The table is a little strange because the rows don't add to 100% and the colums don't add to give their "total." Thus, it is not real clear exactly what the table is trying to tell us.
We assume we can figure the desired probability (chicken sandwich is tops given that a non-veggie sandwich is tops) by adding the non-vegetable numbers for a town and dividing that into the number for chicken sandwiches. This is what we have done in the attached spreadsheet. The result is that the desired ordering appears to be ...
Town 1 ⇒ Town 4 ⇒ Town 2 ⇒ Town 3

Answer:
The proportion of students whose height are lower than Darnell's height is 71.57%
Step-by-step explanation:
The complete question is:
A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 centimeters. Darnel is a middle school student with a height of 161.4cm.
What proportion of proportion of students height are lower than Darnell's height.
Answer:
We first calculate the z-score corresponding to Darnell's height using:
We substitute x=161.4 , , and
to get:
From the normal distribution table, we read 0.5 under 7.
The corresponding area is 0.7157
Therefore the proportion of students whose height are lower than Darnell's height is 71.57%
Answer:
1½ cords per hour
Step-by-step explanation:
A log splitter can split 6/5 cords of wood in 4/5 of an hour.
To find a unit rate, we divide the quantity of cords of wood by the time.
This gives us the complex fraction.
This is the same as
To divide two fractions, we multiply by the reciprocal of the second fraction.
This simplifies to:
The unit rate is 1.5 cords per hour
