Answer:
0.8H - 24
Step-by-step explanation:
Normal price = H
Price off normal price = $30
Additional discount off = $20
Price after $30 off :
H - 30
price after discount of 20%
(100 - 20)% * (H - 30)
80% * (H - 30)
0.8 * (H - 30)
0.8H - 24
Answer:
The answer to your question is 42 m²
Step-by-step explanation:
Data
Base = 6 m
Height = 7 m
Formula
To calculate the area of a parallelogram just use the formula and substitute the values given, do not consider number 2.
Area = base x height
Substitution
Area = 6 x 7
Simplification and result
Area = 42 m²
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%
