Qualitative 15. x is the time it takes a chef to cook a specific dish, is a continuous random variable. Why do think the variable x in the statement becomes continuous? A. The variable x is continuous because it takes a range of values B. The variable x is continuous because it takes an integral values. 14What I Have Learned Give your answer in the following statements. 1. A well - defined function from a sample space to the set of real numbers is called a . It is commonly denoted by capital letters, such as X, Y and Z. The specific values of a random variable is denoted by small letters such as x, y, and z. 2. A random variable is a if its set of possible outcomes is countable. Mostly, discrete random variable represents count data, such as the number of enrolled students in a particular school. 3. A random variable is if it takes on values on a continuous scale. Often, continuous random variables represent measured data, such as heights, weights temperatures and lifespan.Additional Activities Answer the following.x Identify whether the given experiment involves a discrete random variable or a continuous random variable. Write D if discrete and C if continuous. 1. Getting the distance travelled by a car 2. Collecting data about the weights of students in a certain school 3. The temperature in Quezon at noon times 4. Picking a multiple of 3 less than 200 5. Tallying the number of PUI (Person Under Investigation) due to Covid-19 pandemic
