Answer:
y = 22.5 - 0.2t
Step-by-step explanation:
Given;
total number of candle, n = 22.5 ounce
Rate of candle burn, R = 1 ounce per 5 hours
The amount of candle left = total initial value - amount burnt
let the amount let = y
y = 22.5 - 0.2t
where;
t is the time in which the candle is burnt
Thus, the equation for the amount of candle left is given by;
y = 22.5 - 0.2t
Answer:
Option C.
Step-by-step explanation:
The original value of Investment = $3,000
It has a 10% chance of ending up with a value of $2,000.
Chances of loss of $1000 = 0.1
It has a 80% chance of ending up with a value of $3,500.
Chances of profit of $500 = 0.8
It has a 10% chance of ending up with a value of $4,000.
Chances of profit of $1000 = 0.1
Expected change in the value of investment is
The expected change in the value of the investment is $400.
The expected value of an original Investment of $3,000 is
Therefore, the correct option is C.
