The Binomial distribution is a sequence of N trials which each have a probability, p, of occurring. Each trial is either successful (with probability p) or not. It can be used to give us the probability o...

X^2 - (4*3) + 8 = 0
X^2 -4 = 0
X^2 = 4
X = 2

For a simple integration like this, begin by expanding the brackets to get 2x³-6x²+4x-12. Next each term should be integrated with respect to x, begin with the first term, each peer ...

There's a lot of information to take on in this question so it's firstly important to isolate the facts: ...

Step 1: x+y=7 can be rearranged as: x= 9 - y.Step 2: We substitute the expression of x in the second equation: 9 - y - 2y + 1 = 1Step 3: We calculate the value of y. 9 + 1 - 1- 3y=0. It is equivalent with...
