“Line graphs are useful in that they show data variables and trends very clearly and can help to make predictions about the results of data not yet recorded. They can also be used to display several dependent variables against one independent variable.”
“With a line graph, it is fairly easy to make predictions because line graphs show changes over a period of time. You can look at past performance in a line graph and make a prediction about future performance.”

Answer:
Step-by-step explanation:
The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.
a² = 7² -4²
a² = 49 -16 = 33
a = √33
Answer:
B
Step-by-step explanation:
The arc XZ is twice the measure of the inscribed angle XYZ , that is
arc XZ = 2 × 60° = 120°
The complete circumference = 360° , thus
arc XYZ = 360° - arc XZ = 360° - 120° = 240° → B
