Answer:
The probability that exactly 5 are unable to complete the race is 0.1047
Step-by-step explanation:
We are given that 25% of all who enters a race do not complete.
30 have entered.
what is the probability that exactly 5 are unable to complete the race?
So, We will use binomial
Formula : 
p is the probability of success i.e. 25% = 0.25
q is the probability of failure = 1- p = 1-0.25 = 0.75
We are supposed to find the probability that exactly 5 are unable to complete the race
n = 30
r = 5
Hence the probability that exactly 5 are unable to complete the race is 0.1047
5=-7s
5/-7

Answer: Your question is missing information but this is what you do to answer your question step by step
B = Cost of 8 pack / 8 bottles = $ Cost of 8 pack/ 8 =$ ____ per bottle
A = Cost of 6 pack/ 6 bottles = $ Cost of 6 pack/ 6= $ ____ per bottle
then do a simple subtraction A -B = savings
Step-by-step explanation: Information is incomplete
if an 8 pack cost $16
If the 6 pack cost $15
All you do is a simple subtraction after calculations
Cost of 8 pack / 8 bottles = $16/8 =$2 per bottle
Cost of 6 pack/ 6 bottles = $15/ 6= $2.50 per bottle
in my example
You would save $ 0.50 per bottle by purchasing the 8 pack
Answer:
Unreduced: (4) + (5 • x) + (-9) + (4 • x)
