Answer:
A.) Eric rode 2 more miles per week than Kim rode
Step-by-step explanation:
A.) Eric rode 2 more miles per week than Kim rode
B.)Kim rode 3 more miles per week than Erick rode
C.) Kim rode 11 more miles per week than Erick rode
D.) Eric rode 17 more miles per week than Kim rode
Kim rode her biyciclye 135 miles in 9 weeks.
Number of miles Kim rode per week = Total miles travelled / number of weeks
= 135 miles / 9 weeks
= 15 miles per week
Eric rode her biciclye 102 miles in 6 weeks
Number of miles Eric rode per week = Total miles travelled / number of weeks
= 102 miles / 6 weeks
= 17 miles per week
The correct answer is
A.) Eric rode 2 more miles per week than Kim rode
Answer:
76.8
Step-by-step explanation:
Using the proportion
→ Percent is out of 100
= 
( cross- multiply )
100n = 7680 ( divide both sides by 100 )
n = 76.8
Answer:
The probability that 12 people in your sample are carrying no cash is 0.0712
Step-by-step explanation:
n = 100
p(no cash) = 0.09
x = 12
By applying binomial distribution
P(x,n) = nCx*px*(1-p)(n-x)
P(x = 12) = 0.074.
The probability that 12 people in your sample are carrying no cash is 0.074.
n = 100
p(less than 50) = 0.78
x = 75
By applying binomial distribution
P(x,n) = nCx*px*(1-p)(n-x)
P(x = 75) = 0.0712
The probability that 12 people in your sample are carrying no cash is 0.0712
