The senior class from puma high school raised funds for an end of the year party at club sizzle. it cost $4,000 to rent out club sizzle plus $20 per student for food and drinks. if the senior class raised $11,000, how many students can attend the end of the year party?

both equations and proportions are better.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
