Answer:
=£1970
Step-by-step explanation:
10%=£360
5%=£190
40%=£1440
45%=£1630
£3600-£1630=£1970
Formula applied: p+/- Z*sqrt (p(1-p)/N)
Where
p=probability of those who will vote for candidate a = 120/400 = 0.3
Z = Critical value at 95% confidence interval = 1.96
N = Size of the sample = 400
Substituting;
Interval = 0.3+/- 1.96* sqrt (0.3(1-0.3)/400) = 0.3+/-0.045
Interval of population who will vote for candidate a at 95% confidence interval
= 0.3+0.045 to 0.3-0.045
=0.345 to 0.255 of the total population
Area = length*width
Width = area/length
width = (65 1/4 in^2)/(9 2/3 in)
width = 6 3/4 inches
Hope this helps :)
10 : 6
The ratio is already in lowest terms so I found an equivalent ratio by multiplying both terms by 2.
