Set of Sides which will form a right angled triangle is ( 3 , 4 , 5 )

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.

This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

For a triangle to be Right Angled , It should obey the Pythagoras Theorem

[tex]c^{2} = a^{2}+b^{2}[/tex]

c = hypotenuse

a = perpendicular side

b = base

Hence

if c = 5 , a = 3 and b = 4

Then

[tex]c^{2} = a^{2}+b^{2}[/tex]

[tex]5^{2}= 3^{2}+4^{2}[/tex]

25 = 3 + 16

25 = 25

So

It obeys the Pythagoras Theorem

95% of the time confidence intervals like this capture the true average time between a felony.

The average of the true ranges throughout the given period is known as the average true range (ATR). ATR calculates volatility by accounting for any gaps in price movement. 14 periods, which can be intraday, daily, weekly, or monthly, are typically used in the ATR calculation. Utilize a shorter average, such as 2 to 10 periods, to gauge recent volatility. Use 20 to 50 periods for volatility over longer time spans.

The standard error is decreasing on increasing number of Sample.

What is the standard error?

The population mean and sample mean are likely to deviate from one another, and the standard error of the mean, or simply standard error, shows how likely this is.

                    If a study were to be repeated using fresh samples drawn from a single population, it would be possible to calculate how much the sample mean would change.

The standard error is represented by a σ because it is a standard deviation. The subscript (M) indicates that the standard error in question is the standard error of the mean.

Now we will get the standard error for the following situations:

(a) σ_M = 12/√4 = 6

(b) σ_M = 12/√16 = 3

(c) σ_M = 12/√64 = 1.5

Hence from here, we can conclude that the standard error is decreasing on increasing number of Sample.

Red books are 8 and blue books are 6.

The smallest unit of measurement is the inch (or inches, in plural). A foot is made up of twelve inches. In the metric system, one inch is equivalent to 2.54 cm. When measuring shorter distances, such the breadth of an eraser or the length of a pencil, inches are employed.

Give conditions

Total books = 11

Red book height = 1 inches

Blue book height = 2 inches

Total height = 14 inches

We assume that

8 red books and 3 blue books = 11 books { first condition is satisfied}

In inches case:

8 * 1 = 8 { red book height 1 inches}

3 * 2 = 6 {blue book height 2 inches}

total height = 8 +6 = 14 inches {second condition is satisfied}

The values of the angles are m∠ A = 112.5°, m∠ B = 67.5°, m∠ C = 67.5°, and m ∠D = 112.5°

Considering the regular octagon, the sum of angles in an octagon is 1080°. This implies each angle in the octagon will be 1080/8 = 135°

Thus, you can label the angle as shown in the image attached

c + m<A + 135° = 360°  (the sum of angle at a point is 360°)

Since c = m<A (identical sides)

m<A + m<A + 135° = 360°

2 m<A = 360-135

m<A = 225/2 = 112.5°

m<B + m<A = 180°  (Between two parallel lines, consecutive interior angles add up to 180°)

m<B + 112.5° = 180°

m<B = 180-112.5 = 67.5°

m<C = <B    (base angles of isosceles trapezoids are equal)

m<C = 67.5°

What is the domain of a function?

The domain of a function is the set of all conceivable values that are acceptable as inputs, or alternatively, it can be interpreted as the full set of potential values for independent variables. The denominator of the fraction is not equal to zero, and the digit under the square root bracket is positive, which is an indicator of the domain.

Let us first take any 2 coordinates of the function, say (-143,-2) and (0,-71).

let us take the slope of these 2 points,

[tex]m=\frac{x_{2}-x_{1} }{y_{2}- y_{1} } \\m=\frac{-71+143}{0+2} \\m=\frac{72}{2} \\m=36[/tex]

A system of equations are 9x+7y=77 and 3x+5y=49. Therefore, cost to rent each chair is $1.75 and cost to rent each table is $8.75.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

a) From the table, first costumer brought 9 chairs and 7 tables per $77

Second costumer brought 3 chairs and 5 tables per $49

Let x be the cost (in dollars) to rent a chair

Let y be the cost (in dollars) to rent a table

Here, 9x+7y=77 --------(I)

3x+5y=49 --------(II)

b) Multiply equation (II) by 3

9x+15y=147 --------(III)

Subtract equation (I) from (III), we get

9x+15y-(9x+7y)=147-77

⇒ 8y=70

⇒ y=8.75

Substitute y=8.75 in (I), we get

9x+7×8.75=77

⇒ 9x+61.25=77

⇒ 9x=77-61.25

⇒ 9x=15.75

A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.

As per the given question, we have

Here P = $1900 , r = 3.5%, and T = 1 years

The total payback = P× r/100 × T + P

The  quantity of hydrocortisone powder, in g, should be entered on the compounding record as 56.7 g

Generally, To determine the quantity of hydrocortisone powder to be used in the compounding of this prescription, you will need to know the percentage of the final preparation that will be made up of hydrocortisone.

Since the prescription calls for a 1:1 mixture of hydrocortisone cream and Aquaphor, and the final quantity is to be 4 oz, each component will make up half of the final preparation. Therefore, the final preparation will be 50% hydrocortisone.

To determine the quantity of hydrocortisone powder needed, you will need to multiply the final desired quantity of the preparation by the percentage of the preparation that is made up of hydrocortisone. In this case, the desired final quantity is 4 oz, and the preparation is 50% hydrocortisone, so the calculation is:

4 oz * 50% = 2 oz

Since there are 28.35 grams in an ounce, the total quantity of hydrocortisone powder needed in grams is:

2 oz * 28.35 g/oz = 56.7 g

Therefore, you should enter a quantity of 56.7 g of hydrocortisone powder on the compounding record for this prescription.

The total distance in miles Mars travels throughout its complete orbit will be 888 × 10⁶ miles.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, If Mars travels at 24,126 meters per second in orbit around the Sun and takes 1.88 earth years to complete its orbit,

First, we have to convert the unit from earth year to second obtained as,

1.88 earth year=  59287680 second

As we know that the distance is the multiplication of the speed and the time

Distance = speed × Time

Distance =24,126 m/sec ×  59287680 second

Distance = 1.4 × 10¹² m

If 1 meter consists of 0,000621371 miles, the obtained distance is in miles.

1 metere = 0,000621371 miles

1.4 × 10¹² m=888 × 10⁶ miles

he data in the table appears to be modeled by the function f(x) = -x^2 + 2.

To see this, let's plug in the values for x in the table and see if the resulting values for f(x) match the values in the table:

f(-2) = (-2)^2 + 2 = 4 - 2 = 2

f(-1) = (-1)^2 + 2 = 1 - 1 = 0

f(0) = 0^2 + 2 = 2

f(1) = 1^2 + 2 = 1 + 2 = 3

We can see that the resulting values for f(x) match the values in the table, so f(x) = -x^2 + 2 is a function that could represent the data.
