Empirical rule can be used to estimate the number of values that lie with 1, 2 or 3 standard deviations of a Normally distributed population.
According to the empirical rule, 95% of the values lie within 2 standard deviations of the mean.
Total number of bulbs = n = 560
95% of n = 0.95 x 560 = 532
This means, 532 bulbs will lie within 2 standard deviations from the mean
I think 375. Because he will stayed there for 5 days. The coast of room per night is 75 euro. 75×5=375. I hope it help you!
Dividing both sides by two,
OK, part 1.
When
then
Part 2.
When
then
(ab + 174)/3 <115
multiply by 3 on each side
ab + 174 < 345
subtract 174 from each side
ab < 171
248+ ab >366
subtract 248 from each side
ab> 118
Answer 118< ab < 171
