The height of the candles when they first burn down to the same height is 10 cm
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let y represent the height of the candle after x hours.
For the first candle:
y = -(5/6)x + 15
For the second candle:
y = -(5/2)x + 25
To have the same height:
-(5/6)x + 15 = -(5/2)x + 25
x = 6 hours
y = -(5/2)(6) + 25 = 10 cm
The height of the candles when they first burn down to the same height is 10 cm

Answer:
Prob [All marbles are red] = 0.0686 ;
Prob [None marble is red] = 0.1470
Step-by-step explanation:
Prob [All marbles are red] :-
= Prob(1st red marble & 2nd red marble & 3rd red marble)
= 8/18 x 7/17 x 6/16
= 0.0686
Prob [None marble is red] :-
= Prob (1st marble not red & 2nd marble not red & 3rd marble not red)
= 10/18 x 9/17 x 8/16
= 0.1470
