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
2/4+2/4 or 1/2+1/2
if there is 2/4 in one pan and 1/2 in another 2/4=1/2
Answer:
s(r(4)) = 13
Step-by-step explanation:
Substitute and calculate:
s(r(4)) = 13
