Answer and explanation:
Discrete random variables can be counted as integers and you can't divide them. Continuous random variables are counted as real numbers and are magnitudes that can´t be counted as an exact number (there will always be an uncertainty in the measurement).
a. The random variable is continuous. Distance is a measurement.
b. The random variable is discrete. You can count how many people are sitting at a computer.
c. The random variable is continuous. Weight is a measurement.

Answer:
2
Step-by-step explanation:
7x4-3x8+2^2-6 : you have to do exponents 1st
7x4-3x8+4-6 : next you multiply 7x4 and -3×8
28-24+4-6 : you add -24+4
28-20-6 : you subtract 28-20
8-6 : you subtract 8-6
2 : thats your answer
