Calculate the probability of the event.
Answer:
well, the other colors on the wheel are less because people prefered green
Step-by-step explanation:
Step-by-step explanation:
So its hard to calculate actual probability without any numbers. But seeing that there are a total of 6 colors on the wheel, and that green is the largest (by a lot since its almost half the wheel) the probability of landing green is very high.
And that's all you can say really...black will be lowest, and yellow seems to be the next highest. In comparison to green though, probability of the other colors will be low.

How many yards are in 4 miles?
Answer: 4 miles are equal to 7040
Step-by-step explanation:
As we know that the ratio can be simplified and the answer can be obtained,
according to the question 5 miles are equal to 8800.
so, here we arrange the ratio in its format as follows
Step 1:
Miles: Yards
5: 8800
Step 2: here we bring the ratio to its simplest form by dividing by 5 on both sides, that is:
5/5=1
8800/5= 1760
Now we get:
Miles: Yards
1: 1760
Step 3: now as we need to find the answer for 4 miles we need to multiply with 4 on both sides, that is:
Miles: Yards
4: 7040
from here we get the answer as 4 milesequalso 7040 yards.

I need some help for this and the graph won’t let you use decimals as the answer. Tip: 1/3 = 0.3
.
Answer:
\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)
See attachment for the graph of the equation.
Step-by-step explanation:
Given equation:
\(y=\dfrac{1}{3}x\)
To complete the table, find the corresponding values of y by substituting each given value of x into the equation.
\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)
\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)
\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)
Therefore the completed table is:
\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)
To graph the equation, plot the ordered pairs on the given coordinate plane:
(6, 2)(12, 4)(18, 6)Draw a straight line through the points. (See attachment).
What value of x satisfies the equation: 6(x-3)+10=2(3x-4)
A) x=22
B) x=-22
C) x=20
D) x=6
Answer:
A)x=22
Step-by-step explanation:
when you substitute in 22 both sides of the equation equal 124
Answer:
Everything; A, B, C, and D.
Step-by-step explanation:
We have the equation:
\(6(x-3)+10=2(3x-4)\)
Let's solve for x. On the left, distribute:
\((6x-18)+10=2(3x-4)\)
Distribute on the right:
\(6x-18+10=6x-8\)
Combine like terms on the left:
\(6x-8=6x-8\)
We can see that both the left- and right-hand side are equivalent.
Therefore, any and all values of x will satisfy our equation.
So, our answer is A, B, C, and D.

A click beetle abruptly releases elastic energy stored in its body to launch itself into the air. The function h(t)=−16t^2+8t represents the height h (in feet) of the click beetle t seconds after launching. The height of a second click beetle t seconds after launching is shown in the graph. Which click beetle went higher?
Answer:
The first click beetle went higher.
Step-by-step explanation:
The vertex is the minimum point of a parabola that opens upwards, or the maximum point of a parabola that opens downwards.
Since the height of each of the beetles at time, t seconds, is modelled as a parabola that opens downwards, the maximum height of each beetle is the y-value of the vertex.
First Click BeetleThe function representing the height, h, of the first beetle is:
\(h(t)=-16t^2+8t\)
We could complete the square to rewrite the function in vertex form, however the quickest way to find the vertex of a quadratic function in the form ax² + bx + c is to use the formula for the x-value of the vertex:
\(\boxed{x_{\sf vertex}=-\dfrac{b}{2a}}\)
Comparing ax² + bx + c with the given function:
a = -16b = 8c = 0Therefore, substituting the values of a and b into the formula, the x-value of the vertex of h(t) is:
\(x_{\sf vertex}=-\dfrac{8}{2(-16)}=0.25\)
To find the y-value of the vertex, and thus the maximum height of the first beetle, simply substitute t = 0.25 into function h(t):
\(\begin{aligned}\implies h(0.25)&=-16(0.25)^2+8(0.25)\\&=-16(0.0625)+2\\&=-1+2\\&=1\end{aligned}\)
Therefore, the maximum height of the first beetle is 1 foot.
Second Click BeetleFrom inspection of the given graph modelling the height of the second beetle, we can see that the maximum y-value is approximately 0.76 feet.
ConclusionAs the height of the second click beetle is less than the maximum height of the first click beetle, the first beetle went higher.
A circle has a diameter of 8 inches. What is the area of this circle? Use 3.14 for pi.
(100 POINTS I NEED THE ANSWER SO I PASS THIS YEAR)
Given that a circle has a diameter of 8 inches and we are required to find its area using 3.14 as pi.
We know that the formula for calculating the area of a circle is A = πr², where A is the area, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.
Since we are given the diameter of the circle, we can calculate its radius using the formula: radius (r) = diameter/2
Therefore, the radius of this circle is: r = 8/2 = 4 inches
Now, we can calculate the area of the circle using the formula: A = πr² Substituting the value of r, we get: A = 3.14 x 4² A = 3.14 x 16 A = 50.24 square inches
Therefore, the area of the circle is 50.24 square inches.
The answer is:
50.24 in²Work/explanation:
The formula for the circle's area :
\(\sf{A=\pi r^2}\)
where :
A = areaπ = 3.14r = radiusWe know the diameter, but the radius is one-half of that, so the radius is :
Radius = Diameter ÷ 2 = 8 ÷ 2 = 4 inchesHere's a diagram for better understanding:
\(\setlength{\unitlength}{1.1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\small 4\ in}\end{picture}\)
Now, plug in the data:
\(\large\begin{gathered}\bf{A=\pi r^2}\\\\\bf{A=3.14\times4^2}\\\\\bf{A=3.14\times16}\\\\\bf{A=50.24\:in^2}\end{gathered}\)
Therefore, the area is 50.24 in².Given what is the domain in set notation? {x|x ∈ R, x ≥ 4} {x|x ∈ R, x ≤ 4} {x|x ∈ R, x ≥ 2} {x|x ∈ R, x ≤ 2}

with a common denominator, it looks like this
21/12 = 1 3/4, 18/12 = 1 1/2 10/12 = 5/6 3/12 = 1/4
The order of the fraction from largest number to smallest number is 1 3/4, 1 1/2, 5/6, and 1/4.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data given in the question,
1 1/2 = 3/2 = 1.5
1/4 = 0.25
1 3/4 = 7/4 = 1.75
5/6 = 0.83
So, the order from largest to smallest number is:
1 3/4, 1 1/2, 5/6, and 1/4.
Now, with a common denominator it will be:
21/12 = 1 3/4, 18/12 = 1 1/2 10/12 = 5/6 3/12 = 1/4

PLSSS HELP State the maximum number of turns the graph of each function could make 1. f(x)=x^5-3x+1 2.f(x)=-x^7-7x^5-4x^3
Answer:
max for 5th-degree: 4 turns. This function: 2 turns.max for 7th-degree: 6 turns. This function: 0 turns.Step-by-step explanation:
In general, the graph of an n-th degree function can make n-1 turns. However, in specific cases, the number of turns is limited by the number of real zero-crossings of the derivative.
__
1. This 5th-degree function can have at most 4 turns. However, the derivative, f'(x) = 5x^4 -3, has only two (2) real zeros. Hence the graph of this function can only have 2 turns.
__
2. This 7th-degree function can have at most 6 turns. However, the derivative, f'(x) = -7x^6 -35x^4-12x^2, has an even-multiplicity root at x=0 only. The derivative never crosses 0. Hence the graph makes no turns.

Jackson works as a veterinary technician and earns $12.20 per hour. Jackson normally works 40 hours a week. And a normal week, what is his total pay before taxes and other deductions
Answer:
p = 12.20h
30.5 hours
Step-by-step explanation:
Jackson works as a veterinary technician and earns per hour = $12.2
He works in a normal week = 40 hours
Let hours = h and weekly pay = p
p = 12.20h
p = $12.20 × 40
= $488.00
Last week Jackson was ill and missed some work.
His total pay before deduction was $372.10
To find the hours he work the equation will be p = 12.20h
372.10 = 12.20h
372.10/12.20 = h
