Answer:

$Expression = 7 + x + 5$

$Simplified = 12 + x$

Step-by-step explanation:

Required:

Write as an expression and simplify

The sum of a number, x and 5 can be represented as: x + 5

So, the expression becomes: 7 + x + 5

$Expression = 7 + x + 5$

Solving further:

Collect Like terms

$Expression = 7 + 5 + x$

Add like terms

$Expression = 12 + x$

Hence, the simplified expression is: 12 + x

Rashid [163]

Answer:

All values are identical.

Step-by-step explanation:

We are given the following in the question:

If the standard deviation of a set of data is zero.

Then, all the values in data are identical.

This can be shown as:

Let all the terms in data be x.

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{nx}{n} = x$

Sum of squares of differences =

$\displaystyle\sum (x_i - x)^2 = 0$

$\sigma = \sqrt{\frac{0}{n}} = 0$

Thus, the correct answer is

All values are identical.
