What is the probability that a point chosen at random in the rectangle is also in the blue triangle

The probability that a point chosen at random in the rectangle is also in the blue triangle is:

1/2

Step-by-step explanation:

We are given a figure

We have to find the probability that a point chosen at random in the rectangle is also in the blue triangle.

Area of rectangle= 4×5 sq. in.

                            = 20 sq. in.

The area of blue triangle=

                                         = 10 sq. in.

P(that a point chosen at random in the rectangle is also in the blue triangle)

 = area of blue triangle/whole area of the rectangle

= 10/20

= 1/2

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
