The answer is c. Because insert x=2 into the equation and 2x2=4-3=1 sooo f(x)=1
Answer:
I think question is:
(x+4x+2)(2x^2+3x-4)
:(5x+2)(2x^2+3x-4)
5x(2x^2+3x-4)+2(2x^2+3x-4)
10x^3+15x^2-20x+4x^2+6x-8
10x^3+19x^2-14x-8
Answer:
Step-by-step explanation:
Given a binomial experiment with n trials and probability of success p,
Since each term of the summation is multiplied by x, the value of the term corresponding to x = 0 will be 0. Therefore the expected value becomes:
Now,
Substituting,
Factoring out the n and one p from the above expression:
Representing k=x-1 in the above gives us:
This can then be written by the Binomial Formula as:

8) I got x=1
Step-by-step explanation:
So sorry if that is wrong
First, you would multiply: -13 = 70m - 2m. Then, you subtract the like terms, which would be 70m - 2m: -13 = 68m. You are looking for what m is, so you would divide 68 on both sides: m = - 13 / 68. In math, people would usually like fractions more than decimals, but if you are looking for the decimal number, it would be m ≈ - 0.19.
