Answer:
Length = 5
Step-by-step explanation:
width = 2
length =5
because 5 x 2 is 10. area is length times width
The expected count of visits is the mean or average visits to each feeder
The expected count of visits to the third feeder is 87.5
<h3>How to determine the expected count of visit?</h3>
The table of values is given as:
Feeder 1 2 3 4
Observed visits 80 90 92 88
In this case, the null hypothesis implies that the visits to each feeder are uniformly distributed
So, the expected count is calculated using:
Expected count =Visits/Feeders
This gives
Expected count = 350/4
Evaluate the quotient
Expected count = 87.50
Hence, the expected count of visits to the third feeder is 87.5

You need to add 1 and 5 and get 6
do 150 divided by 6
you get 25
(y x .12) x .3 = the total cost
