Y + 3 = 2x
y + 4 = 3x
If you use the comparison method to solve the given system, what is the resulting equation?
A)y + 3 = y +4
B)2x - 3 = 3x - 4
C)2x + 3 = 3x + 4

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.
