a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
Step-by-step explanation:
Given,
Price of one adult ticket = a = $25
Price of one youth ticket = y = $12.50
Maximum people that can be hold by theater = 1000
Therefore;
The maximum number of people can be 1000 or less than that.
As they want to revenue to be more than 15,000 therefore,
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

Answer
given,
the standard deviation:-
of the students height in the class = 4.2 inches
of the male heights in the class = 3.4 inches
of females height in the class = 3.3 inches
standard deviation is the deviation of the value from the target value.
the given question standard deviation of the students is more than that of the individual standard deviation of the heights of males and females because of the distribution of the entire class has more dispersion.
