Answer:

The standard error of the proportion is 0.112.

Step-by-step explanation:

The standard error of a proportion is given by the following formula:

$S = \sqrt{\frac{p(1-p)}{n}}$

In which p is the probability of a success and n is the length of the sample.

In this problem

A success is a student defining themselves regular dietary supplement users. Our of 3000 students, 1500 do. So $p = \frac{1500}{3000} = 0.5$ .

We take a sample of 20 of them, so $n = 20$ .

$S = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.5*0.5}{20}} = 0.112$

How many solutions does 4(y-30)=4y+12

Anit [1.1K]

$\text{Solve for y:}\\\\4(y-30)=4y+12\\\\4y-120=4y+12\\\\\text{Subtract 4y from both sides}\\\\-120=12\\\\\text{You would see that the y variable is now non-existent}\\\\\text{This means that there are no solutions}\\\\\boxed{\text{No solutions}}$
