deff fn [24]

Answer:

$68.24

Step-by-step explanation:

Three friends went to Texas Roadhouse for dinner. The total bill was $76.25. They left the server a 20% tip and the Montgomery County tax rate is 9.5%.

Given data

The total bill was $76.25

tip

=20/100*76.25

=0.2*76.25

=15.25

Tax

=9.5/100*76.25

= 0.095*76.25

=$7.24375

In all the bills is 76.25-15.25+7.24375

=61+7.24375

=$68.24

Bea is building a 1:120 scale model of a museum building. Her model has a rectangular base that is 3 feet wide and 2 feet long.

NemiM [27]

Area of the base of the model
3*2 = 6 square feet

Since the actual building 120 times bigger than the model, it should be multiplied with 120
6*120 = 720 square feet

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

Rina8888 [55]

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!
