Answer:

  0.6625 square inch

Step-by-step explanation:

The area of the central square in square inches is

  area = s²

     = 0.25² = 0.0625.

The area of each triangular side is ...

  area = 1/2bh

     = 1/2·0.25·1.2 = 0.15

So, the sum of the areas of the four sides and the base is ...

  4(0.15) +0.0625 = 0.6625 . . . . square inches

A wheel has 10 equally sized slices numbered from 1 to 10.
Ksenya-84 [330]

The random probability of event X, wheel stopping on a white slice is 0.9 while the probability of not X, wheel stopping on Grey slice is 0.1

  • Total numbers on wheel = total possible outcomes = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

  • Grey colored portion = {3}

  • White colored portion = {1, 2, 4, 5, 6, 7, 8, 9, 10}

  • X = Event that wheel stops on a white slice

  • P(X) = number of white slices ÷ total number of slices

  • P(X) = 9 / 10 = 0.9

  • P(not X) = 1 - P(X)

  • P(not X) = 1 - 0.9 = 0.1

Therefore, the probability that wheel stops on a white slice is 0.9 while, the probability that wheel does not stop on a white slice is 0.1
