Answer:
m = n = 2
Step-by-step explanation:
(m + n√2)(1 - √2)² = -2 + 2√2
(m + n√2)(1 - 2√2 + 2) = -2 + 2√2
(m + n√2)(3 - 2√2) = -2 + 2√2
3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2
(3n - 2m)√2 + 3m - 4n = 2√2 - 2
3n - 2m = 2
4n - 3m = 2
3n - 2m = 4n - 3m
n = m
4n - 3n = 2
n = 2
m = 2
Hope this helps.
Note that 60 minutes is 1 standard deviation away from the mean and from recalling the 68-95-99.7 rule, the area that will remain is (100 - 68) = 32%. However, we only want the leftmost portion of this area, so the answer is 32%/2 = 16%.
