Find the mean number of minutes on social media.

34056747575380135476

15.5

Step-by-step explanation:

to find the mean you need to add up the number of minutes on social media. This would add up to 93.

step one: add up the number of minutes, which we know equals 93.

step two: Add up the amount of people on the chart. Six people were apart of the chart for number of minutes on social media. These people were Vera, Timothy, Manuela, Khaled, Yash, and Fernanda. (Even though Timothy has no minutes, you still count him.)

step three: Since there are six people, you divide the amount of people by the amount of minutes. (six divided by 93)

Six divided by 93 = 15.5

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
