Total number of possible outcomes = 36
Total number of outcomes with a sum of 12 = 1
{6,6)
Total number of outcomes with a sum of 3 = 2
{1,2}{2,1}
P(12 first, then 3) = (1/36)(2/36) = 1/648
Answer: The probability is 1/648
Answer:
x = 26
Step-by-step explanation:
Start with - 9 + x = 17, or -9 + x = 17
Solve for x by isolating x on the left side. To do this, add 9 to both sides, obtaining x = 26
Answer:
Step-by-step explanation:
If x represents the amount invested at 7%, then the amount invested at 13% is x+300. Lydia's total interest is ...
0.07x +0.13(x +300) = 252
0.20x = 213 . . . . . subtract 39
x = 213/0.20 = 1065
Lydia has $1065 invested at 7% and $1365 invested at 13%.
