Barry has a spinner that has 2 equal sections of red and green and 2 marbles, one white and one black. Which of the following represents the sample space for spinning the spinner and picking a black or white marble?
A
B
C
D
Your answer would be the last option, D.
This is because spinning the spinner does not affect which marble you pick, as these are mutually exclusive events. This means that if the spinner lands on red, you could choose a black or white marble, and if the spinner lands on green you could also choose a black or white marble.
The only sample space that represents this is D because it's the only one that includes both black and white options after spinning red and green.
I hope this helps!

The population of Casperville is 1450. A sample of 100 people in the town was asked if they owned a landline, and 6 responded yes. What is the best estimate of the percent of the people in Casperville who will have landlines?
Answer:
Step-by-step explanation:
Hello!
The variable of interest is:
X: Number of people in Casperville that own a landline out of 100 people.
There is a fixed number of surveys made (trials) n=100, for each trial there are two possible answers, "success": the person owns a landline, and "failure": the person doesn't own a landline. Assuming each person is independent of the others and that the probability of success is the same for all trials, we can say that this variable has a binomial distribution: X~Bi(n;p)
To estimate the proportion/ percentage of people in Casperville that owns a landline you have to calculate the sample proportion:
^p=[tex]\frac{number of "successes"}{n} = \frac{6}{100} = 0.06[/tex]
6% of the people surveyed owns a landline.

π/6(that's supposed to be a fraction)
A real
B irrational
C whole
D integer
The value π/6 is a real number and not an integer, whole or irrational number. This is because it's expressed as a fraction, disqualifying it from being either an integer or whole number, and because it's found on the number line, making it a real number.
Explanation:The given value π/6 represents a fractional value in the context of mathematics. This number is not an integer nor a whole number, because those categories only include non-fractional numbers. The value is real, which is a category that includes all numbers that can be positioned on the number line, inclusive of both rational and irrational numbers. The given number, π/6, is not an irrational number, because irrational numbers are numbers which cannot be expressed as a fraction, and our given number, π/6, is obviously expressed as a fraction.

Answer:
[tex]A) \hspace{3}Rate\hspace{3}of\hspace{3}change=-5\hspace{3}Negative\\\\B)\hspace{3}Rate\hspace{3}of\hspace{3}change=-21\hspace{3}Negative[/tex]
Step-by-step explanation:
Given a function [tex]f(x)[/tex], we called the rate of change to the number that represents the increase or decrease that the function experiences when increasing the independent variable from one value "[tex]x_1[/tex]" to another "[tex]x_2[/tex]".
The rate of change of [tex]f(x)[/tex] between [tex]x_1[/tex] and [tex]x_2[/tex] can be calculated as follows:
[tex]Rate\hspace{3}of\hspace{3}change=f(x_2)-f(x_1)[/tex]
For:
[tex]f(x)=x^2-2x+4[/tex]
Let's find [tex]f(x_1)[/tex] and [tex]f(x_2)[/tex], where:
[tex][x_1,x_2]=[-4,3][/tex]
[tex]f(x_1)=f(-4)=(-4)^2-2(4)+4=16-8+4=12\\f(x_2)=f(3)=(3)^2-2(3)+4=9-6+4=7[/tex]
So:
[tex]Rate\hspace{3}of\hspace{3}change =7-12=-5\hspace{3}Negative[/tex]
And for:
[tex]f(x)-3x+2[/tex]
Let's find [tex]f(x_1)[/tex] and [tex]f(x_2)[/tex], where:
[tex][x_1,x_2]=[-4,3][/tex]
[tex]f(x_1)=f(-4)=-3(-4)+2=12+2=14\\f(x_2)=f(3)=-3(3)+2=-9+2=-7[/tex]
So:
[tex]Rate\hspace{3}of\hspace{3}change =-7-14=-21\hspace{3}Negative[/tex]
Translation:
Dada una función [tex]f(x)[/tex], llamábamos tasa de variación al número que representa el aumento o disminución que experimenta la función al aumentar la variable independiente de un valor "[tex]x_1[/tex]" a otro "[tex]x_2[/tex]".
La tasa de variación de [tex]f(x)[/tex] entre [tex]x_1[/tex] y [tex]x_2[/tex], puede ser calculada de la siguiente forma:
[tex]Tasa\hspace{3}de\hspace{3}variacion=f(x_2)-f(x_1)[/tex]
Para:
[tex]f(x)=x^2-2x+4[/tex]
Encontremos [tex]f(x_1)[/tex] y [tex]f(x_2)[/tex], donde:
[tex][x_1,x_2]=[-4,3][/tex]
[tex]f(x_1)=f(-4)=-3(-4)+2=12+2=14\\f(x_2)=f(3)=-3(3)+2=-9+2=-7[/tex]
Entonces:
[tex]Tasa\hspace{3}de\hspace{3}variacion =7-12=-5\hspace{3}Negativa[/tex]
Y para:

[tex]f(x_1)=f(-4)=-3(-4)+2=12+2=14\\f(x_2)=f(3)=-3(3)+2=-9+2=-7[/tex]

The inequality equation is n ≤ 98
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The total number of people the room can hold = 120 people
The number of coaches and players = 22
Let the number of people to be invited be n
So , n + 22 should not be more than 120
On simplifying the equation , we get
n + 22 ≤ 120
Subtracting 22 on both sides of the equation , we get
n ≤ 98
Hence , the inequality is n ≤ 98

Anya’s starting salary was $42,000, and she gets a $1,500 raise each year. Jake’s starting salary was $35,000, and he gets a 3% raise each year.
Answer:
[tex]J(x)=1050x+35000[/tex]
Step-by-step explanation:
The complete question is
Anya and Jake started new jobs at the same time. Anya’s starting salary was $42,000, and she gets a $1,500 raise each year. Jake’s starting salary was $35,000, and he gets a 3% raise each year. What function gives Jake’s salary after x years?
The starting salary refers to the initial condition, the salary Jake began from. That means, it's the constant term in the function.
On the other hand, the constant ratio of change of the function is the yearly raise, which is 3% of $35,000. Let's find how much money it is.
[tex]0.03(35000)=1050[/tex]
This means, they raise Jake's salary $1,050 each year, that's the constant ratio of change.
Therefore, the function which represents Jake's salary is
[tex]J(x)=1050x+35000[/tex]
Where [tex]x[/tex] represents years.

7n-1 >-169
Is it greater than -24 or less than -24
Answer:
It is greater than -24
Step-by-step explanation:
-170 divided by 7 is -24.2857...(repeating)
-170 is from doing -169 - 1
The answer to the question is that 7n - 1 is greater than -24.
To determine the relationship between 7n - 1 and -24, we need to solve the inequality 7n - 1 > -169 and then compare the solution to -24.
First, let's solve the inequality 7n - 1 > -169:
7n - 1 + 1 > -169 + 1
7n > -168
n > -168 / 7
Now, we have the solution to the inequality, which tells us that n must be greater than -24 to satisfy the inequality 7n - 1 > -169.
Since n > -24, it follows that 7n - 1 will also be greater than 7(-24) - 1. Let's calculate 7(-24) - 1:
7(-24) - 1 = -168 - 1 = -169
But we know from the inequality that 7n - 1 is strictly greater than -169. Therefore, 7n - 1 must be greater than -24 as well, because -169 is less than -24.
Hence, 7n - 1 is greater than -24.

Step-by-step explanation:
As 2 phones are defective from a group of 98 that were checked, you can determine a percentage:
2/98= 2%
This indicates that 2% of the phones are likely to be defective and because of that you can find 2% of 850:
850*2%= 17
According to this, 17 phones are likely to be defective.

The length of a rectangle is 5 centimeters less than its width. What’s re the dimensions of the rectangle if it’s area is 300 square centimeters?
I need the length of one of the side and the width
Answer: The length of rectangle is 15 cm and width is 20 cm
Step-by-step explanation:
As according to question
Let the width of rectangle = x cm
Length of rectangle =(x- 5) cm
Area of rectangle is 300 cm²
As we know Area of rectangle is given by
[tex]Area = length \times breadth \\\\\Rightarrow 300 = (x-5)x\\\\\Rightarrow 300 = x^2-5x\\\\\Rightarrow x^2-5x-300 = 0 \\\\\Rightarrow x^2-20x+15x-300 = 0 \\\\\Rightarrow x(x-20) +15(x-20) =0\\\\\Rightarrow (x-20)(x+15)=0[/tex]
Therefore either (x-20)= 0 or (x+15)=0
i.e. either x= 20 or x = -15
Now width can not be negative
Therefore it cant be -15
Hence the width is 20 cm
Length = x- 5 = 20-5 = 15 cm
Hence the length of rectangle is 15 cm and width is 20 cm
Final answer:
To find the dimensions of a rectangle when given the area, set up an equation using the information and solve for the unknowns.
Explanation:
To find the dimensions of the rectangle, we can set up an equation using the given information. Let's use 'L' to represent the length and 'W' to represent the width. The problem states that the length is 5 centimeters less than the width, so we can write the equation as: L = W - 5.
We also know that the area of a rectangle is found by multiplying the length and width together. In this case, the area is given as 300 square centimeters. So, we can write another equation: L * W = 300.
Now, we can substitute L = W - 5 into the second equation to solve for the width. (W - 5) * W = 300. Simplifying this equation will give us a quadratic equation, which we can solve to find the width. Once we know the width, we can subtract 5 to find the length.
