Answer:
4 lipsticks
Step-by-step explanation:
15+15=30, 30+30=60
Let m be mean
Mean= sum/ n
Mean= (1720+1687+1367+1614+1460+1867+1436) / 7
m= 11151 / 7
M= 1593
Mean= 1593
Standard deviation
|x-m|^2
For 1st: |1720-1593|^2=8836
For 2nd: |1687-1593|^2=10201
For 3rd: |1367-1593|^2=51076
For 4th: |1614-1593|^2=441
For 5th: |1460-1593|^2=1689
For 6th: |1867-1593|^2=75076
For 7th: |1436-1593|^2=24649
Summation of |x-m|^2 = 171968
Standard deviation sample formula is:
S.D = sqrt((summation of |x-m|^2) / n-1)
S.D=sqrt(171968/6)
S.D=sqrt(28661.33)
S.D=169.30
Standard deviation is 169.30
Answer:
I think its A
Step-by-step explanation:
The graph shows its number are getting greater than -4 and i think solid dots mean greater than or equal to the number
She would need to ride her bike more than 10.33 miles per day: x > 10.33
She has 62 miles left to ride for the week. To find the average per day, we just need to divide that amount by 6.
Dividing will give us 10 and one-third, or about 10.33.
