Star with the statement: "Given that the sum is 11"
which may seem a bit odd considering its the last part of the problem
The "given" is important as it sets up the constraints of what we're dealing with. In this case, we know 100% (we can see or someone told us without lying) that the sum is 11. We don't know what the individual values are but we know they add to 11.
What are the ways to add to 11? Well they are...
5+6 = 11
6+5 = 11
so there are 2 ways to do it. As you can see, none of those ways involve a double. A double is where we have two of the same values (eg: snake eyes which is 1 and 1 giving 1+1 = 2 as the sum). It turns out that it's impossible to have doubles add to any odd number.
So if we know the sum is 11, and we're asking "what is the probability of rolling doubles", then the answer is 0.
The 0 indicates "impossible" or "certainty of it never happening".

Answer:
neither
Step-by-step explanation:
(-3,1), (-7,-2)
Slope of the line containing point (-3,1), (-7,-2) is
Slope of the line containing point (2,-1), (8,4) is
Slope of both the lines are not same, so they are not parallel
the slope of both the lines are not negative reciprocal of one another
So they are not perpendicular
Hence they are neither parallel nor perpendicular.
When you multiply powers, (add) the exponents.
When you divide powers, (subtract) the exponents.
When you raise a power to a power, (multiply) the exponents.
Anything to the zero power equals (1).
When you have a negative exponent, (flip it) and make it (positive).
33) A
34) 3/(x^2)
35) 192 * x^5 * y^11
One of the requirements of a rectangle is that it must have four right angles ( a right angle is 90 degrees) so you just multiply 90 by 4 and you get 360 degrees
