3 1/8 is the answer because 5x5=25 divided by 3 and you get roughly 24 with one left over so you put the one left over in a fraction hence 1/8.
have a nice day!
Answer:
1.691
Step-by-step explanation:
Standard error of the mean is expressed as SEM = S/√n
S is the population standard deviation
n is the sample size (number of observation)
Given S = 27 and n = 255
SEM = 27/√255
SEM = 27/15.97
SEM = 1.691
Hence the standard error of the mean is 1.691
Answer:
1.2
Step-by-step explanation:
1.2 is answer but you can simplify to 1 1/5
The y intercept is 3
-1/3 is the slope
