lawyer [12517]
The formula for determining the number of ways to select two pairs of sneakers from three pairs labeled A, B, and C is represented by 3C2 (3 combinations of 2), which calculates as 3! / (2!(3 - 2)!) = 3! / (2! x 1!) = (3 x 2) / (2 x 1) = 3. Therefore, the sample space is S = {AB, AC, BC}.

What is the factored form of a2 – 121?
AnnZ [12381]

Response:

The factored expression a^2-121 is (a+11)(a-11).

Detailed explanation:

Provided: a^2-121

Our goal is to express the given equation in a factored form.

Factoring pertains to rewriting an expression so that the product of its factors yields the original expression

Let’s consider the expression a^2-121.

We recognize the algebraic identity x^2-y^2=(x+y)(x-y)

Thus, we have a^2-121=a^2-(11)^2.

Matching with the above identity, we assign x= a, and b = 11, leading to

a^2-(11)^2=(a+11)(a-11).

Consequently, the factored expression a^2-121 is (a+11)(a-11).

A survey conducted five years ago by the health center at a university showed that 18% of the students smoked at the time. This
tester [12383]
The test statistic (Z) is 2.5767, and the p-value of the test is 0.009975. The null hypothesis suggests that the smoking rate among students has not changed, while the alternative indicates otherwise. The z-statistic for the sampled proportion is computed, yielding z ≈ 2.5767. As we investigate whether the smoking percentage has shifted over the preceding five years, the two-tailed p-value is found to be 0.009975. This result is significant at a 99% confidence level, demonstrating substantial evidence that the percentage of smoking students has changed.
