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:
as x approaches infinity, f(x) approaches 0
as x approaches -infinity, f(x) approaches infinity
Step-by-step explanation:
we can observe that 1/2 < 1 and since it's being exponentiated, the f(x) gets smaller and smaller as x gets bigger.
For example, f(0) = 1, f(1) = 1/2, f(2) = 1/4
so, as x approaches an infinitely large number, f(x) gets closer and closer to zero.
this is the opposite as x approaches a negatively large number. following exponential rules, 1/2^(x) = 2^x for all x < 0. therefore as x approaches negative infinity, f(x) approaches infinity.
in this case, f(-1) = 2, f(2) = 4, f(3) = 8
I believe the answer would be D, 2y+6/9y-7 x 3/2 because dividing by a fraction is the same as multiplying by its reciprocal (the fraction flipped).
Hope I helped! ;)
Answer:
3 1st class tickets and 5 coach tickets
Step-by-step explanation:
1. Subtract 3630 (cost of 3 1st class tickets) from the budget to get 1000.
2. Subtract 1000 (cost of 5 coach tickets) from your remaining budget to get 0.
