if you purchased one ticket, your expected gross winnings are $0.36.
what is gross winnings ?
Gross winnings refer to the total amount of money won before any taxes or fees are deducted. In other words, it is the total amount of money won by an individual in a lottery or other type of game of chance, without taking into account any deductions that may be made
In the given question,
To calculate the expected gross winnings, we need to multiply the probability of winning each prize by the value of the prize and then add up these values.
First, let's find the probability of winning each prize:
First prize: There is only one first prize, and there are 15,000 tickets sold, so the probability of winning the first prize is 1/15,000.
Second prize: There are two second prizes, so the probability of winning a second prize is 2/15,000.
Third prize: There are three third prizes, so the probability of winning a third prize is 3/15,000.
Now we can calculate the expected gross winnings:
First prize: The probability of winning the first prize is 1/15,000, and the value of the prize is $3,000, so the expected value of the first prize is (1/15,000) x $3,000 = $0.20.
Second prize: The probability of winning a second prize is 2/15,000, and the value of each prize is $750, so the expected value of a second prize is (2/15,000) x $750 = $0.10.
Third prize: The probability of winning a third prize is 3/15,000, and the value of each prize is $300, so the expected value of a third prize is (3/15,000) x $300 = $0.06.
Now we can add up these value to find the total expected gross winnings:
$0.20 + $0.10 + $0.06 = $0.36
Therefore, if you purchased one ticket, your expected gross winnings are $0.36.

The surface area of the composite figure is 944 cm².
What is the surface area of a cuboid?
Surface area of a cuboid is (lb+lh+bh) where l,b,h are length, breadth and height of the cuboid.
To find the surface area of the composite figure, we need to calculate the surface area of both cuboids and then subtract the area of any faces that are shared by both cuboids.
Given dimension of first cuboid is 14 cm × 8 cm × 2 cm and dimension of the second cuboid is 8 cm × 6 cm × 4 cm.
Surface area of the first cuboid:
Area of the top and bottom faces = 2(14 x 8) = 224 cm²
Area of the front and back faces = 2(14 x 2) = 28 cm²
Area of the left and right faces = 2(8 x 2) = 32 cm²
Total surface area of the first cuboid = 2(224) + 2(28) + 2(32) = 576 cm²
Surface area of the second cuboid:
Area of the top and bottom faces = 2(8 x 6) = 96 cm²
Area of the front and back faces = 2(8 x 4) = 64 cm²
Area of the left and right faces = 2(6 x 4) = 48 cm²
Total surface area of the second cuboid = 2(96) + 2(64) + 2(48) = 416 cm²
Now we need to identify the faces that are shared by both cuboids. The first cuboid has a bottom face that is the same size as the top face of the second cuboid (6 x 4). The surface area of this shared face is 48 cm².
Therefore, the surface area of the composite figure is total surface area of the first cuboid + Total surface area of the second cuboid - Area of shared face
= 576 + 416 - 48
= 944 cm²
So the surface area of the composite figure is 944 cm².

The amount of annual rainfall for each lake during that time period is shown by the graphs, Annual Rainfall Amounts Lake Warbler Lake Mockingbird + + + 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 Rainfall (inches) 2 Which statement correctly describes the spreads of the data distributions for the lakes? The spreads of the data distributions are about the same for both lakes. B The spread of the data distribution for Lake Mockingbird is about 40% greater than the spread for Lake Warbler. The spread of the data distribution for Lake Mockingbird is 3 inches less than the spread of the data distribution for Lake Warbler. The spread of the data distribution for Lake Mockingbird is 5 inches greater than the spread of the data distribution at Lake Warbler. 3 Which statement is NOT true about the data? A The spreads for the first 25% of the data distributions for both lakes are equal. B The distribution for Lake Mockingbird shows a center that is 3 inches greater than the center of the distribution for Lake Warbler. The interquartile range of the data distribution for Lake Warbler is about 60% of the interquartile range for Lake Mockingbird. The data distributions for both lakes appear to be skewed left.
"The spread of the data distribution for Lake Mockingbird is 5 inches bigger than the spread of the data distribution for Lake Warbler," is the answer to question 2.
The graphs do not support this statement since the difference in spread between the two lakes is not represented as 5 inches. The right answer to question 1 is B: "The spread of the data distribution for Lake Mockingbird is approximately 40% higher than the spread for Lake Warbler." This is due to the fact that the data distribution of the Lake Mockingbird is around 60 inches (from 5 to 65), whereas the data distribution of the Lake Warbler is approximately 43 inches (from 2 to 45). The difference between the two ranges is approximately 60 - 43 = 17. inches. From 43 to 60, the percentage rise is around 39.5%, which is close to 40%. The correct answer to question 3 is B: "The distribution of Lake Mockingbird reveals a center that is 3 inches greater than the distribution of Lake Warbler." This assertion is false since the graphs do not show the center of each distribution and cannot be established with the information supplied.

A license plate consists of a 3-digit number. If a license plate is selected at random, what is the probability that the last digit will be an odd number?
Answer:
There are 10 possible digits that could appear on the license plate: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Half of these digits (1, 3, 5, 7, and 9) are odd.
Since there are three digits on the license plate, there are 10x10x10 = 1000 possible license plates.
To find the probability that the last digit is odd, we need to find the number of license plates where the last digit is odd and divide by the total number of possible license plates:
Number of license plates where last digit is odd = 10x10x5 = 500 (since there are 5 odd digits to choose from for the last digit)
Total number of possible license plates = 10x10x10 = 1000
So the probability of selecting a license plate at random where the last digit is an odd number is:
500/1000 = 0.5 or 50%

Step-by-step explanation:
There are 10 red, 10 blue, 10 green, and 10 yellow marbles in bag. A student pulled a marble, recorded the color, and placed the marble back in the bag. The table below lists the frequency of each color pulled during the experiment after 40 trials.
Outcome Frequency
red 8
blue 12
green 9
yellow 11
Compare the theoretical probability and experimental probability of pulling a blue marble from the bag.
The theoretical probability, P(blue), is 25%, and the experimental probability is 30%.
The theoretical probability, P(blue), is 50%, and the experimental probability is 12%.
The theoretical probability, P(blue), is 50%, and the experimental probability is 30%.
The theoretical probability, P(blue), is 30%, and the experimental probability is 25%.
The correct answer is: The theoretical probability, P(blue), is 25%, and the experimental probability is 30%
What is theoretical probability?Theoretical probability is a concept in mathematics and statistics that refers to the likelihood or chance of an event occurring based on mathematical reasoning and analysis. Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes in a given situation or experiment. It is based on the assumption that each outcome is equally likely to occur.
According to the given informationThe theoretical probability of pulling a blue marble from the bag is the number of blue marbles divided by the total number of marbles:
P(blue) = 10/40 = 1/4 = 25%
The experimental probability of pulling a blue marble from the bag is the number of times a blue marble was pulled divided by the total number of trials:
Experimental probability of pulling a blue marble = 12/40 = 3/10 = 30%
We can see that the experimental probability of pulling a blue marble is slightly higher than the theoretical probability, which is expected since this is based on a limited number of trials and chance variation can occur. However, as the number of trials increases, the experimental probability should converge to the theoretical probability.
The correct answer is: The theoretical probability, P(blue), is 25%, and the experimental probability is 30%.

What is the linear inequality of the graph below?
The linear inequality for the shaded region with slope [tex]-4[/tex] is:
[tex]y < -4x+4[/tex]
What is linear inequality?In mathematics, a linear inequality is an inequality involving a linear function in one or more variables. It describes a region in the coordinate plane that satisfies the inequality.
In mathematics, the slope is a measure of the steepness of a line. It describes how much a line rises or falls as we move from left to right along it.
According to the given information
To write the linear inequality for the graph passing through points [tex](0,4)[/tex] and [tex](1,0)[/tex], we need to find the equation of the line first.
The slope of the line passing through these two points is:
[tex]m =(y_{2} -y_{1} )/(x_{2} -x_{1} )\\ = (0-4)/(1-0)\\ = -4[/tex]
Using the slope-intercept form of a linear equation, [tex]y = mx +b[/tex], where m is the slope and b is the y-intercept, we can find the equation of the line passing through these two points:
[tex]y = -4x+4[/tex]
Now, to write the linear inequality for this line, we need to determine which side of the line is shaded. We can use the test point [tex](0,0)[/tex] to check which side of the line contains the solutions to the inequality.
If we plug in [tex](0,0)[/tex] into the equation [tex]y = -4x+4[/tex], we get:
[tex]0= -4(0) +4\\0 = 4[/tex]
Since [tex]0[/tex] is not less than [tex]4[/tex], the point [tex](0,0)[/tex] is not a solution to the inequality. Therefore, we need to shade the side of the line that does not contain the origin [tex](0,0)[/tex].
The linear inequality for the shaded region is:
[tex]y < -4x +4[/tex]
Therefore any point below the line [tex]y < -4x +4[/tex] satisfies this inequality.

What is right angle triangle?A right-angled triangle, also known as a right triangle, is a type of triangle that has one of its angles measuring exactly 90 degrees. The other two angles in a right triangle are acute angles, which means they are less than 90 degrees. The side opposite to the right angle is called the hypotenuse, and it is the longest side of the triangle. The other two sides of the right triangle are called legs, and they are adjacent to the right angle. The Pythagorean theorem, which states that the sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of its hypotenuse, is a fundamental concept in the study of right triangles. Right triangles have many practical applications in geometry, trigonometry, and physics.
In a right triangle, the sum of the measures of the two acute angles is always 90 degrees. Therefore, the third angle in this triangle is:
90 - 34 = 56 degrees
Now, we can use the trigonometric ratios to find the length of the side x.
We know that the tangent of an angle is equal to the length of the opposite side divided by the length of the adjacent side. Therefore:
[tex]tan(34) = x/18[/tex]
To solve for x, we can multiply both sides by 18:
[tex]18 tan(34) = x[/tex]
Using a calculator, we can find that:
18 tan (34) ≈ 10.76.

A 25% orange juice drink is mixed with a 100% orange juice drink. The function f(x) = (4)(1.0)+z(0.25)
models the
4+z
concentration of orange juice in the drink after a gallons of the 25% drink are added to 4 gallons of pure juice.
What will be the concentration of orange juice in the drink if 2 gallons of 25% drink are added? Give the answer as a percent
but do not include the percent sign (%).
To solve the problem, we need to use the given function f(x) = 4 + z(0.25) where x is the amount of 25% orange juice drink added and z is the amount of 100% orange juice drink added.
We know that initially 4 gallons of pure juice are present. So, the total amount of juice in the mixture is 4 + x gallons.
When we add 2 gallons of 25% orange juice drink, x = 2 and z = 0. So, using the function f(x), we get:
f(2) = 4 + z(0.25)
= 4 + 0(0.25)
= 4
Therefore, the concentration of orange juice in the drink after adding 2 gallons of 25% orange juice drink is 4%, expressed as a percent but without the percent sign.

different-size rectangular cages as shown below.
Small cage: floor area of 12 square feet
Medium cage: floor area of 24 square feet
Large cage: floor area of 36 square feet
Alex needs to find a possible length and width for the floor of each
size cage. What is a possible length, width, and perimeter for each
cage's floor?
The possible length, width, and perimeter for Small cage's floor is 4 feet, 3 feet and 14 feet respectively; for Medium cage's floor is 12 feet, 2 feet and 28 feet respectively and for Large cage's floor is 18 feet, 2 feet and 40 feet respectively.
What is perimeter?
Whether it be a two-dimensional shape or a one-dimensional length, a perimeter is a closed path that contains, surrounds, or delineates it.
We are given the floor areas of each cage.
For Small cage:
Area is given as 12 square feet which is a product of length and width.
So, here length can be 4 feet and width can be 3 feet.
Now, we get the perimeter as
⇒ Perimeter = 2 * (Length + width)
⇒ Perimeter = 2 * (4 + 3)
⇒ Perimeter = 2 * 7
⇒ Perimeter = 14 feet
For Medium cage:
Area is given as 24 square feet which is a product of length and width.
So, here length can be 12 feet and width can be 2 feet.
Now, we get the perimeter as
⇒ Perimeter = 2 * (12 + 2)
⇒ Perimeter = 2 * (14)
⇒ Perimeter = 28 feet
For Large cage:
Area is given as 36 square feet which is a product of length and width.
So, here length can be 18 feet and width can be 2 feet.
Now, we get the perimeter as
⇒ Perimeter = 2 * (18 + 2)
⇒ Perimeter = 2 * (20)
⇒ Perimeter = 40 feet
Hence, the required solution has been obtained but there are many other combinations possible.

Step-by-step explanation:
which one of the equations below could be used as a line of best fit to approximate the data in the scatter plot?
There are many tools available to calculate the line of best fit, including Excel, R, and Python. These tools provide the best equation that approximates the data
To determine which equation could be used as a line of best fit to approximate the data in a scatter plot, we need to look for the equation that closely follows the general trend of the data. The line of best fit is the straight line that best represents the data on the graph.
One common method for finding the line of best fit is through linear regression analysis. This involves calculating the slope and intercept of the line that best fits the data. The equation for a line is y = mx + b, where m is the slope and b is the y-intercept.
In general, the equation that could be used as a line of best fit depends on the data on the scatter plot. However, we can determine the best equation by looking at the trend of the data. If the data shows a positive trend, we need to choose an equation with a positive slope. If the data shows a negative trend, we need to choose an equation with a negative slope.
To determine the equation of the line of best fit for a specific scatter plot, we need to use regression analysis. and allows us to make predictions based on the data.

Pls help me I give points
Step-by-step explanation:
(f○g)(x) = f(g(x))
so, we use the expression of g(x) as the "x" in f(x).
(f○g)(x) = f(g(x)) = 3(x² + 3) - 1 = 3x² + 9 - 1 = 3x² + 8
so,
(f○g)(3) = 3×3² + 8 = 27 + 8 = 35
check :
g(3) = 3² + 3 = 9 + 3 = 12
f(g(3)) = f(12) = 3×12 - 1 = 36 - 1 = 35
correct.
In this problem, you must attempt to use the Ratio Test to decide whether the series converges.
The answer is (A) The Ratio Test says that the series converges absolutely.
What is the ratio test?
The Ratio Test is a test used to determine whether an infinite series converges or diverges. It involves taking the limit of the absolute value of the ratio of the (n+1)th term to the nth term as n approaches infinity. If the limit is less than 1, then the series converges absolutely.
We have:
[tex]|a_{n+1}/a_{n}| = |(e^(n+7)*sqrt(n+3)/((n+4)!)) / (e^(n+6)*sqrt(n+2)/((n+3)!))|[/tex]
[tex]|a_{n+1}/a_{n}| = e(sqrt(n+3)/sqrt(n+2)) * (n+3)/(n+4)[/tex]
We want to compute:
[tex]L = lim n- > infinity |a_{n+1}/a_{n}| = lim n- > infinity e(sqrt(n+3)/sqrt(n+2)) * (n+3)/(n+4)[/tex]
We can see that the exponent of e goes to 1 as n goes to infinity, and (n+3)/(n+4) goes to 1 as n goes to infinity. Therefore, L = 1.
Since L < 1, by the Ratio Test, the series converges absolutely.
Hence, the answer is (A) The Ratio Test says that the series converges absolutely.
