Answer: in explanation
Step-by-step explanation
Sandi can perform 1/9 of the task in a day
Eva can perform 1/5 of the task in a day
Working together, they can perform
1/9 + 1/5 of the task per day
= 5/45 + 9/45 = 14/45 of the task in a day
or 45/14 days in the task = 3.2 days
So
It would take about 3.2 days to complete the task working togethe
Answer:
CAB = 54
ABC = 21
ACB = 105
DCB = 75
Step-by-step explanation:
18x - 15 = (13x - 11) + (4x + 1)
18x - 15 = 17x - 10
x = 5
CAB = 13x - 11 = 13(5) - 11 = 65 - 11 = 54
ABC = 4x + 1 = 4(5) + 1 = 20 + 1 = 21
ACB = 180 - (CAB + ABC) = 180 - (54 + 21) = 180 - 75 = 105
DCB = 180 - ACB = 180 - 105 = 75
If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information.
As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.
The ranges shown in both Frequency Table and Histogram are the same.
So, the following options are correct:
<span>B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.</span>
