Answer:
Grandstand ticket = $380.
General admission ticket = $220
Step-by-step explanation:
Let the price of One grandstand ticket be X dollars and the price of One general admission ticket be Y dollars.
Then according to question,
6X + 2 Y = 2720 -(1)
Also,
4X + 4 Y = 2400 -(2)
Simplifying second equation we get ,
X + Y = 600 , Thus , X = 600 - Y .
Put X = 600 - Y in Equation 1.
So,
3600 - 6Y + 2Y = 2720
4Y = 880
Y = $220
Thus, X = 600 - 220 = $380.
So,
Cost of grandstand ticket is $380 and cost of general admission ticket is $220.
H, being an unknown number less than 30
30-h
you are taking away h because it is (h) amount less than 30
Given:
p = 47% = 0.47, the probability that a man considers himself a professional baseball fan.
q = 1 - p = 0.53, the probability that a man does not consider himself a professional baseball fan.
n = 10, the number of men surveyed.
(a) Calculate the probability that exactly 5 of 10 men surveyed consider themselves as professional baseball fans.
P(5 of 10) = ₁₀C₅ p⁵q⁵ = 252*0.47⁵*0.53⁵ = 0.242
Answer: 0.242 or 24.2%
(b) Calculate the probability of at least 6 out of 10.
P(at least 6 of 10)
= ₁₀C₆ p⁶q⁴ + ₁₀C₇ p⁷q³ + ₁₀C₈ p⁸q² + ₁₀C₉ p⁹q + ₁₀C₁₀ p¹⁰ q⁰
= 0.1786 + 0.0905 + 0.0301 + 0.0059 + 0.0
= 0.3057
Answer: 0.3057 or 30.6%
(c) Calculate the probability of less than 4 of 10.
P(less than 4 of 10)
= ₁₀C₁ pq⁹ + ₁₀C₂ p²q⁸ + ₁₀C₃ p³q⁷
= 0.0155 + 0.0619 + 0.1464
= 0.2238
Answer: 0.2238 or 22.4%
