Answer:
there were 82 adult tickets and 32 children tickets that were sold
Step-by-step explanation:
x = adult's tickets
y = children's tickets
x + y = 114
y = -x +114
replace y by -x +114 in the second equation
11x + 6y = 1094
11x + 6(-x + 114) = 1094
11x -6x + 684 = 1094
5x + 684 = 1094
5x = 410
x = 82
x + y = 114
82 + y = 114
y = 32

Binomial probability distribution concept & application, example
Step-by-step explanation:
Yes, this represents a binomial setting. As, it is used for finding probability of - particular number of success outcomes , from repetitive or multiple events.
Here
- Success {Event P} ie small fish, with prob = 30% = 0.3 .Failure {Event Q} ie large fish, with prob = 70% = 0.7
- Number of trials = 20. Let r be number of small fishes out of 20 fishes.
Binomial probability = N c r . (P)^r . (Q)^ (n-r)
Ex : P( 5 small fish out of 20) = 20c5 (0.30)^5 (0.70)^15
Answer: $171.31
<u>Step-by-step explanation:</u>
A = P(1 - r)ⁿ
Given: P = 200, r = 1.1% (.011), n = 14
A = 200(1 - .011)¹⁴
= 200(.989)¹⁴
= 171.308
Since we are talking about money, round to two decimal places.
