Variable is a letter next to a number whether it’s x or y it can be any letter really but main ones is x and y and data is something written down from an oberservartion whether it’s an experiment or table etc.
Answer:
9.8 m/s/s
Explanation:
The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/s2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling at 9.8 m/s.

Probability distributions are used to represent data and their probabilities
The table entry is given as:
<u>Age of House Number of Houses</u>
1 15
2 20
3 25
4 30
Start by calculating the probability of selecting a house that has a certain age.
This is calculated as:
So, we have:
This means that the graph that represents the probability distribution must show that the probability of 1 is 0.17; 2 is 0.22; 3 is 0.28; 4 is 0.33.
