Is the number of free dash throw attempts before the first shot is madea discrete random variable, a continuous random variable, or not a random variable? a. it is a discrete random variable. b. it is a continuous random variable. c. it is not a random variable.

a)Discrete random variable

Step-by-step explanation:

A discrete random variable is a variable which can only take a countable number of values, it means only take values in the natural numbers.

A continuous random variable is a random variable where the data can take infinitely many values; the random variable take values in the real numbers

Then the number of free throw attempts before the first shot is a discrete random variable because these can be counted with the natural numbers.

a)Discrete random variable

Step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
