Answer:
see image
Step-by-step explanation:
put the points from the table on the graph. Like time is the x and drinks is the y. These are the variables: time and number of drinks. Go over to 11, then up to 20, put a point there, etc. Do this for all five pairs of the numbers in the table. Imagine a line that goes thru the data points. See image. It is a pretty good line for the data. The points come pretty close to the line, where they miss is sort of random and on both sides of the line. This is a good thing. The line goes up, so the correlation is positive. When the line is a good line the correlation coefficient, r is 1 or -1. A bad line that doesn't match the data is smaller decimals like the .5 or -.5
Here its good and positive, so r=1

<h3>What is meant by percentage?</h3>A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.
<h3>How many pears did the Type B trees produce?</h3>- Type A trees produced 20 percent more pears than Type B trees did
- Type A trees produced 144 pears.
Let us consider, Type B produced 100% pears.
So, Type A will produce 120%of B, that is 144
144 = 120/100 B
simplifying the above equation, we get
144 100 = 120B
B = 14400/120
B = 120
The value of B = 120.
Hence, the Type B trees produces 120 pears
Therefore, the correct answer is option B) 120.
