Answer:
negative direction
Step-by-step explanation:
<em>A negative and a positive make a negative:</em>
1/5 + (-4/5) = 1/5 - 4/5

Answer:
transformed function, g (x) = (1/5)(-x)+7
Step-by-step explanation:
Assuming
f (x) = -x (and not f(x)-=x)
To compress/expand, we apply
g (x) = a*f(bx-k)+h
where
a=vertical stretch factor, a= 1/5 for compression (to stretch 5 times, a=5)
b=horizontal compression factor (=1 i this case)
h=vertical translation (=7)
k=horizontal translation (=0)
So the transformed function,
g (x) = (1/5)(-x)+7
Answer:
Step-by-step explanation:
The expected return is given as
Expected Return = SUM (Return i x Probability i). i=1,2,3.....
First investment
Probability of 0.7, it returns 60cents per dollars
Second investment
Probably of 0.3, it loses 20cents per dollar.
Expected return=(0.7×60)-(0.3×20)
Excepted return= 42-6
Excepted return=36cents
To dollars, 1cents is 0.01dollars
Then, 36cents = 0.36dollars
Expected return=$0.36
