The z-score of 30,000 is -2. Reference to a normal standard distribution table shows that 97.72% of tires will have a life of at least 30,000 miles.
Answer:
t = 1.94 seconds
Step-by-step explanation:
we have to solve the following polynomial equation:
-16t² + 60 = 0
16t² = 60
t² = 60/16 = 3.75
t = √3.75 = 1.936491673 seconds
the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option
Green: 2/9×100=22. 22%
Red: 4/9×100=44. 44%
Blue: 3/9×100=33. 33%
Probability: 22. 22%+44. 44%+
33.33%= 99.99%
100. 00-99. 99= 00. 01%

Answer:
0.72 and 18/25
Step-by-step explanation:
1) Address input parameters & values.
Input parameters & values: The decimal number = 0.72
2) Write it as a fraction 0.72/1
3) Multiply 100 to both numerator & denominator
(0.72 x 100)/(1 x 100) = 72/100
It can be written as 72% = 72/100 or 72/100
4) To simplify 72/100 to its lowest terms, find LCM (Least Common Multiple) for 72 & 100. 4 is the LCM for 72 & 100.
5) divide numerator & denominator by 4. 72/100 = (72 / 4) / (100 / 4)= 18/25
6) 18/25 and 0.72.
