That is true i do believe
Answer:
0.47 is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year
Step-by-step explanation:
We are given the following information:
We treat training as a success.
P(Rain) = 30% = 0.30
Then the chances of rain on each day follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 5
We have to evaluate:
0.47 is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year
Answer:
Investigation 7 introduces a method for computing the ... at a constant rate with respect to the measure of another, then the changes in the ... –5.2 = –3.1∆x ... y = 3.6 + (5.1/–3.5)(x – 12.2) or y = –1.5 + (5.1/–3.5)(x – 8.7).
Answer:
c. 8.25
Step-by-step explanation:
The given scenario corresponds to binomial experiment because
1. There are two possible outcomes i.e. each number can be working or not working.
2. On each dialing the probability of getting working cell number is p=0.55.
3. Cell phone numbers are randomly dialed so these are independent.
4. A pollster dialed 15 cell numbers i.e. n=15.
The mean number of calls that reach a working cell number can be calculated by computing mean of binomial distribution using the given information.
Mean of binomial distribution=E(x)=np
The mean number of calls that reach a working cell number=15*0.55=8.25
Thus, the mean number of calls that reach a working cell number=8.25
