We are given the following equation and want to find the possible values of x
Subtract both sides by 3x
Now, we have this weird equation. Since -15 is NOT equal 15 and there is no other way we could have solved for x, there is no real solution to the given equation.
In other words, there is no value of x that makes the equation true.
Let me know if you need any clarifications, thanks!

The equation for area of a trapezoid is
Substituting our values in
We can then simplify the expression
Answer:
12.1, 12.3,12.4,12.5,12.3,12.1,12.2
And for the standard deviation we can use the following formula:
And after replace we got:
And as we can ee we got a small value for the deviation <1 on this case.
Step-by-step explanation:
For example if we have the following data:
12.1, 12.3,12.4,12.5,12.3,12.1,12.2
We see that the data are similar for all the observations so we would expect a small standard deviation
If we calculate the sample mean we can use the following formula:
And replacing we got:
And for the standard deviation we can use the following formula:
And after replace we got:
And as we can ee we got a small value for the deviation <1 on this case.
