A point in the figure is selected at random. Find the probability that the point will be in the part that is NOT shaded.
creativ13 [48]

Answer:

About 20%

Step-by-step explanation:

The probability of a point on the un-shaded region will be given by;

Area of the shaded region/total area

Considering that the circles are of the same size, then the length of the square is 2d

Area of the square = 4d²

Area of the shaded = (4d² -4π(d/2)²

                                = 4d² -πd², but π = 22/7

                                = 6/7d²

Probability = (6/7d² ÷ 4d²) × 100%

                  = (6/28 d²) × 100%

                  = 21.42 %

Therefore; the answer is about 20%

Determine which of the following function have a positive rate of change. Explain your answer.
olga2289 [7]

Answer:

  y = 2x - 11

Step-by-step explanation:

The "rate of change" is the coefficient of x when the function is written in this form:

  y = mx + b

That coefficient will be positive when the function has a positive rate of change.

  y = 2x - 11 . . . has a positive rate of change
