I think that is the mean or the mode . I think more on mean
Complete Question:
Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.
Answer:

Step-by-step explanation:
<em>See comment for complete question</em>
Given


Required
Determine how they can show if the products are the same or not
To do this, we simply factorize each polynomial
For, Polynomial A: We have:

Factor out 4x

Apply difference of two squares on x^2 - 4

For, Polynomial B: We have:

Expand x^2 + x - 2

Factorize:

Factor out x + 2

Factor out 4x

Rearrange

The simplified expressions are:
and

Hence, both polynomials are equal

The theoretical probability of getting heads or tails is 1/2 the time.
1/2 of 150 = 75
So theoretically you would get 75 heads and 75 tails.
The experiment got 84 heads, which is greater than 75, so it would be higher than the theoretical probability.
The answer is : <span>It is 6% higher than the theoretical probability.</span>
