Answer:
s = sqrt [ Σ ( x i - x ) 2 / ( n - 1 ) ]
Step-by-step explanation:
where s is the sample standard deviation, x is the sample mean, x i is the ith element from the sample, and n is the number of elements in the sample. And finally, the standard deviation is equal to the square root of the variance.
Answer:
-1.81 is the least and 1 3/4 is the greatest
Step-by-step explanation:
1 3/4 is also 1.75 -1 4/5 is also -1.8
Ordered from least to greatest:
-1.81, - 1 4/5, -1.3, 1 3/4
Answer:
Step-by-step explanation:
We are given the following in the question:
The numbers of teams remaining in each round follows a geometric sequence.
Let a be the first the of the geometric sequence and r be the common ration.
The 
term of geometric sequence is given by:
Dividing the two equations, we get,
the first term can be calculated as:
Thus, the required geometric sequence is
There are 25 boxes and 15 of them are shaded.
15/25 = 0.6 = 60%
