7+3=10 because it’s asking for something that adds 3 and that would equal 10 so the proper equation is 7+3=10 :)

If the standard deviation of a set of data is zero, what can you conclude about the set of values? The sum of the deviations fro

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.

What is the area of this triangle?

dsp73

Answer:60

Step-by-step explanation:

a=13 b=13 c=10

Perimeter of =a+b+c

perimeter of =13+13+10

Perimeter of =36

S=36 ➗ 2

S=18

Area=√s(s-a)(s-b)(s-c)

Area=√18(18-13)(18-13)(18-10)

Area=√18(5)(5)(8)

Area=√(3600)

Area of =60
