Answer:
92 dB
Step-by-step explanation:
Use the mean formula, mean = sum of elements / number of elements.
Since it is a 8 hour work day, there are 8 elements.
mean = sum of elements / number of elements
mean = (98 + 98 + 98 + 98 + 98 + 82 + 82 + 82) / 8
mean = 736 / 8
mean = 92
So, the average noise level is 92 dB
Furthest from 0, so I am going to take the absolute value of these numbers. The absolute value will tell us how far away from 0 these numbers are.
|-1/2| = |- 0.5| = 0.5
|8/9| = |0.88| = 0.88
|0.2| = 0.2
so the number furthest from 0 is 8/9
Multiply the amount of seconds to ring up items by the amount of items.
1 × 17 = 17
Now add the amount of seconds to process a payment to the product.
17 + 25 = 42
<h2>Answer:</h2>
<u>It takes </u><u>42 seconds</u><u> to ring up a customer with 17 items.</u>
