Ok, so we need to take 60 x 60. That gives us 3600, which is the amount of seconds in 60 minutes. Then we need to take 3600 x 24, to figure out the number of seconds in 24 hours (1 full day). That gives us 86,400. Finally, we take 86400 x 365, to determine how many seconds are in 1 full year (365 days). That gives us the answer of <span>31536000. Hope this helps!</span>
Answer:
I should use at least 304 students
Step-by-step explanation:
Margin error (E) = t × sd/√n
E = 40
sd = 300
confidence level (C) = 98% = 0.98
significance level = 1 - C = 1 - 0.98 = 0.02 = 2%
t-value corresponding to 2% significance level and infinity degree of freedom is 2.326
n = (t×sd/E)^2 = (2.326×300/40)^2 = 17.445^2 = 304 (to the nearest integer)
ANSWER:
6 cents
Step-by-step explanation:
