4n - 8 = n + 13
4n - n = 13 + 8
3n = 21
n = 21/3
n = 7....the number(n) = 7

Answer: p=0.711
Step-by-step explanation:
The binomial distribution probability formula :-
, where P(X) is the probability of success in x trials , p is the probability of success in each trial and n is the total number of trials .
Given : The probability of buying a movie ticket with a popcorn coupon is 0.711 and without a popcorn coupon is 0.289.
If you buy 21 movie tickets, we want to know the probability that more than 14 of the tickets have popcorn coupons.
Then, the event of success is tickets have popcorn coupons.
Hence, the parameter p for the given binomial distribution scenario : p=0.711
Answer:
56=29+a
Step-by-step explanation:
So 2 people gathered apples. That means there will be 3 numbers in the equation you are trying to make.
One number will be the amount of apples you gathered.
(as said, 29)
One number will be the amount of apples your friend gathered.
(you do not know this, so it will be a variable)
The last number will be the amount of apples you AND your friend gathered.
(as said, 56)
Since 56 is the amount of apples you and your friend gathered, its is equal to both other numbers combined.
to say that 56 is equal to both your apples and your friend's apples, you would say:
56 = 29 + a
(a is the variable)
To use this equation to find a, you would subtract 29 from both sides. It should look like:
27 = a
Z= 154
Explanation:
Multiply 14 by each side to get rid of it
14•14 cancel out
Then multiply 11•14 = 154
Bring down the Z
Therefore z=154
