Lara sold 3/5 of a box of candy, which is the same as 0.6 boxes of candy.

If Lucy sold 3/5 of a box of candy, then Lara sold 1/5 of 3/5, which is:

(1/5) * (3/5) = 3/25

Therefore, Lara sold 3/25 of a box of candy.

To find the number of boxes Lara sold, we can divide 3/25 by 1/5:

(3/25) ÷ (1/5) = (3/25) * (5/1) = 15/25 = 3/5

So Lara sold 3/5 of a box of candy, which is the same as 0.6 boxes of candy.

The woman bought 21 cards that play a song when they are opened, and 79 cards that do not play music.

Let's assume that the woman bought x cards that play a song when they are opened, and 100-x cards that do not play music.

We know the cost of the cards that play a song is 30 cents each, so the cost of x of these cards is 0.3x dollars.

Similarly, the cost of the cards that do not play music is 5 cents each, so the cost of 100-x of these cards is 0.05(100-x) dollars.

The total cost of all the cards is $10.25, so we can set up the following equation

0.3x + 0.05(100-x) = 10.25

Simplifying the equation, we get

0.3x + 5 - 0.05x = 10.25

0.25x = 5.25

x = 21

Therefore, the woman bought 21 cards that play a song when they are opened, and 100-21 = 79 cards that do not play music.

Yes, if there are more concordant pairs in the rank order, it makes sense that the Kendall correlation will be positive, as it suggests a tendency for the two variables to move in the same direction more often.

In Kendall correlation,

Rank values of each observation for the two variables are compared to determine the level of agreement or disagreement between them.

A concordant pair is when the rank order of the two variables is the same both increase or decrease together.

A discordant pair is when the rank order is different one variable increases while the other decreases.

If there are more concordant pairs, it means that the two variables tend to move in the same direction more often.

The correct equation to predict the number of years it would take for the painting to have a value of $10,000 is 15,000(0.85)[tex]^{(t)}[/tex] = 10,000. The correct answer is option (c).

The initial value of the painting is $15,000, and its value is predicted to decay by 15% each year. This means that its value after t years can be represented by the equation:

V(t) = 15,000(0.85)[tex]^{(t)}[/tex]

We want to find the number of years it would take for the value to reach $10,000, so we set V(t) equal to 10,000 and solve for t:

10,000 = 15,000(0.85)[tex]^{(t)}[/tex]

Dividing both sides by 15,000 gives:

0.6667 = 0.85[tex]^{(t)}[/tex]

Taking the natural logarithm of both sides gives:

ln(0.6667) = t ln(0.85)

Solving for t gives:

t = ln(0.6667) / ln(0.85) = 2.294

So it would take approximately 2.294 years for the painting to have a value of $10,000. The right option is (c).

The sum of all the terms in the arithmetic progression is 3507.

The common difference in an arithmetic progression is the difference between any two consecutive terms. Let the common difference be d. Then, the third term is 2 + d, the fourth term is 2 + 2d, and so on. Also, let the last term be n.

Since the last term is greater than 150, we can write n = 2 + (n-2)d > 150. Solving this inequality, we get d < 74. Therefore, the common difference can be 1, 2, 3, ..., 73.

Using the formula for the sum of an arithmetic progression, we get the sum of all the terms as (n/2)(first term + last term) = (n/2)(2 + n d) = (n/2)(11 + (n-1)d).

We can substitute n = (last term - first term)/d + 1 and solve for the sum. This gives us the final answer of 3507.

The dealer bought 42 radios.

Let x be the number of radios the dealer bought.

Let y be the price the dealer paid for each radio.

We know that the dealer bought x radios for a total of $1,008, so:

x * y = 1008

We also know that the dealer gave away 6 radios and sold the rest for $14 more than she paid for each radio, breaking even. This means that the total revenue from selling the remaining radios is equal to the total cost of buying them:

(x - 6) * (y + 14) = x * y

Simplifying this equation, we get:

xy + 14x - 6y - 84 = xy

14x - 6y = 84

7x - 3y = 42 (dividing by 2 on both sides)

Now we have two equations:

x * y = 1008

7x - 3y = 42

We can use substitution or elimination to solve for x and y. Let's use elimination by multiplying the second equation by y/3 and adding it to the first equation:

x * y + (7x - 3y) * (y/3) = 1008 + 42 * (y/3)

xy + 7xy/3 - y²/3 = 1008 + 14y

10xy/3 - y²/3 - 14y - 1008 = 0

Multiplying both sides by 3, we get:

10xy - y² - 42y - 3024 = 0

Now we can use the quadratic formula to solve for y:

y = (-b ± sqrt(b² - 4ac)) / 2a

where a = -1, b = -42, and c = -3024:

y = (-(-42) ± sqrt((-42)² - 4(-1)(-3024))) / 2(-1)

y = (42 ± sqrt(42² - 4*3024)) / 2

y = (42 ± 126) / 2

y = 84 or y = -42

Since the price of a radio cannot be negative, we can discard the second solution and conclude that y = 84.

Now we can solve for x using the first equation:

x * y = 1008

x * 84 = 1008

x = 12

Therefore, the dealer bought 12 radios.

Answer:

18:19

Step-by-step explanion:
To solve this problem, we need to first calculate the time it takes for the plane to fly from Singapore to Sydney:

Time = Distance ÷ Speed

Time = 6310 km ÷ 757.2 km/h

Time ≈ 8.34 hours

This is the time it takes to fly from Singapore to Sydney in Singapore time. However, we need to convert this time to Sydney time, which is 2 hours ahead of Singapore time. Therefore, the local time when the plane arrives in Sydney is:

Time in Sydney = Singapore time + 2 hours + Flight time

Time in Sydney = 07:45 + 2 hours + 8.34 hours

Time in Sydney = 18:19

Therefore, the local time when the plane arrives in Sydney is 18:19 using the 24-hour clock.

The four possible decodings of the ciphertext c = 823 845 737 are 156276219, 561472502, 1188260592, and 197895457.

To encode the plaintext m = 414 892 055, we first need to compute the corresponding ciphertext c using the Rabin cryptosystem.

The Rabin cryptosystem involves four steps: key generation, message encoding, message decoding, and key decryption. Since we already have the key n, we can skip the key generation step.

To encode the message m, we compute:

c ≡ m^2 (mod n)

Substituting the given values, we get:

c ≡ 414892055^2 (mod 1359692821)

c ≡ 1105307085 (mod 1359692821)

Therefore, the encoded ciphertext is c = 1105307085.

(b) To find the four decodings of the ciphertext c = 823 845 737, we need to use the Rabin cryptosystem to compute the four possible square roots of c modulo n.

First, we need to factorize n as n = 32359 · 42019. Then we compute the two square roots of c modulo each of the two prime factors, using the following formula:

x ≡ ± [tex]y^((p+1)/4) (mod p)[/tex]

where x is the square root of c modulo p, y is a solution to the congruence y^2 ≡ c (mod p), and p is one of the prime factors of n.

For the first prime factor p = 32359, we can use the following values:

y ≡ 3527^2 (mod 32359) ≡ 15467 (mod 32359)

x ≡ ± y^((p+1)/4) (mod p) ≡ ± 6692 (mod 32359)

Therefore, the two possible square roots of c modulo 32359 are 6692 and 25667.

For the second prime factor p = 42019, we can use the following values:

y ≡ 3527^2 (mod 42019) ≡ 25058 (mod 42019)

x ≡ ± y^((p+1)/4) (mod p) ≡ ± 1816 (mod 42019)

Therefore, the two possible square roots of c modulo 42019 are 1816 and 40203.

To find the four possible decodings of the ciphertext c = 823 845 737, we combine each of the two possible square roots modulo 32359 with each of the two possible square roots modulo 42019, using the Chinese Remainder Theorem:

x ≡ a (mod 32359)

x ≡ b (mod 42019)

where a and b are the two possible square roots modulo 32359 and 42019, respectively.

The four possible values of x are:

x ≡ 156276219 (mod 1359692821)

x ≡ 561472502 (mod 1359692821)

x ≡ 1188260592 (mod 1359692821)

x ≡ 197895457 (mod 1359692821)

Therefore, the four possible decodings of the ciphertext c = 823 845 737 are 156276219, 561472502, 1188260592, and 197895457.

[tex]sin(theta) = opposite/hypotenuse = 4/5[/tex]

[tex]cos(theta) = adjacent/hypotenuse = 3/5[/tex]

Since theta is a first-quadrant angle, we know that tan(theta) = sin(theta)/cos(theta).

Using the half-angle formula for tangent, we have:

[tex]tan(1/2 * theta) = ±√((1 - cos(theta))/2) / (1 + √((1 - cos(theta))/2))[/tex]

We can substitute the values of sin(theta) and cos(theta) that we found earlier:

[tex]tan(1/2 * theta) = ±√((1 - 3/5)/2) / (1 + √((1 - 3/5)/2))[/tex]

[tex]tan(1/2 * theta) = ±√(1/5) / (1 + √(1/5))[/tex]

[tex]tan(1/2 * theta) = ±√5 - 1[/tex]

Since theta is in the first quadrant, tan(1/2 * theta) is positive. Therefore:

[tex]tan(1/2 * theta) = √5 - 1[/tex]

We can simplify this expression by rationalizing the denominator:

[tex]tan(1/2 * theta) = (√5 - 1) / (√5 + 1) * (√5 - 1) / (√5 - 1)[/tex]

The amount that the first rank takes is 1934 dinars, and the amounts that the second and third ranks take are 967 dinars and 483.5 dinars (rounded to 484 dinars), respectively.

Let's assume that there are three brothers, including Musa. Let X be the amount of money that the brother with the highest average takes, and let Y be the amount of money that the brother with the third rank takes.

According to the given conditions, we can write the following equations:

Let's simplify equation 1:

X + Y = 2900

Also, we know that:

X = (2Y + X)/2

(The amount that the third rank takes is half of what the first rank takes)

Simplifying this equation:

2X = 2Y + X

X = 2Y

Substituting this value of X in equation X + Y = 2900:

3Y = 2900

Y = 2900/3

Y ≈ 966.67

As the amount given must be a whole number between two consecutive natural numbers, we can round Y to the nearest natural number:

Y = 967

Then, X = 2Y = 2*967 = 1934

Therefore, the amount that the first rank takes is 1934 dinars, and the amounts that the second and third ranks take are 967 dinars and 483.5 dinars (rounded to 484 dinars), respectively.
