Answer:
605 pounds/hour
Step-by-step explanation:
Given that a coffee bean processor can dry 4815 pounds of coffee in 3 hours.
We have to find the speed of the processor
By speed of the processor here we mean the unit rate i.e. no of pounds of coffee beans that the processor can process in one hour.
This is a question of direct variation
Since we have for 3 hours 4815
for 1 hour = pounds/hour
So answer is 605 pounds/hour
Verify:
If unit rate is 605 pounds/hour, for 3 hours =605(3) = 4815 pounds
Thus verified

Answer:
The value that is greater than 45% of the data values is approximately 137.84.
Step-by-step explanation:
The key is transforming values from this distribution to a z-score range and finding the corresponding value using a z-score table.
We are looking for a value x which attains a critical z-score that corresponds to the (100-45)%=55-th percentile:
The critical z value (from z-score table, online) is: -0.12, so:
The value that is greater than 45% of the data values is approximately 137.84.
