Answer:
Step-by-step explanation:
41 + 4x = 7x + 5(Exterior angle theorem)
36 = 3x
Hence x = 12

Answer:
0.5%.
Step-by-step explanation:
The definition of percent is 'parts per 100'.
0.5 / 100 = 0.5 percent.
Answer:
a. 55.56%
b. 44.44%
c. 3.33%
d. 33.33%
Step-by-step explanation:
total supply = 180
a. In the first factory the total number obtained = 100
probability that the chosen part is from the first
= 100/180
= 0.5556
= 55.56%
b. In the second factory total = 80
probability that the chosen part is from the second
= 80/180
= 0.4444
= 44.44%
c. probability that part chosen at random from 180 is defective
= 2% * 0.5556 + 5% * 0.4444
= 0.02*0.5556 + 0.05*0.4444
= 0.011112 + 0.0222
= 0.03331
= 3.33%
d. probability it came rom the first factory if it is defective

= 
= 
= 0.33357
= 33.33%
Hope this helps!
Stay safe, have a good day :D
