Answer:the number of adult tickets that were sold is 160
the number of students tickets that were sold is $125
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of students tickets that were sold.
A total of 285 tickets are sold. This means that
x + y = 285
Adult tickets are $4 and student tickets are $1. A total of 285 tickets are sold for $765. This mean that
4x + y = 765 - - - - - - - - - - 1
Substituting x = 285 - y into equation 1, it becomes
4(285 - y) + y = 765
1140 - 4y + y = 765
- 4y + y = 765 - 1140
- 3y = - 375
y = - 375/-3 = 125
Substituting y = 125 into x = 285 - y, it becomes
x =285 - 125 = 160 tickets
How to find the MAD:
1) Add all numbers
2) divide by a number of numbers given
3) if told, round
1. The mean absolute deviation of a set of data is the average distance between each data value and the mean. The mean number of contacts stored and the distance each data value is from the mean is shown below. Each data value is represented<span> by an ×.
the mean MAD is 129.4. rounded, it will be 129.
2. splash of lagoon: 89.6 rounded is 90
wild water bay: 116.6 rounded is 117
The height of the waterslides at splash lagoon varied less than the height of the water slides at wild water bay. The waterslides at wild water bay varied more probably because they overall were taller waterslides.</span>

The function f(x) = x² then the required function exists g(x) = -x²- 4.
<h3>What is a function?</h3>
The function exists described as y = f(x).
In mathematics, a function from a set X to a set Y allocates to each element of X exactly one element of Y. The set X exists named the domain of the function and the set Y exists named the codomain of the function. Functions stood originally for the idealization of how a variable quantity relies on another quantity.
For every x there exists a certain value of y.
From the graph g(x) exists reflection of f(x) at y = -4.
So g(x) = -f(x) - 4, the negative sign for reflection.
g(x) = -x² - 4
The required function exists g(x) = -x² - 4.
Therefore, the correct answer is option D. g(x) = -x² - 4.
