Step-by-step explanation:
Given
There are seven trails with a probability of success is 

Using the binomial distribution, the Probability of exactly no success i.e. x=0 is given by

Answer:
2
just solve it and it will come out
3y (y is the unknown number but it represents one number only... and also 3y represents 3 multiply by y)
-x^2-x+y-6 Should be right
y=x^2-x-6 = x^2-x+y-6
Answer:
Negative
Step-by-step explanation:
If a line has a positive slope, then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.
