77.5%

Step-by-step explanation:

see the attached figure to better understand the problem    

step 1

Find the radius of the circle

The area of the circle is

we have

assume

substitute and solve for r

step 2

Find the area of the square outside the circle

The length side of the square is the diameter of the circle

step 3

Determine the area of the blue region

The area of the blue region is the area of circle minus the area of the square inside the circle

step 4

The probability that a point chosen at random is in the blue region is equal to divide the area of the blue region by the total area of the outside square

310/400

simplify

31/40=0.775

Convert to percentage

0.775*100=77.5%

Lets get this right, it is D. 155/157

Step-by-step explanation:

Area of square is 4, area of circle is 314. To find area of blue do 314-4. To find area you get 310/314. Simplify by dividing both by 2, you get 155/157.

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
