Answer with explanation:
Given : The heights of a certain population of corn plants follow a normal distribution with mean
and standard deviation 
a) Using formula
, the z-value corresponds to x= 135 will be

At x= 155, 
The probability that plants are between 135 and 155 cm tall :-

Hence, 34.73% of the plants are between 135 and 155 cm tall.
b) Sample size : n= 16
Using formula
, the z-value corresponds to x= 135 will be

At x= 155, 
The probability that plants are between 135 and 155 cm tall :-

Hence,The percentage of the samples would the sample mean height be between 135 and 155 cm.= 93.12%
Make it so that the fractions have common denominators. 12 is a common denominator we can use.
5/6= 10/12 1/4= 3/12
Multiply both numbers by 2. Multiply both by 3.
Now, add.
4 10/12+ 5 3/12= 9 13/12
Simplify.
10 1/12.
I hope this helps!

Answer:
okay easy peasy..
first we know that 1 inch represent 50 miles
therefore 550 miles is represented by
= 550/50 = 11 inch
so with this we know that on map the cities are 11 inch apart..
