Answer: 
Step-by-step explanation:
The missing figure is attached.
You can notice that the design is a cube.
A cube has 6 faces which are all squares.
The area of a square can be calculated with this formula:
Where "s" is the length of any side of the square.
In this case, you can observe in the figure that:
Therefore, substituing that value into the formula, you get that the area of any of the cube's faces is:
Finally, in order to find the surface area of the cube, you need to multiply the area of a face calculated above, by 6.
Therefore, the surface area of the design is:
Answer:
y= -3x-1
Get the slope from the equation by getting y by its self then dividing everything by -1, which gives you y=-3x-12. You the -3 as your slope when doing the point-slope form.
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
