Would this expression:

Ratling [72]

The given expression is a perfect square trinomial.

<h3>How to classify the given expression?</h3>

Here we have the expression:

$(x^2 - 16)^2$

Notice that we can rewrite it as:

$(x^2 - 4^2)^2$

Then we can see that inside the parenthesis we have a difference of squares, but it is squared, so if we define:

$x^2 = a\\4^2 = b$

We will have:

$(a - b)^2 = a^2 + -2ab + b^2 = (x^2)^2 - 2*(4^2)*(x^2) + (4^2)^2$

Which is in fact, a perfect square trinomial.

Apple products have become a household name in America with 51% of all households owning at least one Apple product (CNN, March

RSB [31]

Answer: It is mutually exclusive and exhaustive.

Step-by-step explanation:

Since we have given that

Owns apple No apple Total

With kids 500.2 319.8 820

Without kids 182.4 197.6 380

Total 682.6 517.4 1200

P(Households without kids) = $\dfrac{380}{1200}=0.316$

P(Households with kids) = $\dfrac{820}{1200}=0.683$

And P(A∪B) = 0.316+0.683 = 0.999 ≈ 1

Since the two event are disjoint so, the probability of both occurring is 0 and the probability of either occurring is the sum of each occurring.

Hence, it is mutually exclusive and exhaustive.
