Two unfair dice are rolled independently. The first has 0.5 probability of landing on a 6,with equal probability for the other f
aces. The second has 0.1 probability of landing on a 1,with equal probability for the other faces.LetXbe the sum of the numbers appearing on the two dice, and letYbe the product.Compute the following, leaving your answer as a single decimal number:(a)E(X)(b)E(Y)(c)V(X)Note:Calculator use is allowed.

Answer:
(B) Time (min) 2 , 3 , 7 , 9
Temperature (°C) 60.6 , 64.3 , 79.1 , 86.5
Step-by-step explanation:
The rate of change is found by using the formula for slope:
For option A, this gives us
m =(64.4-61.0)/(3-2) = 3.4/1 = 3.4
This is not more than relationship A.
For option B, we have
(64.3-60.6)/(3-2) = 3.7/1 = 3.7
This is more than relationship A.
For option C, we have
(65.3-61.8)/(3-2) = 3.5/1 = 3.5
This is not more than relationship A.
For option D, we have
(64.6-61.0)/(3-2) = 3.6/1 = 3.6
This is not more than relationship A.
