The answer i believe would be A .because if you dived 6.98 by the 3.86 it becomes 1.8082 so on and so forth so you round and since there’s a 8 after the zero you round the zero to a one so it would be 1.81
The correct answer would be D) 4.8x + 1.2 = 3.6; x = 0.5 mile
Step-by-step explanation:
This is because laps would be the dependent variable, so we know the number of them (4.8) would be multiplied by the variable (x). We also know that 1.2 is the constant. Now we can solve to make sure this is the right equation.
4.8x + 1.2 = 3.6
4.8x = 2.4
x = 0.5

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
