B. 40º
C. 140º
D. 155º

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.

Answer: 1/10

Step-by-step explanation: because there are 10 numbers (1,2,3,4,5,6,7,8,9, and 0)

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

So,

Total Canadian Dollars = $500.00 US times $1.05 Canadian

Therefore, Terence would get $525.00 Canadian for his $500.00 US.

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.

Step-by-step explanation:

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]

Entonces:

[tex]Tasa\hspace{3}de\hspace{3}variacion=-7-14=-21\hspace{3}Negativa[/tex]

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.

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.

Step-by-step explanation:

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.

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: 60°

Step-by-step explanation:

π/3

Since π is denoted as 180°, the question can be rewritten as:

π/3 .

To convert π/3 radians to the nearest degree will be:

π/3 = 180/3

= 60°

This shows that the value of π/3 rads is equal to 60°

Data;

The formula of conversion from radians to degrees is given as

[tex]\pi rads = 180^0[/tex]

Let's convert our given radians to degrees.

[tex]\pi rads = 180^0\\\frac{\pi}{3} = ?\\[/tex]

This becomes

[tex]\frac{\pi }{3} * 180 = \pi \\\\\frac{\pi }{3} rads = \frac{180}{3} \\\frac{\pi }{3} rads = 60^0[/tex]

What we did was equate π rads to 180°, cross multiply the sides with π/3 and solve.

This shows that π/3 rads is equal to 60°

To change a division of fractions to a multiplication problem, you multiply by the reciprocal of one of the numbers (use the KFC rule of Keep, Flip, Change). Keep 7/9, flip the sign (division to multiplication), and change 3/8.

11x+5 = 1/2(10x-6 + 100)

Multiply each side by 2

2(11x+5 )= (10x-6 + 100)

Distribute

22x +10 = 10x+94

Subtract 10x from each side

22x-10x +10 = 10x-10x+94

12x +10 = 94

Subtract 10 from each side

12x = 94-10

12x = 84

Divide each side by 12

12x/12 = 84/12

Option a is correct

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]
