Answer:
a) yes
b) ( 0.0280 , 0.1720 )
c) No
Step-by-step explanation:
A) Determine if the sample sizes are large enough
where :
ages between ( 18 to 29 )
p1 = 0.48 ,
n1 = 178 , ∴ n1 P1 = 85.44 also n1 ( 1 - p1 ) = 92.56
ages between ( 50 to 64 )
P2 = 0.03 ,
n2 = 427 ∴ n2p2 = 12.81 also n2( 1 -p2 ) = 414.19
<em>since all the values ae above 10 we can conclude that the sample sizes are large enough </em>
<em>answer = yes </em>
<u>B) Estimate the difference in the proportion of adult Americans aged 18 to 29</u>
= ( 0.0280 , 0.1720 )
attached below is the detailed solution
C) zero is not included in the interval
Answer:
Step-by-step explanation:
tan Θ + tan 2Θ + √3 tan Θ tan 2Θ = √3
tan Θ + tan 2Θ = √3 - √3 tan Θ tan 2Θ
tan Θ + tan 2Θ = √3 ( 1 - tan Θ tan 2Θ)
(tan Θ + tan 2Θ) / (1 - tanΘ tan 2Θ) = √3
tan(Θ + 2Θ) = √3
tan 3Θ = tan (
) we know tan Θ = tan α; Θ = nΠ + α, n belongs to z
3Θ = nΠ + Π/3
Θ = nπ/3 + Π/9 for all n in Z
Answer:
Total without the discount $52.50. Total with the discount $52.
Step-by-step explanation:
First, start by adding the 2 dollar discount to the total. Next remove the ten dollars for the Frequent Gamer card. This brings the total of the games to $210. Now all you have to do is divide by 4 and you have your answer. To get the answer with the discount skip the first step.
