Answer:
(32/2)*3=48
Step-by-step explanation:
In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.
Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.
If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
Ahhhhhh tooo muchhhhh workkk

Answer:
The standard normal distribution should be used due to the large sample size ; also also proportions are what is required.
Step-by-step explanation:
Given that:
Sample size, n = 1700
p = 63% = 0.63
Given that the sample size is large at n = 1700 ; the binomial distribution and t - distribution aren't ideal for distributions of such size. Also, we are interested in the population proportion which from the standard normal formula who's interval could be obtained thus :
[p ± Zα/2 * sqrt(p(1 - p))]
Both the t-distributon and binomial distributions are for experiments whith relatively small or low.
V(t)= 5000 - 500t I think
