Answer:
5/8
Step-by-step explanation:
The answer is c.16 because he spent 50 minutes on his homework and 32 percent of 50 is 16
To determine if 30,150 resistors is enough to make 1,922 radios, we do ratio and proportion. In this kind of solution, we base it on a fixed ratio as given by 15 working resistors is to 1 radio. Moreover, you are given an additional detail of probability. All you have to do is multiply the probability to the total resistors to determine the exact amount of working resistors. Since the probability of defect is 1/25, by difference, the probability of a working resistor is 1-1/25 = 24/25.
Therefore,
15/1 ≤ 30150(24/25)/1922
15 ≤ 15.06
The symbol '≤' means less than or equal to. It is the inequality to be used because 15/1 is the minimum limit. As long as the ratio is equal to 15 or more than 15, then 30,150 is enough to make 1,922 radio. Since it is true that 15.06 is greater than 15, then the amount of resistors would be enough.
Answer:
35.6 m
Step-by-step explanation:
Number of revolutions = 40
Length of thread = 0.89 m
Total Distance = Number of revolutions * Length of Thread
Total Distance = 40 * 0.89 = 35.6 m
