That is just multiply the number of choices for each
5 colors
2 lengths of sleaves
3 colors
5*2*3=30
answer is 30
C is answer
Answer:x=8
Step-by-step explanation:
Total Volume is given as 1080 cubic feet.
Height is given as 9 feet.
Length is 2 feet longer than the width, so Length = x+2
If the stall is 10 feet wide, then the length would be 10 +2 = 12 feet.
The volume for that would be 10 x 12 x 9 = 1080 cubic feet.
Yes it is possible for the width to be 10 feet.
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
