Asquare of area 36cm is cut to make two rectangles a and b the ratio of area a to b is 2: 1 work ou the dimensions of rectangles a and b

The dimensions of rectangle a are 6x4 and dimensions of rectangle b are 6x2.

Step-by-step explanation:

We are given a square with area 36 squared cm. Therefore, dimension of the square will be 6 cm.

The square is cut into two rectangles with areas in the ratio 2:1.

Let the dimensions of the rectangles be 6*a and 6*b. Therefore, we can set up the ratio of areas as:

Moreover, we can set the combined area of rectangles equal to the area of square to form another equation:

Using substitution method, we can solve for 'a' and 'b' as shown below:

And

Therefore, dimensions of the two rectangles are 6x4 and 6x2, respectively.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
