Answer:0.77
Step-by-step explanation:
Let A be the specification of first components and B be the specification of second component
Let P(A) be the probability that A meets specification and P(B) be the probability that B meets specification.
Probability mass function of the number of components in the assembly that meet specification = P(A) × P(B) (since they are independent)
X= 0.91×0.85
X= 0.77
Answer:
∠A=60
∠B=30
Step-by-step explanation:
∠A+∠B=90
So if then because 60+30=90
I hope that was enough explanation.
Have a nice day :) (please give me brainliest, I'm trying to reach the next rank, thank you)
Answer:
First from 18, you count to 23. So, 19, 20, 21, 22, 23. There were only 5 more pounds needed, so it would be, 1 full package of 18 pounds and 1 quarter of a package (I think), because it is not a full package, another full package of 18 would be 36 pounds. I hope this helped! [It might not]
42/12 = 3.5, 63/18 = 3.5, therefore we will be multiplying the last time by 3.5. 40x3.5= 140, and therefore, the number of pencils produced in 40 seconds is 140
