Answer:
SE = 0.025
Step-by-step explanation:
We are given;
Sample mean; x¯ = 14.52
Sample standard deviation; s = 0.075
Sample size; n = 9
Now,formula for standard error of sample mean is;
SE = s/√n
SE = 0.075/√9
SE = 0.075/3
SE = 0.025
First option because 3 x 10^9 is 3,000,000,000
Once you combine it, you get 10w + 18
You have to expand the expression so that it becomes
3m+3n
