0.300

Step-by-step explanation:

Area circle      4^*pi =50.272

Area pentagon =area of the sum of 5 triangles

area of 1 triangle

(b*h)/2=

4.7* 3.2 divided into 2  =7.5

7.5*5 =37.5

subtract the area of the pentagon from the area of the circle:

50.272-37.5= 12.772

Divide the area remaining of the circle into the area of the whole circle to kow the probability:

12.772/50.272=0.254  (rounded to 0.300)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
