Answer:

There's only one solution x = 2

Thr solution x = 1 is an extraneous solution.

Step-by-step explanation:

\frac{1}{x - 1}  +  \frac{2}{x}  =  \frac{x}{x - 1}  \\  \frac{2}{x}  =  \frac{x}{x - 1}  -  \frac{1}{x - 1}  \\  \frac{2}{x}  =  \frac{x - 1}{x - 1}  \\  \frac{2}{x}  = 1 \\ 2 = x

On a test that has a normal distribution, a score of 49 falls two standard deviations below the mean, and a score of 61 falls on
Zolol [24]

The mean of this test will be 57.

<h3>What is Standard Deviation and Mean?</h3>

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

The mean can be used to get an overall idea, or picture, of the data set.

Let Mean be 'm'

and standard deviation= \sigma

So, m-2\sigma=49

and, m + \sigma=61

Solving the above two equation we get

\sigma =4

Now, m= 61-\sigma

           = 61-4

           = 57

So , the mean of this test will be =57
