Which polynomial function has a leading coefficient of 2, root-4 with multiplicity 3, and root 10 with multiplicity 1? Of(x) = 2(x - 4)(x - 4)(x – 4)(x + 10)
Of(x) = 2(x + 4)(x + 4)(x + 4)(x - 10)
Of(x) = 3(x - 4)(x - 4)(x + 10)
f(x) = 3(x + 4)(x + 4)(x - 10)

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.
