What is unitary method?

Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit. Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity

Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.

Here unitary method is used

The scale on a map is stated as 1: 100 000

So 1 cm on the map is equivalent to 100000 cm on the ground

8 cm on the map is equivalent to 100000 [tex]\times[/tex] 8 cm on the ground

8 cm on the map is equivalent to 800000 cm on the ground

8 cm on the map is equivalent to [tex]\frac{800000}{1000 \times 100}[/tex] km on the ground

8 cm on the map is equivalent to 8 km on the ground

Answer:

  b. Square -2

Step-by-step explanation:

You want to know the first step in evaluating 1/2 |2x² - 3| for x = -2.

The Order of Operations tells you the first step is to evaluate expressions inside the innermost grouping symbols. Here, that means you want to evaluate the expression 2x² - 3.

Once you have identified that expression, you start by evaluating terms with exponents. That term here is x². When x=-2, the first step is to square -2.

__

Additional comment

After you get x² = 4, then you evaluate the product 2(4) = 8, and then the difference 8 -3 = 5. Then the absolute value is determined |5| = 5, and finally the product with 1/2: (1/2)(5) = 5/2.

The correct option is option b. It can be obtained by following the order of operation BODMAS.

What is the order of operation?
To solve any mathematical expression, the BODMAS rule is used. The full form of BODMAS is Bracket Order DIvision Multiplication Addition Subtraction. It can be simplified as, to solve the Mathematica expression first open all brackets, then powers, then division, then multiplication, then addition, and finally subtraction.

Now, consider the following expression:

1/2 |2x² - 3|

Now, substitute -2 for x in the above expression.

1/2 |2(-2)² - 3|

In the above expression there is no bracket hence the next step is solve power of -2.

Hence, the first step of solving the above expression is square -2.

Hence, the correct option is b. It can be obtained by following the order of operation BODMAS.

Answer: I think the answer is 71.98

Step-by-step explanation:

Answer: -8

Step-by-step explanation:

The line has a slope of 1/8, so the x increases by 8 for every 1 the y increases, and vice versa for a decrease.

The difference between the x coordinates 8 and -8 is 16. We then need to divide this by 8, because the x increases by 8 for every 1 the y increases, and we need to find the increase/decrease in y.

16/8 = 2

We need to subtract 2 from -6, giving us our answer, -8.

An integer is a number that includes both negative and positive numbers, including zero. It has no decimal or fractional parts. Here are a few examples of integers: -5, 0, 1, 5, 8, 97, and 3,043

P(n) is a condition that is true for P(0), P(1), and P(2), but P(3k) is true when P(k) is true for all numbers k0.

P(n) is thus not always true for all nonnegative integers n because 4 is not a multiple of 3.

For example, consider the property P(n): "n is 0 or 1, or n is a multiple of 3." Then P(0), P(1), and P(2) are trivially true, however, P(3k) is true for all numbers k because 3k is a multiple of 3. However, P(4) is false because 4 is not a multiple of 3.

Melitta found out that if she walks really fast during her morning exercise, she can cover 2 1/4 miles in 3/4 of an hour.

Mellita is walking with a coverage of 2.8  miles per hour. We simply need to know how far she covers in an hour to calculate her walking speed in miles per hour.

Time taken to complete 2~1/4 miles is 3/4 of an hour. This is the time she can beat, so we have to find for the remaining 1/4th half of 2~1/4 miles i.e

Miles she can cover in 1/4 of hour = 1/4 * 2~1/4

    = 1/4  * 9/4

    = 9/16 miles.

Now, Add this to the miles that she can cover, i.e 2~1/4

A big sample that should the experimenter take from the population is 256 and if the standard deviation and the width of the confidence interval are both doubled then the sample is also 256.

In the given question,

The confidence level = 99%

Given width = 0.5

Standard deviation of resistance([tex]\sigma[/tex])= 1.55

We have to find a big sample that should the experimenter take from the population and what happens if the standard deviation and the width of the confidence interval are both doubled.

The formula to find the a big sample that should the experimenter take from the population is

Margin of error(ME) [tex]=z_{\alpha /2}\frac{\sigma}{\sqrt{n}}[/tex]

So n [tex]=(z_{\alpha /2}\frac{\sigma}{\text{ME}})^2[/tex]

where n=sample size

We firstly find the value of ME and [tex]z_{\alpha /2}[/tex].

Firstly finding the value of ME.

ME=Width/2

ME=0.5/2

ME=0.25

Now finding the value of [tex]z_{\alpha /2}[/tex].

Te given interval is 99%=99/100=0.99

The value of [tex]\alpha[/tex] =1−0.99

The value of [tex]\alpha[/tex] =0.01

Then the value of [tex]\alpha /2[/tex] = 0.01/2 = 0.005

From the standard table of z

[tex]z_{0.005}[/tex] =2.58

Now putting in the value in formula of sample size.

n[tex]=(2.58\times\frac{1.55}{0.25})^2[/tex]

Simplifying

n=(3.999/0.25)^2

n=(15.996)^2

n=255.87

n≈256

Hence, the sample that the experimenter take from the population is 256.

Now we have to find the sample size if the standard deviation and the width of the confidence interval are both doubled.

The new values,

Standard deviation of resistance([tex]\sigma[/tex])= 2×1.55

Standard deviation of resistance([tex]\sigma[/tex])= 3.1

width = 2×0.5

width = 1

Now the value of ME.

ME=1/2

ME=0.5

The z value is remain same.

Now putting in the value in formula of sample size.

n[tex]=(2.58\times\frac{3.1}{0.5})^2[/tex]

Simplifying

n=(7.998/0.5)^2

n=(15.996)^2

n=255.87

n≈256

Hence, if the standard deviation and the width of the confidence interval are both doubled then the sample size is 256.

The final balance after 1 year with initial value $1000 if the interest is compounded quarterly will be $1215.5

What is compound interest?

Compound interest is computed as interest on the initial principal plus any accrued interest from prior periods. The power of compound interest is the creation of "interest on interest."

We are given that she initially invested $1000 and that she get 5% and interest is compounded quaterly.

After 3 months the interest will be

I = 1000*(5/100)

I = 50

So the total amount becomes

$1050 after 3 months

Now after 3 months again 5% interest will be credited

Hence the amount becomes

I1 = 1050*(5/100)

I1 = 52.5

Hence the total amount becomes

1102.5 after 6 months

After 9 months the interest will be

I2 = 1102.5*(5/100)

I2 = 55.12

Hence the total amount becomes

$1157.62 after 9 months

After 1 years the interest will be

I3 = 1157.62*(5/100)

I3 = 57.88

Hence the total amount becomes $1215.5

The perpendicular bisector is a line that bisects the line segment into two equal halves and forms a right angle with the line segment.

What is a Perpendicular bisector?
A line that divides another line segment into two equal halves by intersecting it perpendicularly is known as a perpendicular bisector. A rule, compass, and pencil can be used to draw a perpendicular bisector. When two lines cross at right angles or 90 degrees, they are said to be perpendicular to one another. A line that splits a line into two equally sized parts is known as a bisector. A line segment's perpendicular bisector suggests that it meets the segment at a 90-degree angle and splits it into two equal halves.
So, In the given question, We can say that A bisector that divides the line segment into two parts is called a perpendicular bisector;
We can also, find the proof of it: as: It divides AB into two equal halves or bisects it. It makes right angles with (or is perpendicular to) AB.
Every point in the perpendicular bisector is equidistant from points A and B.A ruler and compass are needed. The process for creating a line segment's perpendicular bisector is as follows:

Draw the first segment of the line PQ.

Step 2: Set the compass to a length that is a little longer than half of PQ's length.

Draw arcs above and below the line by positioning the compass pointer at point P in step 3.

Step 4: Set the compass pointer at point Q while maintaining the same length. Draw two arcs above and below the line, in the same manner, maintaining the compass's pointer at Q.
Hence, The perpendicular bisector is a line that bisects the line segment into two equal halves and forms a right angle with the line segment
