Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
I think it’s C. Im not completely sure.
Not sure what you mean, exactly, but Ill try.
668, using 2 ones, go to 670. Using 3 tens, go to 700. Using 2 hundreds get to 900. Hope this helped :)
2(l+w)=16
l+w=16:2
l+w=8
for l>w
l=7, w=1
l=6, w=2
l=5, w=3
