Answer:
simplify -1(3/5)÷(-2/3) = 9/10
=90/100
= .90 and there's your answer
To get the answer to this problem you first factor out the common term 2
(n+3)/(2(n-3) ) * (n+3)/(3n-9)
then factor out the common term 3
(n+3)/(2 (n-3) ) * (n+3)/(3 (n-3) )
then simplify
( (n+3)(n+3)/(2 (n-3)*3(n-3) )
Use product rule : x^a x^b= x^a+b
( (n+3)^2/(2 (n-3)*3(n-3) )
simplify 2 (n-3) * 3(n-3) to 6(n-3)(n-3)
( (n+3)^2/(6 (n-3)(n-3) )
use product rule again : x^a x^b=x^a+b
so you get the answer : ( (n+3)^2)/(6 (n-3)^2 )
so the orrect answer to this problem is answer choice (C)

Answer:
a) 0.00070
b) 0.00050
c) 0.00022
d) 0.00016
e) 0.00005
Step-by-step explanation:
Standard error for proportion formula
S.E = √P(1 - P)/n
Where P = proportion
n = number of samples
Assume that the population proportion is 0.46. Compute the standard error of the proportion, σp, for sample sizes of a) 500,000
S.E = √P(1 - P)/n
= √0.46 × 0.54/500000
= √ 4.968 ×10^-7
= 0.0007048404
≈ 0.00070
b) 1,000,000
√P(1 - P)/n
= √0.46 × 0.54/1000000
= 0.0004983974
≈ 0.00050
c) 5,000,000
√P(1 - P)/n
= √0.46 × 0.54/5000000
= √ 4.968 ×10^-8
= 0.0002228901
≈ 0.00022
d) 10,000,000
√P(1 - P)/n
= √0.46 × 0.54/10000000
= √2.484 ×10^-8
= 0.0001576071
≈ 0.00016
e) 100,000,000
√P(1 - P)/n
= √0.46 × 0.54/100000000
= √2.484 × 10^-9
= 0.0000498397
= 0.00005
