Answer:
You need $7.09
Step-by-step explanation:
Ex1. 100-92.91=7.09
Ex2. 92.91+7.09=100
2/3= 0.6
3.06 would be the answer I believe.
Hope this Helps!!
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
X+(3/3)=y+(2/2)
x+1=y+1
x=y
x/3=y/3
Answer: x/3=y/3
