It deals with proportions. You put hotdogs over minutes.
Like 10 hotdogs over 4 minutes because that's how long it took to eat those hotdogs.
Then put 18 minutes on the bottom of the next fraction.
Then you cross multiply.
10 x 18 which equals 180.
Then you divide. 180/4
Which equals 45 hotdogs.
He ate 45 hotdogs in 18 minutes.
10 hotdogs in 4 minutes
45 hotdogs in 18 minutes.

What is the median for 76,84,93,67,82,and 76

Lapatulllka [165]

First arrange the numbers from least to greatest:

67, 76, 76, 82, 84, 93

The median is the middle number. But since we have two numbers that are in the middle we have to find the average of them.

76 + 82 = 158
158/2 = 79

So your answer is 79

8. A computer application generates a sequence of musical notes using the function f(n) 6(16)", where n is the

s2008m [1.1K]

Applying an exponential property, it is found that the function that will generate the same note sequence as function f(n) is given by:

B. $H(n) = 6(2)^{4n}$

<h3>What is function for the note sequence?</h3>

The function for the node sequence is defined by:

$f(n) = 6(16)^n$

A function that will the same note sequence as function f(n) has the same initial value of 6. Additionally, applying an exponential property, we have that:

$H(n) = 6(2)^{4n} = 6(2^4)^n = 6(16)^n$
