Answer:
the answer would be F./_3
because they are corresponding angle
Answer: 267
Step-by-step explanation:
if we the prior proportion of population doesn't exist , then the formula to find the sample size is given by :-
Given : Confidence level : 0.95
Significance level : 
Critical value : 
Margin of error : 
Then , the required sample size will be :-
Hence, the minimum required sample size = 267
Answer:
10) (15, 2)
11) 5
12) positive
Step-by-step explanation:
Answer:
The equation is x² + y² = 144.
Step-by-step explanation:
This works the same way as before.
You know that at the origin, it equals (0, 0). So, we have no need to insert values for h and k. Therefore, it will just be x² + y² = r².
R is your radius, and this is given as 12 units. So, r = 12. Therefore, r² = 144.
Your final equation is x² + y² = 144.
You wouldnt get any solutions as if you substituted them into each other you would get:
-3x - 6 = -3x + 7
the -3x cancel eachother out so you end up with
-6 = 7 which isnt true
