Answer:

The answer is that w = 24

Step-by-step explanation:

In order to find this, add 9 to both sides.

w - 9 = 15

w - 9 + 9 = 15 + 9

w = 24

I don’t understand what I’m supposed to do with this question ( Evaluate: log125^5) ?

Juliette [100K]

Step-by-step explanation:

$log_{125} \: 5 \\ \\= \frac{log \: 5 }{log \: {125}} \\(By \: change\:of \:base\:law) \\\\ = \frac{log \: 5 }{log \: { {5}^{3} }} \\ \\ = \frac{log \: 5 }{3 \: log \: { {5}}} \\ \\ = \frac{1}{3} \\ \\ \huge \red { \boxed{ \therefore \: log_{125} \: 5 = \frac{1}{3}}}$

taurus [48]

Answer:

$y = 2x + 3$

Step-by-step explanation:

We can find the slope.

$\frac{ 5 + 1}{1 + 2 } = 2$

so m is 2

$y = 2x + c$

Plug one the equations in to find c.

$- 1 = 2( - 2) + c$

$- 1 = - 4 + c$

$3 = c$

so the equation is

$y = 2x + 3$

A man has n keys on a key ring, one of which opens the door to his apartment. Having celebrated a bit too much one evening, he r

schepotkina [342]

Answer:

The value is $P(3) = \frac{1}{n}$

Step-by-step explanation:

From the question we are told that

The number of keys is n

The number of keys remaining after the first key is chosen is n-1

The probability that he gains entrance with the first key he selects is $\frac{1}{n}$

Generally the probability that the first key does not open the door is

$p(F_1) = 1 - \frac{1}{n} = \frac{n-1}{n}$

Generally the number of keys remaining after the second key is chosen is

n-2

Generally the probability that he gains entrance with the second key he selects is

$\frac{1}{n-1}$

Generally the probability that the second key does not opens the door is

$P(F_2) = 1- \frac{1}{n-1} = \frac{n-2}{n-1}$

Generally the probability that he gains entrance with the third key he selects is

$\frac{1}{n-2}$

Generally the probability that the door opens with the third key

$P(3) = p(F_1) * P(F_2) * \frac{1}{n-2}$

=> $P(3) = \frac{n-1}{n} * \frac{n-2}{n-1} * \frac{n-2}{n-1}$

=> $P(3) = \frac{1}{n}$

Note :

All the outcome of the events are independent
