Because statistics tell us what the presents trends are now or were that can be projected into future.
Answer:
x=y+v/b
Step-by-step explanation:
So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
Answer:
Option D.
Step-by-step explanation:
In order to resolve this problem, we are going to transform every fraction on a decimal number.
A)
is a mixed fraction. To get a proper fraction, we let the denominator as 2, and to get the numerator we multiply 2 by 2, and we add 1, as seen on the attached picture.
So:

We divide 5 by 2 and we get 2,5.
So, the first option is not true, as 1.5 is smaller than 2,5.
B) We divide 1 by 2 and get 0,5. They are equal numbers, we can't say that 0,5 is bigger than 0,5.
C) -2.5 is smaller than -1,5 so this option is not true.
D) 
We divide 7 by 2 and we get -3,5. In fact, -3,5 is bigger than -4.5, as there is a major distance from this negative number to cero.
