A decibel is a unit that measures the loudness of a sound. The larger the number of decibels, the louder the sound. The Occupational Safety and Health Administration (OSHA) has limits of exposure for different sound levels, as seen in the table below: Sound Level Maximum Allowed Duration
(decibels) [left] per Work Day (hours) [right]

90 | 8

92 | 6

95 | 4

100 | 2

105 | 1

110 | 0.5

115 | 0.25

Suppose a manager wants to know how long a worker can be exposed to a sound level of 120 decibels. Find a line of best fit. Describe how well it fits the data and whether it can make a good prediction for the manager.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
