Answer:
what is all that?!
In American roulette, you may bet whether the number that comes up is odd (or even) on a ball landing on one of 38 sectors numbered 1 through 36 and including 0 and 00. (Remember that 0 and 00 do not count as either odd or even.) The wager pays even money; that is, if you win, you get whatever you bet, and if you lose, you lose that same amount. What is your expected value for this bet?
The expected value is ((18/37) x (2 x wager [we will receive the wager back and the winnings])) + ((19/37) x 0)
What is American roulette?
Guessing on which number on the wheel ball will come to rest is the objective of American Roulette. Every number contains the same chances as any other number of coming up on each spin (that is winning number on any spin has no effect on the outcome of next spin). The best chance of payout is provided by an outside bet. The possible outcomes of the game of roulette is covered by 'outside bets'. With the higher winning chances, the payout is not going to be incredibly generous(it's only 1:1 for bets like odd or even that covers almost like half the wheel).
Expected value is calculated by adding all the different possible outcomes multiplied by their probabilities.
So, in this case (0.5 x $2) + (0.5 x $1).
For specific example it would be determined by the number of options on a roulette wheel (generally 37).
So winning on this bet in 18 outcomes (the even numbers) and losing on 19 outcomes (the odd numbers + 0).
Putting it all together, the expected value is ((18/37) x (2 x wager [we will receive the wager back and the winnings])) + ((19/37) x 0).

Consider the following system of two linear equations:
4y + 3x = 0
4y - x = 16
What is the point of intersection?
Answer: The two lines intersect at (-4,3)
Step-by-step explanation:
So our first step would be to turn both of these into standard slope-intercept form.
1.)
4y + 3x = 0
4y = -3x
y = -3/4x
2.)
4y - x = 16
4y = x + 16
y = 1/4x + 4
Now that we have our 2 equations, y = -3/4x and y = 1/4x + 4 we can graph them to get an intersection at (-4,3)

Answer:
2·2·2·2 = 16
Step-by-step explanation:
everytime a number is raised by another, that means you are going to multiply the base number times itself as many times as the exponents tells you. this is a little but tricky to explain, so let me give you some examples:
2² → in this case the base number is 2 and the exponent is 2 as well, so you will multiply 2 times itself, 2 times:
2² = 2 · 2 = 4
2³ → in this case the base number is 2 and the exponent is 3, so you will multiply 2 times itself, 3 times:
2³ = 2 · 2 · 2 = 8
In the question asked, 2 is being raised by 4, so you will multiply 2 times itself, 4 times:
2^4 = 2·2·2·2 = 16
the same format will be used regardless of the base number and the exponent

d) How many three-digit numbers greater than 330 can be formed from the digits 0, 1, 2, 3, 4, 5, and 6?(
The question is incomplete. Here is the complete question.
(a) How many three-digit numbers can be formed from the digits 0,1,2,3,4,5 and 6, if each digit can be used only once?
(b) How many of these are odd numbers?
(c) How many are greater than 330?
Answer: (a) 180
(b) 75
(c) 105
Step-by-step explanation:
(a) In the group, there are 7 digits. A three-digit number can not start with zero, otherwise, it will be a 2-digit number. So:
For the hundreds position, there are 6 choices.
For the tens position, since the digit can be used only once, there are 6 choices.
For the unit position, there are 5 choices.
The total three-digit number formed is: 6*6*5 = 180
(b) To form an odd number, the unit position must be an odd digit, then:
unit position has 3 choices;
hundreds position has 5 choices;
tens position has 5 remaining choices.
The total three-digit odd number is: 3*5*5 = 75
(c) The number formed must be greater than 330, so:
If the number start with a 3, to be greater, there are 3 other choices (4, 5 and 6), so Tens position has 3 choices and Unit position has 5 choices.
Total number is: 3*5 = 15
Another possibility is the number starts with a digit bigger than 3 and so, there are 3 choices.
Tens position has 6 choices;
Unit position has 5 choices;
Total possibilities are: 3*6*5 = 90
The total number of ways a three-digit number is greater than 330 is:
90 + 15 = 105

-20 cm-
30 cm
Find the volume of
The total surface area of the metal used to make the rubbish bin is approximately 2199 cm² to the nearest cm².
What is the total surface area of the cylinder?
To calculate the total surface area of the metal used for the cylindrical rubbish bin, we need to find the area of the base and the lateral surface area.
The base of the cylindrical bin is a circle with a diameter of 20 cm, so its radius is 10 cm.
Therefore, the area of the base is:
Area of base = π × radius²
Area of base = π × 10²
Area of base = 100π ≈ 314.16 cm²
The lateral surface area of the cylinder can be found using the formula:
Lateral surface area = height × circumference of the base
The circumference of the base can be found using the formula:
Circumference = π × diameter
Circumference = π × 20
Circumference = 20π ≈ 62.83 cm
So, the lateral surface area of the cylinder is:
Lateral surface area = 30 × 62.83
Lateral surface area ≈ 1884.9 cm²
Therefore, the total surface area of the metal used is:
Total surface area = area of base + lateral surface area
Total surface area ≈ 314.16 + 1884.9
Total surface area ≈ 2199.06 cm²

wenty-five randomly selected students were asked the number of movies they watched the previous week. the results are as follows:
The sample mean of the number of movies watched by 25 students is 2.8 and the approximate sample standard deviation is 1.15.
(a) The sample mean X can be calculated by taking the average of the number of movies watched by all 25 students.
Step 1: Sum up the number of movies watched by all 25 students:
\(0 * 1 + 1 * 2 + 2 * 4 + 3 * 10 + 4 * 6 + 3 * 2 = 0 + 2 + 8 + 30 + 24 + 6 = 70\)
Step 2: Divide the sum from Step 1 by the number of students (25):
70 / 25 = 2.8
So the sample mean X = 2.8
(b) The sample standard deviation s can be calculated using the formula:
\(s = \sqrt{\frac{ \sum(X - X_{mean})^2}{(n-1)} }\)
Where \(X_{mean}\) is the sample mean, n is the sample size, and Σ represents the sum of all values.
Step 1: Calculate \((X - X_{mean})^2\)for each data point and sum up the values:
\((0 - 2.8)^2 * 1 + (1 - 2.8)^2 * 2 + (2 - 2.8)^2 * 4 + (3 - 2.8)^2 * 10 + (4 - 2.8)^2 * 6 + (3 - 2.8)^2 * 2\\ = 7.84 + 3.24 + 0.64 + 9.6 + 1.44 + 7.84\\ = 31.36\)
Step 2: Divide the sum from Step 1 by (n - 1) = 24:
31.36 / 24 = 1.31
Step 3: Take the square root of the result from Step 2:
\(\sqrt{1.31} = 1.15\)
So the approximate sample standard deviation s = 1.15 (rounded to two decimal places).

Lauder Company had fixed costs of $282,500, variable costs of $645,000, and actual sales amounted to $1,100,000. If the company has a break-even point at $750,000 in sales revenue.a. determine the margin of safety expressed in dollars
b. determine the margin of safety expressed as a percentage of sales. Enter percentage amount as a whole number.
____%
c. Determine contribution margin ratio
_____%
d. Determine the operating income
$______
The Operating income is $172,500.
To calculate the margin of safety, contribution margin ratio, and operating income, we need to use the given information.
a. Margin of Safety:
Margin of Safety = Actual Sales - Break-even Sales
Given that the break-even point is at $750,000 in sales revenue and actual sales are $1,100,000, we can calculate the margin of safety:
Margin of Safety = $1,100,000 - $750,000 = $350,000
Therefore, the margin of safety is $350,000.
b. Margin of Safety as a Percentage of Sales:
Margin of Safety Percentage = (Margin of Safety / Actual Sales) * 100
Using the values from the previous calculations:
Margin of Safety Percentage = ($350,000 / $1,100,000) * 100 = 31.82%
Therefore, the margin of safety expressed as a percentage of sales is approximately 31.82%.
c. Contribution Margin Ratio:
Contribution Margin Ratio = (Contribution Margin / Sales) * 100
To calculate the contribution margin, we need to subtract variable costs from sales:
Contribution Margin = Sales - Variable Costs = $1,100,000 - $645,000 = $455,000
Using the values, we can calculate the contribution margin ratio:
Contribution Margin Ratio = ($455,000 / $1,100,000) * 100 = 41.36%
Therefore, the contribution margin ratio is approximately 41.36%.
d. Operating Income:
Operating Income = Sales - Variable Costs - Fixed Costs
Using the values provided:
Operating Income = $1,100,000 - $645,000 - $282,500 = $172,500
Therefore, the operating income is $172,500.
