Answer:
Step-by-step explanation:
For an exponential distribution, the standard deviation is equal to the mean.
(a) the standard deviation is 4 miles.
Well... Basically, you should prove this by SSS property(side-side-side). It's fair to say that the length of a side is equal to itself so The line that cuts through the rectangle is a side for both rectangles. Thus because of the given, all the sides of the triangles are equal to one another. This is a very important trick for geometry(I remember using it a lot).
Hope this helps!
Well 1/8 is smaller than 8/8 so they should not be equal
Answer:
3/8 < 3/6
This is because, when the common denominator (24) is found, the fractions are 9/24 (red) and 12/24 (yellow).
