Answer
7.5 pounds
Step-by-step explanation:
Since adding x grams of salt will bring th percentage of the salt to 25
Hence. 10% of the 50 gram gives. 5 gram initial salt before it is added.
5+ x/ 50 * 100= 25/
5+x /50 = 0.25
5+x = 12.5
X= 12.5- 5
X= 7.5pounds
Answer:
![P(A \: and \: B) = 0.048](https://tex.z-dn.net/?f=P%28A%20%5C%3A%20and%20%5C%3A%20B%29%20%3D%200.048)
Step-by-step explanation:
Recall that the probability of event A , given that event B has occurred is given as:
![P(A|B)=\frac{P(A\cap B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%7CB%29%3D%5Cfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D)
Since P(A|B) = 0.08 and P(A) = 0.40 are not the the two events are not independent.
We substitute the probabilities to get:
![0.08=\frac{P(A\cap B)}{0.60}](https://tex.z-dn.net/?f=0.08%3D%5Cfrac%7BP%28A%5Ccap%20B%29%7D%7B0.60%7D)
![P(A\cap B) = 0.08 \times 0.6 = 0.048](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%20%3D%200.08%20%5Ctimes%200.6%20%3D%200.048)
Therefore
![P(A \: and \: B) = 0.048](https://tex.z-dn.net/?f=P%28A%20%5C%3A%20and%20%5C%3A%20B%29%20%3D%200.048)
The answer simplified is 9ax^2y+9axy^2+9bx^2y+9bxy^2 but if your factoring it it’s 9xy(x+y)(a+b)
