Question
The table shows the maximum depth, in meters, of the 5 deepest oceanic trenches.
What is the range, in meters, of these 5 trench depths?
- 151
- 533
- 835
- 986
The correct answer is: 986
Range of a dataset = maximum value in the dataset - minimum value in the dataset
Explanations:
Step 1 of 2:
In the given table, the Kermadec Trench has the minimum depth (meters), viz. 10047.
Minimum value in the dataset = 10047
And the Mariana Trench has the maximum depth (meters), viz. 11033.
Maximum value in the dataset = 11033
Step 2 of 2:
The range, in meters, of these 5 trench depths is given by,
Range = 11033 – 10047 = 986
Final Answer:
The right option is — 986.

For a certain group of fish, the graph models the relationship between body length L, in centimeters (cm), and tail area A, in square centimeters , where . Which equation represents the relationship between body length and tail area?
Solving quadratic equations using a graph is an effective method for locating estimated solutions or roots for quadratic equations or functions.
The real roots of a quadratic function might be zero, one (repeated), or two. Finding the origins involves solving a quadratic equation with the right-hand side equal to zero, such as ax² + bx + c = 0.
Points to consider to solve a quadratic equation using a graph :
• Rearrange the equation so that one side corresponds to the graphed function.
• Plot the function y= the other side of the equation.
• To find the solutions, draw vertical lines down to the x-axis from the intersection points.
