The Answer: (-b + 15) (15 - b)
The correct answer should 4% because the ratio is 3 out of 75 which would leave 72 non-defective bulbs. So your answer is 4%
Her final score should be 21. You can add both 3 1/2 and 3 1/2 which will give you 7. Then substract it from 28.
Answer: f'(x) = - cos^2(sin(x^2))
Step-by-step explanation:
Derivative of:
f(x) = Sin^2(cos(x^2))
f'(x) = cos^2(-sin(x^2)
f'(x) = - cos^2(sin(x^2))
