Answer:
p(s) = 0,33
Step-by-step explanation:
n = 450
p₀ = 150/450 p₀ = 0,33 then q₀ = 0,67
n*p₀ = 0,33*450 = 150
n*q₀ = 0,67*450 = 301
n*p₀ and n*q₀ more than 10, we can approximate the binomial to a Normal Distribution Distribution
a) p - p₀ = z(c) * √ (p₀q₀)/n
z(c) = ??
CI 95 % then α = 5 % α = 0,05 α/2 = 0,025
z(c) = 1,96
p = p₀ ± z(c) * √ (p₀q₀)/n
p = 0,33 ± 1,96 * 0,022
p = ( 0,33 - 0,04 ; 0,33 + 0,04
p = ( 0,29 ; 0,37 )
The value of the center of the confidence Interval is 0,33
p(s) = 0,33
Answer:
This is an percentage change question, by any chance you have a maths textbook, search for units that contains the topic: Percentage Change/Percentage. Now, let's get solving! :D
Step-by-step explanation:
First of all, you multiply 7% with $778,095 which gives: $54,466.65 (This is your commission/Answer)
<em><u>Most currency questions use 1 decimal place,</u></em><em><u> </u></em><em><u>so</u></em><em><u> </u></em><em><u>I recommend you to use this answer: $54,466.7</u></em>

Answer:
60 X 130/100=78
answer:78
Step-by-step explanation:
The rate that train 1 is going plus the distance:
35x+52.5
The rate that train 2 is going plus the distance:
56x+0
X=number of hours
Solve for X to find where the 2 trains have gone the same distance:
35x+52.5=56x
52.5=21x
2.5=x
The express train will overtake the local train 2 and a half hours after it leaves
