Please answer the above question correctly while explaining and I will mark you as brainliest​

~(AuB) = ~A intersect ~B

{7,8} = {7,8}

Step-by-step explanation:

I. When ~ compliment means NOT or minus and universe is {1,2,3,... 8}

Find A union B and not A intersect not B

~(AuB) = ~A intersect ~B

~(1,2,3,4,5) = ~(2,4,5) intersect ~(1,2,3,5)

{1,2,3,4,5,6,7,8} - (1,2,3,4,5) = {1,2,3,4,5,6,7,8} - ~(2,4,6)

{7,8} = {1,3,5,7,8} - ~(1,3,5)

{7,8} = {7,8}

That makes ~(AuB) = ~A intersect ~B is true

Hope that help :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

one set of data has more variation than the other. hope this !
