Answer:
The combined standard deviation is 1.58114.
Step-by-step explanation:
The formula to compute the combined standard deviations of two different data sets is:

Here
is the combined mean given by:

It is provided that the sample size is same for both the data sets, i.e.
Compute the combined mean as follows:

Compute the combined standard deviation as follows:

Thus, the combined standard deviation is 1.58114.
"Step 1: log 3^(x+1) = log15" is the step among the following choices given in the question that she did incorrectly. The correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your desired help.
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 13 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 13 is 100%, so we can write it down as 13=100%.
4. We know, that x is 100% of the output value, so we can write it down as x=100%.
5. Now we have two simple equations:
1) 13=100%
2) x=100%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
13/x=100%/100%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 100% of 13
13/x=100/100
(13/x)*x=(100/100)*x - we multiply both sides of the equation by x
13=1*x - we divide both sides of the equation by (1) to get x
13/1=x
13=x
x=13
now we have:
100% of 13=13
