Answer:
2.5
Step-by-step explanation:
Answer: range= 26, variance= 80 and standard deviation= 8.94
Step-by-step explanation:
Range = highest - lowest
Range = 146 - 120
Range= 26
Let m be mean
M=mean=sum/n
Mean=(120+134+146+127+138+133) / 6
M=798/6
M=133
The standard deviation sample formula:
S.D = sqrt( Summation of |x-m|^2 / n-1)
Let start finding:
|x-m|^2
For 1st: |120-133|^2=169
For 2nd: |134-133|^2=1
For 3rd: |146-133|^2=169
For 4th: |127-133|^2=36
For 5th: |138-133|^2=25
For 6th: |133-133|^2=0
Summation of |x-m|^2 = 400
The standard deviation formula is :
S.D = sqrt( Summation of |x-m|^2 / n-1)
S.D= sqrt(400 / 5)
S.D=sqrt(80)
S.D= 8.94
Variance = (Summation of |x-m|^2 / n-1)
Variance= 400/5
Variance= 80
I believe x=2 because 6x=2x+8
Answer:
Step-by-step explanation:
51 / 13 = 3.9231 = 3
51 - (13 x 3) = 12
Answer:
63/9 = 7 -> Yes
-94 -> Yes
30/6 = 5 -> Yes
-16/3 ~ -5,33 -> Nope
-29,86 -> Nope
Step-by-step explanation:
Integers are whole Numbers.
For example 1,2,3,4,5...
The numbers between numbers are rational numbers.
Fir example:
1,2 ( between 1 and 2)
3,8 (between 3 and 4)
2,6 (between 2 and 3)
