N.linear! hope this helps!
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 73
The proportion that in favor of raising the tuition is 
The standard deviation is 
The required standard deviation 
Generally the requires standard deviation is mathematically represented as

=> 
=> ![\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2](https://tex.z-dn.net/?f=%5Cfrac%7Bn_1%7D%7Bn_2%7D%20%3D%5B%5Cfrac%7Bs_2%7D%7Bs_1%7D%20%5D%5E2)
=> ![\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2](https://tex.z-dn.net/?f=%5Cfrac%7B73%7D%7Bn_2%7D%20%3D%5B%5Cfrac%7B0.047%7D%7B0.098%7D%20%5D%5E2)

Answer:
Long part= 45
Short part= 25
Step-by-step explanation:
Let the short part of the stick be x
Let the long part be x+20
The total length of the stick is 70cm
x + (x+20)= 70
x+x+20= 70
2x+20= 70
2x= 70-20
2x= 50
x= 50/2
= 25
Longer part length= 20+25
= 45
The short part is 25
Your answer is X= -1
you have to move terms first to get this
8x-5=2x+1
then collect like terms and calculate sum
8x-2x=1+5
lastly you divide both sides by 6
X=1
HOPE THIS HELPS! :)
