Answer:
The definition of a z-score is:
z = (X - μ)/σ where X is our given score (33), μ is the distribution's mean (40) and σ is the distribution's standard deviation (9).
To calculate the z-score for 33, plug the numbers in:
z = (33 - 40)/9 = -7/9 = -.78
Hope this helps!
Step-by-step explanation:
Wassup4, your questions is unsolvable because you said the school made $175 from the box office, yet you just said that the money from adult sales was $188 dollars and 175. But I'll solve it anyway. 175=188+3x. -13=3x x=-4 1/3. Technically, the school lost 4 1/3 students. Don't trust my calculation.

Answer:
45.7 s
Step-by-step explanation:
Darya:
Number of laps = 13
Average time per lap = 23.5 seconds
Total time to swim 13 laps = Number of laps × Average time per lap
= 13 × 23.5
= 305.5 seconds
Kana:
Number of laps = 10
Average time per lap = 25.98 seconds
Total time to swim 10 laps = Number of laps × Average time per lap
= 10 × 25.98
= 259.8 seconds
It took longer for Darya to swim
13 laps than for Kana to swim 10 laps.
How much longer?
= 305.5 seconds - 259.8 seconds
= 45.7 seconds
