Old - new is 1 so than after that it would be 1/5 than 1/5 x 100 = 20%
Answer:
r (100) = 10*p (10)
Step-by-step explanation:
r= 100 pieces of candy
10=10
p=10 pieces of candy
r (100) = 10*p (10)
Answer: It might be a no answer. I don't know which one. I'm so sorry if I'm wrong.
Answer:
V≈ 863.27 in³
Step-by-step explanation:
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
