Answer:
18
Step-by-step explanation:
50 - 32 = 18
Answer:( c ) 1.414
Step-by-step explanation:
Let m be mean
M=mean=sum/n
M= (16+19+18+17+20+18) / 6
M=108/6
M=18
Let start finding:
The standard deviation formula is= sqrt( Summation of |x-m|^2 / n-1)
|x-m|^2
For 1st: |16-18|^2=4
For 2nd: |19-18|^2=1
For 3rd: |18-18|^2=0
For 4th: |17-18|^2=1
For 5th: |20-18|^2=4
For 6th: |18-18|^2=0
Summation of |x-m|^2 =10
The standard deviation formula is :
S.D = sqrt( Summation of |x-m|^2 / n-1)
S.D= sqrt(10 / 5)
S.D=sqrt(2)
S.D= 1.414
3/8 + 2/8 = 5/8
8/8 - 1/8 = 7/8
7/8 - 5/8 = 2/8 = 1/4
he used 1/4 to paint the bird house.
