I think the correct answer is C. i hope this helps
Hey, here's a pic of it ! hope this helps !
p.s., photomath is a good app for algebraic answers with work, you should check it out (:
Here, your equation is x + y = 6
In order to calculate coordinates, put x = 0,
0 + y = 6,
y = 6
Now, put y = 0, x + 0 = 6
x = 6
So, Your Coordinates would be: (0, 6) & (6, 0)
Hope this helps!

Answer: 2172
Step-by-step explanation:
Formula to find the sample size n , if the prior estimate of the population proportion(p) is known:
, where E= margin of error and z* = Critical z-value.
Let p be the population proportion of adults have consulted fortune tellers.
As per given , we have
p= 0.20
E= 0.02
From z-table , the z-value corresponding to 98% confidence interval = z*=2.33
Then, the required sample size will be :
Hence, the required sample size = 2172
