-572.85 i just took the test and got it right
Basically meaning that no model can exactly be on point with whatever it is modeling. Two things cannot be EXACTLY identical to what they are referring to, but it is saying that some can get close enough to be useful as an example.
Answer:
40% chance
Step-by-step explanation:
4 marbles out of 10 are red. 4/10= 0.4= 40%
The number of whole number is 23 through subtracting the numbers. hope it helps ☺️
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
