what are the dimensions of a standard piece of paper

Answers

A standard piece of paper typically has dimensions of 8.5 inches by 11 inches (21.59 cm by 27.94 cm).

These dimensions refer to the North American standard paper size known as "Letter" or "US Letter." It is commonly used for various purposes such as printing documents, letters, and reports. The dimensions are based on the traditional imperial measurement system, specifically the United States customary units. The longer side of the paper is known as the "letter" or "long" side, while the shorter side is called the "legal" or "short" side.

The 8.5 by 11 inch size provides a versatile and widely accepted format for printing and documentation needs.

$\sqrt[4]{81} -8(\sqrt[3]{216} )+15(\sqrt[5]{32} )+\sqrt{225}$

Answers

$\sqrt[4]{81} -8( \sqrt[3]{216}) +15( \sqrt[5]{32}) +\sqrt{225}$ when simplified gives 0

What are Indices?

Indices are small number that tells us how many times a term has been multiplied by itself. Indices are also the power or exponent which is raised to a number or a variable.

How to determine this

$\sqrt[4]{81} -8( \sqrt[3]{216}) +15( \sqrt[5]{32}) +\sqrt{225}$

When all of then are perfect square

$\sqrt[4]{81}$= 3 * 3 *3 *3

$\sqrt[3]{216}$ = 6 * 6 * 6

$\sqrt[2]{32}$ = 2 * 2 * 2 * 2 * 2

$\sqrt{225}$ = 15 * 15

Therefore,

3 - 8(6) + 15(2) + 15

3 - 48 + 30 + 15

By collecting like terms

3 + 30 + 15 - 48

48 - 48

= 0

Tenths

0 * 10 = 0

ones

8 * 1 = 8

Tenths = 2 * 1/10 = 2/10 = 1/5 = 0.2

Hundredths = 3/100 = 0.03

Thousandths = 1/1000 = 0.001

So we simply sum all these to get the number itself as follows

500 + 8 + 0.2 + 0.03 + 0.001 = 508.231

2. 12 × s - 48 = 12 × 4 - 48 = 48 - 48 = 0

4. 2 × s × s × s × s = 2 × 4 × 4 × 4 × 4 = 2 × 64 = 128
5. (s + 6) × (s + 2) = (4 + 6) × (4 + 2) = 10 × 6 = 60

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 cards per week. Sarah has 233 baseball cards and collects 5 cards per week. After about how many weeks will Ryan and Sarah have the same number of cards?

Answers

Answer:

About 17 weeks

Step-by-step explanation:

Given

Ryan:

$Initial = 150$

$Additional = 10$ (weekly)

Sarah:

$Initial = 233$

$Additional = 5$ (weekly)

Required

Determine the number of weeks they have the same cards

Represent the number of weeks with w:

For Both individuals, number of card at any given week is:

$Initial + Additional * w$

So,

For Ryan, the expression is:

$150 + 10 * w$

$150 + 10w$

For Sarah, the expression is:

$233 + 5 * w$

$233 + 5 w$

To determine the number of weeks, we have to equate both equations:

$150 + 10w= 233 + 5 w$

Collect Like Terms

$10w - 5w = 233 - 150$

$5w = 83$

Solve for w

$w = 83/5$

$w = 16.6$

16.6 implies about 17 weeks, because 16.6 approximates to 17

Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks

on a standardized test with a normal distribution, the mean was 64.3 and the standard deviation was 5.4. what is the best approximation of the percent of scores that fell between 58.9 and 75.1?

Answers

the best approximation of the percent of scores that fell between 58.9 and 75.1 is 4.

The mathematical average of a group of two or more numbers is called the mean. There are two different sorts of means that can be calculated: the arithmetic mean and the geometric mean. The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of integers in the set.

Find the difference between these two figures and the mean, divide it by the standard deviation of 5.4, and you will know how many standard deviations 75.1 and 61.5 are above and below the mean:

(75.1−64.3)/5.4

=2sd

According to the empirical rule, 95% of data are within two standard deviations of the mean.

So, the answer is 4.

Answers

For confidence interval: support of the association rule A to B is 0.5 and the confidence of the association rule A to B is 0.5.

For Support and confidence of the association rule A - B

To determine the support and the confidence of the association rule A → B, where A = {1, }, B = {1}, we use the formulas given below:

Support(A → B) = frequency of (A, B) / N

Confidence(A → B) = frequency of (A, B) / frequency of A

where N is the number of transactions in the database.

To find the frequency of (A, B) and the frequency of A.

Thus Frequency of (A, B) = 1

Since there is only one transaction in the database where both A and B occur, the frequency of (A, B) is 1.

Frequency of A = 2

The itemset {1, } occurs in two transactions T₁ and T₂.

Hence, the frequency of A is 2.

Which equation of a straight line is parallel to the line 4y= 3x +5? A) y= 3x +5. B) 4y= 3x-1. C) 3y= 4x +5. D) -4y= 3x+5. E) 4y= x + 5

Answers

The given line has a slope of 3/4. Therefore, the equation of a line parallel to it will also have a slope of 3/4. option C

Among the options provided, the equation that has a slope of 3/4 is option C) 3y = 4x + 5. By rearranging this equation to slope-intercept form (y = mx + b), we get y = (4/3)x + 5/3, which clearly has a slope of 4/3 or 3/4 when expressed as a fraction. Hence, option C) is the correct equation of a line parallel to 4y = 3x + 5.

To further explain, when two lines are parallel, they have the same slope but different y-intercepts. In the given options, option A) y = 3x + 5 has the same slope but the same y-intercept as the given line, so it is not parallel to it. Option B) 4y = 3x - 1 has a different slope,

so it is not parallel. Option D) -4y = 3x + 5 has the same slope but a different sign, so it is not parallel. Option E) 4y = x + 5 has a different slope, so it is not parallel. Thus, option C) 3y = 4x + 5 is the only equation that satisfies the requirement of being parallel to the given line.

Assume you've just received a bonus at work of $3,875. You deposit that money in the bank today, where it will earn interest at a rate of 6% per year. How much money will you have in the account after 3 years? Enter your answer in terms of dollars and cents, rounded to 2 decimals, and without the dollar sign. That means, for example, that if your answer is $127.5678, you must enter 127.57

Answers

To calculate the amount of money you will have in the account after 3 years with an interest rate of 6% per year, we can use the formula for compound interest:

A = P(1 + r)^n

Where:

A = the final amount

P = the principal amount (initial deposit)

r = the interest rate per period (in decimal form)

n = the number of periods

In this case:

P = $3,875

r = 6% per year, or 0.06 (in decimal form)

n = 3 years

Substituting the values into the formula:

A = 3,875(1 + 0.06)^3

Calculating:

A = 3,875(1.06)^3

A = 3,875(1.191016)

A ≈ 4,614.76

After rounding to two decimal places, you will have approximately $4,614.76 in the account after 3 years.

Answers

The standard deviation of the proportion of times that it lands point up out of 100 tosses be, 16

Given, the chance that a certain type of thumbtack lands point up when you toss it in the air is 80%.

we have to find the standard deviation of the proportion of the given data that it lands point up out of 100 tosses.

Number of trials be, 100

probability of success be, 80/100 = 0.8

On using the formula of Standard deviation, we get

then add
17 + 20 = 37 :)) hope this helps

(you multiply by 2 because on a sheet a paper there 4 sides on the paper and two for each number)

37 is your awnser :))

Answer:

The length of the piece of paper diagonally is 13.1 inches.

Step-by-step explanation:

First, I decided to imagine the diagonal line as the hypotenuse of a right triangle, and use the Pythagorean Theorem, a^2 + b^2 = c^2.

In this case, it would be 8.5^2 + 10^2 = ?^2.

8.5^2 = 72.25, and 10^2 = 100.

72.25 + 100 = 172.25, which equals c^2.

However, since 172.25 inches is c squared and not just c, we need to find the square root of it, which is 13.1, rounded to the nearest tenth.

find the measure of MO if MN and NO is 4.6

Answers

The measure of length MO is 9.2 units

How to determine the measure of MO?

From the question, the given parameters are:

MN and NO is 4.6

The above statement means that

MN = 4.6

NO = 4.6

Next, we assume that the points M, N and O are collinear points.

This means that the points are on the same line

So, we have the following equation

MO = MN + NO

Substitute the known values in the above equation

MO = 4.6 + 4.6

Evaluate the sum

MO = 9.2

Hence, the measure of length MO is 9.2 units
