The length of a side of the triangle is 16.
Which is a Regular Polygon?A polygon is classified as regular when all sides and angles are equal. Therefore, a regular quadrilateral presents all the four sides and the four angles equal. You can use the same conclusion for a regular triangle, but for a triangle the three sides and the three angles are equal.
The question gives:
The perimeter for the regular quadrilateral = 48. Because of this, it is important that you know the definition for perimeter = sum of the sides of a geometric figure.As the triangle was classified as regular, all its sides (x) are equal. Then,
x+x+x=48
3x=48
x=48/3
x=16

A student went to the gas station to buy gasoline and a bag of potato chips. Gasoline was $2.31 per
gallon and potato chips were $1.25.
Part 1. Write a linear equation to model the total amount the student spent at the gas station,
where g represents the number of gallons of gasoline, and t represents the total amount of money
spent. Assume there is no tax.
Part 2. Suppose the student bought 16 gallons of gas. Find the total amount the student spent at
the gas station
Part 1. The linear equation is 2.31g + 1.25t = 0
Part 2. Total amount student spent at the gas station is $36.96
What is linear equation?
An equation between two variables that, when plotted on a graph, produces a straight line or say first degree equation is known as linear equation.
Part 1.
Here in question of part 1 it stated that
g = the number of gallons of gasoline
t = the total amount of money
So according to question, the linear equation will be
2.31g + 1.25t = 0
Part 2.
Given, 1g = $2.31
then, 16g = 16 * 2.31
= $36.96
Therefore, for Part 1. The linear equation is 2.31g + 1.25t = 0 and,

What percentage is the best prediction for the percent of people in an audience who will finish watching a documentary that is 27 minutes long? Round your answer to the hundredths place
Using the regression equation we can estimate that 60.49% of people will finish the documentary.
Regression analysis is a group of statistical procedures used in statistical modelling to determine the associations between a regression model and one or more relationship between the independent variable.
Y is the variable (the variable that is plotted on the Y axis), X is the independent variable (i.e., it is displayed on the X axis), b is the slope of the line, and an is the y-intercept.The equation has the form Y= a + bX.The equation is given as Y= - 0.434X+72.21
At X=27 , the value of Y can be estimated as :
Y = -0.434 × 27 +72.21
or, Y = 60.492
or, Y ≈ 60.49
Therefore 60.49 % is the best prediction of people will watch the documentary completely.

what is 2(9n-1)+7n+6= -60
n = -2.56
Explanation:2(9n-1)+7n+6= -60
The first thing we do is expand the parenthesis:
2× 9n - 2×1 + 7n + 6 = -60
18n -2 + 7n + 6 = -60
collect like terms:
18n + 7n -2 + 6 = -60
25n + 4 = -60
Subtract 4 from both sides:
25n + 4 -4 = -60 - 4
25n + 0 = -64
25n = -64
divide both sides by 25:
25n/25 = -64/25

Give a Θ estimate of the number of addition operations that the following algorithm will execute: i←1 t←0 while (i≤n) t←t+i i←i+
The estimate of the number of addition operations that the algorithm will execute is:
Θ(2n).
What is the complexity of the given algorithm?The complexity of the given algorithm is an estimate of the number of operations that the algorithm will execute.
For an algorithm bounded by a loop such as this one, due to the command while (i≤n), the length of the loop is bound of the complexity of the algorithm, hence we can begin the complexity equation as follows:
Θ(n).
Inside the loop, for each iteration of the loop, that is, each value of i, two addition operations are made, adding i to t and incrementing the count control variable i by 1.
Due to the two addition operations inside on each iteration of the loop, 2 is multiplied inside the complexity, hence the estimate of the number of addition operations that the algorithm will execute is:
Θ(2n).

Suppose that the function g is defined, for all real numbers, as follows.
Find g (-2), g (1), and g (4).
The values of the functions, when g is defined for all real numbers is as follows:
g(-2) = -3
g(1) = 3
g(4) = 0
Given, the function g is defined for all real numbers.
g(x) = { 1x²/4 - 4 if x≠1
3 if x=1 }
g(-2):
here, x = -2
where x ≠ 1
therefore, g(-2) = 1x²/4 - 4
substitute x as -2
g(-2) = 1(-2)²/4 - 4
g(-2) = 4/4 - 4
g(-2) = 1 - 4
g(-2) = -3
g(1):
here, x = 1
where x = 1
therefore, g(1) = 3
g(4):
here, x = 4
where x ≠ 1
therefore, g(4) = 1x²/4 - 4
substitute x as 4
g(4) = 1(4)²/4 - 4
g(-2) = 16/4 - 4
g(-2) = 4 - 4
g(-2) = 0
Hence we get the values of g(-2), g(1) and g(4) as -3,3 and 0 respectively.

What is data?
A set of discrete values called data is a collection of information that can describe amount, quality, fact, statistics, or just a series of symbols that can be further understood. A datum is a distinct state inside a collection of data. Typically, data is arranged into structures like tables that provide it additional context and meaning and can also be used as their own form of data in bigger structures. It's possible to use data as variables in a computation. Data can reflect both actual measures and abstract concepts. Data is employed often in practically every aspect of human organizational activity, including business and science. Stock prices, crime rates, unemployment rates, literacy rates, and census statistics are a few examples of data sets.
Companies sometimes gather data on customer web usage and preferences often without their consent. The main reason behind this dat collection is to suggest the best product or to show best advertisement based on the web usage and preferences.

Please provide working out for a and b. Thanks.
a) 102 is the smallest of the dropdown number
b) 1025 is the smallest dropdown number
c) 9874 is the largest 4-digit dropdown number
Explanation:Given:
All digits in a dropdown number are different and one of its digits is the average of all its digits.
It has at least two digits.
To find:
a) the smallest dropdown number
b) the smallest and largest 4-digit dropdown numbers
a) From the information given, the numbers are at least two digits. This means the smallest of the digits from the dropdown is 2
We can't have 0 as the starting number because it will reduce the digits by 1. The list will start from the smallest to the highest since we are looking for the smallest number.
For two digits: 12, 13, 14, etc
We can only have a 2-digit number whose average is part of digits if the numbers are the same digit.
As a result, we will move to 3 digits.
For 3 dgits: 102, 103, 104, 105, etc
We will check if any of the above will have one of its digits as average
102: 1 + 0 + 2 = 3
Average = 3/3 = 1
One of the digits of this number is the average of the number.
Hence, 102 is the smallest of the dropdown number
b) To get the smallest 4 digit dropdown number, we will list from smallest to highest
For 4 digits: 1023, 1024, 1025, 1026, 1027, ...
We will check if any of the above will have one of its digits as average
1023: 1+0+2+3 = 6
Average = 6/4 = 1.5
1024: 1+0+2+4 = 7
Average = 7/4 = 1.75
1025: 1+0+2+5 = 8
Average = 8/4 = 2
One of the digits of this number is the average of the number.
Hence, 1025 is the smallest dropdown number
To get the largest 4-digit dropdown number, we will list from largest to smallest
For 4 digits: 9876, 9875, 9874, 9873, 9872, etc
We will check if any of the above will have one of its digits as average
9876: 9+8+7+6 = 30
Average = 30/4 = 7.5
9875: 9+8+7+5 = 29
Average = 29/4 = 7.25
9874: 9+8+7+4 = 28
Average = 28/4 = 7
One of the digits of this number is the average of the number.
Hence, 9874 is the largest 4-digit dropdown number

By evaluating the square root function in x = 0 and x = 25/16 we will get:
f(0) = 0
f(25/16) = 5/4
How to evaluate the function?Here we have the square root function:
f(x) = √x
And we want to evaluate this in x = 0 and x = 25/16.
Evaluating in zero we get the same than you got:
f(0) =√0 = 0
Evaluating in x = 25/16 we will get:
f(25/16) = √(25/16)
Remember that the square root can be distributed under division, so:
√(25/16) = √(25)/√(16)
Now, we know that:
√25 = 5
√16 = 4
Then we can rewrite the quotient as:
√(25)/√(16) = 5/4
so f(25/16) = 5/4.
