johanna graphed the number of calls she made during one day. how many calls were made before 6 p.m.? cell phone calls
Answer
Explanation:
Step1: Identify relevant time - intervals
We need to consider calls made from 10 a.m. - 11:59 a.m., 12 p.m. - 1:59 p.m., 2 p.m. - 3:59 p.m., 4 p.m. - 5:59 p.m.
Step2: Read number of calls for each interval
From the bar - graph, number of calls from 10 a.m. - 11:59 a.m. is 2, from 12 p.m. - 1:59 p.m. is 8, from 2 p.m. - 3:59 p.m. is 0, from 4 p.m. - 5:59 p.m. is 9.
Step3: Calculate total number of calls
Add the number of calls in each relevant interval: $2 + 8+0 + 9=19$.
