Answer:
5/36
Step-by-step explanation:
Probability is the outcome that a event will occur
Probability = Expected outcome/Total outcome
Since two sided dice are rolled, the total outcome will be expressed as;
Total outcome = 36
Since we are to find the probability that the sum is 8, the values that gives a sum of 8a re;
(2,6)(6,2), (5, 3), (3,5), (4, 4)
The expected outcome = 5
Probability = 5/36
Hence the probability that the sum is 8 is 5/36

Answer:
60 pounds
Step-by-step explanation:
To find the adult weight, multiply 12 by 5.
Since 12 pounds is 20% of the adult weight, 100% of the adult weight would be 12 times 5.
12(5)
= 60
So, the adult weight of the puppy will be 60 pounds
Answer:
492.99
Step-by-step explanation: x = amount invested at 12%
y = amount invested at 9%
---
x + y = 20287
0.12x = 0.09y + 492.99
---
put the system of linear equations into standard form
---
x + y = 20287
0.12x - 0.09y = 492.99
Substitute the value of the variable into the expression and simplify 37
