Answer:
43
Step-by-step explanation:
Answer:
£12.60
Step-by-step explanation:
let the cost of a child ticket be x then the cost of an adult ticket is x + 6
Sum the costs and equate to 45
x + 6 + x + 6 + 3x = 45 , that is
5x + 12 = 45 ( subtract 12 from both sides )
5x = 33 ( divide both sides by 5 )
x = 6.6
Cost of and adult ticket = x + 6 = 6.60 + 6 = £12.60
Answer:
a) This will result in a binomial distribution.
b) This will not result in a binomial distribution.
Step-by-step explanation:
Binomial probability
The binomial probability is the probability of exactly x successes on n repeated trials, and each trial can only have two outcomes.
So:
(a) The National Health Institute checks on 100 people who had a certain type of cancer in the year 2000 and records whether they are alive or not.
Fixed number of trials(each person checked is a trial) with a fixed probability(there is a probability that the person who had that type of cancer is alive).
So it results in a binomial distribution.
(b) Calling all your friends until you have 2 people willing to play on your volleyball team.
There is not a fixed number of friends that are going to be asked, so this does not results in a binomial distribution.
To complete this question, you would do
this equals 0.205 per apple, or 0.21 if rounded to 2 decimal places
