Answer:
9, -4, 3b, and 7a
Step-by-step explanation:
The events
are independent if and only if
. Under this condition, we have conditional probabilities
![P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{P(A)\cdot P(B)}{P(B)}=P(A)](https://tex.z-dn.net/?f=P%28A%5Cmid%20B%29%3D%5Cdfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D%3D%5Cdfrac%7BP%28A%29%5Ccdot%20P%28B%29%7D%7BP%28B%29%7D%3DP%28A%29)
![P(B\mid A)=P(B)](https://tex.z-dn.net/?f=P%28B%5Cmid%20A%29%3DP%28B%29)
so the answer is D.
time taken to make bed = 15.75 hours
time taken to make a coffee table = 6.375 hours
time taken to make a dresser = 9.5 hours
Total time =
![2(15.75) + 6.375 + 3(9.5)](https://tex.z-dn.net/?f=2%2815.75%29%20%2B%206.375%20%2B%203%289.5%29)
![= 66.375](https://tex.z-dn.net/?f=%20%3D%2066.375)
![66 \frac{3}{8}](https://tex.z-dn.net/?f=66%20%5Cfrac%7B3%7D%7B8%7D%20)
The answer would be 60 degrees
I arranged the numbers to their correct position.
