Answer:

b. The number of digits in a randomly selected row until a 3 is found.

Explanation:

A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.

In statistics and probability, random variables are either continuous or discrete.

1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.

2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.

Also, any random variable that meets certain conditions defined in a research study.

Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.

Everyone (has, have)______already voted in the election.

"Has" would make more sense. A tip would be to read the sentence with both words, one word at a time obviously (So Everyone HAS already voted in the election.) and just go with your gut on which one makes more sense, you can do it!

A precaution for heat transfer lab

Schach [20]

Answer:

Safety precautions in the heat transfer laboratory depend on the equipment that you will use.

Explanation:

The safety measures or precautions that an experimenter needs to bear in mind depends on the types of equipment he/she's using in experimenting. But, there are general precautions to consider.

There are three different ways to transfer heat, including convection, conduction, and radiation. Convection pertains to the heat transfer between liquid or gas molecules moving circularly. Through that, their temperature and density are both affected. Conduction and radiation are polarities. The heat transfer happened when two objects touched one another in conduction. On the other hand, radiation occurs when two objects do not touch each other.

Generally, precautions in performing these three experiments include the following:

Careful handling of glassware to avoid cracking or breaking it.
Avoid spilling the liquid or any content of the glassware.
Do not touch any hot object.
Use a hot pad to transfer hot objects from different places.
