2/5x+y=3
-2/5x -2/5x
y=-2/5x+3
Does y = to whole number or just like that? if it Whole number I will solve it tell me
The answer is No because the sample is not representative of the whole population. The standard deviation of the sample is not a good estimate of the variation of the salaries of the TV personalities in general because a single sample is not counted as a whole. Standard Deviation is a quantity that is calculated to indicate the extent of deviation of the population or group as a whole. Standard deviation also represented by the symbol σ means sigma in Greek letter or s in Latin letter. It is also the measurement of a set of data values that are used to quantify the amount of variation.
Think:
7:55 a.m. is 5 minutes (5/60 hrs) before 8 a.m.;
from 8 to noon it's 4 hours, and from noon to 2:40 p.m. is 2 2/3 hours.
Thus, you're in school 5/60 hrs + 4 hrs + 2 2/3 hrs, or
6 2/3 hrs + 5/60 hrs, or 6 40/60 hrs + 5/60 hrs, or
6 45/60 hrs, or 6 3/4 hrs.
Of course there are other ways in which you could do this problem:
4 hrs 5 min plus 2 hrs 40 min comes out to 6 hrs 45 min, or 6 3/4 hrs.
