The method of calculating the area of a polygon depends on the type of polygon. Rectangles and triangles have straightforward calculations, however complex polygons might need to be divided into simpler figures. Certain figures such as circles and ellipses have unique formulas.
Explanation:Calculating the area of a polygon depends on the type of polygon. For simple regular polygons like a rectangle, area can be found by length x width, for triangles it's base x height / 2. In particular complex polygons, the shape might need to be divided into simpler shapes, and the areas calculated separately.
For a circle, the area A = πr², where r is the radius. If you're trying to find the area of an ellipse, it can be calculated by A = πab, with a and b being half the long and short axis respectively.
The process to determine the area of a frequency polygon is little complex. First, the range of each class interval must be determined, and then multiplied by the frequency of that interval, with these values then being added together.

To find the area of a polygon, you can divide it into smaller shapes with known area and add them up. Alternatively, you can use the formula for the area of a regular polygon.
Explanation:To find the area of a polygon, you can use different formulas depending on the type of polygon. One general method is to divide the polygon into smaller shapes whose area you know how to calculate, such as triangles or rectangles, and then add up the areas of those shapes. For example, to find the area of a rectangle, you multiply its length by its width.
Another method is to use the formula for the area of a regular polygon, which is given by the formula: Area = 1/2 * ap, where 'a' is the apothem (the distance from the center of the polygon to the middle of one of its sides) and 'p' is the perimeter of the polygon.

A multiple choice test has five questions each with 5 possible answers. Find the probability of guessing the correct answers to all of the questions
Answer:
5/25 or 1/5
Step-by-step explanation:
5 questions, each has 5 possible answers, 5x5=25 each question had 1 correct answer so 5 right answers in the whole test. 5/25 but if u need to simplify, 1/5
Answer: Probability of guessing all 5 correctly: 1/3125 = 0.032%
Step-by-step explanation:
Probability of guessing the first question correctly: 1/5
For that 1/5 of the time when the first question has been guessed correctly, the second question could be guessed correctly 1/5 of the time. So the first two questions could be guessed correctly 1/5 × 1/5 = (1/5)^2 of the time.
Similarly the first three questions could be guessed correctly (1/5)^3 of the time.
and the first four, 1/5)^4 of the time;
and all fives,
(1/5)^5 of the time.
(1/5)^5 = 1/3125 = 0.00032 = 0.032%

The perimeter of the rectangular state is 42 miles . A ranger estimates that there are 9 deer in each square mile of the park . If this estimates is correct ,how many total deer are in the park ,explain your answer using numbers ,symbols, and words
P.S this questions is important ,so answer it fast
Thank you
Answer:
990 deers is ONE possible answer.
Step-by-step explanation:
Since we don't know anything else than the perimeter, we don't know the exact dimensions of the park.
For example, it could be 10 x 11 miles, perimeter is 42, but the area is 110 sq miles.
It could also be 9 x 12 miles, perimeter is again 42, but the area is now 110 sq miles.
It could be a 1 x 20 miles park, perimeter is again 42, but the area is just 20 sq miles.
And it could be many other dimensions scenarios. That affect of course the calculation result.
For this answer, I'll assume the park is 10x11 miles, for an area of 110 sq miles.
Since the estimation is that there's 9 deeps for square mile... that means that for a park measuring 10x11 miles, there would be 990 deers (9 * 110).
This has to do with mean,median,mode, and all that stuff, but my teacher is like,not really good at explaining stuff lol

Hobby Shop is selling model cars and model trucks for 50% off this week. At the sale price, you can buy one car and one truck for $13.00. Also at the sale price, you can buy 4 trucks and 2 cars for $42.00. What is the sale price and the original price of the model car and the model truck?
Answer:
The truck original price is $16.00 and the car price is $5.00.
The truck sale price is $8.00 and the car price is $10.00.
Step-by-step explanation:
We need to find the original price of the truck (T) and car (C)
Sale price of the truck is 50% so that means it is half the original price.
Now let's see the equations we can come up with there:
At sale price:
[tex]T + C = \$13.00\\\\4T + 2C = \$42.00[/tex]
We can solve this through substitution.
Using the first equation, we can come up with an equation for one of the missing variables.
[tex]T + C =\$13.00\\\\C = \$13.00 - T[/tex]
We can use this equation on the second one, to solve for one variable. [tex]4T + 2C = \$42.00\\\\4T + 2(\$13.00-T) = \$42.00\\\\4T + \$26.00 - 2T = \$42.00\\\\4T - 2T = \$42.00 - \$26.00\\\\2T = \$16.00\\\\\dfrac{2T}{2}=\dfrac{\$16.00}{2}\\\\T = \$8.00[/tex]
The sale price of the model truck is $8.00.
Now can use this on the first equation again.
[tex]T + C = \$13.00\\\\\$8.00 + C = \$13.00\\\\C = \$13.00 - \$8.00\\\\C = \$5.00[/tex]
The sale price of the model car is $5.00.
Because it is 50% off on both models, the original price is twice the sale price. So we can solve it by multiplying the sale prices by 2.
Original price of model truck: $8.00 x 2 = $16.00
Original price of model car: $5.00 x 2 = $10.00
Answer:
The truck's original is $16. The sale price is $8. The car's original is $10. It's sale is $5.

solve for x.
9(x - 6) = 8(x + 6)
Answer:
x=102
Step-by-step explanation:
9x-54=8x+48
subtract 8x from both sides
x-54=48
add 54 to both sides
x=102
Answer:
x = 102
Step-by-step explanation:
9(x + -6) = 8(x + 6)
Reorder the terms:
9(-6 + x) = 8(x + 6)
(-6 * 9 + x * 9) = 8(x + 6)
(-54 + 9x) = 8(x + 6)
Reorder the terms:
-54 + 9x = 8(6 + x)
-54 + 9x = (6 * 8 + x * 8)
-54 + 9x = (48 + 8x)
Solving
-54 + 9x = 48 + 8x
Add '-8x' to each side of the equation.
-54 + 9x + -8x = 48 + 8x + -8x
Combine like terms: 9x + -8x = 1x
-54 + 1x = 48 + 8x + -8x
Combine like terms: 8x + -8x = 0
-54 + 1x = 48 + 0
-54 + 1x = 48
Add '54' to each side of the equation.
-54 + 54 + 1x = 48 + 54
Combine like terms: -54 + 54 = 0
0 + 1x = 48 + 54
1x = 48 + 54
Combine like terms: 48 + 54 = 102
1x = 102
Divide each side by '1'.
x = 102
Chef Katrina uses 1 cup of pecans for every 3 cups of peanuts in her Merry Munch Mix. One cup of pecans costs $ 4.99 and one cup of peanuts costs $2.25. If the cost for nuts in a batch of Merry Munch Mix is $35.22, how many cups of each type of nut were used?
Final answer:
Chef Katrina used 3 cups of pecans and 9 cups of peanuts for her Merry Munch Mix, totaling $35.22 based on the given prices of $4.99 per cup of pecans and $2.25 per cup of peanuts.
Explanation:
Calculating the Quantities of Pecans and Peanuts in the Merry Munch Mix
Chef Katrina uses a ratio of 1 cup of pecans to 3 cups of peanuts in her mix. We are given the cost per cup of pecans as $4.99 and the cost per cup of peanuts as $2.25. The total cost of nuts in the mix is $35.22.
To solve this, let's denote the number of cups of pecans used as p and the number of cups of peanuts as 3p (since there are three times as many peanuts as pecans). The total cost for pecans would be p times $4.99 and for peanuts 3p times $2.25.
Our equation based on the total cost is:
4.99p + 2.25(3p) = 35.22
4.99p + 6.75p = 35.22
11.74p = 35.22
Dividing both sides by 11.74 to solve for p:
p = 35.22 / 11.74
p = 3 cups of pecans
As there are three times more peanuts than pecans:
3p = 3 * 3 = 9 cups of peanuts
Therefore, Chef Katrina used 3 cups of pecans and 9 cups of peanuts in her Merry Munch Mix.

The regular price of a television set is $1,200. Albert buys the television set at a discount of 35% . How much does he pay for the television set?
He pays $780 for the television set.
1200*.35=420
1200-420=780
Albert pays $780 for the television set after receiving a 35% discount on the original price of $1,200.
The regular price of a television set is $1,200. To calculate the price Albert would pay after receiving a 35% discount, you need to calculate the discount amount and subtract it from the original price. The discount can be calculated by multiplying the original price by the discount percentage.
Discount = Original Price × Discount Percentage = $1,200 ×0.35 = $420
Now subtract the discount from the original price:
Final Price = Original Price - Discount = $1,200 - $420 = $780
Therefore, Albert pays $780 for the television set.
Campbell's is designing a new label for their soup cans that covers the entire side of the can The soup can has a height of 8 inches and a radius of 2.5 inches. Determine how much material is needed to create each label.
Answer:
When π is approximated, 125.68, or 40π
Step-by-step explanation:
Circumference formula is 2πr
This is approx: 15.71
Multiply that by 8 to find the surface area of the side of the can.
The answer is 125.68.
HOWEVER, if you are expressing this without approximating π,
it would be 5(Pi), then multiply by 8, and we would get 40π
So un-simplified is 40π
Final answer:
The amount of material needed to create each label for Campbell's soup cans is 40π square inches.
Explanation:
To determine the amount of material needed to create each label for Campbell's soup cans, we need to find the lateral surface area of the can. The lateral surface area is the area of the curved surface. Assuming the label covers the entire side of the can, we need to find the area of the curved surface which can be calculated using the formula:
Lateral Surface Area = 2 * π * radius * height
Substituting the given values, we have:
Lateral Surface Area = 2 * π * 2.5 * 8 = 40π square inches.

if the mean of a normal distribution is 22, what is the median of the distribution?
Answer:
22
Step-by-step explanation:
Normal Distributions are the most important in statistics. They are also know as "bell curves".
There are special properties of Normal Distributions. I name 3 of them below:
1. Normal distributions are symmetric about their mean.
2. The area under the normal curve is 1
3. The mean, mode, and median of normal distribution are equal
This question can easily be solved using property #3 in the stated above properties.
The mean and median of normal distribution are equal. Since mean is given as 22, the median will also be 22.
