nalin [4]

Total frequency = 56.

          Total fx = 1717

          midpoint of 45-49 = 47

          Mean of the data = 30.7

          Median of the data = 31.3

          Mode of the data = 32.5

<h3>What is Mean?</h3>

A measure of central tendency (also referred to as measures of centre or central location) is a summary measure that attempts to describe a whole set of data with a single value that represents the middle or centre of its distribution.

Here, total frequency  ∑f = 5+7+9+11+8+7+5+4

                                    = 56       (option B)

Total fx or ∑fx = 12X4 + 17X5 + 22X7 + 27X8 + 32X11 + 37X9 + 42X7+ 47X5

                        = 48 + 85 + 154 + 216 + 352 + 333 + 294 + 235

                        = 1717               (option B)

The midpoint of the score 45-49 = (45 + 49)/2  

                                                        = 47         (option B)

Mean of the data = ∑fx/ ∑f

                             = 1717 / 56

                             = 30.7                      (option D)

Median of the data = 31.3                (option A)

Mode of the data = 32.5                  (option B)

Thus, Total frequency = 56.

          Total fx = 1717

          midpoint of 45-49 = 47

          Mean of the data = 30.7

          Median of the data = 31.3

          Mode of the data = 32.5

.divide the problem.
quester [9]

Answer:

x - 2x - 15  \: divided \: by \: x - 3

  1. according to the above x²-2x-15 divided by the number below x-3 first I cancel out the x
  2. x  - 2x - 15 \: divided \: by \:  - 3
  3. the we solve the next x-5 divided by x²-9 then as usual rule out the x
  4. - 5 \: divided \: by \: x - 9
  5. now we only have x-2x-15 divided by-3 divided by-5÷x-9 now our next step is to again single the equations out
  6. x - 2x - 15 \: divided \: by \:  - 3 \: lets \: rue \\s \: rule \: out \:  - 3 \: and \: 15 \: giving \: us \: x - 2x - 5
  7. now the next -5 divided by x-9 here there's nothing to rule out therefore the sign "÷" is changed to "×" cancel out the -5 and therefore we have
  8. x - 2x = x - 9 \: as \: final \: answer
