Answer:
b. A binomial variable with 25 independent trials
Step-by-step explanation:
The conducted experiment is binomial experiment because outcome can be divided into success or failure. The success would be the people who read novel in the past year and also responses are independent of each other. We have to find the number of trials n in the given problem.
we are given that variance of R=6 and p=probability of success=0.4.
We know that variance of binomial distribution is
Variance=npq
where q=1-p=1-0.4=0.6.
By putting the values in variance formula, we can get the value of n.
6=n*0.4*0.6
6=0.24*n
n=6/0.24
n=25
Hence, random variable R is a binomial variable with 25 independent trials.
Answer:
f = 8
Step-by-step explanation:
- Apply the distributed property, so it now looks like this: 2f - 10 = 6
- Add 10 to each side, so it now looks like this: 2f = 16
- Divide each side by 2 to cancel out the 2 next to f. It should now look like this: f = 8
I hope this helps!
Answer:
sorry
Step-by-step explanation:
plz send full question
The angles of a triangle always add up to 180°.
By simply adding the angles and checking the total, you can tell if they make a triangle or not.
Using this property, 5 won't make a triangle, 6 will.
Hope this helps! :D
