Determine whether the random variable is discrete or continuous. a. The time it takes to fly from City Upper A to City Upper B. b. The time it takes for a light bulb to burn out. c. The number of fish caught during a fishing tournament. d. The number of textbook authors now sitting at a computer. e. The distance a baseball travels in the air after being hit. a. Is the time it takes to fly from City Upper A to City Upper B discrete or continuous? A. The random variable is discrete. B. The random variable is continuous.

a. Continuous random variable

b. Continuous random variable

c. Discrete random variable  

d. Discrete random variable

e. Continuous random variable  

a.The time it takes to fly from City Upper A to City Upper B is a continuous random variable.

Step-by-step explanation:

In (c) and (d), the values of the variables can be found by counting. The number of fish and the number of textbook authors can be counted. Hence, they are discrete random variable.

In (a), (b) and (e) the values can be found by measuring. The time taken to fly, the time taken for light to travel and the distance to travel are the variable that are measured. Hence, they are continuous random variable.

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
