What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be n

The number n is a whole number

The number 2n is greater than 20

So ,

2n > 20

Divide by 2 on both sides , we get

n > 10

And , the number 5n < 60

Divide by 5 on both sides , we get

n < 12

So , 10 < n < 12

Therefore , the number is greater than 10 but less than 12 , so the whole number is 11

Hence , the number n is 11

Step-by-step explanation:

run me my points .

Step-by-step explanation:

The like terms on the list are given as follows:

\(\sqrt{2}, -3\sqrt{2}, 5\sqrt{2}, \sqrt{50}\)

Like terms are terms that share these two features:

If two terms are like terms, then they can be either added or subtracted.

In the case the terms are roots, they have the same root.

The square root of 50 is given as follows:

\(\sqrt{50} = \sqrt{2 \times 25} = 5\sqrt{2}\)

Hence the like terms are given as follows:

\(\sqrt{2}, -3\sqrt{2}, 5\sqrt{2}, \sqrt{50}\)

There are no terms with 3 or 5 on the root, hence the other two terms have no like terms.

Answer:

The number of deliveries that are predicted to be made to homes during a week with 50 deliveries to business is 87 deliveries

Step-by-step explanation:

The data categorization are;

The number of home deliveries = x

The number of delivery to businesses = y

The line of best fit is y = 0.555·x + 1.629

The number of deliveries that would be made to homes when 50 deliveries are made to businesses is found as follows;

We substitute y = 50 in the line of best fit to get;

50 = 0.555·x + 1.629 =

50 - 1.629 = 0.555·x

0.555·x = 48.371

x = 48.371/0.555= 87.155

Therefore, since we are dealing with deliveries, we approximate to the nearest whole number delivery which is 87 deliveries.

Answer: Length = 17 ft

Concept:

Here, we need to know how to find the perimeter of a rectangle.

Perimeter (rectangle) = 2 (l + w)

l = length

w = width

If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.

Solve:

**Disclaimer** I assume that the length is [3 feet longer than twice its width] because a [yard] would not use length to measure it. If it was, then you may refer to my answer. If it was not, then you may tell me and I will redo it.

Let x be the width

Let 2x + 3 be the length

Given information

Perimeter = 48 ft

width = x

length = 2x + 3

Given expression deducted from the question

Perimeter = 2 (l + w)

Substitute values into the expression

48 = 2 (2x + 3 + x)

Combine like terms in the parentheses

48 = 2 (2x + x + 3)

48 = 2 (3x + 3)

Expand parentheses and apply the distributive property

48 = 2 · 3x + 2 · 3

48 = 6x + 6

Subtract 6 on both sides

48 - 6 = 6x + 6 - 6

42 = 6x

Divide 6 on both sides

42 / 6 = 6x / 6

x = 7

Find the value of length

Length = 2x + 3 = 2(7) + 3 = 14 + 3 = \(\boxed{17}\)

The correct answer is c. Inferential Statistics.

Inferential statistics is the branch of statistics that allows for drawing conclusions about a population based on the information collected from a sample. When conducting research or surveys, it is often impractical or impossible to collect data from an entire population.

Instead, a representative sample is chosen, and inferential statistics are used to make inferences or predictions about the larger population. By analyzing the characteristics and patterns observed within the sample, inferential statistics enable researchers to make generalizations or draw conclusions about the population as a whole.

This process involves applying various statistical techniques, such as hypothesis testing and confidence intervals, to estimate population parameters and assess the reliability of the conclusions. Magnitude statistics, central tendency, and effect size are important concepts in statistics, but they do not specifically address the ability to draw population-level conclusions from sample data.

Magnitude statistics focuses on the size of the effect or relationship between variables, central tendency measures summarize the central values of a dataset, and effect size quantifies the strength of an effect or relationship.

The value of x , y and z in the parallel line is 50 degrees.

When parallel lines are crossed by a transversal line, angle relationships are formed such as vertically opposite angles, alternate interior angles, alternate exterior angles, adjacent angles, corresponding angles etc.

Therefore, let's use the angle relationships to find the angle, x, y and z as follows:

Therefore,

x = 360 - 310(sum of angles in a point)

x = 50 degrees

Therefore,

x = y(alternate interior angles)

Alternate interior angles are congruent.

Hence,

y = 50 degrees

Therefore,

x = z(alternate interior angles)

Answer:

the population variance is 2 and the population standard deviation is approximately 1.41.

Step-by-step explanation:

To calculate the variance and standard deviation of a population, you can use the following formulas:

Population variance = (Σ(x - μ)²) / N

Population standard deviation = √(Σ(x - μ)² / N)

Where:

Σ is the sum of

x is each individual score in the population

μ is the population mean

N is the number of scores in the population

To begin, we need to find the population mean (μ):

μ = (6 + 2 + 3 + 0 + 4) / 5 = 3

Next, we can calculate the variance:

Population variance = ((6-3)² + (2-3)² + (3-3)² + (0-3)² + (4-3)²) / 5

Population variance = (9 + 1 + 0 + 9 + 1) / 5

Population variance = 2

Finally, we can calculate the standard deviation:

Population standard deviation = √((6-3)² + (2-3)² + (3-3)² + (0-3)² + (4-3)²) / 5

Population standard deviation = √(9 + 1 + 0 + 9 + 1) / 5

Population standard deviation = √2

Therefore, the population variance is 2 and the population standard deviation is approximately 1.41.

The variance of the given set of scores is 4 and the standard deviation is 2. Both are measures of how spread out the data is in statistics. The variance is calculated by acquiring the average squared deviation from the mean, while the standard deviation is the square root of the variance.

This is a question about the notions of variance and standard deviation in statistics. Variance is a measure of how spread out the numbers in a data set are. Standard deviation, on the other hand, is the square root of the variance, indicating the amount of deviation (or variation) you can expect in your data.

Step-by-step explanation:

The formula for margin of error for a 95% confidence interval is: Margin of Error = (Critical value) * (Standard deviation of the statistic)In the given situation, the proportion of green dragons was 15 out of 100. Therefore, the proportion of non-green dragons would be (100-15) = 85 out of 100.

Now, let's use the formula of standard deviation to determine the standard deviation of the statistic (p-hat) for the green dragons, which is given by:p-hat = 15/100 = 0.15q-hat = 1 - p-hat = 0.85n = 100Using the formula for standard deviation of the statistic, we get:√[(p-hat * q-hat) / n] = √[(0.15 * 0.85) / 100] = 0.0393Now, let's find the critical value using a normal distribution table or calculator for 95% confidence interval, which is given by:z* = 1.96 (rounded to two decimal places)Therefore, the margin of error for a 95% confidence interval is:Margin of Error = z* * (Standard deviation of the statistic)= 1.96 * 0.0393= 0.077. A dragonologist has hired a statistician to help him determine the proportion of green dragons in comparison to all other dragons in North West China. Using a simple random sampling (SRS) tactic, the statistician has discovered that there are 15 green dragons out of 100. We are required to calculate the margin of error for a 95% confidence interval. The formula for margin of error for a 95% confidence interval is as follows:Margin of Error = (Critical value) * (Standard deviation of the statistic)Firstly, we need to calculate the standard deviation of the statistic for the green dragons, which is given by:p-hat = 15/100 = 0.15q-hat = 1 - p-hat = 0.85n = 100 Using the formula for standard deviation of the statistic, we get:√[(p-hat * q-hat) / n] = √[(0.15 * 0.85) / 100] = 0.0393 Next, we need to find the critical value using a normal distribution table or calculator for 95% confidence interval, which is given by:z* = 1.96 (rounded to two decimal places)Therefore, the margin of error for a 95% confidence interval is:Margin of Error = z* * (Standard deviation of the statistic)= 1.96 * 0.0393= 0.077Hence, the margin of error for a 95% confidence interval is 0.077.

The margin of error is a measure of the uncertainty of a statistic (such as a mean or proportion) for a given sample. It represents the degree of inaccuracy that we can expect from our sample, given that the same sample is drawn repeatedly. The margin of error for a 95% confidence interval can be calculated using the formula Margin of Error = z* * (Standard deviation of the statistic), where z* is the critical value for the desired confidence level and standard deviation of the statistic is calculated from the sample data. In the given situation, we have calculated the margin of error for a 95% confidence interval to be 0.077 using the formula.

The robot moves in the positive direction along a straight line so that after t minutes its distance is s=6t^4 feet from the origin. (a) Find the average velocity of the robot over intervals 2, 4. We have the following data: Initial time, t₁ = 2 min.

Final time, t₂ = 4 min.The distance from the origin is given by s = 6t^4Therefore, s₁ = s(2) = 6(2^4) = 6(16) = 96 feet s₂ = s(4) = 6(4^4) = 6(256) = 1536 feet

We can find the average velocity of the robot over the interval 2, 4 as follows: Average velocity = (s₂ - s₁) / (t₂ - t₁)Average velocity = (1536 - 96) / (4 - 2)Average velocity = 1440 / 2Average velocity = 720 feet per minute(b) Find the instantaneous velocity at t=2.To find the instantaneous velocity at t = 2 min, we need to take the derivative of the distance function with respect to time.

Answer:

Degrees = Radians x 180/π

or

Degrees = 57.2958  x radians

Step-by-step explanation:

1 radian = 180/π degrees

1 radian = 57.2958 degrees

Multiply radians by this factor of 57.2958  to get the equivalent measure in degrees

π radians = 180°

2π radians = 360° which is the number of degrees in a circle

For anything greater than 2π radians you will have to subtract 360°

For example, 7 radians using the formula is 7 x (57.2958  ) ≈ 401.07°

But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

\(f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28\)

So it's x^2+3x-28

Answer:

1400m^2

Step-by-step explanation:

Solution,

Let the breadth of the rectangle be x m, then the length of the rectangle will be x+5 m,

Now,

Perimeter of the rectangle=2(l+b)

150=2(x+5+x)

150=2(2x+5)

150=4x+10

150-10=4x

140=4x

140/4=x

35=x

So, the breadth of the rectangle=35 m

and length=(35+5)m=40m

Again,

Area of the rectangle=l×b

=40m×35m

=1400 m^2

I hope it helped U

stay safe stay happy

Answer: Area= 1400\(meter^{2}\)

Step-by-step explanation:

ok  so  we can assume the

breadth=X

so, length = X+5 (because the length is 5 meters more than the breadth)

perimeter= 150 meters

the formula of the perimeter of a rectangle = 2 x ( Length + Breadth)

so now if we put the values,

2 * ( X+5 +X) = 150 ( because 150 is the perimeter)

2 * (2X + 5) = 150 (the value became 2x because when we add two variables with the same value it will be written as 2(any variable)).

now we multiply  2 with both sides

so ( 2 * 2X) + (2 * 5)

hence, 4X + 10 = 150

now we will solve the equation,

4X= 150 -10 (because we did transposal the signs will change from "+" to "-")

4x= 140

again with the transposal (when we write a number with a variable it shows that it means the number multiplied by the variable in this case it is 4 multiplied by X ) so when we transpose we will have to divide because multiplication turns into division while transposing

so now,

X= 140÷4

which is equal to 35

so finally X = 35

so as we have written in the beginning breadth= X

and LENGTH= X+5

so now we have found X

BREADTH= 35

LENGTH= 40 (because 35+5 is 40)

now we have to find area the formula for finding the area is LENGTH×BREADTH

so, 40 × 35 = 1400

now we put the unit which is square meters also known as \(m^{2}\)

so there is your final answer 1400\(m^{2}\)
