h. iq of students at a math competition.\ni. salaries of cashier at a bookstore\nj. classification of the students performance as excellent or poor.\nk. gmat score for students entering the graduate school\nproblem 2 (show your work to get credit)\nthe following information shows the computer types in a survey.\na. use the tables information to construct a pie graph (you need first to find the percents and degrees - show your work i.e. write the formula for the degrees and percents and find them)\nb. use the table to construct a pie graph.\n| | number | degrees | percents |\n| ---- | ---- | ---- | ---- |\n| silver | 97 | | |\n| red | 48 | | |\n| black | 117 | | |
Answer
Explanation:
Step1: Calculate total number
$97 + 48+117=262$
Step2: Calculate percent for Silver
Percent of Silver $=\frac{97}{262}\times100%\approx37.02%$ Degree of Silver $=\frac{97}{262}\times360^{\circ}\approx133.28^{\circ}$
Step3: Calculate percent for Red
Percent of Red $=\frac{48}{262}\times100%\approx18.32%$ Degree of Red $=\frac{48}{262}\times360^{\circ}\approx65.95^{\circ}$
Step4: Calculate percent for Black
Percent of Black $=\frac{117}{262}\times100%\approx44.66%$ Degree of Black $=\frac{117}{262}\times360^{\circ}\approx160.77^{\circ}$
Answer:
| Number | Degrees | Percents | |
|---|---|---|---|
| Silver | 97 | $\approx133.28^{\circ}$ | $\approx37.02%$ |
| Red | 48 | $\approx65.95^{\circ}$ | $\approx18.32%$ |
| Black | 117 | $\approx160.77^{\circ}$ | $\approx44.66%$ |
