6th graders = 52%
7th graders = 0.57x100 = 57%
8th graders = 2/5 x 100 = 40% so least to greatest will be
8th, 6th then 7th
Answer:
Step-by-step explanation:
Let x equal the first mile marker. Then x + 1 represents the second mile marker.
Then x + (x + 1) = 561, or
2x + 1 = 561, or
2x = 560, and so x = 280
Then the first mile marker reads 280 and the second mile marker reads 281.
I'll just show you how to make a frequency table using the above data.
We will group the data into class intervals and determine the frequency of the group.
<span>8 12 25 32 45 50 62 73 80 99 4 18 9 39 36 67 33
</span>
smallest data value = 4
highest data value = 99
difference = 99 - 4 = 95
number of data = 17
Let us assign a class interval of 20.
Class Interval Tally Frequency
0-20 8, 12, 4, 18, 9, 5
21-40 25, 32, 39, 36, 33 5
41-60 45, 50, 67 3
61-80 62, 73, 80 3
81-100 99 1
That is how a frequency table look like. Usually, under the Tally column, tick marks are written instead of the numbers but for easier monitoring, I used the numbers in the data set.
