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
Answer:
area = 160160 inches²
area = 1.6016 × 10⁵ inches²
Step-by-step explanation:
The length of the rectangular computer chip is 22 × 10 cm and the width is 7 × 104 cm .
The area of the rectangular computer chip is the product of the length and the width.
area = length × width
area = (22 × 10) × (7 × 104)
area = 220 × 728
area = 160160 inches²
In scientific notation
area = 1.6016 × 10⁵ inches²
160160 is written as 1.6016 × 10⁵ because 1.60160 × 100000 = 1.6016 × 10⁵
