Subtract 4 from 9 because parentheses first.
Commutative property because it just moved around
Line m has no y int....so it does not cross the y axis....this means it is a vertical line with its equation being : x = 3.
line n has no x int...so it does not cross the x axis...means it is a horizontal line with its equation being : y = -4
Answer:
n=16
Step-by-step explanation:
m=9
solve for now where
n=25 -m
n=25-9
n=16
Answer: 2.71
Step-by-step explanation:
We know that the formula to calculate the standard error is given by :-
, where 
is the standard deviation and 'n' is the sample size.
Given : Standard deviation : 
Sample size : 
Then , the standard error of the mean is given by :-
Hence, the standard error of the mean = 2.71
