Answer:
394.8
Step-by-step explanation:
the missing angle is 180 - 26 - 27 = 127
32/sin 27 = x/sin 26, x(side UV) = 30.899053
Area = 1/2ab sin C
1/2 (30.9)(32) sin 127 = 394.8
If I could help I would but I don’t understand how to do it

Step-by-step explanation:
Answer:
The larger sample sizes gives a narrower confidence interval
Step-by-step explanation:
The larger sample sizes gives a narrower confidence interval, that is, a more "precise" estimation of the elections results.
In a confidence interval of proportions, we have that the lower end is given by:
In which is the probability of a sucess, is a value from the Z table and n is the length of the sample.
The upper end is given by:
As n increases, the difference between U and L decreases. This means that the confidence interval gets narrower.
