Use the information in the table. You are making a circle graph showing the total number of successful United States space launches. What is the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989?

Step-by-step explanation:

step 1

we know that

The total number of successful United States space launches that happened in the years 1957-1995 is equal to

step 2

The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

step 3

The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

step 4

Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches  that happened in the years 1980-1989

we know that

In a circle, 360 degrees represent the 100%

so

using proportion

Find out the measure of the central angle by a percentage of 14.68%

Academic grading in the United States commonly takes on the form of five, six or seven letter grades. Traditionally, the grades are A+, A, A−; B+, B, B−; C+, C, C−; D+, D, D−; F; with A+ being the highest and F being lowest. Numeric to letter grade conversions generally vary from system to system and between disciplines and status. In some cases, grades can also be numerical.
