What requirements must be satisfied? select all that apply. a. at least one observation must be above or below 9090 sec. b. either the population is normally distributed, or ngreater than> 30, or both. c. the sample observations must be a simple random sample. d. the conditions for a binomial distribution must be satisfied?

In order to satisfy the requirement, this are the following that is required;First, at least one observation must be above or below 90 seconds. Second is ether the population is normally distributted or greater than (>) 30, or maybe both.
The answer in this question is A and B.

Based on how the triangle looks and the directions given, you know that this is a right triangle.

You can use the Pythagorean Theorem, which is a^2 + b^2 = c^2, with c being the hypotenuse. If you plug in the values, you get

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

√100 = √c^2

c = 10

This means that Robert traveled 10 kilometers on the way back home, HOWEVER, it asks for the round trip distance. He traveled 14 km on the way there and 10 km on the way back, which means the round trip distance is 24 km.

I hope this makes sense!
