Answer:

Step-by-step explanation:

We need to pick the simulation that most closely has 15% "rotten".

In the first one, 3 read "rotten" out of 30. 3/30 = 10%.

In the second one, 3 read "rotten" out of 20. 3/20 = 15%.

In the third one, 3 read "rotten" out of 15. 3/15 = 20%.

In the fourth one, 3 read "rotten" out of 12. 3/12 = 25%.

So the second simulation best models the scenario.

Write a rule for the nth term of the geometric sequence if r = 1/4 and a3 = 2.

GarryVolchara [31]

Answer:

$a_{n} = 32(\frac{1}{4})^{n-1}$

Step-by-step explanation:

The nth term of a geometric sequence is given by the following equation.

$a_{n+1} = ra_{n}$

In which r is the common ratio.

This can be expanded for the nth term in the following way:

$a_{n} = a_{1}r^{n-1}$

In which $a_{1}$ is the first term.

This means that for example:

$a_{3} = a_{1}r^{3-1}$

$a_{3} = a_{1}r^{2}$

$2 = a_{1}(\frac{1}{4})^{2}$

$2 = \frac{a_{1}}{16}$

$a_{1} = 32$

Then

$a_{n} = 32(\frac{1}{4})^{n-1}$

What is the greatest common factor for 84 and 56?

anzhelika [568]

Factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

<span>Factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, </span>28, 42, 84

The outside term multiplies by the outside term on the oposite side to equal the answer.

Example:
Look at the factors of 84
84X1=84
2X42=84
3X28=84
and so on!
