im confused please explain better
Step-by-step explanation:
The correct answer would be more than 2,000 (approximately 2,205) because on the first he did 30, the second was 33, third was 36, and so on. You would have to make a chart for this, which could be somewhat boring, or you could write it out and do 30+30+3+30+6+30+9, etc for 30 different days, with 30 being for each day and progressively adding 3. Hope this helped!
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.
X / (x^2-36) - 6/ (x^2-36)
= (x - 6) / (x^2 - 36) Answer
