Help with this math.

Mathematics
1 answer:
valentinak56 [21]3 years ago
6 0

Answer:

Step-by-step explanation:

Mean:  Add them all up then divide that sum by how many there are.

Median:  They are in number order, so that makes median and mode very very nice.  For an odd number of points, you choose the middle point, for an even number of points (which we have) take the two and find the average of those two.  That is, add the two up then divide them by two, it's basically taking their mean.  since there are 20 you take the 10th and 11th numbers.

Mode:  Again, super easy since they are in number order, just look for the number that appears the most.  If none do, there is no mode.  Hint, there is a number that appears twice.

       2b                     2a
----------------- +  -----------------
   (b+a)^2            (b^2 - a^2)

            2b                     2a
= ----------------- +  -------------------
      (b+a)(b+a)         (b+a)(b-a)

         2b(b - a) +  2a(b + a)
= ------------------------------------
           (b+a)(b+a)(b-a)


         2b^2 - 2ab  +  2ab + 2a^2
= ---------------------------------------
           (b+a)(b+a)(b-a)

         2b^2 + 2a^2
= ------------------------
        (b+a)(b+a)(b-a)

         2(b^2 + a^2)
= ------------------------
        (b+a)^2 (b-a)

Answer:

Numerator:        2(b^2 + a^2)
Denominator:    (b+a)^2 (b-a)
