Answer:
a) C. The random variable is discrete. The possible values are xequals0, 1, 2,....
b) B. The random variable is continuous. The possible values are x greater than or equals 0.
Step-by-step explanation:
Discrete variables are countable in a finite amount of time. Continuous variables can be infinitely many. They rather assume values in a range.

Answer:
The discriminant of the quadratic equation is -7.
Step-by-step explanation:
We are given the following quadratic equation in the question:
Comparing to general quadratic equation:
We have to find the discriminant of the quadratic equation.
Formula:
Putting values, we get,
Thus, the discriminant of the quadratic equation is -7.
I believe that is c if I'm wrong I'm very sorry
first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
