Luca solved an equation as shown , and verified that his solution was correct . sqrt(2x - 5) = sqrt(x - 3) + 1 1 (sqrt(2x - 5)) ^ 2 = (sqrt(x - 3) + 1) ^ 2 1 2x - 5 = x - 3 + 1 x = 3 Explain what Luca's error is and why his answer is not completely correct .

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.
