The admission to a local carnival is $6.50 per person and $2.50 for each ride. jenna wants to know much it will cost her to ride a certain number of rides at the carnival. which equation can she use to create a table with this information (where  p  is the number of persons,  r  is the number of rides, and  t  is the total cost of admission and rides)?   6.50p  + 2.50 =  t6.50 + 2.50r  =  t6.50r  + 2.50 =  t6.50 + 2.50p  =  t

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.
