Answer:
 
 
And replacing we got:

Step-by-step explanation:
Let X the random variable of interest "number of craked eggs", on this case we now that:
 
The probability mass function for the Binomial distribution is given as:
 
Where (nCx) means combinatory and it's given by this formula:
 
And we want to find this probability:
 
And we can find the probability:
 
And replacing we got:

 
        
             
        
        
        
First, I would subtract 150 from 870. You get 720. Then I would divide that equally among the four artists. 720/4=180. So each person's share is $180.
        
                    
             
        
        
        
Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
 ...(1)
 ...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.
 
        
             
        
        
        
Answer:
No, Each input has one output
Step-by-step explanation:
A circle can't be a function because of its radius and diameter, its not linear so  it might have the same input or output. Therefore, you need a line to have a linear function .! 
Pls mark brainiest!
I hope you get this right!
