Answer:
AOD i think
Step-by-step explanation:
Volume of right triangular prism is bxhxL/2
So here it is 5x12x16/2 = 480
Answer:
![x=6](https://tex.z-dn.net/?f=x%3D6)
Step-by-step explanation:
![2+7x=5x+14](https://tex.z-dn.net/?f=2%2B7x%3D5x%2B14)
Subtract 2 from both sides:
![2+7x-2=5x+14-2](https://tex.z-dn.net/?f=2%2B7x-2%3D5x%2B14-2)
![7x=5x+12](https://tex.z-dn.net/?f=7x%3D5x%2B12)
Subtract 5x from both sides:
![7x-5x=5x+12-5x](https://tex.z-dn.net/?f=7x-5x%3D5x%2B12-5x)
![2x=12](https://tex.z-dn.net/?f=2x%3D12)
Divide both sides by 2:
![\frac{2x}{2}=\frac{12}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B12%7D%7B2%7D)
![x=6](https://tex.z-dn.net/?f=x%3D6)
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
Answer:
b = cd / a
Step-by-step explanation:
cd / b = a
cd = a * b
b = cd / a
