Answer:
1445 mg
Step-by-step explanation:
If you go from 2009 to 2011 and decayed 390 mg, you divide that by two to see how much it decays in one year. After you get that, you multiple 195 by 5 and get 975. your initial value is 480, so you would add 975 and 480 to get the answer 1445 mg. I am only in the 7th grade, so I could be wrong but it looks like a simple slope problem and I feel pretty confident about my answer.
Answer:
1067
Step-by-step explanation:
Given that:
Error (E) = 0.03
Confidence interval = 95% = 0.95
Sample size (n) = ((Zα/2) / Error)^2 * p(1 - p)
Since no assumption is given ; p = 0.5
α = 0.95
Z(1-α/2) = 1.96
(1.96 / 0.03)^2 * 0.5(1 - 0.5)
(65.333333)^2 * 0.5(0.5)
4268.4444 * 0.25
= 1067.1111
n = 1067
