Answer:
The standard error of a proportion p in a sample of size n is given by: 
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation
In this question:
The standard error of a proportion p in a sample of size n is given by:

Essentially just turn the big number into an exponent so u can cancel out and be left with just the x for example 128 is the same as 2^7 and when you have it like that you simply cancel the 2 and are left with x=7
A) x=7
B) x=6
C) x=4
D) x=8
E) got cut off theres no value
F) x=2
G) x=3
Id reccomend downloading photomath for these type of questions or symbolab on your phone it shows the steps but try practicing it first :)
A = 30 degrees or pi/6 radian
o = 60 degrees or pi/3 radian
Sorry man, it’s a tough time for figure out
Use this paper and examine the steps. This will help you understand the trigs formula to solve for each.
