So the average decrease will be 50% for the season of 5 weeks as the definition of percent decrease will be "The difference between starting and ending values is the percentage decrease. It displays a percentage loss of value compared to the original regardless of the units. The difference between the initial and final amounts is the amount of decrease".
What is percent decrease?The difference between starting and ending values is the percentage decrease. It displays a percentage loss of value compared to the original regardless of the units. The difference between the initial and final amounts is the amount of decrease.
Here,
The percent decrease will be,
48000-24000=24000
24000/48000*100=50%
24000-12000=12000
12000/24000*100=50%
12000-6000=6000
6000/12000*100=50%
6000-3000=3000
3000/6000*100=50%
3000-1500=1500
1500/3000*100=50%
Due to the definition of percent decrease being a season of five weeks, the average decrease will be 50% "The percentage decrease is the difference between the starting and ending values. Regardless of the units, it shows a percentage decline in value relative to the starting point. The amount of decrease is the difference between the initial and final amounts ".

A card is chosen at random from a deck of 28 cards. The deck contains red, 12 black 7 blue, and 2 green cards. Thend the card is returned to the deck and New card is cosen. the table below shows the results of choosing 14 cards. for which color of card is the experimental probability the same as the theoretical probabicaras.Results red= 10 black=2 blue=1green=1
Answers
From the question, we can find that we have 7 red cards
so, the probability of chosen at random a card is
p(red)= 7/28
p(black)= 12/28
p(blue) = 7/28
p(green)=2/28
As after picking a card we return the card to the deck, and given that we chose 14 cards, our theoretical number of chosen cards should be around
p(red) = (7/28)x14 = 3.5
p(black) = (12/28)x14 = 6
p(blue) = (7/28)x14 = 3.5
p(green)= (2/28)x14=1
so the color that the experimental probability is the same as the theoretical probability is green

Combining similar terms:
21x - 28 = (6x + 3x) + (-4 +12)
21x - 28 = 9x + 8
9x is adding on the right, then it will subtract on the left
28 is subtracting on the left, then it will add on the right

In all cases use the following formula for the are of a rectangular shape:
A = lw
Plot A:
The area and height are known, then, solve the formula for the length l:
l = A/w
repace the given values
l = (204 ft²)/(10.2 ft)
I = 20 ft
For the perimeter you have:
P = 2l + 2w = 2(20 ft) + 2(10.2 ft) = 60.4ft
Plot B:
The length and the perimeter are known. For the expression for the perimeter solve for w:
P = 2l + 2w
w = (P - 2l)/2
replace the values of P and l:
w = (57.56 ft - 2(12.78 ft))/2 = 16 ft
Then, replace in the formula for the area:
A = lw = (12.78 ft)(16 ft) = 204.48 ft²
Plot C:
The area and the height are known. Use the formula for A to obtain the length:
l = A/w = 204.49 ft/14.3 ft = 14.3 ft
and for the perimeter:
P = 2w + 2l = 2(14.3 ft) + 2(14.3 ft) = 57.2 ft
Hence, you can conclude:
- The plost with the least amount of fencing is the plot with the lowest perimeter, hence, Plot C requires the least amount of fencing.
- The plot with the greatest area is Plot A.
given the parent function f(x)=ab^x how could changing from a 2 to -2 cause f(x) to change? use words like "increasing" "decreasing" "positive" "negative" "domain" and "range" to describe the similarities and differences in the graph
Answers
Here, we want to get the response of the given function with respect to the change in the value of the leading coefficient
As we can see from the question, what we have is an example of an exponential function
Generally, with exponential function with a positive value for a, as the value of x moves closer to negative infinity, we have that the value of f(x) moves closer to 0. What this mean is that with a decrease in the value of x, the value of f(x) moves closer to 0
Hence, as the domain value moves closer to negative infinity, the value of the range moves closer to 0. Furthermore, as the value of the domain moves closer to positive infinity, the value of the range also close in on positive infinity
The above situation is for a being positive (given as 2)
Now, when a becomes negative, we have an opposite direction for the plot
Although, as the domain value moves closer to negative infinity, we have the value of f(x) being closer to zero. This is directly as above
However, as the domain moves towards positive infinity, the value of the range moves closer to negative infinity
In summary;
[tex]\begin{gathered} \text{for a = 2} \\ x\Rightarrow\text{ +}\infty\text{ , f(x)}\Rightarrow+\infty \\ x\Rightarrow-\infty,\text{ f(x) }\Rightarrow0 \\ \text{for a = -2} \\ x\Rightarrow+\infty,\text{ f(x)}\Rightarrow-\infty \\ x\Rightarrow-\infty,\text{ f(x)}\Rightarrow0 \end{gathered}[/tex]find the solution to the system of equations given below x=-4 5x+4y=-16

The score that cutt off the middle 50 percent of all scores is 43.2
Explanations:For a normal distribution, the normal value is the mean
It divides the curve in 50%-50%
Mean score, μ = 43.2
Standard Deviation, σ = 8.6
P(X≤a)=0.5
Use Z =(X-μ)/δ ~N(0;1)
b =(a-μ)/σ
P(Z≤b)=0.5
The value is b=0 (the mean for Z)
a=(b*σ)+μ

Fibonacci, Pythagoras and Descartes went out for breakfast. The total bill was $38.50. The tax rate was 7% and they left a 20% tip. Determine the total bill. Round to the nearest hundredth.so how much will each person pay if the bill was equally divided?
Answers
Given:
• Total bill = $38.50
,• Tax rate = 7% = 0.07
,• Tip = 20% = 0.20
Let's find the total bill after tax and tip.
Now, to find the total bill we have:
Total bill = bill + tax amount + tip amount
Where:
[tex]\begin{gathered} \text{ tax amount = 0.07}\times38.50=2.695 \\ \\ Tip\text{ amount = 0.20 }\times38.50=7.7 \end{gathered}[/tex]The tax amount is $2.695
The tip amount is $7.70
Now, to find the total bill, we have:
Total bill = $38.50 + $2.695 + $7.7 = $48.895 ≈ $48.90
Therefore, the total bill rounded to the nearest hundredth is $48.90
Part B.
To find the amount each person will pay if the bill was equally divided, let's divide the total bill by the number of people.
Where:
Number of people = 3
Hence, we have:
[tex]\frac{48.90}{3}=\text{ 16.30}[/tex]Therefore, the amount each person will pay is $16.30

For her phone service, Lucy pays a monthly fee of $15, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is$84.75What are the possible numbers of minutes she has used her phone in a month?Use m for the number of minutes, and solve your inequality for m.
Answers
m ≥ 1395 minutes
Explanation:Monthly fee = $15
fee paid per minute of use = $0.05
let the number of minutes she used = m
The least amount she has been charged = $84.75
least is written as ≥ $84.75
The equation:
Monthly fee + fee per minute(number of minutes) = The total charge
The equal sign changed below since the question mentioned the least amount
$15 + 0.05(m) ≥ $84.75
15 + 0.05m ≥ 84.75
To get the possible number of minutes, we will solve for m:
15 + 0.05m ≥ 84.75
subtract 15 from both sides:
0.05m ≥ 84.75 - 15
0.05m ≥ 69.75
divide both sides by 0.05:
m ≥ 69.75/0.05
m ≥ 1395 minutes
The possible number of minutes she has used her phone in a month is at least 1395 minutes
Why aren't there infinitely many semi-regular tessellations?
Answers
Regular tessellations use identical regular polygons to fill the plane. The polygons must line up vertex to vertex, edge to edge, leaving no gaps.
Semi-regular tessellations have two properties:
• They are formed by two or more types of regular polygon, each with the same side length
,• Each vertex has the same pattern of polygons around it.
There are 8 semi-regular tessellations in total. We know each is correct because again, the internal angle of these shapes add up to 360.
For example, for triangles and squares, 60 × 3 + 90 × 2 = 360.

she will need to start the mower more than 10 times.There are just two possible results for each pull. The lawnmower either starts or it doesn't. The binomial distribution is employed to answer this question since the likelihood that the mower will start on a pull is independent of all other pulls.Binomial distribution of probabilitiesThe conditions are: x is the total number of victories.The number of trials is n.P represents the likelihood that a trial will be successful.It has a 20% chance of starting on any given pull, therefore
Item
a:This probability is P(X = 0) when n = 2, multiplied by 0.2, which is the probability that it starts on the third, and it is that it doesn't start on the first two. Hence:
It has a 0.128 = 12.8% chance that she starts the mower with exactly 3 pulls.
Item b:When n = 10, this probability is none on the first 10 and is hence P(X = 0):
Her chances of needing more than 10 pushes to start the mower are 0.1074, or 10.74%.
It has a 0.128 = 12.8% chance that she starts the mower with exactly 3 pulls.
Item b:On the first, there is no chance in this.

a. 863.08 ft²
b. 474 ft²
c. 249 ft²
d. $4,259.24
EXPLANATION
Given:
• Rooms with ,carpet,: Family room and living room
,• Rooms with ,hardwood,: kitchen and foyer
,• Rooms with ,tiles,: breakfast nook and mudroom
• Cost ,carpet,: $1.80 per square foot
,• Cost ,hardwood,: $4.50 per square foot
,• Cost ,tiles,: $2.30 per square foot
First, we have to find the area of each of the mentioned rooms,
a. The family room is in the shape of a square whose sides are all 20 feet and a semicircle whose diameter is 20 feet. The area of the family room is the sum of the areas of each of these figures,
[tex]A_{family-room}=(20ft\cdot20ft)+(\frac{1}{2}\cdot\pi\cdot(20ft/2)^2)[/tex]As shown above, the area of the semicircle is half the area of the full circle with the same diameter. Solve,
[tex]A_{family-room}\approx(400ft^2)+(157.08ft^2)=557.08ft^2[/tex]The living room is in the shape of a rectangle with side lengths 15ft and 22ft, but a right triangle is cut out from the corner. The area of the living room is the area of the mentioned rectangle minus the area of the triangle of the corner,
The side lengths of the triangle are 15ft - 9ft = 6ft and 22ft - 14ft = 8ft. The area of the triangle is,
[tex]A_{triangle}=\frac{6ft\cdot8ft}{2}=24ft^2[/tex]So, the area of the living room is,
[tex]A_{living-room}=(22ft\cdot15ft)-24ft^2=330ft^2-24ft^2=306ft^2[/tex]The area that Rachel wants to cover with a new carpet is,
[tex]A_{carpet}=A_{family-room}+A_{living-room}=557.08ft^2+306ft^2=863.08ft^2[/tex]Hence, the area to be covered with carpet is 863.08 ft².
b. The kitchen is a rectangle with dimensions 24 ft and 15 ft, so its area is,
[tex]A_{kitchen}=24ft\cdot15ft=360ft^2[/tex]The foyer is in the shape of a rectangle with dimensions 10ft and 15ft. However, assuming that the stairs won't be covered with hardwood and that they cover that part of the foyer's floor, to find the area we have to subtract the area the stairs occupy in that room.
The rectangle where the stairs are has dimensions 9ft and (10ft - 6ft ) = 4ft. The area of the Foyer is,
[tex]A_{foyer}=(10ft\cdot15ft)-(9ft\cdot4ft)=(150ft^2)-(36ft^2)=114ft^2[/tex]The area Rachel wants to be covered by hardwood is the sum of the two,
[tex]A_{hardwood}=A_{kitchen}+A_{foyer}=360ft^2+114ft^2=474ft^2[/tex]Hence, the area to be covered with hardwood is 474 ft².
c. The mudroom is in the shape of a rectangle with dimensions 15 ft and 7 ft, so its area is,
[tex]A_{mudroom}=15ft\cdot7ft=105ft^2[/tex]The breakfast nook is in the shape of a trapezoid, where the height is 8ft and the lengths of the bases are 24ft and 12ft. Its area is,
[tex]A_{breakfast-nook}=\frac{(12ft+24ft)}{2}\cdot8ft=\frac{36ft}{2}\cdot8ft=18ft\cdot8ft=144ft^2[/tex]The area Rachel wants to cover with tiles is the sum of these two areas,
[tex]A_{tiles}=A_{mudroom}+A_{breakfast-nook}=105ft^2+144ft^2=249ft^2[/tex]Hence, the area to be covered with tiles is 249 ft².
d. Finally, we have to find the cost of flooring with each material,
[tex]Costs=\begin{cases}C_{carpet}=A_{carpet}\cdot p_{carpet}=863.08ft^2\cdot1.80=1,553.54 \\ C_{hardwood}=A_{hardwood}\cdot p_{hardwood}=474ft^2\cdot4.50=2,133 \\ C_{tiles}=A_{tiles}\cdot p_{tiles}=249ft^2\cdot2.30=572.70\end{cases}[/tex]The total cost of the project is the sum of the three,
[tex]C_{project}=C_{carpet}+C_{hardwood}+C_{tiles}=1,553.54+2,133+572.70=4,259.24[/tex]Hence, the total cost of the re-flooring project will be $4,259.24.
Dilate the figure by the scale factor. Then enterthe new coordinates.A(-1,1)B(4,0)K=5A'( [?],[])B'( 1 )C'([ ],[]).C(1,-3)EnterAnswer
Answers
A dilation is a proportional stretch or shrink of an image based on a scale factor. It is represented by:
[tex](x,y)\rightarrow(K\cdot x,\text{ K}\cdot y)[/tex]Then, for the figure on the question tab and scale factor of 5:
[tex]A(-1,1)\rightarrow A^{\prime}(-1\cdot5,1\cdot5)=A^{\prime}(-5,\text{ 5)}[/tex][tex]B(4,0)\rightarrow B^{\prime}(4\cdot5,0\cdot5)=B^{\prime}(20,0)[/tex][tex]C(1,-3)\rightarrow C^{\prime}(1\cdot5,-3\cdot5)=C^{\prime}(5,-15)[/tex]Eric needs to manufacture a turntable with a circumference of `140pi` centimeters.

The correct option is C 5/(2π) . The ideal radius must he control the radius of the turntable will be 5/(2π) .
What is meant by circumference?circle's circumference 22 inches around make up the circle. Periphery from the center to the sphere's circumference: 2: an object or figure's external boundary or surface The circumference, which in geometry refers to a circle or ellipse's perimeter, is derived from the Latin circumferens, which means "carrying around." In other words, the circumference would be the length of the circle's arc if it were opened out and straightened out to a line segment. Any great circle's circumference, or the distance between any two planes that cross a sphere's center, is measured in meters. Any large circle that traverses a pole-designated point is known as a meridian. The shortest path between any two locations on a sphere is referred to as a geodesic.
