Ok so let’s write out the problem
4x+6=-x+1
We first want to get the x’s on one side and the numbers on the other

4x+6=-x+1
+x. +x

5x+6=1

Now we want to get the 6 over

5x+6=1
-6. -6

5x=5

Divide by 5 to get the x alone
X is equal to 1

At a restaurant, 80 percent of the diners are new customers P(N)=0.8, while 20 percent are regular customers P(N’)=0.2. And, 50

Answer:

c. 0.7404

Step-by-step explanation:

We can use Bayes Formula,

$P(N|C) = \frac{P(C|N)*P(N)}{P(C)}$

We know every single value of that expression except P(C). We can calculate C by dividing into 2 cases: if the customer is new or not.

By the total probability theorem, we know that P(C) = P(C|N)*P(N) + P(C|N')*P(N') = 0.5*0.8 + 0.7*0.2 = 0.4+0.14 = 0.54

We replace P(C) on the equation above and we obtain

$P(N|C) = \frac{P(C|N)*P(N)}{P(C)} = \frac{0.5*0.8}{0.54} = 0.7407$

Thus, P(N|C) = 0.7407. Answer c is correct

I hope this helped you!
