Answer:

Step-by-step explanation:
line equation in general y = mx + b
m is the slope, and
b is the y-intercept
3=-3m+b
-7=3m+b
if we plus this two equations
3-7=2b
2b=-4
b=-2
3m=b-3=-5
m=-5/3
So,

You will find the area of the semicircle by finding the area of the circle with a radius of 8.5 mm and the dividing it by 2.
A = pi x r^2
3.14 x 8.5^2
A = 226.865 square mm
226.865/2
113.43
The approximate area of the semi circle is 113.43 mm².
Okay, so let's find the actual failure rate first. 6/1000 times 100 (to give over a 100%) equals to 0.6. The actual failure rate is 0.6%. The theoretical probability is 0.2% 0.6-0.2=0.4. The difference is 0.4%.
Hope that helped!
