Answer:
0
Step-by-step explanation:
=-5/6-7/6+2
=-12/6+2
=-2+2=0
This question is impossible to solve.
this is why:
if 4x-4=0
then x=1
so if 8x + 4 = 8
then x is false.
I get these question quite a lot in my GCSEs.
you have to prove why they are fake.
The equivalent expression is
.
We have the following expression -

We have to find its equivalent value.
<h3>What is the equivalent expression of the following expression-</h3>

In order to divide two exponents with same base, we use the 'Quotient property of exponents.
The equivalent expression can be written as -
f(x, y) = 
In the question given we have -
Using the property discussed above -
=
= 
Hence, the equivalent expression is
.

For given sample of salaries of four employees, the variance of their salaries is: 26 thousands of dollars
The formula for the variance is,

where,
= sample variance
= the value of the one observation
= the mean value of all observations
n = the number of observations
For given question,
n = 4
First we find the mean of their salaries.
(33 + 31 + 24 + 36 ) / 4 = 31
So, 
Using the formula for variance ,

Therefore, for given sample of salaries of four employees, the variance of their salaries is: 26 thousands of dollars
