Step-by-step explanation:

Based on the information provided, the three true statements about Josiah's solution are:

"300 = x." - This statement is true because Josiah predicted that there were 300 rock songs on his MP3 player.

"He did not multiply the numerator and denominator by the correct number to equal 1,500." - This statement is true because in his proportion, Josiah multiplied the numerator and denominator by 30, which is not a multiple of 1,500.

"He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500." - This statement is true because to set up a proportion with 1,500 as the denominator, Josiah should have multiplied the numerator and denominator by a multiple of 1,500. In this case, 75 is a multiple of 1,500, so multiplying by 75 would have been the correct approach.

Step-by-step explanation:

We can conclude that the total cost of all meals was $205.

There were a total of 8 kids meals and 5 adult meals.

You'd have to divide 205 by 8, and you'd get 25.625.

Then, divide 205 by 5, and you'd get 41.

For example, we could say that each childrens meal was $15 ($120 total in kid's meals), and each adult was $17 ($85 total in adult meals).

When you total $85 and $120, it then given you a sum of $205.

There are many ways to complete this equation, but i feel that this is the easiest way.

Hope this helps! :)

a) By strong induction, any amount of postage worth 8 cents or more can be made from 3-cent or 5-cent stamps.

b) By strong induction, any amount of postage worth 24 cents or more can be made from 7-cent or 5-cent stamps.

c) By strong induction, any amount of postage worth 12 cents or more can be made from 3-cent or 7-cent stamps.

a. Prove that any amount of postage worth 8 cents or more can be made from 3-cent or 5-cent stamps.

Base case: For postage worth 8 cents, we can use two 4-cent stamps, which can be made using a combination of one 3-cent stamp and one 5-cent stamp.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 8, can be made from 3-cent or 5-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 8, we can use the induction hypothesis to make k cents using 3-cent or 5-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 3-cent stamp, we can replace it with a 5-cent stamp to get the same value. If the last stamp we added was a 5-cent stamp, we can replace it with two 3-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 3-cent or 5-cent stamps.

b. Prove that any amount of postage worth 24 cents or more can be made from 7-cent or 5-cent stamps.

Base case: For postage worth 24 cents, we can use three 8-cent stamps, which can be made using a combination of one 7-cent stamp and one 5-cent stamp.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 24, can be made from 7-cent or 5-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 24, we can use the induction hypothesis to make k cents using 7-cent or 5-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 5-cent stamp, we can replace it with two 7-cent stamps to get the same value. If the last stamp we added was a 7-cent stamp, we can replace it with three 5-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 7-cent or 5-cent stamps.

c. Prove that any amount of postage worth 12 cents or more can be made from 3-cent or 7-cent stamps.

Base case: For postage worth 12 cents, we can use one 3-cent stamp and three 3-cent stamps, which can be made using a combination of two 7-cent stamps.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 12, can be made from 3-cent or 7-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 12, we can use the induction hypothesis to make k cents using 3-cent or 7-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 3-cent stamp, we can replace it with two 7-cent stamps to get the same value. If the last stamp we added was a 7-cent stamp, we can replace it with one 3-cent stamp and two 7-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 3

Answer:

t = 3 hours

Step-by-step explanation:

The distance between A and B is 198 km

Kenan traveled by car from A to B at an average speed of 66km/h

We need to find the time taken to complete the journey. It can be solved as follows :

\(v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{198}{66}\\\\t=3\ h\)

So, the required time is equal to 3 hours.

To determine whether the series is absolutely convergent, conditionally convergent, or divergent, we need to evaluate the sum of the series. The given series is:

∞Σk=1 4k/(5k+k)

Simplifying the denominator, we get:

∞Σk=1 4k/(6k)

= ∞Σk=1 2/3

Since the summand is a constant value (2/3) and does not depend on k, the series is a divergent series.

Therefore, the given series is divergent.
Hi! To determine whether the series is absolutely convergent, conditionally convergent, or divergent, we will consider the given series:

Σ (4 / (5k)), where k = 1 to ∞

First, we'll examine absolute convergence by taking the absolute value of the series terms:

Σ |4 / (5k)| = Σ (4 / (5k))

Since the absolute value does not change the terms in this case, the series is the same. Now we'll apply the Ratio Test:

lim (n → ∞) |(4 / (5(k+1))) / (4 / (5k))|

= lim (n → ∞) (4 / (5(k+1))) * (5k / 4)

= lim (n → ∞) (5k / (5(k+1)))

= lim (n → ∞) (5k / (5k + 5))

= lim (n → ∞) (k / (k + 1))

= 1

The result of the Ratio Test is 1, which means the test is inconclusive. However, we can apply the Comparison Test with the harmonic series Σ (1 / k), which is known to be divergent. Since 4 / (5k) ≤ 1 / k for all k, and the harmonic series is divergent, the given series is also divergent by the Comparison Test.

So, the given series is divergent.

In this question, we are given that the number of seats per row increases at a constant rate on the main floor of the Kodak Hall at the Eastman Theater.

Steven counts 31 seats in row 3 and 37 seats in row 6. We need to determine how many seats are there in row 20. Let the number of seats in row 3 be a and the common difference be d.

Then, we can express the number of seats in row 6 and row 20 in terms of a and d.

The number of seats in row 6 is given to be 37. So, using the formula for the nth term of an arithmetic sequence, we can write an = a + (n - 1)d37 = a + 3d ...(1)Similarly, the number of seats in row 3 is given to be 31.

So, we have a3 = a + 2d31 = a + 2d ...(2)Subtracting equation (2) from equation (1), we get:37 - 31 = (a + 3d) - (a + 2d)6 = Thus, the common difference is 6.

Step-by-step explanation:

Answer

y = f(x) = 3x - 1

Explanation

The general form of the equation in point-slope form is

y - y₁ = m (x - x₁)

where

y = y-coordinate of a point on the line.

y₁ = This refers to the y-coordinate of a given point on the line

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

x₁ = x-coordinate of the given point on the line

Two lines that are parallel to each other have the same slope.

If the equation of a straight line is written in the form of y = 3x - 6,

,The slope and y-intercept form of the equation of a straight line is given as

y = mx + c

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

c = y-intercept of the line.

So, in y = 3x - 6, the slope = m = 3

So, using the point-slope form,

y - y₁ = m (x - x₁)

m = 3

(x₁, y₁) = (2, 5)

x₁ = 2, y₁ = 5

y - y₁ = m (x - x₁)

y - 5 = 3 (x - 2)

y - 5 = 3x - 6

y = 3x - 6 + 5

y = 3x - 1

In function notation, y = f(x)

So, the equation of the line required is

y = f(x) = 3x - 1

Answer:

would be A.

Step-by-step explanation:

A.

Given that n(B) = 275, n(A ∩ B ∩ C) = 60, n(A ∩ B ∩ CC) = 115, and n(AC ∩ B ∩ C) = 40. The value of n(AC ∩ B ∩ CC) = 5, which means the number of elements in AC ∩ B ∩ CC is 5

Let AC = X. Then we can write:

n(B) = 275

n(A ∩ B ∩ X) = 60

n(A ∩ B ∩ CC) = 115

n(X ∩ B ∩ C) = 40

n(X ∩ B ∩ CC) = ?

Now, let’s use a Venn diagram:

Using the given values and the Venn diagram, we can fill in some more values:

n(A) = 60 + n(A ∩ B ∩ C) + n(A ∩ B ∩ CC) + n(A ∩ BC) + n(A ∩ BCC) + n(AC ∩ B ∩ C) + n(AC ∩ B ∩ CC)

n(A) = 60 + 115 + n(A ∩ BC) + n(A ∩ BCC) + 40

n(A) = 215 + n(A ∩ BC) + n(A ∩ BCC)

Using a similar technique:

n(C) = 115 + n(B ∩ C ∩ CC) + n(A ∩ C ∩ CC) + n(A ∩ BC) + n(AC ∩ B ∩ C) + n(AC ∩ B ∩ CC)

n(C) = 115 + 20 + n(A ∩ BC) + n(AC ∩ B ∩ C) + n(AC ∩ B ∩ CC)

n(C) = 150 + n(A ∩ BC) + n(AC ∩ B ∩ CC)

Using the information we have, we can create two equations:

n(B) = 275n(A) = 215 + n(A ∩ BC) + n(A ∩ BCC)

n(C) = 150 + n(A ∩ BC) + n(AC ∩ B ∩ CC)

We can solve the third equation for n(AC ∩ B ∩ CC).

40 = n(X ∩ B ∩ C)

n(X ∩ B ∩ CC) = n(B) - n(X) + n(X ∩ B ∩ C)

n(X) = n(A ∩ B ∩ C) + n(A ∩ B ∩ CC) + n(AC ∩ B ∩ C) + n(AC ∩ B ∩ CC)

n(X) = 60 + 115 + 40 + n(AC ∩ B ∩ CC)

n(X) = 215 + n(AC ∩ B ∩ CC

)n(C) = 150 + n(A ∩ BC) + n(AC ∩ B ∩ CC)

275 = n(A) + n(B) + n(C) - n(A ∩ B ∩ C) - n(A ∩ B ∩ CC) - n(B ∩ C ∩ CC) - n(A ∩ BC) - n(A ∩ BCC) - n(AC ∩ B ∩ C) - n(AC ∩ B ∩ CC)

275 = 215 + n(A ∩ BC) + n(A ∩ BCC) + n(AC ∩ B ∩ C) + n(AC ∩ B ∩ CC) + n(B) + n(C) - 60 - 115 - 20

n(A ∩ BC) + n(A ∩ BCC) + n(AC ∩ B ∩ CC) = 20

Now,n(C) = 150 + n(A ∩ BC) + n(AC ∩ B ∩ CC)

150 + n(A ∩ BC) + n(AC ∩ B ∩ CC) = 115 + 20 + 40

n(A ∩ BC) + n(AC ∩ B ∩ CC) = 5

Therefore, n(AC ∩ B ∩ CC) = 5

Therefore, n(AC ∩ B ∩ CC) = 5, which means the number of elements in AC ∩ B ∩ CC is 5.
