Sharks and orcas hare a lot in common. Both of these sea animals are carnivores (meat-eaters) that hurt for their food. Like sharks, orcas have smooth bodies that can speed through the water, and lots of sharp teeth. But these is are major difference sharks are wish, while orcas are mammals! Like most fish, sharks by lay eggs: But orca babies are born live and drink milk from their mothers. Another difference is that orcas have Sony skeletons, but sharks have no bones at all-only casttly.

Consider this simple bivariate data set
a) Draw a scatter plot for the data
b) Describe the correlation between x and y as positive or negative.
c) Describe the correlation between x and y as strong or weak.
d) Identify any outliers.

At what percent of simple interest will the sum of money amount to 5/3 of itself in 6 years 8 months?

Show the conjecture is false by finding a counterexample. Two adjacent angles always form a linear pair.

For each of the following sets of bivariate data with variables x and y:
Draw a scatter plot by hand. Decide whether y generally increases or decreases as x increases.

If the two variables increase and decrease together, then they are directly proportional and have a positive slope.

Explain why the drawn line of best fit is accurate or why not.
This scatter plot shows the amount copper in water in ppm versus plant growth in cm over three months.

Show the conjecture is false by finding a counterexample. If AB ≅ BC, then point B is the midpoint of AB.

Construct a scatter plot for the following data set using appropriate scale for both the X and Y axis.
This table shows the age of students and their scores on the MAP test.

We usually take the independent variable on the x- axis and the dependent variable on the y-axis. A graph could be drawn in different ways using different scales and intervals.

Show the conjecture is false by finding a counterexample. If the product of two numbers is even, then the two numbers must be even.

Use the given data to answer the questions and construct the scatter plots

a) Which variable should be the independent variable (x-axis) and which should be the dependent variable (y-axis)?
b) Construct the scatter plot.

If the sum of money becomes Rs. 3540 in 3 years at the simple interest rate of 6%, what was the sum of money?

Show the conjecture is false by finding a counterexample. If a + b = 0, then a = b = 0.
