Answer:
-868
Step-by-step explanation:
-Absolute change is simply defined as the number by which a change has occurred.
-We therefore determine the difference between the two years by subtracting the new value from the old or reference value:

Hence, the absolute change is -868
No the square root of 16 is 4 which is a whole number therefore it is rational not irrational
Answer:
D. DE = 24 yd, EF = 10 yd
Step-by-step explanation:
Solve for the unknown angles by setting up common ratios and cross multiplying. You can use this method because they are similar triangles.
For example, DE can be found by setting the ratios of AC/AB equal to the ratio of DF/DE.
13/12 = 26/x
Simply solve for x!
7x - 9 = 28 + 4x - 4
7x - 4x = 28 - 4 + 9
3x = 33
x = 11
One possible probability is 1/10.
Since P(b) = 1/5, we know that there must be some multiple of 5 as the total number of markers.
There cannot be 5 markers in the box; if there is only 1 blue out of 5 markers, it is impossible for there to be any red markers and have a probability less than 1/5.
Using a total of 10 markers, there would be 2/10 blue to have a probability of 1/5. This means there would be 1/10 red. We know nothing about the number of green markers, so there can be as many as we want, in theory. This means the other 7 markers could be green.
