The root domain in the DNS system of the Internet is a domain that is indicated by an empty name (i.e., containing no characters).
Each domain is split from the next when you enter a domain name, and there may also be a dot at the end of the name to demarcate the empty name for the root domain. If this dot is present and in its proper location, such as "www.example.com," the domain name is regarded as full (absolute). The name is regarded as relative if there isn't a dot at the end ("www.example" or "www.example.com").
Even if the phrase "root domain" was frequently used, the primary domain name of the website is the one that must be purchased or registered with a TLD extension.

The above table of values mean that the x values are
x = -1, 0 and 1
Substitute x = -1, 0 and 1 in the equation y = -3x - 4
So, we have the following representation
When x = -1
y = -3(-1) - 4 = -1
When x = 0
y = -3(0) - 4 = -4
When x = 1
y = -3(1) - 4 = -7

1) The estimated probability of patrick flipping a head with his coin is; 0.45
2) The margin of error for Patrick's estimated probability is; 0.218
3) The confidence interval for the chance of flipping a head with his coin is; CI = (0.232, 0.668)
No, the 95% confidence interval does not contain 50% as a probability, so it will be illogical to think that Patrick's lucky coin has a probability different from 0.5
How to find the confidence interval for proportions?We are given;
Number of trials; n = 20
Number of successful outcomes; x = 9
Thus; Proportion; p^ = x/n = 0.45
Now, the formula for the confidence interval of proportions is;
CI = p^ ± z√(p^(1 - p^)/n)
where;
z√(p^(1 - p^)/n) is margin of error
1) Probability of Patrick flipping a head with his lucky coin is;
p^ = x/n = 9/20 = 0.45
2) The margin of error is from the formula;
z√(p^(1 - p^)/n)
z for 95% confidence level is 1.96. Thus'
E = 1.96√(0.45(1 - 0.45)/20)
E = 0.218

A sample of bacteria is decaying according to a half-life model. If the sample begins with 700 bacteria, and after 13 minutes there are 630 bacteria, after how many minutes will there be 20 bacteria remaining?
When solving this problem, round the value of k to four decimal places and round your final answer to the nearest whole number
The number of minutes for 20 bacteria be left is 439minutes. The decay constant is 0.0081
What is exponential function?An exponential function is a mathematical function, which is used in many real-world situations. It is mainly used to find the exponential decay or exponential growth or to compute investments, model populations and so on.
The No of bacteria left at a particular time t is given as N(t)= Noe^-kt
where No= initial number of bacteria
k= decay constant and t = time
after 13 minutes
630= 700e^-13k
divide both sides by 700
630/700= e^-13k
0.9= e^-13k
ln0.9= -13k
k= ln0.9/-13 = -0.1054/-13 = 0.0081
time for 20 bacteria to be left =
20= 700e^-0.0081t
= 20/700=e^-0.0081t
0.0286= e^-0.0081t
ln0.0286= -0.0081t
-3.554= -0.0081t
divide both sides by -0.0081
t= -3.554/-0.0081= 439 minutes ( nearest minutes)

The difference between their average hiking rates is 0.51 miles/hour.
Given that, it took Lannie 1.9 hours to hike Ranger Cove Trail. It took Ava 4 hours to hike Mohawk Trail.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Using speed =Distance/Time
Here, Ranger Cove distance =4.8 miles and time =1.9 hours
Now, rate =4.2/1.9

Determine the rate of change.
The rate of change of the table is -500
How to determine the average rate of changeThe average rate of change of a function, graph, table or ordered pair is simply the slope of the relation
The function is represented by the table of values
The interval of the function are the x values
So, we make use of x values
x = 0 and x = 2
Start by calculating f(0) and f(2)
From the table, we have
f(0) = 30000
f(2) = 29000
So, the average rate over these intervals is calculated as:
Average rate = [f(2) - f(0)]/[2 - 0]
Substitute known values
Average rate = [30000 - 29000]/[0 - 2]

A rectangular yard measuring 35 ft by 55 ft is bordered (and surrounded) by a fence. Inside, a walk that is 3 ft wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.
The area of walk is 504 square feet
Area of rectangleThe area of rectangle is define as a product of length L and width w
calculate the area of rectangle yard
Area = L x W,
where A equal the Area, L equals the length and W equal width.
A = 35 x 55
A= 1925 square feet
Area of the rectangular yard is 1925 square feet
From the question, we have 3ft wide goes all the way along the fence inside.
Therefore, we subtract six feet from each of the value of length ( 35) and width (55) because each side has 3feet .
Area = L x W
A = 29 x 49
A = 1421 square feet
Area of new rectangle formed by allowing for three foot walk is 1421 square feet
Area of Walk
To get the area walk; we subtract area of new rectangular formed from area of rectangular yard
Area of Walk = Area of Rectangular yard - Area of new rectangle
Area of Walk = 1925 - 1421
Area of Walk = 504 square feet.

The graph of a piecewise function, f(x), is depicted above. Find its equation:
The function of piecewise graph shown in the figure is,
f(x) = {y = 6 for x < -5
{ [tex]y = -\frac{19}{9}x-\frac{5}{9}[/tex] for -5 ≤x < 5
{ y = 8/5x -14 for x ≥ 5
What is piecewise function?
A piecewise-defined function in mathematics is a function with several sub functions, each of which has a certain interval in the domain for which it is applicable. Piecewise definition is a method of expressing the function, not a property of the function.
From graph we can see that the first function is a line y = 6
Hence, f(x) = {y = 6 for x < -5}
Now to find the equation of second function.
From graph we get two points (-5, 10) and (4, -9).
First to find the slope
[tex]m = \frac{-9-10}{4+5} = \frac{-19}{9}[/tex]
Now to find the equation of line, using slope point form
[tex]y - 10 = \frac{-19}{9} (x-(-5))\\y-10=-\frac{19}{9}x-\frac{95}{9} \\ y=-\frac{19}{9}x-\frac{95}{9} + 10\\y = -\frac{19}{9}x -\frac{5}{9}[/tex]
So, f(x) = { [tex]y= -\frac{19}{9}x-\frac{9}{5}[/tex], for -5 ≤ x < 5}
Now to find the equation of third line.
From graph we get two points (5, -6) and (10, 2).
First to find the slope of the line
[tex]m = \frac{2-(-6)}{10-5} = \frac{8}{5}[/tex]
Now to find the equation of line, using slope point form
[tex]y-(-6)=\frac{8}{5}(x-5)\\ y+6=\frac{8}{5}x-8\\ y = \frac{8}{5}x - 14[/tex]
So, f(x) = {[tex]y = \frac{8}{5}x-14[/tex], for x ≥ 5}.

Cindy is attempting to calculate how much her car payment would be for a car that costs $27,000 to be repaid with monthly payments in 4 years at 4% APR.
Cindy's monthly payment of $609.63 will cost her $29,262.24 in 4 years at a 4% APR.
How is the total cost determined?The total cost that Cindy will spend on the car which costs $27,000 is computed by multiplying the monthly payment by 48 months (the payment period).
The monthly payment can be determined using an online finance calculator that compounds the interest rate monthly for four years.
Cost of car = $27,000
Annual Percentage Rate (APR) = 4%
Payment period = 4 years (monthly)
N (# of periods) = 48 months (4 years x 12)
I/Y (Interest per year) = 4%
PV (Present Value) = $27,000
FV (Future Value) = $0
Results:
PMT = $609.63
Sum of all periodic payments = $29,262.24
Total Interest = $2,262.45
Thus, Cindy will spend $29,262.24 for a car that costs $27,000, if she repays monthly for 4 years.
