Explain how you would create and use a spinner to simulate the probability of an event with the following probabilities:
Percent chance: 20% green, ¼ blue, ⅖ yellow, and 15% orange
To simulate the probability in a spinner divide the spinner into colors depending on the probability each color represents.
What does the word "probability" mean?This word refers to the likelihood for an event to occur. Moreover, it is often expressed either as a fraction, a percentage, or a number.
How to create a spinner to simulate probability?In this case, each of the colors represents a probability:
Green 20%Blue 1/4 or 25%Yellow 2/5 oe 40%Orange 15%Due to this, the best is to divide the spinner by colors and considering the percentanges of each color. For example 40% of the spinner should be red, while 15% should be orange.

Answer:
B) 77.5 square feet
Step-by-step explanation:
cut shape into rectangle and triangle
area of rectangle = x*y
area of rectangle = 5*13
area of rectangle = 65
area of triangle = (z-x)*(y-w)/2
area of triangle = 5*3/2
area of triangle = 7.5
Total area = 65 + 7.5
Total area = 77.5, B)
Answer:
77.5
Step-by-step explanation:
Cut the figure into a triangle and a rectangle
XxY=65
Z-x=5
Y-W=5
5x5=25

Answer:24
Step-by-step explanation:
a^2+b^2=c^2
c^2 has to be 26 because it is the hypotinuce. 10 could take the place of a^2 or b^2, it dose not matter.
a^2+10^2=26^2
a^2+100=676
subtract 100 from both sides
a^2=576
sqrt576
a=24
x=a
x=24

Last year, Dan opened an investment account with $6600. At the end of the year, the amount in the account had increased by 26.5%. How much is this increase
in dollars? How much money was in his account at the end of last year?
Answer:
1,749
8,349
Step-by-step explanation:
We can multiply 6,600 by 1.265 to get 8,349. To get the percentage all we have to do is multiply 6,600 by .265 and get 1,749.

47. Racing cars driven by Chris and Kelly are side by side at the start of a race. The table shows the velocities of each car (in miles per hour) during the first ten seconds of the race. Use the Midpoint Rule to estimate how much farther Kelly travels than Chris does during the first ten seconds.
Use the Midpoint Rule Kelly travels 12m/s more than Chris does during the first ten seconds.
What is the midpoint rule?The midpoint rule is the rule that follows the median of a set of values which is the middle value when the values are written in numerical order.
From the table above, the midpoint for the velocity of Chris car = 81, while the midpoint for the velocity of Kelly's car = 93
Therefore, the Kelly's car travelled 93-81 = 12 m/s farther than Chris does during the first ten seconds.

Find the value of x.
Explain your answer.
Answer:
Step-by-step explanation:
The hypotenuse is 16 and the adjacent angle is x.
So using SohCahToh
O is opposite, H is the hypotenuse, and A is adjacent.
Soh: sin(theta)= O/H
Cah: cos(theta)= A/H
Toh: tan(theta)= O/A
Any side length that is next to degree 60° is adjacent so x is adjecent.
Using Cah.
cos(theta)= A/H
cos(60°)= x/16
x=16*cos(60°)
x=16*1/2
x=8
solve only number 6
To find the tangent line of the graph:
⇒ must find:
point at which the tangent line touches the graphslope of the tangent lineLet's find the point at which the tangent line touches the graph:
At x = -1,
[tex]y = ((-1)^3+2)^5=(-1+2)^5=1^5=1[/tex]
Point: (-1,1)
Let's find the slope of the tangent line
⇒ get the derivation of function than plug (-1) in the x-position to get
the exact slope
[tex]\frac{d}{dx}(x^3+2)^5=5(x^3+2)^4*\frac{d}{dx}(x^3+2)=5(x^3+2)^4*3x^2\\ \\ 5((-1)^3)+2)^4*3(-1)^2=5(-1+2)^4*3*1=5*(1)^4*3=5*1*3=15[/tex]
Slope of tangent line: 15
Now put all the calculated value into the point-slope form:
[tex](y-y_{0})=m(x-x_{0} )[/tex]
[tex](x_{0} ,y_{0} )[/tex] --> point on the tangent linem --> tangent slope's valueSo:
[tex](y-1)=15(x+1)\\y - 1= 15x + 15\\y = 15x + 15 + 1\\y = 15x + 16[/tex]
Thus the tangent line's equation is y = 15x + 16
Answer: y = 15x + 16

Solve using the elimination method -4x-2y=-18
Step-by-step explanation:
-4x – 2y= -18
Add 2y to both sides
-4x- 2y+ 2y = -18 + 2y
Simplify
-4x = -18 + 2y
Divide both sides by -4
-4x/-4= -18/-4+ 2y/-4
simplify
x= - -9+y/2

Translate the following phrase into an algebraic expression. Do not simplify. Use the variable names "x" or "y" to describe the unknowns.
8 divided by the sum of 2 and a number
Answer:
8/x+2 or [tex]\frac{8}{2+x}[/tex]
Step-by-step explanation:
To answer, carefully read the question and pick up on key words like "sum." To begin, we know that "sum" means addition, therefore the sum of 2 and a number (which will be replaced by the variable x) is equivilent to 2 + x. Furthermore, we know that 8 is being divided by the sum. So, the final expression should be [tex]\frac{8}{2+x}[/tex] . Good luck!

Answer:
7 1/5
Step-by-step explanation:
The bucket was halfway full. It still had 3 3/5 gallons in it. So all you'd have to do is multiply 3 3/5 by 2. Here is the actual work for proof:
