<span>A: The middle 95% contain between 23.8 and 24.2 oz.(2 SDs under and over the mean)
B: Approximately 68% of boxes have between 23.9 and 24.1 oz of cereal (1 SD under and over the mean)
C: 2.5% of boxes contain more than 24.2, because 95% are within 2 SDs, and that includes lower and higher extremes.
D: 16% of boxes have more than 24.1, because 68% are within 1 SD of the mean, so 32 are left, and that includes lower and higher extremes.</span>

Answer:
Step-by-step explanation:
We require to create 2 equations with the repeating digit (6) after the decimal point.
let x = 0.166.... ( multiply both sides by 10 and 100 )
10x = 1.66.... → (1)
100x = 16.66..... → (2)
Subtract (1) from (2) eliminating the repeating decimal
90x = 15 ( divide both sides by 90 )
x = =
Thus
0.166...... =
