Answer:
The polygon with the smallest perimeter is the megagon
The polygon with the largest perimeter is the triangle
Step-by-step explanation:
An equilateral triangle with area = 20 has
0.5× a²×sin60 = 20
a= 6.796
Hence, perimeter = 20.39
A square of area 20 has perimeter= 4×√20 = 17.9
A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05
Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases
Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.
Answer:
d. We are 95% sure that between 52% and 68% of all adults in this city will root for North High School.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
So the correct answer is:
d. We are 95% sure that between 52% and 68% of all adults in this city will root for North High School.
The function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)
<h3>How to determine the reflection?</h3>
The equation is given as:
f(x) = 2(0.35)^x
The reflection of a function over the y-axis is :
f'(x) = f(-x)
So, we have:
f(-x) = 2(0.35)^(-x)
From the list of options, we have
h(x) = 2(0.35)^(-x)
Hence, the function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)

The range is just the distance between the biggest number
and the smallest one.
The biggest number on that list is 350 .
The smallest number on that list is 75 .
The range is from 75 to 350, or a distance of 275 .
4/25 is already simplified
