Answer:

closer to 8000 than it is to 7000

Answer:

Hope this helps :)

7,614 is closer to 8,000 than it is to 7,000

This is because if the number has the hundreds place with 500 or more than it would be round up. If it's less than 500 than round down.

Also 7,614 rounded to the nearest thousand is 8,000 because the 6 in the hundreds place is more than 5 so we round up in the thousands place. The final answer would be 8,000.

Q2

Using conditional probability, it is found that the correct option regarding whether the events are independent is given by:

A. No, they are not independent because P(student) = 0.80 and P(student|Viking) =0.94.

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which:

An event B is classified as independent if:

P(B|A) = P(B).

In this problem, 100 out of the 125 people sampled are students, hence the probability is given by:

P(student) = 100/125 = 0.8.

Out of the people that prefer to be a Viking, 80 out of 85 people are students, hence:

P(student|Viking) = 80/85= 0.94.

The probabilities are different, hence the events are not independent, and option A is correct.

x = - 71

Step-by-step explanation:

-11x -44 + 10 x =27

-x = 71

x = - 71

Answer:

-71

Step-by-step explanation:

You can first distribute the numbers in the parenthesis.

-11x-44 (-11*x-11*4)

-11x-44+10x=27

You can now combine like terms.

-11x+10x=-1x

-1x-44=27

This is now a two-step equation problem.

-1x-44=27

    +44=+44

     -1x=71

       [tex]\frac{-1x}{-1}[/tex] =[tex]\frac{71}{-1}[/tex]

x=-71

Answer:

$460

Step-by-step explanation:

If the 128.80 is the price of the desk after a 72% discount, it means that 128.80 is 100-72=28% of the original price.

From here, we can divide 128.80 by 28 to find what 1% of the price is then multiply the value by 100 to find 100%, or the original price.

128.80/28 = 4.6

4.6 x 100 = 460

Original price = $460

Answer:

3x - 9

Step-by-step explanation:

We already have the expression 4x + 2x − 3x − 9. Now, we just have to add like-terms. This will give us 3x - 9.

Step-by-step explanation:

2x(2)+2x(1)-3(x)-3(3)

4x+2x- 3x-9

=======================================================

Explanation:

I'm not sure how your calculator works, but I'm assuming you can copy/paste the given numbers into the calculator somehow to have it determine the regression equation.

The tool I used is GeoGebra and the regression equation it produced was

y = 1.2x - 21.3

Each decimal value is approximate and rounded to the nearest tenth.

---------------------------

Once we determine the regression line, plug the homework grade x = 45 to find the associated test grade (y). This is a predicted test grade.

y = 1.2x - 21.3

y = 1.2*45 - 21.3

y = 32.7

y = 33

If a student got a 45 on a homework, then we predict their test grade should be around 33.

The polar form of the equation represents all the points with a distance of 8 from the origin, which is a circumference with a radius of 8, centered on the origin.

The polar form is represented with the aid of polar coordinates of real and imaginary numbers in the coordinate system.

The horizontal and the vertical axis of the polar form denote the real axis and the imaginary axis, respectively.

The given equation to polar form is;

[tex]\rm x^2+y^2=64[/tex]

Using the formulae that link Cartesian to Polar coordinates.

x = rcosθ and y = rsinθ

Substitute these values into the equation.

[tex]\rm x^2+y^2=64\\\\(rcos\theta)^2+(rsin\theta)^2=64\\\\r^2cos^2\theta +r^2sin^2\theta =64\\\\r^2(cos\theta^2+sin\theta^2)=64\\\\Where ; \ sin^2\theta + cos^2\theta=1\\\\r^2(1)=64\\\\ r^2=8^2\\\\r=8[/tex]

Hence, the polar form of the equation represents all the points with a distance of 8 from the origin, which is a circumference with a radius of 8, centered on the origin.

The speed to his sister house is 50mph.

The speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here, let the speed of his sisters house be x mph.

then, 3x = 2.5(x+10)

         3x = 2.5x + 25

        3x - 2.5x = 25

The number of the pages in the book if the first page will be numbered as 1 will be 1099 pages. And if the number of the pages is n then the function is shown below.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

In numbering pages of a book, a printer used 3289 digits.

Then the number of the pages in the book if the first page will be numbered as 1.

One digit number = 1 - 9 = 9 digits

Two digit number = 10 - 99 = 2 x 90 = 180 digits

Three digit number = 100 - 999 = 3 x 900 = 2700 digits

Then the total number of the digit is used will be

→ 9 + 180 + 2700

→ 2889

The number of the remaining digits will be

→ 3289 - 2889

→ 400

Then the four-digit number will be

→ 400/4

→ 100

Then the total number of the pages will be

Total pages = 9 + 90 + 900 + 100

Total pages = 1099

If n pages are there, then the number of the digits are required will be

[tex]\left\{\begin{matrix}n, & 1\leq n\leq 9 \\9+(n-9)2, & 10\leq n\leq 99 \\189+(n-9)3, & 100\leq n\leq 999 \\. & . \\. & . \\\end{matrix}\right.[/tex]

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are given for every incorrect answer, and 0 marks are given for questions that are not attempted. Punit scored (– 2) marks.

If he answered 3 questions correctly, then the number of the question are got wrong and the number of the question that he did not attempt.

Let x be the correct question and y be the incorrect question, z be the number of questions that he did not attempt, and A be the number of the total score. Then we have

4x – 2z = A

x + y + z = 15

If A = -2 and x = 3, then we have
