cannot be factored because no number can be multiplied to give you 3 and at the same time give you as

3 0

product & sum

what multiplies to 3 and adds to 1?

nothing, therefore this graphs doesn’t have any zeros

Answer:

Domain: ( − ∞ , ∞ ) , { x | x ∈ R}

Range: ( − ∞ , ∞ ) , { y | y ∈ R}

Step-by-step explanation:

We can simplify to understand how to answer the question better.

5 * 11x = 55x

Function range definition:

The set of values of the dependent variable for which a function is defined.

So the solution is..

-∞<x< ∞

And the interval notation is..

(- ∞. ∞)

Step-by-step explanation:

To find the E(X) expected value, you come up with the different probabilities for each outcome
your set of outcomes after 3 tosses would be = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} where H is heads and T is tails
Each element has a probability of 1/8 so let x represent number of tails
$Probability(x)=P(x)\\P(0)=\frac{1}{8} \\P(1)=\frac{3}{8} \\P(2)=\frac{3}{8} \\P(3)=\frac{1}{8}$
The E(x)=Summation (x times P(x))
$E(X)=(0)(0.125)+(1)(0.375)+(2)(0.375)+(3)(0.125)=1.5$
Now which probability is 1.5 tails? None, so it is either 2 tails or 1 tails
So you can expect to lose money in 1 game
But as you play more games the probability of getting 3 tails becomes more and more likely, so you can expect to win in a 100 games
