This is more of a common sense problem rather than actual math.
Since we are trying to see the distribution of scores, it is not very practical to use 1 point. 15 and 20 point distributions are a bit big. Thus, the answer is 5 (most histograms in math class do use 5 for their scale).
Answer:
3/2x + 4
Step-by-step explanation:
3x - 2y = -8
-2y = -8 - 3x
y = 4 + 3/2x
Answer:
2.5 is 12PM temp and difference is 3.9
Step-by-step explanation:
-0.5+3 because it is warmer and this is 2.5 also both B and C can be done to get the correct answer. and that is 2.5--1.4 which is the same as 2.5+1.4 which is 3.9
Answer:
m = 0.257
Step-by-step explanation:
4.3 + 10m = 6.87 (subtract 4.3 from both sides)
10m = 6.87 - 4.3
10m = 2.57 (divide both sides by 10)
m = 2.57/10
m = 0.257
