Trisha needs to make at least 50 gift bags for an event. Each gift bag will contain at least 1 thumb drive or key chain. She wants to use at least 5 times as many key chains as thumb drives. She has 25 thumb drives and 200 key chains. Let x represent the number of key chains. Let y represent the number of thumb drives.

Which inequalities are among the constraints for this situation?

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.
