Answer:
A sandwich shop offers:
Bread: 1 , 2
Meat: 1 , 2 , 3 , 4
Cheese: 1 , 2 , 3
Choose one to be your starting point. For example, choose Bread. You only choose one of each, so:
Bread 1, Meat 1, Cheese 1
Bread 1, Meat 1, Cheese 2
Bread 1, Meat 1, Cheese 3
etc. etc.
However, note that there is an easier way to solve it. In this case, you can use the <em>Fundamental Principle of Counting</em>, which each total number of choices are added together.
Multiply them:
Bread x Meat x Cheese = 2 x 4 x 3 = 24
There are 24 different types of sandwiches that can be made if only one of each is chosen.

F(x) = 4 - 2x Domain = x = -4, 0, 5
f(x) = 4 - 2(-4) = 4 - (-8) = 12
f(x) = 4 - 2(0) = 4 - 0 = 4
f(x) = 4 - 2(5) = 4 - 10 = -6
f(x) = 12, 4, -6
The range is C.
There would be 2.5 grams of the substance left
Answer:
7.18 / minute.
Step-by-step explanation:
The number of minutes in 2015 = 365 * 24 * 60 = 525,600.
So birth rate = 3,774,000 / 525,600
= 7.18
