<h3>What is a mathematical expression ?</h3>
In mathematics, an expression or mathematical expression is a finite combination of symbols well formed according to context-dependent rules. Mathematical symbols can be used to define numbers (constants), variables, operators, functions, parentheses, punctuation marks, and groupings that help define the order of operations and other aspects of logical syntax.
Many authors distinguish between an expression and a formula, the first meaning a mathematical object and the second a statement about mathematical objects.

Answer: 0.0228
Step-by-step explanation:
Given : The mean and the standard deviation of finish times (in minutes) for this event are respectively as :-
If the distribution of finish times is approximately bell-shaped and symmetric, then it must be normally distributed.
Let X be the random variable that represents the finish times for this event.
z score : 
Now, the probability of runners who finish in under 19 minutes by using standard normal distribution table :-
Hence, the approximate proportion of runners who finish in under 19 minutes = 0.0228
3 1/8 means 8 x 3 + 1 = 25/8
Step-by-step explanation:
4/5 x 25/8
= 4x25/5x 8
= 100/40
= 5/2
