Answer: Mean = 5.25
Variance = 1.3125
Standard deviation = 1.456
Step-by-step explanation:
The mean and variance of a binomial distribution with parameters n (number of trials) and p ( the probability of getting success in each trial) is given by :-
Given : The total number of enter a clothing store : n=7
The probability of a customer making a purchase= 0.75
Now,
17∠x-11 set up the equation like this
28∠x add 17 to the other side, and you get x is greater than 28
60 minutes in an hour
60÷12=5
1,000 meter in 1 km
5×1=5
5×1000=5000
therefore, 5000 meters
