What are the key features of the equation y = (x + 12)(x + 6)? The x-intercepts are (-12, 0) and (-6, 0). The y-intercept is (0, 72). The vertex is
an absolute maximum, (-9, -9).
The x-intercepts are (12, 0) and (6, 0). The y-intercept is (0, 72). The vertex is an
absolute minimum, (-9, -9).

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.
