1.2 because the 10th place is the first place after the decimal
Answer:
0.1512 = 15.12% probability that fewer than four tornadoes occur in a three-week period.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
In a given region, the number of tornadoes in a one-week period is modeled by a Poisson distribution with mean 2
Three weeks, so
Calculate the probability that fewer than four tornadoes occur in a three-week period.
This is:
In which
Then
0.1512 = 15.12% probability that fewer than four tornadoes occur in a three-week period.
Answer: 9 remainder 2
Explanation: 9 is the closest 6 can get to 56 without going over. Since 9•6=54, and 56-54=2 , 2 is the remainder.
1/4 is equal to 2/8.
2/8+1/8=3/8
Carla used 3/8 of the ribbon in all. So, 5/8 of the ribbon is left.
I hope this helps :)
