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
Answer:
255
Step-by-step explanation:
The recursive formula is used to find the terms one-by-one, unless you convert it to an explicit formula.
first term (given): 3
2nd term = 4·3 +3 = 15
3rd term = 4·15 +3 = 63
4th term = 4·63 +3 = 255
_____
Looking at the sequence of terms, we see that an explicit formula might be ...
an = 4^n -1
Then the 4th term is
a4 = 4^4 -1 = 256 -1 = 255
_____
<em>Comment on the problem statement</em>
This is NOT an Arithmetic Progression. An arithmetic progression has a <em>common</em> <em>difference</em> between terms. Here, the differences are 12, 48, 192, numbers that are <em>different</em> from one pair of adjacent terms to the next.

x = -13/2 x=13/2
Step-by-step explanation:
(x+13/2) (x-13/2)=0
Using the zero product property
x+13/2 = 0 and x-13/2 =0
x = -13/2 x=13/2
