How many solutions does the following system have?
y= 5x + 8
y = 5x + 3

This system has no solutions.

Step-by-step explanation:

If we try to solve:

Since there are no x values left over and the remaining solution is zero, there is no solution for this equation.

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.
