Place a check mark in the appropriate box to show whether there is no solution, exactly 1 solution, or if there are an infinite number of solutions for each of the systems shown below. Along with the check mark, explain your reasoning, being sure to discuss
what the graphs of each system would look like.
No solution
Exactly 1 solution
Infinitely many solutions
1.) y = 4x + 2
y = 4x + 3
2.) 2y = -x + 6
y=1/2x+3
3.) y = 6x + 2
y = 4x + 2

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.
