The standard error of the mean is 12.
The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.
The standard error S.E of the mean can be calculated by using the formula:
where;
- standard deviation = 24
- sample size n = 4
S.E = 12

Answer:
Step-by-step explanation:
This is a geometric mean problem...a ratio. The geometric mean is the height of the triangle, 6. To solve:
and cross multiply to solve for x:
3x = 36 so
x = 12
The student wants to prove they are the same by adding the two systems together, and keeping the second equation the same.
So add these two:
6x - 2y = 3
<u>5x + 3y = 4</u>
11x + y = 7
So the answer will be the last choice:
<span>Show that the solution to the system of equations 11x + y = 7 and 5x + 3y = 4 is the same as the solution to the given system of equations</span>
