Answer:
If all the 300 students were surveyed, 220 would have been in favor of the photo booth.
Step-by-step explanation:
Sample size = 15
People out of 15 in favor of photo booth = 11
Percentage of people in favor of school dance =
We have to find if all 300 students are surveyed how many will be in favor of photo booth. Remember that, the sample data is the best estimator of the population data. So, the sample data of 15 students will be the best estimator for the entire population of 300 students.
Since, in the sample of 15 students, were in favor of photo booth, we would expect that if all the 300 students were surveyed, the same percentage will be in favor of photo booth. So we need to calculate of 300.
This means if all the 300 students were surveyed, 220 would have been in favor of the photo booth as per the sample data.

Answer:
Probability that point chosen is in large circle but not in shaded region:
P = 84%
Step-by-step explanation:
Given that
r = 2 inches
R = 5 inches
<h3>Area of Small circle (shaded region):</h3>
<h3>Area of Large circle:</h3><h3>
</h3><h3>Probability of Point being chosen is inside shaded region:</h3><h3>
</h3><h3>Probability of Point being chosen is NOT inside shaded region:</h3>
P = 100% - 16%
P = 84%
