Answer:
25 / 676
Step-by-step explanation:
There are 5 vowels in the alphabets, and there are 26 alphabets in total as a whole.
The probability of drawing a vowel kb first trial is going to be
5 / 26, total number of vowels and total number of alphabets as a whole.
Again, we're told to replace the picked vowel, and pick another vowel, so that will once again be
5 / 26.
To get the final answer, we multiply both answers by each other
5 / 26 * 5 / 26 = 25 / 676.
Therefore, the probability has been found to be 25 / 676
The right answer is C. never
The quotient of two algebraic expressions is a<em> fractional expression.
</em> Moreover, the quotient of two <em>polynomials</em> such as:
![\frac{1}{x} \\ \\ \frac{3x-2}{1+x} \\ \\ \frac{x^2-4}{x^2+2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D%20%5C%5C%20%5C%5C%20%5Cfrac%7B3x-2%7D%7B1%2Bx%7D%20%5C%5C%20%5C%5C%20%5Cfrac%7Bx%5E2-4%7D%7Bx%5E2%2B2%7D)
is called a rational expression. So according to this definition rational expressions does not contain logarithmic functions. In fact, a rational expression is an expression that is the ratio of two polynomials like this:
![f(x)=\frac{P(x)}{Q(x)} \\ \\ with \ Q(x) \neq 0](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7BP%28x%29%7D%7BQ%28x%29%7D%20%5C%5C%20%5C%5C%20with%20%5C%20Q%28x%29%20%5Cneq%200)
To evaluate when plugging in numerical values for variables, simply put the numerical values in the place of the corresponding variables:
![V = \pi \cdot 3^2 \cdot 5](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cpi%20%5Ccdot%203%5E2%20%5Ccdot%205%20)
![\boxed{V = 45\pi \approx 141.37}](https://tex.z-dn.net/?f=%20%5Cboxed%7BV%20%3D%2045%5Cpi%20%5Capprox%20141.37%7D%20)
