Answer: D

Step-by-step explanation:

Since we are given that the x value is -1, we can eliminate A and C because the -1 is in the y coordinate.

To find the proper y value, we plug x into the equation.

y=-2x+5                                                 [plug in x=-1]

y=-2(-1)+5                                              [multiply -2 and -1]

y=2+5                                                    [add 2 and 5]

y=7

Now that we have the y value, we know the coordinate (-1,7) which makes D the correct answer.

A dartboard consists of a circle inscribed in a square. The area of the circle is 16π square centimeters. The area of the square
lapo4ka [179]

The solution would be like this for this specific problem:

 

Area of Circle = 16(π)

= 16 * 3.14

= 50.24


Area of Square = 64

= 64 – 50.24

= 13.76

 

Area of Square but not on the circular board = 13.76 / 64

= 0.215

Percentage value = 0.215 * 100%

= 21.5%

So, <span>to the nearest percent, the probability that the dart lands inside the square but not on the circular dartboard is 21.5%.</span>
