mezya [45]

Answer:

 Number of containers = 271

 Number of strawberries left = 4

Explanation:

Total number of strawberries = 2172.

Number of strawberries per container = 8

Number of strawberry container =  Total number of strawberries/Number of strawberries per container.

Number of strawberry container = 2172/8

 Refer the figure to see division,

 Number of containers = 271

 Number of strawberries left = 4

What is the standard deviation of the following data? 52 61 31 44 47 45 25 48 47
Elena-2011 [213]
Standard deviation is calculated by
1. calculate mean, m
2. calculate deviation of EACH entry of data set from the mean, i.e.
d=(x-m)
3. calculate mean of square of deviations (d^2)/n to get variance,v
4. take square-root of variance to get standard deviation.

For example,
To find the standard deviation of data set {3,7,8}
1. mean=(3+7+8)/3=6
2. deviations, di={3-6,7-6,8-6}={-3,1,2}
3. squares of deviations, di^2={9,1,4}
4. mean of squares of deviations=(9+1+4)/3=14/3
Standard deviation=sqrt(14/3)=2.16

For the given data set, if you follow the above steps, you would get
sum=400
mean=400/9
variance (mean square of deviations)=8246/81
standard deviation=sqrt(8246/81)=sqrt(8246)/9
