Compute the limit of the following as x approaches infinity.

after multiplying both sides by the conjugate, i got the limit 1/∞ after plugging in the limit, but is that the proper answer? 1/∞ would just make the answer 0, right?

Yes, that's the correct limit.

, but since , we are considering , for which . Then

and both and vanish as , making the overall limit 0.

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.
