What is the probability of getting an even number on the roll of a six-sided die? 1/6 1/3 1/2

givi [52]

Answer: 1/2

Step-by-step explanation:

The sample space when a six sided die is thrown once is :

{ 1,2,3,3,5,6}

The even numbers are :

{2,4,6}

Therefore :

P(even) = n(even) / total number

That is

P(even) = 3/6

P(even) = 1/2

If (-2, y) lles on the graph of y = 3^x, then y =

sweet [91]

<h3>Answer:</h3>

$\frac{1}{9}$

<h3>Step-by-step explanation:</h3>

We know that $x=-2$ , so substitute that into the equation. $y=3^{-2}$

With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking, $x^{-y}=\frac{1}{x^y}$ . This makes our equation: $y=\frac{1}{3^2}$

Finally, simplify the exponent. $y=\frac{1}{9}$

Can someone please help with this math question:)

Bingel [31]

<u>Solution</u><u>:</u>

The rationalisation factor for $\frac{1}{ a - \sqrt{b} }$ is $a + \sqrt{b}$

So, let us apply it here.

$\frac{1}{5 - \sqrt{2} }$

The rationalising factor for 5 - √2 is 5 + √2.

Therefore, multiplying and dividing by 5 + √2, we have

$= \frac{1}{5 - \sqrt{2} } \times \frac{5 + \sqrt{2} }{5 + \sqrt{2} } \\ = \frac{5 + \sqrt{2} }{(5 - \sqrt{2})(5 + \sqrt{2} ) } \\ = \frac{5 + \sqrt{2} }{ {(5)}^{2} - ( \sqrt{2})^{2} } \\ = \frac{5 + \sqrt{2} }{25 - 2} \\ = \frac{5 + \sqrt{2} }{23}$

<u>Answer:</u>

Hope you could understand.

If you have any query, feel free to ask.
