Answer:
5n^2+(4n)-1
Step-by-step explanation:
(5n-1)(n+1)=0
Lets find <em>n.</em>
(5n-1)(n+1)=0
FOIL it.
5n^2+5n-1n-1
Add/Substract similar factors
5n^2+(5n-1n)-1
5n^2+(4n)-1
Thats your answer.

Answer:
Test statistic = 2.8965
Step-by-step explanation:
The test statistic is given by the formula
z = (x - μ)/σₓ
μ = mean = 0.799
x = proportion of literate people in Tamil Nadu = (983/1185) = 0.8295
σₓ = standard error of this calculated proportion = √[p(1-p)/n]
= √(0.8295 × 0.1705/1185) = 0.01093
z = (x - μ)/σₓ
z = (0.8295 - 0.799)/0.01093 = 2.8965
z = 2.8965
