Think about it... if the number is bigger than 5 you round up so.. 399 is rounded to 400.
Complete question :
Mr. Nelson lost one of his students' test papers. He knows that the other 4 students scored as follows: 60, 62, 56, 57. He also knows that the average score is 59.2. What is the score on the missing paper?
Answer:
61
Step-by-step explanation:
Given the following :
Total number of students = 4 + 1 missing = 5
Score on the four avaliable papers = 60, 62, 56, 57
Average score of the 5 papers = 59.2
Score on missing paper :
Sum of each score / number of papers
Sum of each score = sum of available scores + missing score
Let missing score = m
(60 + 62 + 56 + 57 + m) = 235 + m
Recall:
Average = total sum / number of observations
Hence,
59.2 = (235 + m) / 5
59.2 × 5 = 235 + m
296 = 235 + m
m = 296 - 235
m = 61
Missing score = 61
If 9<15mx-8<279<15mx−8<279, is less than, 15, m, x, minus, 8, is less than, 27, where mmm is a positive constant, wh

Answer:
The range of 
is (-9,-3).
Step-by-step explanation:
The given compound inequality is
We need to find the range of values of .
Let 
Divide each side of the given compound inequality by 3.
Multiply each side by -1.
If we multiply an inequality by a negative number, then the sign of inequality is changed.
Therefore the range of is (-9,-3).
<u><em>3 / 3/4 </em></u>
3/1 x 4/3 = <u><em></em></u><em><u>4</u></em><em>
