Determine what types of solutions the below function has, and explain how you got your answer. 4x^2 -11x+2

Well, following PEMDAS exponets would go first here.

So we already have x^2=x*x

Now x*x*4= x^2*4

now we have x^2*4-11x

11x= 11*x

x^2*4-11*x+2

idk if this would be right but hope this helps if wrong plz correct me and if i am right than plz mark brainliest

Step-by-step explanation:

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.
