Step-by-step explanation:

Step 1: Define Systems

4x + 3y = 37

y = x - 4

Step 2: Solve for x

Substitution

Substitute in y: 4x + 3(x - 4) = 37Distribute 3: 4x + 3x - 12 = 37Combine like terms: 7x - 12 = 37[APE] Add 12 on both sides: 7x = 49[DPE] Divide 7 on both sides: x = 7

Step 3: Solve for y

Define equation: y = x - 4Substitute in x: y = 7 - 4Subtract: y = 3

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.
