5 pencils cost $.80. Each pencil costs $0.16
Then divide $0.16 into $0.40
This equals 2.5 pencils, you can't buy half a pencil

jarptica [38.1K]

Answer:

20 red tiles

Step-by-step explanation:

14 green tiles,10 red tiles, and 16 blue tiles. = 40 tiles

P(red) = 10/40 = 1/4

If we draw 80 tiles

80 * 1/4 = 20

We should expect 20 red tiles

Match the graph of the function with the function rule.
PIT_PIT [208]

By applying the definition of <em>exponential</em> function, we find that the function f(x) = 3 · 2ˣ match with the graph of the picture. (Correct choice: A)

<h3>What is the equation behind the exponential curve seen in the graph?</h3>

In this question we have the graph of a <em>exponential</em> function, whose expression have to be found based on the definition of <em>exponential</em> function:

y = a · bˣ      (1)

Where:

  • a - Initial value of the exponetial function.
  • b - Base of the exponential function.
  • x - Independent variable
  • y - Dependent variable

Now we find the values for a and b:

Initial value (x = 0, y = 3)

3 = a · b⁰

a = 3

Base of the exponential function (x = 1, a = 3, y = 6)

6 = 3 · a

a = 6 / 3

a = 2

By applying the definition of <em>exponential</em> function, we find that the function f(x) = 3 · 2ˣ match with the graph of the picture. (Correct choice: A)
