Y=2 x=3 double check is at bottom but cut off
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
The answer to this is negative
Answer:
x = 8
y = 16
Step-by-step explanation:
8 + 8 = 16
y = 16
