1 3/5÷1/4

In order to determine which is the probability for reading 4 books, you consider that the sum of all probabilities must be equal to 1.0. In that sense, you know that the unknow value of the probability distribution for x = 4 can be calculate as follow:

- Add up all known values of the probability distribution

0.23 + 0.27 + 0.18 + 0.07 = 0.75

- Next, you subtract the previous result to 1.0:

1.0 - 0.75 =0.25

The previous result is the value of the probability distribution for x = 4.

Hence, the probability of reading 4 books is 0.25, which is equivalent to 25.0%.

Answer:

solve for 6x+8

Answer:

x = 3

Step-by-step explanation:

Since ∠ P and ∠ S are congruent then the triangle is isosceles and

PT = TS , substitute values

7x + 4 = 5x + 10 ( subtract 5x from both sides )

2x + 4 = 10 ( subtract 4 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Answer:

2x + 15

Step-by-step explanation:

When you subtract an expression from another expression, it will be on the right side of the subtraction sign.

(4x + 9) - (2x - 6)

First, let's distribute the negative sign.

(4x + 9) - 2x + 6

Now combine like terms.

4x - 2x + 9 + 6

2x + 15

This is the fully simplified expression.

8                       8,000

In Science and Mathematics, a conversion factor can be defined as a number that is used to convert a number in one set of units to another, either by dividing or multiplying.

Generally speaking, there are one (1) kilometer in one thousand (1,000) meters. This ultimately implies that, a proportion or ratio for the conversion of kilometer to meters would be written as follows;

Conversion:

1 kilometer = 1,000 meters

2 kilometer = 2,000 meters

3 kilometer = 3,000 meters

4 kilometer = 4,000 meters

5 kilometer = 5,000 meters

6 kilometer = 6,000 meters

7 kilometer = 7,000 meters

8 kilometer = 8,000 meters

The image of the dilation of P is (12, 21)

From the question, we have the following parameters that can be used in our computation:

P = (4, 7)

The expression D3 means that

The point P is dilated by a scale factor of 3

Using the above as a guide, we have the following:

D3P = P * 3

Substitute the known values in the above equation, so, we have the following representation

D3P = (4, 7) * 3

Evaluate

D3P = (12, 21)

Hence, the image of the dilation of P is (12, 21)

Answer:

h = 452.5 ft

Step-by-step explanation:

Angle of elevation from P to top of the pole = 65°

Horizontal distance between the pole and point P = 21 ft

By Applying tan rule in the given triangle ABP,

tan(∠APB) = \(\frac{AB}{PB}\)

tan(65°) = \(\frac{h}{21}\)

h = 21[tan(65°)]

h = 452.491

h ≈ 452.5 ft

Therefore, height of the pole is 452.5 ft.

The value of angle x is 133 degree

And the equation of line be of the form,

⇒  y - y₁ = 133(x - x₁)

In the given line,

one angle is of 47 degree

And other is x degree

To find the value of x,

Since we know that,

The angle  of line is 180 degree.

Therefore,

⇒ x + 47 = 180

⇒         x = 133 degree

Therefore slope of this line be 133 degree

Now let this line is  passing through (x₁, y₁)

Hence,

The equation of  line be,

⇒ y - y₁ = (slope)(x - x₁)

⇒  y - y₁ = 133(x - x₁)

\(\sqrt[3]{729x^{18} }\)\((27x^9)^{2/3}\) when simplified is \(9x^{6}\)

Indices are the power or exponent which is raised to a number or a variable. It shows the number of times a given number has to be multiplied. It says that a particular number (or base) is to be multiplied by itself, the number of times equal to the index raised to it.

How to determine this

Using the rule of Indices,

An index in the form of a fraction can be represented as the radical form.

\(a^{x/y} = y\sqrt{a} ^{x}\)

\((27x^9)^{2/3}\)

= \(\sqrt[3]{(27x^{9} } )^{2}\)

Open bracket,

= \(\sqrt[3]{27^{2}x^{9*2} }\)

= \(\sqrt[3]{729x^{18} }\)

Using the rule again

\(a^{x/y} = y\sqrt{a} ^{x}\)

= \(729x^{1/3} * x^{18 * 1/3}\)

= \(\sqrt[3]{729} * x^{6}\)

= \(9 * x^{6}\)

= \(9x^{6}\)

Answer:

m(arc AC) = 72°

m(arc BD) = 108°

m∠DEB = 90°

Step-by-step explanation:

Ratio of the measure of arc AC, arc BC, arc BD and arc AD = 4 : 2 : 6 : 8

Since, m(arc AC) + m(arc CB) + m(arc BD) + m(arc AD) = 360°

By the property of ratio,

Measure of arc AC = \(\frac{4}{4+2+6+8}\times (360^0)\)

                               = \(\frac{4\times 360}{20}\)

                               = 72°

Measure of arc BD = \(\frac{6}{4+2+6+8}\times (360^0)\)

                               = \(\frac{6\times 360}{20}\)

                               = 108°

Measure of ∠DEB = \(\frac{1}{2}m(arcAC + arc BD)\)

                              = \(\frac{1}{2}(72+108)\)

                              = 90°

If you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

To calculate the Social Security tax, we need to know the tax rate for Social Security and the taxable wages. Let's assume the Social Security tax rate is 6.2% for both the employee and the employer.

Given that your taxable wages for Social Security purposes are $1,100, and your previous taxable wages are $102,000, we can determine the Social Security tax amount.

First, we need to calculate the Social Security tax on the previous taxable wages of $102,000. Multiply $102,000 by 6.2% (0.062) to find the Social Security tax for that amount:

Social Security tax = $102,000 x 0.062 = $6,324

Next, we calculate the Social Security tax on the current taxable wages of $1,100. Multiply $1,100 by 6.2% to find the tax amount:

Social Security tax = $1,100 x 0.062 = $68.20

Therefore, if you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

Step-by-step explanation:

Assuming your "altitude" is the height of the prism--the distance between bases, the lateral area is the sum of the areas of the six rectangular faces. Each of those has an area of ...

  (8 in)(6 in) = 48 in^2

so the 6 of them will have an area of ...

  lateral area = 6×48 in^2 = 288 in^2

_____

Comment on nomenclature

'Altitude' is usually associated with the height of a triangle. In the case of a regular polygon, the 'altitude' of a triangular section of the polygon is called the 'apothem', and is often designated using the letter 'a'. If the polygon is regular, the apothem can be calculated from the side length and the number of sides, but it is often given in problems involving area, perimeter, and/or volume.

The distance between the parallel bases of a prism is often referred to as the prism height or length. The use of the word 'altitude' is confusing in this case.

Since the lateral area is the product of the perimeter of the base and the distance between bases, we have to assume that your 'altitude' refers to the distance between bases. Otherwise, there is not sufficient information to work the problem.
