Answer:
The result is significant.
Step-by-step explanation:
Here,
p = 30 ÷ 330 = 0.091
thus, q = 1 - p = 0.909
Also, 
⇒ 
The z-score is:


Thus, at 95% confidence interval, p-value = 0.005
The result is significant at p < .05.
ANSWER

EXPLANATION
The given expression is

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.
This means that, we need to isolate d on one side of the equation while all other terms are on the other side.
We subtract from both sides of the equation to obtain,

We now divide through by -1, to get,

Or

The topic is change of subject
For example, lets take

We need to first factor the numerator and denominator to find the common numbers which we can simplify it by.

If we divide by 5 x 5 on both the numerator and denominator because both of them have it in common, we will get the simplest form.
Answer:
120
Step-by-step explanation:
