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
22 total tokens
15/22 is the probability you won’t draw a red
uhm i think its 15 cause you just add them all i guess
Your 3/5 - (1/3)x is an expression, not an equation. You must write out the entire equation in question:
"Identify the slope and y-int. of y = 3/5 - (1/3)x."
The y-intercept is obvious: It's 3/5.
The slope is (1/3).
756 is your answer Hope this helps
