Since <em>X</em> follows a binomial distribution, its mean and variance are
<em>np</em> = 3
<em>np</em> (1 - <em>p</em>) = 2
Substitute <em>np</em> = 3 in to the second equation to solve for <em>p</em> :
3 (1 - <em>p</em>) = 2
1 - <em>p</em> = 2/3
<em>p</em> = 1/3
Solve for <em>n</em> :
<em>n</em> (1/3) = 3
<em>n</em> = 9
The answer is W>33 this is as simplified at it can be
This equation has no horizontal asymptotes and has a vertical asymptote of x=pin
Answer:
m = 1
Step-by-step explanation:
y = x -3 and y = mx + b are the same thing
Since you have mx and x as the same thing, then m = 1 (for which slope is m)

4/7 - x = 6/35
You're trying to get x by itself, so you have to subtract 4/7 from both sides.
-x = 6/35 - 4/7
You need both of the fractions to the right of the equal sign to have the same denominator so that we could simplify them, so multiply 5/5 to -4/7.
-4 /7 × 5/5 = -20/35
So, our new equation is :
-x = 6/35 - 20/35
Simplify.
-x = -14/35
Divide both sides by -1.
x = 14/35
Divide by 7.
x = 2/5
