Answer:
P=0.61 or 61%
Step-by-step explanation:
If we pick a random point within the circle, it can fall in the white area or in the pink area. Since the sum of both areas makes the sample space or the total area of the circle, we can compute the probabilities according to the ratio of the areas with respect to the total area, that is:
The area of the circle is
The area of both the triangles is
Where r=4 cm, b=3 cm, h= (4+2.5) cm = 6.5 cm
Then we have:
The white area is obtained by subtracting both areas
So the probability is
Answer: Slope of the line is -9/7
Step-by-step explanation:
Given :
Points : (10,9) and (3,18)
Now slope of line when two points are given
m=
Slope =
m=
m=
This is an improper fraction since numerator is greater than the denominator
Hence slope of the line is -9/7
