Answer:
Step-by-step explanation:
The number of ways to arrange the letters in "HEDGEHOG" is 8!/(2!3!). The exclamation mark (!) means factorial, which is the product of all positive integers up to that number. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
In this case, we have two H's and three E's, so we have to divide the total number of arrangements by the number of arrangements of H's and the number of arrangements of E's to avoid overcounting.
The total number of arrangements of the eight letters is 8!:
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320
The number of arrangements of H's is 2!:
2! = 2 x 1 = 2
The number of arrangements of E's is 3!:
3! = 3 x 2 x 1 = 6
So the number of arrangements of the letters in "HEDGEHOG" that avoid overcounting is:
40320 / (2 x 6) = 40320 / 12 = 3360.
Therefore, there are 3360 ways to arrange the letters in "HEDGEHOG".

I need to know why the medians differ relative to the data set and the best measure of center?
Explanation:
In this case the median value is more representative of the 'center' of the population. The median is a better measure when the data set is skewed, has fat tails as compared to a normal didtribution, or has outliers. Otherwise you should use the arithmetic mean.
Which of the following is the midsegment for A ACE?
A. AC
B. BC
C. DB
D. CE
Explanation:
Points B and D are midpoints of segments AC and CE respectively. This is because of the tickmarks indicating congruent segment pieces (AB = BC and CD = DE)
Joining the midpoints together forms a midsegment. The midsegment is half as long as the side parallel to it. This means BD is half as long as AE. Flip things around to say that AE is twice as long as BD.

A circle graph was drawn from the data in the table. What percentage would be on the Decades slice of the circle graph?
24%
26.7%
86.4%
96%
Answer:
(a) 24%
Step-by-step explanation:
You want the percentage of people in the Decades slice of a circle graph if it represents 96 people. The other slices represent 128, 72, 52, 24, and 28 people.
PercentThe fraction in the second category is the ratio of the number in that category to the total number. The percent is the fraction multiplied by 100%.
96/(128 +96 +72 +52 +24 +28) × 100% = 96/400 × 100% = 24%
The Decades slice of the circle would be 24%, choice A.

of a group of 500 people, 60 are fit enough to climb Mount Shasta in California. The group has 300 women and 200 men. 12% of the men are fit
to climb the mountain. What is the probability that a person picked at random from the group is a male or is fit to climb Mount Shasta?
OA
OC
OD.
Answer as a fraction
Answer:
As a fraction, the probability that a person picked at random from the group is a male or is fit to climb Mount Shasta is 12/100.
Step-by-step explanation:
Let the number of fit men is x.
Now,
we know
x = 12% of 200 men
x = [tex]\frac{12}{100}[/tex] ×200
x = 0.12 × 200
= 24 men.
Given,
The 60 people are fit to climb the Mount Shasta ,24 of them are men,
so there must be
60 - 24 = 36 women who are fit to climb the mountain.
The probability of a person picked at random from the group is a male or is fit to climb Mount Shasta is the sum total of the probability of picking a fit male and the probability of picking a fit female is,
P(male or fit) = P(male and fit) + P(female and fit)
P(male or fit) = P(male) × P(fit | male) + P(female) × P(fit | female)
P(male or fit) = ([tex]\frac{200}{500}[/tex]) ×([tex]\frac{24}{200}[/tex]) + ([tex]\frac{300}{500}[/tex]) × ([tex]\frac{36}{300}[/tex])
=.4 × .12 + .6 × .12
= 0.048 + 0.072
=.12
So,
P(male or fit) ≈ 0.12
As a fraction, the probability that a person picked at random from the group is a male or is fit to climb Mount Shasta is 12/100.
In ΔGHI, i = 800 cm, m m∠G=26° and m m∠H=122°. Find the length of h, to the nearest 10th of a centimeter.
Answer:
For the nearest 10th of a centimeter, the value of h is 460 cm
Step-by-step explanation:
To find length of h we can use Law of Sines . The Law states that for a triangle with sides a, b, and c and angles A, B, and C opposite to those sides, the following equation holds:
a/sin A = b/sin B = c/sin C
In ΔGHI, let h be the length of the side opposite angle H, and let i be the length of the side opposite angle I.
Now:
h/sin 122° = i/sin 26°
We can find h by cross multiplying:
h = i * sin 122° / sin 26°
=459.9
Here,
h = 459.9 cm
By taking approximation we get 460 cm

A rectangular garden 12 feet by 16 feet has a stone path along the perimeter with the same width, w. The area of the garden and path is 420 square feet.
The correct equation to find the width, w, of the stone path would be: Option B. (2w+12) (2w+16) = 420
This is because the area of the garden and path is equal to the area of the rectangle with dimensions (12+2w) and (16+2w). Therefore, we can set up the equation:
(12+2w)(16+2w) = 420
Expanding and simplifying, we get:
4w² + 56w - 204 = 0
Dividing by 4, we get:
w² + 14w - 51 = 0
Factoring, we get:
(w+17)(w-3) = 0
Since the width of the path cannot be negative, the only valid solution is w = 3.

Answer:
48ft²
Step-by-step explanation:
Visualize the trapezoid as consisting of a rectangle with two triangles on either side. To find its total area, find the area of each and add them up.
Note that the formula for the area of a square is (base*height) and the formula for the area of a triangle is (0.5*base*height). The bottom of the trapezoid is 15ft and the top is 9ft, which makes the combined bases of the two triangles 15-9=6ft, meaning each triangle's base is 3ft.
Area of left triangle = 0.5*3*4 = 6ft²
Area of square = 4*9 = 36ft²
Area of right triangle = 0.5*3*4 = 6ft²
Therefore the total area is: 6ft² + 36ft² + 6ft² = 48ft²

Answer:
[tex]\textrm{Each side = 23.6893 cm}\\\\\\\textrm{Rounded to 2 decimal places = 23.69 cm}\\\\\textrm{Rounded to 1 decimal place = 23.7 cm}[/tex]
You can choose the level of precision as desired from the above
Step-by-step explanation:
The area of an equilateral triangle of side a
is
[tex]A = \dfrac{(a^2 \sqrt{3})}{4}[/tex]
We are given A = 243
Plugging in values we get
[tex]243 = \dfrac{a^2\sqrt{3}}{4}[/tex]
Switch sides so [tex]a^2[/tex] term is on the left
[tex]\dfrac{a^2\sqrt{3}}{4} = 243[/tex]
Multiply by 4 both sides to get rid of the denominator:
[tex]\dfrac{a^2\sqrt{3}}{4} \times 4 = 243 \times 4\\\\a^2\sqrt{3} = 972\\\\[/tex]
Divide by [tex]\sqrt{3}[/tex] both sides:
[tex]a^2 = \dfrac{972}{\sqrt{3}}\\\\a^2 = 561.18446\\\\a = \pm \sqrt{561.18446}\\\\[/tex]
Taking only positive square root:

Suppose that x and y vary inversely, and x = 10 when y = 8. Write the function that models the inverse variation.
If x and y vary inversely, we can write their relationship then the function that models the inverse variation is y = 80/x.
What is Function?
In mathematics, a function is a rule or mapping that associates each input value (also called the independent variable) with a unique output value (also called the dependent variable). Functions are often represented using an equation, formula, or a graph, and are used to model real-world phenomena and solve problems in various fields such as science, engineering, economics, and more.
They can take different forms and have different properties, such as being linear, quadratic, exponential, periodic, or more complex. Some common notation used to represent functions includes f(x), y = f(x), or simply y.
If x and y vary inversely, we can write their relationship as:
x * y = k
where k is a constant of proportionality. We can use the given initial values of x and y to solve for k:
10 * 8 = k
k = 80
