Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation
Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320
The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).

Answer:
-0.6666.... = -
Step-by-step explanation:
Repeating decimals can be written as either 0.6666..., or as 0.6 with a small line over the top of the 6 to indicate it repeats. Repeating fractions are not put into fractions in the traditional way. If we had the terminating decimal 0.4, then we know to put the 4 over 10 and reduce:
However, with repeating decimals, instead of putting the number of the decimal over a value of 10, we put it over a value of 9. So, for the equivalent fraction form of -0.6 (repeating) we would get:
