Step-by-step explanation:
The probability of selecting two solid chocolates in a row is 4/145.
Explanation:To calculate the probability of selecting two solid chocolates in a row, we need to consider the probability of selecting a solid chocolate on the first draw and the probability of selecting a solid chocolate on the second draw, given that a solid chocolate was selected on the first draw.
There are a total of 30 chocolates, with 9 solid chocolates. Therefore, the probability of selecting a solid chocolate on the first draw is 9/30.
After eating the first chocolate, there are now 29 chocolates left in the box, with 8 solid chocolates remaining. So the probability of selecting a second solid chocolate is 8/29.
Since the two events are independent, we can multiply the probabilities of each event to find the probability of both events occurring:
Probability of selecting two solid chocolates = (9/30) * (8/29) = 4/145.

Set equal to zero
0 =x^2-9x+20
Factor
What two numbers multiply to 20 and add to -9

Step-by-step explanation:
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.
Ms. Bell's mathematics class consists of 12 sophomores, 8 juniors, and 13 seniors.
How
many
different ways can Ms. Bell create a 4-member committee of seniors if
each senior has an equal chance of being selected?
To create a 4-member committee of seniors, Ms. Bell can do so in 715 different ways.
Explanation:To find the number of different ways Ms. Bell can create a 4-member committee of seniors, we use the combination formula. The formula for combinations is C(n, r) = n! / (r!(n-r)!) where n is the total number of items and r is the number of items chosen. In this case, n = 13 (number of seniors) and r = 4 (number of members in the committee). Plugging in these values, we calculate C(13, 4) = 13! / (4!(13-4)!) = (13*12*11*10) / (4*3*2*1) = 13 * 11 * 5 = 715.

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)-3x+2[/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]

7. Terence came to Canada shopping on a long weekend.

a) How many Canadian dollars would Terence get for $500.00 US?
Terence would receive $525.00 Canadian after exchanging $500.00 US at an exchange rate of $1.00 US to $1.05 Canadian.
Terence exchanged his US dollars to Canadian dollars with an exchange rate of $1.00 US to $1.05 Canadian. To calculate the amount of Canadian dollars Terence would get for $500.00 US, we use the formula:
Total Canadian Dollars = Amount in US dollars times Exchange rate

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.

Step-by-step explanation:
Given: [tex]3x^4+x^2-1[/tex]
To find: roots of the equation
Solution:
A number x is a root of an equation if it satisfies the equation. It is a real root if it is also a real number.
[tex]3x^4+x^2-1[/tex]
Take [tex]y=x^2[/tex]
[tex]3x^4+x^2-1=3y^2+y-1[/tex]
For an equation of the form [tex]ay^2+by+c=0[/tex], roots are given by [tex]y=\frac{-1\pm \sqrt{1+12}}{6}[/tex]
So,
[tex]x^2=\frac{-1\pm \sqrt{1+12}}{6}=\frac{-1\pm \sqrt{13}}{6}\\x=\pm \sqrt{\left ( \frac{-1\pm \sqrt{13}}{6} \right )}[/tex]
Real zeroes:
[tex]x=\pm \sqrt{\left ( \frac{-1+\sqrt{13}}{6} \right )}\\=\pm \sqrt{\left ( \frac{-1+ 3.61}{6} \right )}\\=\pm \sqrt{\left ( \frac{2.61}{6} \right )} \\=\pm \sqrt{0.44}\\=\pm 0.7[/tex]

A
B
C

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.

An inspector checks 98 cell phones and finds that 2 of them are defective. A company has 850 of these phones. How many of the company's phones are likely to be defective?
Answer:
17
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 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.
