Answer: 5/36
Step-by-step explanation: We know that A U B means all the possible combinations that make event A or event B true. As we know, the only combinations that can make 4 is 1+3, 2+2, or 3+1, and the only combinations that can maker 11 is 5+6 and 6+5. This leaves us with a total of 5 combinations, and with a total of 36 combinations, that means that there is a 5/36 chance that the combinations of the dice add to either 4 or 11.
Answer:
it is not a direct variation
Step-by-step explanation:
To have a direct variation
y/x = k for all values of x and y
y/x = 11/7
y/x = 13/8
y/x = 15/9 = 5/3
y/x = 17/10
11/7 does not equal 13/8 so it is not a direct variation
Answer:
15 cm, 15 cm, 11 cm
Step-by-step explanation:
let the equal sides be x then the third side is x - 4
The perimeter is the sum of the 3 sides and is 41 cm , then
x + x + x - 4 = 41
3x - 4 = 41 ( add 4 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
x - 4 = 15 - 4 = 11
The sides are 15 cm, 15 cm, 11 cm
