Can you help me find x? x/7+x/3=9/7

Mathematics

x/7 - x/3 = 9/7

x/7(3) - x/3(7) = 9/7(3)

3x/21 - 7x/21 = 27/21

3x - 7x = 27

-4x = 27

(1/-4) -4x = 27(1/-4)

x = -27/4

A and B are two events.
Vesna [10]
In order to determine if the events are independent or not we need to find the conditional probabilities.

The conditional probability of event A, given event B is denoted as P(A|B)

P(A|B)= \frac{P(A*B)}{P(B)}

P(A*B) indicates P(A and B)

Using the values, we get:

P(A|B)= \frac{0.28}{0.8}=0.35

Since P(A|B) is not equal to P(A) this indicates that occurrence of event B has an impact on the occurrence of event A. This shows that the two events are dependent.

Therefore, the correct option is the second one.
2. A and B are not independent events because P(A∣∣B)≠P(A)

Matt's steps will be more complicated since Annie is using a program to do the constructions hers would probably be precise and easy.
