Answer:
The required probability is 0.9916
Step-by-step explanation:
Consider the provided information.
If 45% of cars are traveling in excess of 70mph,
Therefore, p = 0.45
q = 1-p = 1-0.45 = 0.55
8 random cars are measured via radar: n = 8
We need to find at least 1 car is going over 70mph.
According to binomial distribution:
We need to find P(X≥1)
Hence, the required probability is 0.9916

Answer:
yes
Step-by-step explanation:
What is 8 meters increased by 28%?
Well, first, you need to convert 28% to a decimal by moving the decimal two to the left by dividing by 100
28÷100=.28
or
28%⇒28⇒.28
Then you multiply
8 meters times .28
Then you add 2.24 to 8m (since its the original number)
Your answer is 10.24m
