Answer:
B. No, because the trials of the experiment are not independent and the probability of success differs from trial to trial.
Step-by-step explanation:
The first criterion of a binomial distribution is a fixed number of trials. Selecting 5 senators means the number of trials is 5, which is a fixed number.
The next criterion is that the trials must be independent. Selecting the senators without replacement means the trials are dependent, not independent; this means that this is not a binomial distribution.
Answer:
14/20
Explanation:
Sasha tried to get a marble 20 times. 14 of those times she got a yellow marble.
The experimental probability, which is the probability of choosing a yellow marble when Sasha actually tries choosing marbles from the bag.
The theoretical probability is based on the chance that Sasha will get a yellow marble, 7/70, is from the amount of marbles in the bag of yellow colour.
1/4 (8 + 6z + 12)
------------------------------------------------------------
Combine like terms :
------------------------------------------------------------
1/4 (6z + 20)
------------------------------------------------------------
Apply distributive property :
------------------------------------------------------------
1/4(6z) + 1/4(20)
3/2z + 5
------------------------------------------------------------
Answer: 3/2z + 5

Help with what part I can help
Answer:
B. 15c > 1,800 + 10c
Step-by-step explanation:
Profit=Total revenue - total cost
Profit is achieved:
when total revenue is greater than total cost
TR>TC
Or
When total cost is less than total revenue
TC<TR
From the question
Total cost=1800+10c
Total revenue=15c
Profit=TR>TC or TC<TR
15c>1800+10c
Or
1800+10c<15c
Option B. 15c > 1,800 + 10c satisfies the condition that Profit=TR>TC
