2(x+b) = ax + c
in the equation above, a, b, and c are constants.
if the equation has infinitely many solutions, what is the solution?

Step-by-step explanation:

2(x + b) = ax + c

2x + 2b = ax + c

2x - ax = c - 2b

x(2 - a) = (c - 2b)

x = (c - 2b)/(2 - a)

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.
