Move 8x to the right
0=x^2-8x+15
Then factor
(x-5)(x-3)
Final answer: C
Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:

there are 7 verticles on this triangular prism
The answer is 30 because
3/10 × 9/x = 30 .
