can you explain to me what a voronoi diagram is?and what are the edges, and other things?
Answers
A Voronoi diagram is a division of a plane into areas near each of a given set of objects in mathematics. These things are just infinitely many points in the plane in the simplest scenario (called seeds, sites, or generators). There is a region, known as a Voronoi cell, for each seed that is made up of all points in the plane that are closer to that seed than to any other point. A set of points' Voronoi diagram and Delaunay triangulation are identical.
We are aware that any intersection of half-planes results in a convex region bordered by a collection of linked line segments. Voronoi edges are the line segments that define the limits of Voronoi regions. These edges' termini are known as Voronoi vertices.

Step-by-step explanation:
(e) Cards are 65p each and gift wrap
sheets are 45p each at a gift shop. Owen
buys 21 items from the shop and spends
£11.85. How many cards and how many
gift wrap sheets did Owen buy?
Answers
Owen bought 9 gift wrap sheets.
Given, Cards are 65p each and gift wrap sheets are 45p each at a gift shop.
Owen buys 21 items from the shop and spends £11.85.
Let the number of cards be x,
the number of gift wrap sheets be y
Now, according to question
x + y = 21
0.65x + 0.45y = 11.85
On multiplying the first equation by 0.45, we get
0.45x + 0.45y = 9.45
0.65x + 0.45y = 11.85
On subtracting, we get
0.2x = 2.4
x = 12
On solving, we get
12 + y = 21
y = 9
Hence, Owen bought 9 gift wrap sheets.

15)The demand equation for a certain product is given by the formulap = 32-10.0001x+1where x is the number of units sold in a month and p is the price perunit. If the price is set at $14.75 for the month, how many units will be sold?
Answers
The demand equation is given to be:
[tex]p=32-\sqrt{0.0001x+1}[/tex]where p is the price and x is the number of units sold.
If the price per unit is $14.75, the number of units will be calculated as follows:
[tex]\begin{gathered} p=14.75 \\ \therefore \\ 14.75=32-\sqrt{0.0001x+1} \end{gathered}[/tex]Subtracting 32 from both sides, we have:

Answers
The rule of the simple interest is
[tex]I=P\times R\times T[/tex]P is the initial amount
R is the rate in decimal
T is the time in years
Since Kim places $1250, then
P = 1250
Since the rate is 4.25%, then
[tex]R=\frac{4.25}{100}=0.0425[/tex]Since the time is 60 months, divide it by 12 to change it to years
[tex]\begin{gathered} T=\frac{60}{12} \\ T=5 \end{gathered}[/tex]Substitute them in the rule above

What is the probability that a randomly selected label produced by the company will contain a defective compact disk?.
Answers
The probability that a randomly selected label produced by the company will contain a defective compact disk is 0.034.
How to calculate the probability?In this, it should be noted that there are 3 possible cases in the chosen disc can be from any of the manufacturing companies, so the total probability will be the sum of probabilities of getting a faulty disc from companies 1-3.
The probability from company 1 will be;
= 0.03*0.36
The probability from company 2 will be:
= 0.04*0.52
The probability from company 3 will be:
= 0.02*0.12
The total probability will now be:= (0.36*0.03)+(0.04*0.52)+(0.02*0.12)

The Matthews’ family paid $265,000 when they bought their house in 2005. It is now worth $319,000. What is the percent increase on the price of the home?
Answers
The percent increase on the price of the home is 20.37%.
What is percent increase?
A percent increase refers to how much a percentage has gone up over time. In order to reach this number, you would need to find the difference between the original value and the final value, subtracting to find the exact total of the decrease.
Formula is given by
New number (value) – original number (value) = increase
Increase / original number (value) x 100 = percent increase
Given ,
initial value of home = $265,000
After few years, the value = $319,000
Increase = $319,000 - 265,000
=54000
Percent increase = 54000/265000× 100
= 20.37%

What is the probability that a child chosen at random from the nursery arrives by car?
Answers
Answer:
Will assume that there are 100 kids.
100 x 40% =40 of them are boys
40 x 70% = 28 boys arrive by car.
100 - 40 = 60 - Number of girls in Nursery.
60 x 60% = 36 of them arrive by car.
28 boys + 36 girls = 64 - kids that arrive by car.
64 / 100 = 64% - probability of a randomly picked kid that he/she arrived by car.
