Which of the following is/are NOT correct about a continuous random variable? CHECK ALL THAT APPLY. A. It can only take on integer values. B. The probability that it has a value equal to x is given by f(x) where f is the density function. C. The probability that it has a value that falls between real values a and b is given by the area under the density function over the range (a, b).

a

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.
