Explain whether a bar graph, double bar graph, or circle graph is the best way to display the following set of data: the number of teens who attended art museums, symphony concerts, rock concerts, and athletic events in 1990 compared to the number who attended the same events this year. a. circle graph b. bar graph c. double bar graph d. none of them

Bar graphs are used to compare things between different groups or to track changes over time.

Double bar graphs , help us to compare more than one kind of situations, or events instead of just one by using bars.

A circle graph, shows the relationship between the whole circle and the various slices that represent portions of that circle.

The number of teens who attended art museums, symphony concerts, rock concerts, and athletic events in 1990 compared to the number who attended the same events this year can be best represented by option c. double bar graph.

C: Double Bar Graph

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
