The probability that Betty is first in line or Mary is last in line is (n^2 - n - 1)/n(n-1), as a function of n.
We can approach this problem by considering the probability of the complementary event, i.e., the probability that neither Betty is first in line nor Mary is last in line, and then subtracting this probability from 1 to get the probability we want.
The total number of ways the n kids can line up is n!, since there are n choices for the first person in line, n-1 choices for the second person, and so on down to 1 choice for the last person.
The number of ways in which neither Betty is first in line nor Mary is last in line is (n-2)!, since there are (n-2) choices for the first person in line (excluding Betty and Mary), (n-3) choices for the second person, and so on down to 1 choice for the second-to-last person.
Therefore, the probability that neither Betty is first in line nor Mary is last in line is
[(n-2)! / n!] = 1/n(n-1)
The probability we want is
1 - 1/n(n-1) = (n^2 - n - 1)/n(n-1)

lottery: every day, jorge buys a lottery ticket. each ticket has a probability of 0.2 of winning a prize. after seven days, what is the probability that jorge has won at least one prize? round your answer to four decimal places.
The probability after seven days of buying a lottery that Jorge would have at least one prize is 0.9364, rounded to four decimal places.
The question suggests that the probability of winning a prize on a single lottery is 0.2. This means that the probability of not winning a prize on that ticket is 0.8. This is because the probability is a total sum of 1. Hence, probability of not winning the prize:
1 - 0.2 = 0.8.
If Jorge has bought the tickets consistently, the probability would be multiplied the specific times. Therefore, the probability of not winning a prize on that ticket after seven days is equal to (0.8)⁷. Now the probability of winning a prize after seven days would be:
1 - (0.8)⁷ = 0.9364.
Therefore, the probability that Jorge has won at least one prize after seven days of buying lottery tickets is 0.9364 rounded to four decimal places.

Triangle ABC is similar to triangle ADE.
AB= 8CM
BC= 6CM
BD= 4CM
Work out the length of DE.
In the above mentioned similar triangles the length of DE is 5.25 cm.
What is triangle?A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.
Since triangles ABC and ADE are similar, their corresponding sides are proportional. We can use this fact to set up a proportion:
AB / AD = BC / DE
Substituting the given values, we get:
8 / AD = 6 / DE
Multiplying both sides by DE, we get:
8DE / AD = 6
Dividing both sides by 8/AD, we get:
DE = (6/8)AD
We need to find AD to solve for DE. To do this, we can use the fact that BD is an altitude of triangle ABC and triangle ADE is similar to triangle ABC. Therefore, triangle ABD is also similar to triangle ABC, and we can set up another proportion:
BD / AB = AD / AC
Substituting the given values, we get:
4 / 8 = AD / (8 + 6)
Simplifying, we get:
1/2 = AD / 14
Multiplying both sides by 14, we get:
AD = 7
Substituting this value back into the first equation, we get:
DE = (6/8)AD = (6/8)7 = 21/4 = 5.25
Therefore, the length of DE is 5.25 cm.

what is unitary method ?A problem-solving technique known as the unitary method is determining the value of only one unit and utilising that value to determine the value of another quantity which is either a multiple or indeed a fraction of the unit. It is frequently employed in maths, particularly in numeracy and algebra. In the unitary technique, a ratio or percentage is used to solve a problem where two quantities are related to one another by a constant number, that is, the value of one unit. This approach can be used to solve issues involving rates, costs, ratios, and other comparable quantities.
given
Let's start by calculating the price per load of the 5-pound package.
Cost per load is calculated as Box Cost / Number of Loads ($3.50 / 20 = $0.175).
Let's now calculate the price per load for the 15-pound box:
Cost each load is box price / the number of loads, which is $10.00 / (3 x 20) = $10.00 / 60 = $0.1667 per load.
to calculate the amount you will save per load if you purchase the 15-pound package.
Expense per load of a 5-pound box minus savings per load - The price per 15-pound box load.
Savings per load are equal to $0.175 - $0.1667, or $0.0083. (rounded to the nearest cent)
Hence, if you purchase the 15-pound box rather than the 5-pound box, you will save roughly $0.0083 every load.

The error you include in is: You only multiplied the 10h times the 2 and forgot to multiply it through the quantity to the -h.
What are the errors?
1. Raul should have first removed the innermost grouping symbols, the parentheses, by distributing 7h: In the original problem, Raul added the terms inside the parentheses before multiplying them by 7h, which is incorrect. To simplify the expression correctly, Raul should have first distributed 7h to both terms inside the parentheses, and then combined like terms.

one group of 3 adults and 5 childern paid a total of $32.50 for admisson.another group of 4 adults and 4 children paid $34.00 for admisson. what is the cost of admisson for one child
The cost of admission for one child is $5.60.
To find the cost of cost of admisson for one child, we can set up a system of linear equations using the given information.
Let A represent the cost of admission for one adult and C represent the cost of admission for one child.
We can write two equations based on the information given:
3A + 5C = $32.50 (for the first group)---------(1)
4A + 4C = $34.00 (for the second group)---------(2)
We can solve these equations step-by-step to find the value of C:
Multiply equation (2) by -1 so that we can eliminate A when adding both equations:
-4A - 4C = -$34.00
Add equations (1) and the modified equation (2) to eliminate A:
(3A + 5C) + (-4A - 4C) = $32.50 + (-$34.00)
-A + C = -$1.50
Multiply the whole equation by -1 to get rid of the negative sign:
A - C = $1.50 ---------(3)
Add equation (2) to the equation we got in step 3 to eliminate C:
(4A + 4C) + (A - C) = $34.00 + $1.50
5A + 3C = $35.50
Divide the equation by 5 to find the value of A:
A = $7.10
Substitute the value of A back into the equation 3:
$7.10 - C = $1.50
Solve for C:
C = $7.10 - $1.50
C = $5.60

five of these six triple integrals are over the same region of space: the tetrahedron pictured below with vertices at (0, 0, 0), (0, 0, 1), (1, 0, 0) and (1, 1, 0). one of these triple integrals is over a different region. which one is different?
All five of the triple integrals are over the same region of space, they should produce the same result so the one that produces a different result must be over a different region.
a. The triple integral for F(x, y, z) over the region D with order of integration dy dz dx is x=0 to 1, y=0 to x and z=0 to 1-x-y.
b. The triple integral for F(x, y, z) over the region D with order of integration dx dy dz is z=0 to 1, y=0 to 1-z and x=y to 1-z.
c. The triple integral for F(x, y, z) over is 0 ≤ z ≤ 1 - x - y, 0 ≤ x ≤ y and 0 ≤ y ≤ 1.
To evaluate the function F(x, y, z) over the region D, we need to set up the appropriate triple integral. Since the order of integration is given, we can use that to determine the limits of integration.
(a) dy dz dx:
In this order of integration, we integrate with respect to y first, then z, then x.
The limits of integration for x are from 0 to 1.
For y, the limits of integration depend on the value of x. When x is between 0 and y, the limits of y are from 0 to 1. When x is between y and 1, the limits of y are from 0 to x.
For z, the limits of integration depend on the value of y and x. When x is between 0 and y, and y is between 0 and 1, the limits of z are from 0 to 1 - x - y. When x is between y and 1, and y is between 0 and x, the limits of z are from 0 to 1 - x - y.
Therefore, the triple integral for F(x, y, z) over the region D with order of integration dy dz dx is:
∫∫∫ F(x, y, z) dy dz dx
x=0 to 1
y=0 to x
z=0 to 1-x-y
(b) dx dy dz:
In this order of integration, we integrate with respect to x first, then y, then z.
The limits of integration for z are from 0 to 1.
For y, the limits of integration depend on the value of z. When z is between 0 and 1 - x - y, the limits of y are from 0 to 1 - x - z. When z is between 1 - x - y and 1 - x, the limits of y are from 0 to x + y - 1.
For x, the limits of integration depend on the value of y and z. When z is between 0 and 1 - x - y, and y is between 0 and 1 - x - z, the limits of x are from 0 to 1 - z. When z is between 1 - x - y and 1 - x, and y is between 0 and x + y - 1, the limits of x are from y to 1 - z.
Therefore, the triple integral for F(x, y, z) over the region D with order of integration dx dy dz is:
∫∫∫ F(x, y, z) dx dy dz
z=0 to 1
y=0 to 1-z
x=y to 1-z
(c) dz dx dy:
In this order of integration, we integrate with respect to z first, then x, then y.
The limits of integration for y are from 0 to 1.
For x, the limits of integration depend on the value of y. When y is between 0 and x, the limits of x are from 0 to y. When y is between x and 1, the limits of x are from 0 to 1 - y.
For z, the limits of integration depend on the value of x and y. When y is between 0 and x, and x is between 0 and 1, the limits of z are from 0 to 1 - x - y. When y is between x and 1, and x is between 0 and 1, the limits of z are from 0 to 1 - y.
Therefore, the triple integral for F(x, y, z) over the region D in the order of integration dz dx dy is:
∫∫∫ F(x, y, z) dz dx dy
where the limits of integration are:
0 ≤ z ≤ 1 - x - y
0 ≤ x ≤ y
0 ≤ y ≤ 1

write an equivalent equation to ab=ac using a−1 such that, when it is simplified, the resulting equation will simplify to b=c.
The equivalent equation to ab=ac is b = c.
How we get the equivalent equation?An equivalent equation to ab=ac using a−1 that simplifies to b=c is:
Simplifying the expression by canceling out a⁻¹a, we get:
b = c
Therefore, the correct option is b = c.
We can start with the equation ab = ac and multiply both sides by a−1, which is the inverse of a. This gives us:
a⁻¹(ab) = a⁻¹(ac)
Simplifying the left-hand side of the equation by using the associative property of multiplication, we get:
(a⁻¹a)b = (a⁻¹a)c
Since a⁻¹a is equal to 1, we can simplify the expression to:
1b = 1c

The cone of the volcano has a height of 418 meters and a diameter of 434 meters. Find the volume of the cone. Round your answer to the nearest hundred thousand. Use 3.14 for π.
First, we need to find the radius of the cone. The diameter is given as 434 meters, so the radius is half of that:
radius = 434/2 = 217 meters
Next, we can use the formula for the volume of a cone:
V = (1/3)πr^2h
where r is the radius and h is the height.
Plugging in the values we have:
V = (1/3)π(217)^2(418)
V ≈ 41,796,778.5
Rounding to the nearest hundred thousand, we get:
V ≈ 41,800,000
Therefore, the volume of the cone is approximately 41,800,000 cubic meters.

The time taken for the object to travel from M to Y is 4 seconds.
To solve this problem, we will first find the distance between points M and Y, and then use the given average speed to find the time taken for the object to travel from M to Y.
Step 1: Find the distance between points M and Y
Since M is the midpoint of X and Y, and X and Y are 120 meters apart, we can find the distance between M and Y by dividing the total distance by 2:
Distance (M to Y) = (Total distance)/2 = 120 meters / 2 = 60 meters
Step 2: Find the time taken for the object to travel from M to Y
We are given the average speed of the object traveling from M to Y as 15 meters per second. We can use the formula: Time = Distance / Speed.
Time (M to Y) = Distance (M to Y) / Average speed = 60 meters / 15 meters per second = 4 seconds.

A linear equation is an equation that represents a straight line on a graph. It is an algebraic equation in which each term is either a constant or the product of a constant and a single variable.
Both Kwasi and Lola wrote true equations.
Kwasi's equation, b+132=180, is true because in a triangle, the sum of the interior angles is always 180 degrees. The angle measures opposite to sides b and c are a and f, respectively, so b+a+f=180. Since a+f=48+132=180- b, we can substitute and get b+132=180, which is true.
Similarly, Lola's equation, 132+f=180, is also true because the sum of the angles in a triangle is always 180 degrees, and angle A has a measure of 48 degrees,
Therefore, angle B and angle C must have a total measure of 180 - 48 = 132 degrees.

Random sampling is a type of sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected. Data is then collected from as high a percentage of this random subset as possible. Simple random sampling selects a smaller group (sample) from a larger group of the total number of participants (population).
Samples are at the heart of survey research. It is often called the population microcosm, and the process of drawing a sample should maximize the similarity of the sample to the population under study.

In the given word problem, they all start to mow their lawns at the same time, Beth will finish first.
Let's assume that Beth's lawn has an area of x, so Andy's lawn has an area of 2x, and Carlos' lawn has an area of (1/3) × 2x = (2/3)x. Let's also assume that Beth's lawn mower can mow at a rate of 1 unit of area per hour, so Carlos' mower can mow at a rate of 1/2 = 0.5 units of area per hour, and Andy's mower can mow at a rate of 1/3 units of area per hour. We can calculate the time it will take each person to mow their lawn by using the formula:
Time = Area / Rate.
Beth's time = x / 1

Use triangle ABH for problems 8-9.
8. Use triangle ABH to prove the the identity: (sin A)² + (cos A)² = 1.
9. Use triangle ABH to explain why sin A=cos(90°-A)
Answer:
Step-by-step explanation:
where angle A is opposite to side BH, angle B is opposite to side AH, and angle H is opposite to side AB.
Problem 8:
Using the Pythagorean theorem, we have:
AB² = AH² + BH²
Dividing both sides by BH², we get:
AB²/BH² = AH²/BH² + 1
(sin A)² + (cos A)² = 1, since sin A = AH/BH and cos A = BH/AB.
Therefore, (sin A)² + (cos A)² = 1, which is the identity we wanted to prove.
Problem 9:
Using the definition of cosine, we have:
cos(90°-A) = BH/AB
Using the Pythagorean theorem, we have:
AB² = AH² + BH²
Dividing both sides by AB², we get:
AB²/AB² = AH²/AB² + BH²/AB²
1 = (sin A)² + (cos A)², since sin A = AH/AB and cos A = BH/AB.
Therefore, sin A = √(1 - (cos A)²).
Substituting cos A = BH/AB, we get:
sin A = √(1 - (BH/AB)²)
Multiplying the numerator and denominator by AB², we get:
sin A = √(AB²/AB² - BH²/AB²)
sin A = √(1 - (BH/AB)²), which is the desired result.
Therefore, sin A = cos(90°-A).

Not Reading 70 40 110
Total 90 100 190
Part A:
To find the percentage of students who like both watching television and reading, we look at the number of students who like watching TV and reading, which is 20, and divide it by the total number of students surveyed, which is 190. Then, we multiply the result by 100 to express it as a percentage:
(20/190) x 100 = 10.53%
Therefore, 10.53% of the total students surveyed like both watching television and reading.
Part B:
To find the probability that a student who does not like watching television also does not like reading, we look at the number of students who do not like watching TV and do not like reading, which is 40, and divide it by the total number of students who do not like watching TV, which is 40 + 20 = 60.
Therefore, the probability that a student who does not like watching television also does not like reading is:
40/60 = 2/3 or 0.67
This means that out of all the students who do not like watching TV, 67% of them also do not like reading.

a coin is tossed 8 times which of the following represents the probability of the coin landing on heads all 8 times
Answer:
Probability = 1/256
Step-by-step explanation:
We Know
A coin has two faces, so there are two possible outcomes for every toss (head or tail); the sample space for a coin tossed 8 times is [tex]2^{8}[/tex] = 256
Landing on heads all 8 times is just one of the possible outcomes: 1
So, the probability is 1/256

Determine the volume of the following cylinders with the given dimensions. To break the code, substitute your answers in for the correct letters. Make sure to follow the order of operations! Round your answers to the hundredth place. Use 3.14 for an approximation for pi.
Therefore, the value of Code is 3954.076 and volumes of cylinders are: A)1539.38 cubic meters B)2892.8 cubic feet C)2712.96 cubic inches D)111.304 cubic inches.
What is volume?Volume is the measure of the amount of space that a three-dimensional object occupies. It is often measured in cubic units such as cubic meters, cubic feet, or cubic centimeters. The volume of an object can be determined by multiplying its length, width, and height (or depth) together, or by using specific formulas for the shape of the object.
Here,
A) Volume of cylinder = πr²h
= 3.14 x (15/2)² x 7
= 1539.38 cubic meters
B) Volume of cylinder = πr²h
= 3.14 x 8² x 14.4
= 2892.8 cubic feet
C) Volume of cylinder = πr²h
= 3.14 x 6² x 24
= 2712.96 cubic inches
D) Volume of cylinder = πr²h
= 3.14 x 2² x 8.9
= 111.304 cubic inches
Code = (2892.8 + 2712.96) - (111.304 + 1539.38)
Code = 5604.76 - 1650.684
Code = 3954.076
