Answer:
The number of adult tickets sold was 121
Step-by-step explanation:
The general equation is: <em>S</em> + <em>A</em> = <em>T</em> ;where <em>S</em> means student tickets, <em>A</em> means adult tickets and <em>T</em> means total tickets. We know that <em>S</em> is two times <em>A</em> and <em>T</em> is 363. So, <em>S</em> will be 2x and A will be x. Then, the new equation is 2x + x = 363.
<em>S</em> + <em>A</em> = <em>T</em>
2x + x = 363
3x = 363
x = 363 / 3
x = 121
Adult tickets: <em>A</em> = x = 121
Student tickets: <em>S</em> = 2x = 2 * 121 = 242
Answer:
Lowest acceptable score = 121.3
Step-by-step explanation:
Mean test score (μ) = 115
Standard deviation (σ) = 12
The z-score for any given test score 'X' is defined as:
In this situation, the organization is looking for people who scored in the upper 30% range, that is, people at or above the 70-th percentile of the normally distributed scores. At the 70-th percentile, the corresponding z-score is 0.525 (obtained from a z-score table). The minimum score, X, that would enable a candidate to apply for membership is:
