Answer:

Step-by-step explanation:

Exactly two numbers appear:

There are  

(

)

(62)

ways for two of the six numbers to appear. On each of the six rolls of the die, there are two possible outcomes, giving

)⋅

2

6

(62)⋅26

possible outcomes in which two of the six numbers appear. However, of these  

2

6

26

sequences, there are two in which the same number is rolled six times. Thus, the probability of exactly two numbers appearing in six rolls of the die is

Answer:

h = -t+20

After 8 hours the candle will be 12 inches

Step-by-step explanation:

We have 2 points (time, inches)

 (3,17)  and (5,15)

We can find the slope

m = (y2-y1)/(x2-x1)

   = (15-17)/(5-3)

   = -2/2

   = -1

We can use point slope form

y-y1 = m(x-x1)

Replace y with h and x with t

h-17 = -1 (t-3)

Distribute

h-17 = -t+3

Add 17 to each side

h-17+17 = -t+3+17

h = -t+20
