Just plot the values onto a normal number line
<span>C. No, because although the results differ among the four surveys, the sample method used for all was the same. Luc RANDOMLY selects 40 students in every survey. Random selection in surveys do not create bias and the results are highly credible. This is because there are no preconceived notions or factors that affect the responses of people being surveyed.</span>
Surface of a cubical box=6(side²)
1)We have to calculate the surface of this cubical box.
Rate=cost of painting / surface ⇒surface=cost of painting/rate
Data:
Rate=$15/m²
cost of painting=$1440
Surface=$1440/($15/m²)=96 m²
2)We find out the length of the side:
Surface of a cubical box=6(side²)
Data:
Surface of a cubical box=96 m2
Therefore:
96m²=6 (side²)
side²=96 m²/6
side²=16 m²
side=√(16 m²)=4 m
3) We find the volume of a cubical box.
volume=(side³)
volume=(4 m)³
volume=64 m³
Answer: the volume of this cubical box would be 64 m³.
It is actually quite simple: they are asking for the probability:
there are different types of items and each types there is always at least a 25 cent difference in between (if you go up the or down the scale there will be a 25 cent difference to each type of item. They say that Sam wants to get one of the 8 items. The price at this point doesn't matter. If he wants 1 of the 8 types all you have to do is convert it into a fraction: 1/8. That is the answer
Hope I helped...
