Can someone me answer this?
given the function f(x)= x^2+7x+10 / x^2+9x+20
describe where the function has a hole and how you found your answer.

we need to simplify the function by factoring the numerator and the denominator. plug the excluded values into the simplified function to find the hole.

The function f(x) has a hole at point x = - 5.

Step-by-step explanation:

We are given a function as

Now, we have to describe where the function has a hole.

Now,

⇒

Therefore, the common factor of the numerator and denominator is (x + 5).

Now, (x + 5) = 0

⇒ x = - 5

Therefore, the function f(x) has a hole at point x = - 5. (Answer)

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.
