Answer: 709
Step-by-step explanation:
The formulas we use to find the required sample size :-
1. 
, where 
= population standard deviation,
E = Margin of error .
z* = Critical value
2. 
, where p= prior estimate of population proportion.
3. If prior estimate of population proportion is unavailable , then we take p= 0.5 and the formula becomes
Given : Margin of error : E= 3% =0.03
Critical value for 95% confidence interval = z*= 1.96
A study conducted several years ago revealed that the percent of junior executives leaving within three years was 21%.
i.e. p=0.21
Then by formula 2., the required sample size will be :
[Round to the next integer.]
Hence, the required sample size of junior executives should be studied = 709

Answer: 6 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (20/2)^3
v = 4/3 x π x (10)^3 = 4,188.79 in3
Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.
4,188-79 / 693 = 6.04 = 6 fishes
Feel free to ask for more if needed or if you did not understand something.
Okay first
22x+11=5x-7
You need to move the variables so it eaquals 0
22x+11-5x+7=0
Now combine like terms
17x+18=0
Move 18 over to divide
17x=-18
X= -1.1 or just -1
Good luck! :D
