Answer:a
Step-by-step explanation:
Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
= 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
= 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
= 355.95/100 dollars
= 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
= 172.04/100 dollars
= 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
= 29.01 dollars

Answer: Option B
Step-by-step explanation:
First we assign a name to the events:
Event S: a customer buys socks
Event H: a customer buys shoes.
We know that :
We also know that the probability of S given that H occurs is:
If two events S and H are independent then:
This mean that if two events S and H are independent then:
We know that:
and
This means that S and H events are dependent.
The answer is the option B
I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
