I think you meant to say "scarce" and not "scare". If so, then the answer is D) natural
Anything that is common would be stuff you find everyday and it's everywhere. Scarce is the complete opposite, meaning rare or hard to find. An example would be a rock that is common and gold that is scarce.
Things that are human-made are the complete opposite of natural things such as water, or anything you would find out in nature without human intervention.
Answer:
y = x + 7
Step-by-step explanation:
3y - 3x = 21
3y/3 - 3x/3 = 21/3
y = x + 7
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:
250cm^3
Step-by-step explanation:
One mililiter of water has a volume of 1 cubic centimeter, or 1cm^3. Since there are 250 mililiters, there are 250 cubic centimeters of water.
Answer:
6 - 4i
Step-by-step explanation:
-4 + i = 10 - 5i
<u>+4 +4 </u>
i = 14 + 5i
<u>-5i -5i </u>
-4i = 14
i = -3.5
