Answer:
100 paws
Step-by-step explanation:
the ratio is 4:1 and you need to know is how many paws there are for 25 tails. if you divide 25 by 1 the answer is 25 and if you multiply 1 by 25 you get 25 and if you multiply 4 by 25 you get 100. (you multiply 4 by 25 because 1 was multiplied by 25 to get the amount of tails)
A. 3.45%
The formula for a proportion is x/n, "n" is the total of objects and "x" is the number os successes. In this case "defective" is the success because you want to know the percentage for defective parts, so 4/116= 0.0345 and you have to multiply the result by 100 and you get your answer in percentage.
