Eva conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 3 hours. What does this range say about the data? The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
All the students surveyed spend exactly 3 hours surfing the Internet.
All the students surveyed spend an average of 3 hours surfing the Internet.

oh oh 59

Step-by-step explanation:

B

Step-by-step explanation:

If the range is 3 hours, that means that the data points could vary from 0 to 3 hours. There is a limitation in using range to tell the spread, however. so the difference between the most time spent surfing the internet and the least time surfing the internet would be the answer.

there are no answer choices

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
