b. in 35 years Value = 32000*(1-16.3%)^35 = 63.17

the expected value for the given data set will be 0.423

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, a data set gives prizes and probabilities of winning (on a single $1 ticket) for the Multi-State Powerball lottery.

We have to determine the expected value of winnings when buying one ticket. This can be computed using the expected value formula.

Recall the formula for the expected value E for events A and B whose probabilities of occurring are P(A) and P(B), respectively:

E  = (P(A)×value for A)+(P(B)×value for B)

​Using the formula above and extending it to 99 events yields:

E(x) = (1/ 292, 201,338 * 30,000,000) + (1 / 11,688,053 * 1,000,000) + (1/913,129 * 50,000) + (1/ 36,525 * 100) + (1/14,494 * 100) + (1/ 580 *7) + (1 /701 * 7) + (1/92 * 4) + (1/ 38 * 4)

The total tax that the business paid on its purchases only was 769720.25.

In order to pay for general public institutions, goods, and activities, local, state, and federal governments must collect mandated payments or charges from citizens and corporations.

We must first figure out the complete cost of the goods in order to determine the total taxable income the corporation paid

The cost of the 16,000 network routers is:

16,000 units x $79.25/unit = $1,268,000

The cost of the 12,000 wireless LAN adapters is:

12,000 units x $129.95/unit = $1,559,400

The cost of the 13,500 computer boards is:

13,500 units x $229.15/unit = $3,092,025

The total cost of all purchases is:

$1,268,000 + $1,559,400 + $3,092,025 = $5,919,425

To calculate the total tax amount, we need to multiply the total cost by the tax rate. Assuming a tax rate of 13%, the total tax amount is:

$5,919,425 x 0.13 = $768,527.25

Therefore, the total tax amount that the company paid on their purchases only is $768,527.25, rounded off to 2 decimal places.

Answer:

$500.000 × 0.08 = $40,000

$40,000/12 = $3.333.33

Step-by-step explanation:

El interés simple mensual se puede calcular como una fracción del interés anual. Para calcular el interés simple mensual, primero debemos calcular el interés anual y luego dividirlo entre 12 para obtener el interés mensual.

El interés anual se puede calcular multiplicando el capital por la tasa de interés:

$500,000 × 0.08 = $40,000

Luego, para obtener el interés simple mensual, dividimos el interés anual por 12:

$40,000 / 12 = $3,333.33

Por lo tanto, un capital de $500,000 al 8% de interés simple generará $3,333.33 de interés simple mensual.

Answer:

50

Step-by-step explanation:

To find the number of students, we can use the formula: average = (sum of marks) / (number of students).

Substituting the given values: 40 = 2000 / number of students

Solving for the number of students: number of students = 2000 / 40 = 50

So, there are 50 students in the series.

The solution is, the minute hand will be 87.7 degrees ahead of the hour hand.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

Let's call the current position of the hour hand H and the current position of the minute hand M.

At the start, we have H = 0 and M = -20 degrees.

After 18 minutes, the minute hand will have moved 18 * 6 = 108 degrees, while the hour hand will have moved 18 * (6/60) = 0.3 degrees.

So the new position of the minute hand is M + 108 = 88 degrees,

and the new position of the hour hand is H + 0.3 = 0.3 degrees.

Therefore, the minute hand will be 88 - 0.3 = 87.7 degrees ahead of the hour hand.

Step-by-step explanation:

a) Find the angular speed of the blade in radians per minute:

The formula for angular speed is given by:

ω = 2 * π * f

where f is the frequency of rotation in revolutions per minute, and π is approximately equal to 3.14159.

Plugging in the values, we get:

ω = 2 * 3.14159 * 4300 revolutions per minute

ω = 26,957.1 radians per minute

Rounding to three decimal places, the answer is:

ω = 26,957.1 radians per minute = 26,957.1 radians/minute

b) Find the linear speed of the saw teeth (in inches per minute) as they contact the wood being cut:

The formula for linear speed (v) is given by:

v = ω * r

where ω is the angular speed in radians per minute, and r is the radius of the blade (half of the diameter).

Plugging in the values, we get:

v = 26,957.1 radians/minute * 4.125 inches

v = 111,542.7 inches per minute

Rounding to one decimal place, the answer is:

v = 111,542.7 inches per minute = 111,543 inches/minute

In a unit rate, the denominator is always 1.

The regression equation is linear in the explained and explanatory variables.

In order for Ordinary Least Squares (OLS) estimates to be unbiased, the regression equation must be linear in both the explained and explanatory variables. This means that the relationship between the dependent variable (what is being explained) and the independent variables (what is being used to explain the dependent variable) must be linear. This is important because it ensures that the estimated coefficients of the regression equation accurately reflect the true relationship between the variables. Additionally, the error term must have an expected value of 0, given any value of the explanatory variable, and have the same variance given any value of the explanatory variable. This ensures that the estimated coefficients do not suffer from bias and that the OLS estimates are unbiased.

What are functions?

In mathematics, a function is an expression, rule, or law that specifies the relationship between an independent variable x and a dependent variable y.

y and x are related in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x). In other words, for the same x value, there cannot be more than one value for f(x).

We are given two functions, f(x) and g(x).

Their graphs are also given.

We are asked to solve the following questions using the given graphs.

1) (f o g) (2) = f( g(2) )

To solve this we have to first start with inner functions.

g(2) = value of y when x = 2  

    From the g(x) graph it is given that g(2) = 2 when x = 2

Now we substitute this in f( g(2) )

i.e f(2) = value of y when x = 2 = 0

From the f(x) graph it is given that f(2) = 0 when x = 2.

So (f o g) (2) = 0

2) (g o f) (2) = g( f(2) )

  f(2) = 0 ( as mentioned above)

Substituting,

 g( f(2) = g (0) = 4

So (g o f) (2) = 4

Therefore the value of the functions are (f o g) (2) = 0 and

In Geometry and trigonometry, an aspect is a shape made up of two rays, referred to as the angle's sides, that converge at a center point termed as the angle's vertex. Two rays can create an angle in the region where they are arranged. Additionally, when two planes collide, an angle is created. Dihedral angles are what they are called. An angle is a possible structure for two rays or lines with only a common end in planar geometry. The English term "angle" originated from the Latin word "angulus," which meaning "horn." The vertex is the common endpoint of the opposite rays, also known as the side of the angle.

The surface area of figure is 784 ft² and the volume of the figure is 576 ft³.

What is volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

The shape created by Jeff is a cube + square pyramid.

The height of square pyramid is = 3 ft

The sides of cube = 8 ft

The formula for volume of cube = (side)³

Volume of cube = (8)³

Volume of cube = 512 ft³

The formula for volume of square pyramid = (base)² × height / 3

Volume of square pyramid = (8)² × 3/3

Volume of square pyramid = 64 × 1

Volume of square pyramid = 64 ft³

Total volume of the figure -

Volume of cube + Volume of square pyramid

Total volume = 512 + 64

Total volume = 576 ft³

The formula for surface area of cube = 6(side)²

Surface Area of cube = 6 × (8)²

Surface Area of cube = 6 × 64

Surface Area of cube = 384 ft²

The formula for surface area of square pyramid = 6(side)²

Surface Area of square pyramid = (side)² + 2(side) √[{(side)²/4} + (height)²]

Surface Area of square pyramid = (8)² + 2(8) √[{(8)²/4} + (3)²]

Surface Area of square pyramid = 64 + 16 √[{64/4} + 9]

Surface Area of square pyramid = 80 √[16 + 9]

Surface Area of square pyramid = 80 √25

Surface Area of square pyramid = 80 × 5

Surface Area of square pyramid = 400 ft²

Total surface area of the figure -

Surface Area of cube + Surface Area of square pyramid

Total Surface Area = 384 + 400

Total Surface Area = 784 ft²

Therefore, the volume and surface area of the figure is 576 ft³ and 784 ft² respectively.
