A scientist evaluated the local deer population. The scientist found that there were 110 juveniles and 90 adults in the local population. What percentage of the deer were juveniles?
Answer:
55%
Step-by-step explanation:
To find the percentage of juveniles in the local deer population, we need to calculate the proportion of juveniles in the total population and convert it to a percentage.
First, find the total number of deer in the population by adding the number of juveniles and adults:
110 juveniles + 90 adults = 200 deer
Next, divide the number of juveniles by the total number of deer and multiply by 100 to convert to a percentage:
110 juveniles / 200 deer * 100 = 55%
Therefore, 55% of the local deer population were juveniles.

The factors of the quadratic function x² - 2x - 4 is equal to
(x + 1 + √5)(x - 1 + √5)
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, The zeros of the quadratic function x² - 2x - 4 are,
(1 + √5) and (1 - √5). (As they occur in conjugate pairs).
Therefore, The factors of (x + (1 + √5))(x + (x - (1 - √5))

Solve, for 0 ≤ x < 360°, the equation
5 sinx - 5 cosx = 2
In response to the query, x is equal to 60°, 120°, 240°, and 300°. These four options are the answer to the equation.
What does equation mean in its entirety?A mathematical equation is a statement that two amount or values are equal, such as 6 x 4 = 12 x 2. 2. A noun that counts. An equation is applied when several or more factors must be considered jointly in order to understand or explain the whole situation.
This equation can be solved using the trigonometric identity:
[tex]sinx = \sqrt{ (1 - cos^2x)}[/tex]
This identity can be used as a substitution in the equation:
5 sinx - 5 cosx = 2
5 [tex]\sqrt{(1 - cos^2x) }[/tex] - 5 cosx = 2
5 sqrt[tex](1 - cos^2x)[/tex]) = 7 + 5 cosx
Squaring both sides:
25([tex]1 - cos^2x[/tex]) = 49 + 70 cosx + 25 [tex]cos^2x[/tex]
25 - 25 [tex]cos^2x[/tex] = 49 + 70 cosx + 25 [tex]cos^2x[/tex]
0 = 74 + 45 cosx
45 cosx = -74
cosx = -74/45 = -2/3
The inverted cosine function can be used to determine that x = cos-1(-2/3). x must be within the range of 0° to 360°, hence x must be 300°.
5 sin - 5 cos - 5(-1/2) = 5 sqrt(3)/2 + 5/2 = 2 + 2.5 = 2.5
Since the left side of the equation is not equal to 2, x = 300° is not a solution to the equation.
We can repeat this process for the other solutions to the equation:
x = 60°, x = 120°, x = 240°, and x = 300°
These are the four solutions to the equation for 0° <= x < 360°.

Describe Function.The mathematics curriculum covers the study of numbers or rather their variations as well as in our environment, buildings, and both actual and imagined locations. A function presents a graph representation of the relationship between input and output quantities. A function, expression simply, is a collection of sources that, when combined, result in particular outputs by each input. There is a locale, territory, or range assigned to each job.
Here,
The rate of change of a linear function is the slope of the line.
Function A is y = 4x - 3, so the rate of change (slope) is 4.
To find the rate of change of function B, we can calculate the slope of the line passing through the points given in the table. Using the two points (1,4) and (5,12), we get:
slope = (change in y) / (change in x) = (12-4) / (5-1) = 2

Shannon put some money in her savings account. After 6 months, she earned $10.50 in interest. If the interest rate was 7%, how much money did Shannon put in her account?
The amount of money put by Shannon in her account is $300.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.
Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.
Given that Shannon put some money in her savings account. After 6 months, she earned $10.50 in interest. If the interest rate was 7%,
The amount will be calculated as:-
SI = ( P x R x T ) / 100
10.50 = ( P x 7 x 1 ) ( 2 x 100 )
P = ( 10.50 x 2 x 100 ) / ( 7 )
P = $300

Two houses are 1.5 inches apart on a map. The actual distance between the houses is 10.8 miles. What is the scale of the map?
Answer:
I inch = 7.2 miles
Step-by-step explanation:
Proportion method is applied:
1.5 inches on a map = 10.8 miles of actual distance
∴ 1 inches on the map = x miles of the actual distance
Cross-multiplication is applied:
(1.5 inches)(x miles) = (1 inch)(10.8 miles)
x needs to be isolated and made the subject of the equation:
x miles = [tex]\frac{(1 inch)(10.8 miles)}{1,5 inches}[/tex]
Inches in the numerator and denominator will cancel eachother out:
x miles = [tex]\frac{10.8 miles}{1.5}[/tex]
x miles = 7.2 miles
∴ Scale on the map:

suppose that x is a discrete random variable that takes integer values from 1 to 100 (both inclusive), and has cumulative distribution function (cdf)
The probability that the discrete random variable x takes a value less than or equal to 50 is 0.50, since F(50) = 50/100 = 0.50.
F(x) = x/100
Then, the probability that x takes a value less than or equal to 50 is 0.50, since
F(50) = 50/100 = 0.50
The cumulative distribution function (CDF) of a random variable is a function that gives the probability that the random variable is less than or equal to a certain value. In this case, the CDF of the random variable x is given by F(x) = x/100.
Therefore, to find the probability that x takes a value less than or equal to 50, we simply need to evaluate the CDF at x = 50. This is done by substituting 50 into the CDF, which gives us F(50) = 50/100 = 0.50. This means that the probability that x takes a value less than or equal to 50 is 0.50.

What is Disk method of integration?
Disc integration is a method for estimating the volume of a solid of revolution of a solid-state material when integrating along an axis "parallel" to the axis of revolution in integral calculus.
The volume of the solid can be found using the disk method of integration. In this method, we consider thin slices of the solid perpendicular to the x-axis, each of which is a disk with a square cross-section.
The volume of each slice is equal to the product of the area of its cross-section and its thickness, which is equal to the difference in x-coordinates between the top and bottom of the slice.
Let's call the top-right corner of the square cross-section (x, y, z). We k[tex]x^2 + y^2 = 256[/tex]
And we also know that the side length of the square is equal to 2y. So, the area of the cross-section is equal to [tex](2y)^2 = 4y^2.[/tex] The volume of the slice is equal to [tex]4y^2 dx.[/tex]
Since the semicircle is centered at the origin, the value of y ranges from 0 to 16.
The value of x ranges from 0 to the square root of [tex]256 - y^2.[/tex]Using these ranges, the volume of the solid can be calculated as follows:
[tex]V=\int\limits {[0,16] 4y^2 \sqrt{(256 - y^2)} } \, dy\\V= [0,16] \int\limits {4y^2 \sqrt{(256 - y^2)} } \, dy[/tex]
This is the integral that gives the volume of the solid.
Therefore, [tex]V= [0,16] \int\limits {4y^2 \sqrt{(256 - y^2)} } \, dy[/tex] would be the integral that gives the volume of the solid.

I'm Teresa. My friend John and I need to prove that all circles are similar. It seems obvious, right?! Of course they're similar, they’re all circles!
[Many circles of different sizes and colors pop up onto the screen.]
Um, this is making me a little dizzy.
[The circles disappear.]
But we do need to prove that all circles are mathematically similar.
Here’s the way John looks at it: Remember what we learned about similar triangles?
[Two triangles appear on the screen. One is small and the other is large.]
We can take one triangle, and move it on top of another triangle.
[The small triangle is placed on top of the large triangle.]
Then, we dilate it to show that they are similar. Like that.
[The small triangle is dilated to the size of the large triangle.]
John says we can do the same thing with circles.
[Two circles appear on the screen. One is small and the other is large.]
Take any two circles, and move them so that they have the same center.
[The small circle is moved on top of the large circle.]
Then, you can dilate or contract the circles until they are the same size.
[The small circle is dilated to the size of the large circle.]
Taa-daa! The circles are similar. I have another way to prove it.
[Two triangles appear on the screen. The small triangle has sides of length 2, 2, and 3 and the large triangle has sides of length 6, 6, and 9.]
We also know that triangles are similar if all of their corresponding sides have the same ratio.
[The corresponding sides of the triangle are highlighted. On-screen text: 2 over 6 equals 2 over 6 which equals 3 over 9 which equals 1 over 3 Similar!]
Well, the same idea should also work with circles.
[Two circles appear on the screen. One circle is small and the other circle is large.]
If the corresponding parts of two circles have the same ratio, then the circles must be similar. And lucky for us, everything about a circle can be described with its radius!
[Beneath the small circle is written "equals r sub 1." Inside the large circle is written "equals r sub 2." On-screen text: Diameter equals 2r, Circumference equals 2pi r, and Area equals pi r squared.]
So, if the radii of these circles have a constant ratio, then the circles are similar.
[On-screen text: If r sub 1 over r sub 2 equals k, a constant, then the circles are similar.]
What's more, I think I can prove all this by using inscribed triangles. But I need your help.
[A triangle is inscribed in each of the circles using the diameter of the circles as their bases.]
Can we actually use inscribed right triangles to show that all circles are similar?
Step-by-step explanation:
Classmate Conjecture
John | All circles are similar if they have the same center and can be dilated or contracted to the same size.
Teresa | All circles are similar if their corresponding radii have a constant ratio.
Evaluate the Conjectures:
2. Yes, it makes intuitive sense that all circles are similar because they all have the same shape and form.
Construct the Circles:
3. [Diagram not provided]
[Diagram not provided]
The hypotenuse of △ABC is the diameter of the smaller circle.
[Diagram not provided]
The hypotenuse of △XYZ is the diameter of the larger circle.
The two triangles, △ABC and △XYZ, are similar because they are both isosceles right triangles with the same angle measures.
The ratio of the lengths of their sides are equal, therefore the ratio of their radii is a constant.
Making a Decision:
10. Both John and Teresa were right as all circles are similar if they have the same center and can be dilated or contracted to the same size (John's method) and also if their corresponding radii have a constant ratio (Teresa's method).
Further Exploration:
11. The circumference of the circle that circumscribes a triangle with side lengths 3, 4, and 5 can be found using the Pythagorean theorem to find the diameter of the circle, which is equal to the sum of the lengths of the three sides. The diameter is equal to 5, so the circumference is equal to 2 * pi * (5 / 2) = 5 * pi

Jessie is baking a cake and uses 1/2 of the 4
pound bag of flour. How many pounds of
flour did Jessie use to bake her cake?
Answer: 2 pounds of flour
Step-by-step explanation:
1/2 of four is two,
4 * 1/2 = 2
Answer:
Jessie used 1/2 of the 4-pound bag of flour, so she used 1/2 * 4 pounds = 2 pounds of flour to bake her cake.
Suppose that Y1 and Y2 are independent, standard normal random variables. Find the density function of U = Y1^2 +Y2^2.
The cumulative distribution function (CDF) of U is also well known and is given by:
F(u) = 1 - [tex]e^{(-u/2)}[/tex] × γ(1/2, u/2)
where γ is the lower incomplete gamma function.
What is the chi-squared distribution?
The chi-squared distribution is a continuous probability distribution that is widely used in statistics and other fields.
The random variable U = Y1^2 + Y2^2 has a well-known distribution called the chi-squared distribution with two degrees of freedom. The density function of U is given by:
[tex]f(u) = (1 / (2 \times \pi)) \times e^{(-u/2)} \times (u/2)^{(1/2 - 1)}[/tex]
where e is the base of the natural logarithm and π is the mathematical constant pi. This distribution has a positive support on the interval [0, +∞).
The cumulative distribution function (CDF) of U is also well known and is given by:
F(u) = 1 - [tex]e^{(-u/2)}[/tex] × γ(1/2, u/2)
where γ is the lower incomplete gamma function.
