Since we have given that
30% chance that the company will lose $30000.
40% chance of a break even that there is no loss and no profit.
30% chance that the company will profit $ 60000.

Answer:
D
Step-by-step explanation:
For a function in the form f(x) = x, we can say:
- the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
- the function -f(x) is the original, flipped over x-axis
<em>keeping the 2 rules in mind, we can say that</em>
<em>vertical stretch by a factor of 3 would make it f(x) = 3x</em>
<em>Then</em>
<em>flip over x-axis would make it f(x) = -3x</em>

answer choice D is right
Answer:
procedure always produces 6
Step-by-step explanation:
Let 'n' be the unknown number
Add 4 to the number : n+4
multiply the sum by 3.
multiply the sum n+4 by 3

Now subtract 6, so we subtract 6 from 3n+12

finally decrease the difference by the tripe of the original number
triple of original number is 3n

so the procedure always produces 6
