Answer:9x^4
Step-by-step explanation:
6x^4*3x^3 can be simplified to 18x^7 by separating out cand combining like terms [6*3 = 18] and [x^4*x^3 = x^7]
This results in 18x^7 fr the top term
Do the same for the bottom term: 2x^2*x = 2x^3
We can now write: (18x^7)/(2x^3)
The reduces to 9x^4
To answer the first problem, we determine first the equivalent z score and get the corresponding probability. The z score at 3 hours is (3-3.4)/0.5 = 0.8 while that of 4 hrs is <span>(4-3.4)/0.5 = 1.2. z score of 0.8 is equal to a probability of 0.2119 and that at 1.2 is 0.8849. The difference is 0.673. Hence answer is C.
For problem 2, the z score at 99% is 2.33 hence, the equation becomes 2.33 = (x-30)/6 where x is the noise level threshold. Answer is D. 43.96 decibels.</span>
