Step-by-step explanation:

To find the expected value, we need to multiply each possible outcome by its probability and add up the results.The probability of drawing a ball with $1 is 5/10 = 0.5.

The probability of drawing a ball with $2 is 2/10 = 0.2.

The probability of drawing a ball with $30 is 3/10 = 0.3.

The expected value is:

(0.5 * 1) + (0.2 * 2) + (0.3 * 30) = 0.5 + 0.4 + 9 = 9.9

However, the person paid $10 to play, so we need to subtract that from the expected value:9.9 - 10 = -0.1

Therefore, the expected value of this game is -$0.10. Answer choice (A) is correct.

A Sporting goods company makes footballs with an alligator logo. Of the 8,750 footballs produced in one week, 77 were defective. If the company produces 37500 footballs in one month , how many do you predict will be defective ?

The company can expect to earn $5 per product sold if they offer a warranty, compared to an expected loss of $13 per product sold if they do not offer a warranty. It is a profitable decision for the company to offer the warranty.

In a binomial probability distribution, the number of "Successes" in a series of n experiments is represented as either success/yes/true/one (probability p) or failure/no/false/zero (probability q = 1 p), depending on the outcome's boolean value.

Assuming that the failure of the flagship product follows a binomial distribution with a probability of 1% of failure within 2 years of purchase, let's calculate the expected cost to the company without a warranty and with the warranty.

Without the warranty, the expected cost to the company is given by:

Expected cost without warranty = 0.01 x $1300 = $13

With the warranty, the expected cost to the company is given by:

Expected cost with warranty = $5 - (0.99 x $0) = $5

Therefore, the company can expect to earn $5 per product sold if they offer a warranty, compared to an expected loss of $13 per product sold if they do not offer a warranty. It is a profitable decision for the company to offer the warranty.

To simulate this scenario in Python.

Here's a possible implementation:

import random

# Set the seed number

random.seed(77)

# Initialize the starting amount and the number of bets

amount = 18

num_bets = 0

# Loop until the player runs out of money

while amount >= 1:

   # Increment the number of bets

   num_bets += 1

   # Check if the player wins

   if random.random() < 0.0028:

          # Otherwise, the player loses $1

   else:

# Report the total number of bets

print(f"Total number of bets: {num_bets}")

In this implementation, we use the random module in Python to simulate the outcome of each bet.

We set the seed number to 77 to ensure that the results are reproducible.

We initialize the starting amount to $18 and the number of bets to 0. We then loop until the player runs out of money (i.e., the amount variable is less than $1).

Inside the loop, we increment the number of bets by 1 and simulate the outcome of the bet using random.

random() which returns a random float between 0 and 1.

If the random number is less than the winning probability of 0.0028, the player wins $20 and we add that to the amount variable.

Answer:

Step-by-step explanation:

The Conjugate Roots Theorem states that imaginary roots come in pairs. If -8i is a root of the polynomial, then so is +8i.

If both -8i and +8i are factors, we rewrite them as (x + 8i) and (x - 8i) in factored form. Since imaginary terms aren't accepted, you can FOIL these to get a quadratic with no imaginary terms.

x2 - 8ix + 8ix - 64i2

Simplify. Replace i2 with -1 because √-1 = i

x2 - 64(-1)

x2 + 64

The quadratic x2 + 64 has roots -8i and 8i. You can use the quadratic formula to verify this.

Now, let's tackle the rest of the polynomial. If x2 + 64 is a factor of the polynomial

x4 + 10x3 + 85x2 + 640x + 1344, divide it out to see what is left. I will use long division of polynomials. Note, I am using the square root symbol as a division symbol.

x2 + 10x + 21

x2 + 64 √ (x4 + 10x3 + 85x2 + 640x + 1344)

x4 + 64x2

_____________

10x3 + 21x2

10x3 + 640x

__________

21x2 +1344

21x2 + 1344

___________

0

There is no remainder, meaning x2 + 64 went in evenly. The quotient left when we divide out x2 + 64 from

x4 + 10x3 + 85x2 + 640x + 1344 is x2 + 10x + 21. Factor the quotient to get (x + 7)(x + 3).

x4 + 10x3 + 85x2 + 640x + 1344 = (x2 + 64)(x + 7)(x + 3)

You can check this factored form by FOILing out, and you should get the original polynomial.

A rectangular pyramid is a three-layered strong item that comprises of a rectangular base and four three-sided faces that meet at a typical point, called the summit.

In the figure below is a cuboid and upside is Square Pyramid;

Surface area of cuboid = 2 (l×h + l×w+ h×w)

Surface area of cuboid = 2 (6×3 + 6×3+ 3×3)  = 2 (18+18+9)

Surface area of cuboid = 90 unit²

The slant height is the hypotenuse of a right triangle whose height is 3 inches and half the base of the triangular (3/2 = 1.5 inches). Using the Pythagorean theorem,

slant height = [tex]\sqrt{3^2 + 1.5^2}[/tex]   [tex]= \sqrt{11.25}[/tex]

slant height = 3.35 unit

Surface Area of a Square Pyramid = base² + 2×base×slant height

Surface Area of a Square Pyramid = 3² + 2×3×3.35

Surface Area of a Square Pyramid = 9 + 20.1

The answer of the given question based on the plotting graph , the steps are given below .

An inequality is a statement that compares two values or expressions and indicates that one is greater than, less than, or equal to the other. Inequalities can be solved or simplified using various algebraic techniques, such as adding, subtracting, multiplying, or dividing both sides by the same quantity, or factoring and finding the roots of the expressions

To plot the inequality 4x - 5y ≤ -15, you can follow these steps:

4x - 5y ≤ -15

-5y ≤ -4x - 15

y ≥ (4/5)x + 3

Let's choose x = 0 and x = 5.

When x = 0: y = (4/5)(0) + 3 = 3, so one point is (0, 3).

When x = 5: y = (4/5)(5) + 3 = 7, so another point is (5, 7).

Plot these two points and draw  straight line through them.

4x - 5y ≤ -15

4(0) - 5(0) ≤ -15

0 ≤ -15

Since this is not true, the point (0,0) is not in the region that satisfies the inequality. Shade the region above the boundary line to show the region that satisfies the inequality.

This is untrue since the point (0,0) is not located in the area where the inequality is satisfied. To highlight the area that satisfies the inequality, shade the area above the boundary line.

An inequality is a comparison that shows that one value or expression is larger than, less than, or equal to another. Different algebraic methods, such as adding, subtracting, multiplying, or dividing both sides by the same amount, or factoring and determining the roots of the equations, can be used to resolve or simplify inequalities.

Plotting the inequality 4x - 5y ≤-15 can be done by doing the following:

To solve for y, rearrange the inequality first:

4x - 5y ≤ -15

-5y ≤ -4x - 15

y ≥ (4/5)x + 3

You are then provided with the boundary line's equation. Plot two points on a graph, then draw a straight line through them to represent this line. You can use the equation to determine the values of y that correspond to any two x values to plot the line.

Let's choose x = 0 and x = 5.

When x = 0: y = (4/5)(0) + 3 = 3, so one point is (0, 3).

When x = 5: y = (4/5)(5) + 3 = 7, so another point is (5, 7).

Plot these two spots and a line should be drawn directly between them.

Now select a point that is not on the border line to shade the area that satisfies the inequality. (0, 0) is the simplest position to select. In the inequality, replace the x and y values of this point.

4x - 5y ≤ -15

4(0) - 5(0) ≤ -15

0 ≤ -15

Since this is untrue, the point (0,0) is not located in the area where the inequality is satisfied. To highlight the area that satisfies the inequality, shade the area above the boundary line.

The time taken by Amy to travel to the place was t = 4 hours.

A measure of average speed is the amount of distance travelled in a given amount of time. It is determined by dividing the overall mileage by the overall time required to cover that mileage.

In physics and other sciences, average speed is frequently employed to describe how objects move. For instance, it is possible to estimate how long it will take to go a certain distance or assess a car's fuel economy by looking at its average speed over a given distance. By dividing the whole distance travelled by the total time required, average speed may also be used to characterise the speed of an object that is moving at various speeds at different points along its path.

Let the time taken to get back = t + 1.

Now, it took one hour less time to get there thus time = t.

Now, average speed is given as:

average speed = total distance / total time

Substituting the values:

50 km/h = d / t

d = 50t  .........(1)

40 km/h = d / (t + 1)

d = 40(t + 1)......(2)

Setting the value of d as equal we have:

50t = 40(t + 1)

so, all answers about a prism (rectangular bottom shape) are automatically wrong.

well, the outermost point of the rectangle is 8 points away from the x-axis. when we rotate this rectangle, that attribute remains, of course. and every point on the side surface of the resulting cylinder has the same distance from the central x-axis : 8.

so, the radius is 8.

Answer:

invest full 800$

Step-by-step explanation:

I would advise my friend to invest the full $800 in his new IRA. While buying a couple of pairs of sneakers may provide immediate satisfaction, investing in an IRA can have long-term financial benefits.

If we assume an average annual return of 8% for his IRA, then the $800 investment would grow to approximately $4,536 after 30 years. On the other hand, if he only invests $400 and spends the remaining $400 on sneakers, then the investment would only grow to approximately $2,268 after 30 years.

Thus, by investing the full $800, my friend would have a potential gain of over $2,268 compared to if he only invested $400. Furthermore, investing in an IRA can provide tax benefits and potentially reduce his taxable income, providing additional financial benefits.In summary, while it may be tempting to use some of the money for immediate gratification, investing the full $800 in an IRA can provide long-term financial benefits that outweigh the short-term satisfaction of purchasing a couple of pairs of sneakers.
