What is the mean of these set of numbers {–8, –4, –3, –11}?

1 answer:

6 0

I think the correct answer among the choices listed above is option A. Mean is synonymous to the average of the set of numbers. It is calculated by adding up the numbers divided by the number of data added.

Mean = (-8 + -4 + -3 + -11) / 4 = -6.5

For the finite sets, Cantor's theorem can be affirmed to be true by plain enumerating the number that are in the subsets.

38 degrees.
EXPLANATION

There are 2 angles.

The angles must add up to 180.

So taking 180 and subtracting the already known angle, of 142.

Will get us with 38.

We can check the work by doing 38 + 142.

Hope this helps! have a gud day
