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%
X=6
First subtract 11 from both sides and you'll get 5x^2=180 then divide 180 by 5 which equals 36 you get x^2=36 find square root of 36 is 6
Answer:
Mm I didn't get the picture
Answer:
Step-by-step explanation:
6(-2.1k-2)+(7k+5)
-12.6k-12+7k+5
-5.6k-7
I believe the answer to your question is the first choice.
Since we have two sides that are 24 mm that means that the equation needs to have 2(24 mm).
And since we have 4 sides that are 18 mm, it means that the equation needs to have 4(18 mm).
so we get: P= 4(18 mm) + 2(24 mm)
Hope this helped and plz mark as brainliest!
