Answer: The answer is 0.04
Step-by-step explanation:
To determine the height of a triangle-shaped density curve spanning from 0 to 50 years, we use the fact that the area under the density curve must equal 1. The equation (50 * height) / 2 = 1 allows us to solve for the height, which is 0.04 on the probability density scale.
Explanation:To determine the height of the triangle representing a density curve for possible ages, we need some information about the properties of that triangle and density curves in general. A density curve shows how the proportion of a particular measurement (in this case, ages) is spread out over a range. The area under a density curve must equal 1 (or 100%) since it represents the total probability distribution.
In this scenario, we have a triangle as a density curve stretching from 0 to 50 years, which suggests that 0 and 50 are the bounds of our variable (age). The base of the triangle spans these 50 years. If we assume a right-angled triangle for simplicity's sake (which isn't specified in the question but is a common assumption), then the area of the triangle, which represents the probability, would be (base * height) / 2.
To ensure that the total area under the curve equals 1, we set up the following equation: (50 * height) / 2 = 1. Solving this equation for height gives us height = 2 / 50, which simplifies to height = 0.04. Therefore, the height of the density triangle is 0.04 on whatever scale is being used for probability density (e.g., per year).
If f(x) = x^2 is vertically stretched by a factor of 6 to g(x) and reflected over the x-axis, what is the equation for g(x)?
A. g(x) = (-6x)^2
B. g(x) = -6x^2
C. g(x) = x^2-6
D. g(x) = -x^2+6
Answer:
Option B
[tex]g(x) = -6x^2[/tex]
Step-by-step explanation:
If the graph of the function [tex]g(x)=cf(x)[/tex] represents the transformations made to the graph of [tex]y= f(x)[/tex] then, by definition:
If [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor c.
If [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c
If [tex]c <0[/tex] then the graph is reflected on the x axis.
In this problem we have the function [tex]f(x)=x^2[/tex]
We now that this function is vertically stretched by a factor of 6 to g(x) and reflected over the x-axis
Then [tex]|c| =6 >0[/tex] and [tex]c=-6<0[/tex]
Therefore the graph of [tex]g(x)[/tex] is [tex]g(x) = -6f(x)[/tex]
[tex]g(x) = -6x^2[/tex]

At a deli, Aaron bought 2/3 of a pound of sliced turkey for $4.36. What is the unit price of sliced turkey at the deli? Round answers to the nearest cent.
$4.36 per pound
$6.54 per pound
$2.91 per pound
$5.03 per pound
$8.72 per pound
Answer:
$6.54 per pound
Step-by-step explanation:
we know that
To find the unit price divide the total cost by the total pounds
so
[tex]\frac{4.36}{(2/3)}=\frac{4.36*3}{2}=\$6.54\ per\ pound[/tex]

Which of the following statements are correct? Select all that apply.
-- Only two of three angle bisectors of the internal angles of a triangle are concurrent.
-- The circumcenter of a triangle is the point where the perpendicular bisectors of the sides meet.
-- Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- A circumscribed circle is the circle that passes through all three vertices of a triangle and it is the smallest triangle contained within any triangle.
-- The incenter of a triangle is the point where the angle bisectors meet.
Answer:
Step-by-step explanation:
Given are some properties of triangles and we have to check whether they are correct
i) Only two of three angle bisectors of the internal angles of a triangle are concurrent.
This is incorrect since all three angle bisectors concur at incentre
ii) The circumcenter of a triangle is the point where the perpendicular bisectors of the sides meet.
-- correct because the meeting point is equidistant from all three vertices
iii) Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- correct because any three points determine a circle
iv) Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- Correct
v) The incenter of a triangle is the point where the angle bisectors meet.
-- Correct and the centre is equidistant from the sides of the triangle
Statements 2, 3, and 5 are correct.
Analyze each statement to determine which are correct:
Only two of three angle bisectors of the internal angles of a triangle are concurrent. This statement is incorrect. All three angle bisectors of the internal angles of a triangle are concurrent and meet at a single point called the incenter.The circumcenter of a triangle is the point where the perpendicular bisectors of the sides meet. This statement is correct. The perpendicular bisectors of the sides of a triangle meet at a point called the circumcenter, which is the center of the circle that passes through all three vertices of the triangle (circumscribed circle).Given any three non-collinear points, there exists exactly one circle that passes through the points. This statement is correct. For any three non-collinear points, there is exactly one unique circle that can pass through all three points. This is the circumscribed circle of the triangle formed by the points.A circumscribed circle is the circle that passes through all three vertices of a triangle and it is the smallest triangle contained within any triangle. This statement is incorrect. While a circumscribed circle does pass through all three vertices of a triangle, it does not describe any triangle, let alone the smallest one contained within another triangle.The incenter of a triangle is the point where the angle bisectors meet. This statement is correct. The incenter, where the angle bisectors meet, is the center of the inscribed circle that fits inside the triangle.The blue triangle has been reflected to the red triangle.

The pizza parlor is running a special on 3-toppings pizzas. The topping choices include pepperoni, sausage, bacon mushrooms, onions, green peppers, and black olives. The next customer who orders 3-topping pizza tells the chef to randomly choose 3 different toppings for their pizza. What is the probability that customer will get a pizza topped with pepperoni, mushrooms, green peppers? The teacher told us the solution is 1/35 but he wants an explanation of why is that solution correct.
Answer:
Well there are 6 toppings. For one person to select sausage, it is \frac{1}{6} . For two people, multiply them together and the probability is \frac{1}{36}
What is the solution of the equation?
b + 5/6 = 10
Answer:
b = 9 1/6
Step-by-step explanation:
b + 5/6 = 10
Subtract 5/6 from each side
b + 5/6 -5/6= 10-5/6
b = 10 -5/6
Borrow 1 from the 10 in the form of 6/6
b = 9 +6/6 - 5/6
b = 9 +1/6
b = 9 1/6
Graph y=sin^-1 (1/4 x) on the interval -5≤x≤5.
Answer:
D
Step-by-step explanation:
The arcsine ([tex]\sin^{-1}[/tex]) function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when
[tex]-4\le x\le 4,[/tex]
we have that
[tex]-1\le \dfrac{1}{4}x\le 1.[/tex]
This gives us the domain [tex]-4\le x\le 4[/tex] of the function [tex]y=\sin^{-1}\left(\dfrac{1}{4}x\right).[/tex]
The range of the function [tex]y=\sin^{-1}x[/tex] is [tex]-\dfrac{\pi }{2}\le x\le \dfrac{\pi }{2},[/tex] so the range of the function [tex]y=\sin^{-1}\left(\dfrac{1}{4}x\right)[/tex] is the same (options A and C are false).
When x=-4,
[tex]y=\sin^{-1}\left(\dfrac{1}{4}\cdot (-4)\right)=\sin^{-1}(-1)=-\dfrac{\pi}{2}.[/tex]
So, option B is false and option D is true.
Allie and Evelyn share a pizza and split the cost. They each pay $7.74. Which of the following equations can be used to find the cost of the pizza?
2p = 7.74
7.74/2 = p
7.74/p = 2
p/2 = 7.74
p/2=7.74
This was a trick question. P is the variable that represents the total cost of the pizza. To normally find the total cost of pizza using the cost each of the two people spent, you would simply multiply 7.74*2=p. Since that wasn’t in the choices, you can divide by two on each side to get p/2=7.74.

Step-by-step explanation:
Translations are a type of rigid transformation of functions, in which the position of the graph of a function is modified. The general form of the graph of a function moves up, down, left, or right.
Vertical translations:
Let:
[tex]a >0[/tex]
[tex]y=f(x)+a[/tex] shifts the graph [tex]a[/tex] units up
[tex]y=f(x)-a[/tex] shifts the graph [tex]a[/tex] units down
Horizontal translations:
Let:
[tex]b>0[/tex]
[tex]y=f(x+a)[/tex] shifts the graph [tex]b[/tex] units to the left.
[tex]y=f(x-a)[/tex] shifts the graph [tex]b[/tex] units to the right.
Using the previous information we can conclude that the function:
[tex]f(x-3)[/tex]
Is a Horizontal translation in which the graph was shifted [tex]b=3[/tex] units to the right.
[tex]f(x-3)=(x-3)^3[/tex]
I leave you the graphs, so you can corroborate the answer easily.

Answer:
The answer is AB.
Choice D.
Step-by-step explanation:
We are given four blood types and the number of females and males having each of the blood type. We are to determine the blood type that is independent of the gender.
It is evident that the disparity in the number of males and females in the blood types A, B and O is large.
Only in the blood type AB, the difference is very small. The number of males and females having AB blood type is more or less same. So, we can conclude that blood type AB is independent of gender.

Let point Q = (4,y)
√[ (4-0)^2 + (y-0)^2 ] = √[ (6-0)^2 + (0-0)^2 ]
Square both side
(4-0)^2 + (y-0)^2 = (6-0)^2 + (0-0)^2
4^2 + y^2 = 6^2
16 + y^2 = 36
y^2 = 36-16
y^2 = 20
y= √20
y= 2√5
Answer:
2√5
Step-by-step explanation:
On the graphic, you see point Q is roughly between 4 and 4.5 units on the Y-axis.
So, all we have to do is find a value similar to that in the answer choices. So, let's look at the values:
2√5: 2 * 2.23 = 4.46... that's pretty much what we're looking for.
4√2: 4 * 1.41 = 6.4. Way too big.
2√13: 2 * 3.6 = 7.2, way too big.
8√2: We know that will necessary be way bigger than 4.5, so let's not even evaluate it.
Which characteristic is correct for the function f(x)=−2x^3+3x ?
Answer:
Left ends is +ve infinity and Right end is -ve infinity. however both tends to be infinity.
Step-by-step explanation:
Let us under stand the basics of determining the end behavior of a graph , by just analyzing the degrees and coefficient of a polynomial.Please refer to the image we have shared with this for a better understanding also.
The rule is bifurcated in two broad category and and two sub category in them.
Category .
The nature of degree (Even / Odd )
Subcategory .
The coefficient of term containing degree ( Negative/Positive )
Rule 1 :
Degree : Even
If coefficient is
Rule 1(a) : Positive ⇒Both ends are towards +ve infinity
Rule 1(b) : Negative⇒Both ends are towards -ve infinity
Rule 2 :
Degree : Odd
If coefficient is
Rule 2(a) : Positive ⇒ Left ends is -ve infinity and Right end is +ve infinity
Rule 2(b) : Negative ⇒ Left ends is +ve infinity and Right end is -ve infinity
Let us see our function f(x) = [tex]-2x^3 + 3x[/tex] now
Here
Degree is 3 which is Odd
Its coefficient is (-2) which is negative
Hence we go to rule 2(b)
That is the Left ends is +ve infinity and Right end is -ve infinity. however both tends to be infinity.

State the domain and range for the function
Answer:
* Domain: all reals except multiples of 2π
* Range: (-∞ , -2] ∪ [2 , ∞)
Step-by-step explanation:
* Lets revise the period, the domain and the range of csc(x)
- The period of csc(x) is 2π
- To find the period of csc(x) use 2π / coefficient of x
- The domain of csc(x) is all x ≠ nπ
- The range is y ≤ -1 , y ≥ 1
* Lets revise the vertical and the horizontal stretch and compress
- A vertical stretching is the stretching of the graph away from
the x-axis
• if k > 1, the graph of y = k•f(x) is the graph of f(x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each of its y-coordinates by k.
- A horizontal stretching is the stretching of the graph away from
the y-axis
• if 0 < k < 1 (a fraction), the graph is f (x) horizontally stretched by
dividing each of its x-coordinates by k.
- A horizontal compression is the squeezing of the graph toward
the y-axis.
• if k > 1, the graph of y = f (k•x) is the graph of f (x) horizontally
compressed by dividing each of its x-coordinates by k
∵ f(x) = 2csc(x/2)
- The coefficient of x is 1/2
∵ The period of x = 2π
∴ The period of x/2 = 2π/1/2 = 4π
∵ The domain of csc(x) is all x ≠ nπ
∴ The domain of csc(x/2) is all x ≠ n2π
∵ f(x) = 2csc(x/2)
∵ csc(x/2) multiplying by 2
- That means every y-coefficient multiplying by 2
∵ The range of csc(x/2) is y ≤ -1 and y ≥ 1
∴ The rang of f(x) = 2csc(x/2) is y ≤ -1(2) and y ≥ 1(2)
∴ The rang of f(x) = 2csc(x/2) is y ≤ -2 and y ≥ 2
* Domain: all reals except multiples of 2π
* Range: (-∞ , -2] ∪ [2 , ∞)
* Look to the graph attached
- The red is y = csc(x)
- The blue is f(x) = 2csc(x/2)
Nemo's aquarium is filled with 240024002400 cubic centimeters of water. The base of the aquarium is 20\text{ cm}20 cm20, space, c, m long and 12\text{ cm}12 cm12, space, c, m wide. What is the height of the water in Nemo's aquarium?
Answer:
10 cm
Step-by-step explanation:
Answer:
10 cm
Step-by-step explanation:
Since, the volume of a cuboid is,
V = l × w × h,
Where,
l = length,
w = width,
h = height,
∵ The shape of the aquarium must be cuboid,
We have, l = 20 cm, w = 12 cm, V = 2400 cm³,
By substituting the values,
2400 = 20 × 12 × h
2400 = 240h
[tex]\implies h = \frac{2400}{240}=10[/tex]
Hence, the height of the water in Nemo's aquarium would be 10 cm.

How to Identify the number of vertices, edges, and faces?A polyhedron is a 3-dimensional solid made by joining together polygons. Face: The flat surfaces that make up a polyhedron
Edges: It is a line segment formed when two faces meet up.
Vertices: It is the point of intersection of the edges of the polyhedron. Taking an example of Tetrahedron.
It has 4 faces, 4 vertices and 6 edges. Recall Euler's formula which states F + V = E + 2
where F, V, and E represent the number of faces, edges, and vertices of the polyhedron respectively. Verifying the Euler's formula for tetrahedron F = 4V = 4E = 6
so 4 + 4 = 6 + 2
Hence we can verify the Euler's formula.

Help me with this trig question
Answer:
Answer 2
Step-by-step explanation:
We start with (log to the base x of 8) = y and want to find the value of y.
Obviously the base here is x.
Therefore,
(log to the base x of 8) y
x = x
The quantity on the left side of this equation simplifies to 8.
y
Then we have 8 = x
We'll need to solve this equation for y. To do so, take the common log of both sides, obtaining:
log 8
log 8 = y log x, so that y = ----------- This corresponds to given answer 2.
log x
The Venn diagram shows the results of two events resulting from rolling a number cube.
Events C and D are____.
P(C) = 1/3
P(D) = 1/3
P(C ∩ D) = 0
P(C | D) ≠ 0
This is geometry, dealing with conditional probability.
Answer:
Events C and D are mutually exclusive.
P(C ∩ D) = 0
Step-by-step explanation:
We notice that event C is even numbers and Event D is odd number. We cannot roll a die and have both events occur at the same time. That means they are mutually exclusive. Either one event occurs or the other occurs.
P(C ∩ D) = 0 This means the events do not intersect (overlap). Or are mutually exclusive.

There is a clown's face on the top of a spinner. The tip of his hat rotates to (−2, 5) during one spin. What is the cosine value of this function?
−2
5
5 square root of 29 over 29
negative 2 square root of 29 over 29
Answer:
The last choice is your answer
Step-by-step explanation:
Plot your point in an x/y coordinate plane. We are in QII where x is negative and y is positive. From that point, if you drop an altitude to the negative x axis, you have a right triangle with a base measure of -2, a height of 5 and a hypotenuse that is unknown as of right now. We will find it using Pythagorean's Theorem. [tex]5^2+(-2)^2=c^2[/tex]
The length of the hypotenuse is √29. That means that the cosine of that angle is the side adjacent over the hypotenuse. Rationalizing the denominator gives us [tex]-\frac{2\sqrt{29} }{29}[/tex]

The water bill increases by about $87 for every additional resident in the home
Answer:
The water bill increases by about $19 for every additional resident in the home
Step-by-step explanation:
This is because times x shows that it is to each and every person and it is increasing.
Answer:
The answer is C. The water bill increases by about $19 for every additional resident in the home.
Step-by-step explanation:
The equation above consists of y as the dependent variable, x as the independent variable, 19.485 as the slope, and 86.912 as the constant. The constant represent the fixed water bill. The x variable represents the additional water usage.
