Answer: continuous random variable.

Step-by-step explanation:

A discrete random variable is defined as a random variable which consists of countable number. Examples include numbers of shoes, number of sales etc.

A continuous random variable is a random variable whereby the data can take several values. It is a random variable that takes time into consideration.

Therefore, the amount of time six randomly selected volleyball players play during a game will be a continuous random variable since time so involved.

Composite functions<br> g(d) = 2d - 5 <br> h(d) = -4d +3<br> Find (hºg)(d)

hoa [83]

Answer:

$(h\circ g)(d)=-8d +23$

Step-by-step explanation:

<u>Composite Function</u>

Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:

$(h\circ g)(d)=h(g(x))$

For practical purposes, it can be found by substituting g into h.

The functions g and h are given as:

$g(d) = 2d - 5$

$h(d) = -4d +3$

Substituting g into h:

$(h\circ g)(d)=-4(2d - 5) +3$

Operating:

$(h\circ g)(d)=-8d +20 +3$

$\boxed{(h\circ g)(d)=-8d +23}$
