That would be a / 3b^2

(re call that 1 /a^-1 = a)

In a set of 25 aluminum castings, four castings are defective (D), and the remaining twenty-one are good (G). A quality control

lianna [129]

Answer:

The sample space for selecting the group to test contains <u>2,300</u> elementary events.

Step-by-step explanation:

There are a total of <em>N</em> = 25 aluminum castings.

Of these 25 aluminum castings, <em>n</em>₁ = 4 castings are defective (D) and <em>n</em>₂ = 21 are good (G).

It is provided that a quality control inspector randomly selects three of the twenty-five castings without replacement to test.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!(n-k)!}$

Compute the number of samples that are possible as follows:

${25\choose 3}=\frac{25!}{3!\times (25-3)!}$

$=\frac{25\times 24\times 23\times 22!}{3!\times 22!}\\\\=\frac{25\times 24\times 23}{3\times 2\times 1}\\\\=2300$

The sample space for selecting the group to test contains <u>2,300</u> elementary events.

Simplify n^4 divided by n1/2

agasfer [191]

Given:

Consider the expression is

$\dfrac{n^4}{n^{\frac{1}{2}}}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\dfrac{n^4}{n^{\frac{1}{2}}}$

Using the properties of exponents, we get

$=n^{4-\frac{1}{2}}$ $\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]$

$=n^{\frac{8-1}{2}}$

$=n^{\frac{7}{2}}$

Therefore, the simplified form of the given expression is $n^{\frac{7}{2}}$ .
