Use the attached formula.
Years = ln (200 / 100) / .034
Years = ln (2) / .034
Years = 0.69314718056 / .034
Years =

Answer:
C) 201
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
Assuming n > 30, we can approximate CV with a normal distribution. At P = 99%, CV = 2.576.
SE = σ / √n
SE = 1100 / √n
Therefore:
200 = 2.576 × 1100 / √n
n = 201
Ben got the five and the six mixed up in the report. He can fix this by writing 5,650,000 instead.
If x =-3 that means the equation becomes
Y=2(-3) +1 and when you simplify you get
Y=-5 hope this helps :)
