Answer:
You can tell that quantities x and y are proportional if they are effecting each other.
Step-by-step explanation:
If two quantities are proportional that means they are dependent on each other.
- The quantities can be directly proportional and inversely proportional as well.
- If the increase in one quantity will increase the other quantity and decrease in quantity leads to the decrease in other then it is directly proportional. Like in Ohm's Law: the current and voltage are directly proportional in linear circuit while neglecting the resistance. The following expression show this direct proportional relation:
V ∝ I
- If the increase in one quantity results in the decrease of the other quantity or vice versa then these quantities are inversely proportional. Like if the people required to do a job increases then time required to complete the job will decrease or vice versa.
Answer:
1. Scatter plots are used to observe relationships between variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.
2. A Scatter Analysis is used when you need to compare two data sets against each other to see if there is a relationship. Scatter plots are a way of visualizing the relationship; by plotting the data points you get a scattering of points on a graph

Answer:
48.983.
Step-by-step explanation:
(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).
Using order of operations (PEMDAS):
20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:
= 20.003 + [35.85 - 6.87] Now the outer parentheses:
= 20.003 + 28.98
= 48.983.
