If you look at the graph of sin(n), you can notice that it oscillates every kpi/2 when k is odd. This oscillation proves that sin(n) diverges.
If its the one under the one with a written answer(the first on blank at the top) its b. 20% did not arrive.
I believe that correlation without causation is the number of doctors
Correlation with causation is the number of high school seniors. Hope this helps!
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)
Simplify it to 6v=12
divied 12 by 6
v=2
