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}}}

If f(x)= mx+ c , f (1)=5 and f(-2)=-1​
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
