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
To find the average, divide change in weight by change in weeks.
(149-134)/(8-13)
You should get a negative number, because he loses weight.
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
12,6,and 10 This Is Because the first two sides have to be longer than the third side .
