  .
Step-by-step explanation:
Given expression as :
 For x = 2  , y = 15
Let the equation be written with constant k'
So, y = k x
Or, k = 
∴   k =  
<u>Now, again </u>
For x = 8 
equation can be written as 
    y = k x
Or,  y =  
 × 8
Or,  y = 
∴    y = 15 × 4
I.e  y = 60 
Hence The value of y for x = 8 is 60  . Answer
 
        
             
        
        
        
Answer:
7
Step-by-step explanation:
We have that x1=−1, y1=5, x2=3, y2=7.
Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=5−(12)(−1)=112
Finally, the equation of the line can be written in the form y=b+mx:
y=112+x2
