The intervals are nested, each subsequent interval is contained within the previous one. Mathematically, this means I₁ ⊇ I₂ ⊇ ... In ⊇ ... . Therefore, we have:

1. I₁ ⊇ I₂ implies [a₁; b₁] ⊇ [a₂; b₂], which means a₁ ≤ a₂ and b₁ ≥ b₂.
2. I₂ ⊇ I₃ implies [a₂; b₂] ⊇ [a₃; b₃], which means a₂ ≤ a₃ and b₂ ≥ b₃.

To show that a1 ≤ a2 ≤ ... ≤ an ≤ ..., we need to use the fact that the sequence of intervals is nested, meaning that each interval is contained within the next one.

First, we know that I1 contains I2, so every point in I2 is also in I1. That means that a1 ≤ a2 and b1 ≥ b2.

Now consider I2 and I3. Again, every point in I3 is also in I2, so a2 ≤ a3 and b2 ≥ b3.

We can continue this process for all the intervals in the sequence, until we reach In. So we have:

a1 ≤ a2 ≤ ... ≤ an-1 ≤ an

and

b1 ≥ b2 ≥ ... ≥ bn-1 ≥ bn

This shows that the endpoints of the intervals are ordered in the same way.

Given that I₁ ⊇ I₂ ⊇ ... In ⊇ ... is a nested sequence of intervals and In = [an; bn], we can show that a₁ ≤ a₂ ≤ ... ≤ an ≤ ... and b₁ ≥ b₂ ≥ ... ≥ bn ≥ ... as follows:

Since the intervals are nested, each subsequent interval is contained within the previous one. Mathematically, this means I₁ ⊇ I₂ ⊇ ... In ⊇ ... . Therefore, we have:

1. I₁ ⊇ I₂ implies [a₁; b₁] ⊇ [a₂; b₂], which means a₁ ≤ a₂ and b₁ ≥ b₂.
2. I₂ ⊇ I₃ implies [a₂; b₂] ⊇ [a₃; b₃], which means a₂ ≤ a₃ and b₂ ≥ b₃.

Continuing this pattern for all intervals in the sequence, we can conclude that a₁ ≤ a₂ ≤ ... ≤ an ≤ ... and b₁ ≥ b₂ ≥ ... ≥ bn ≥ ... .

The output of the following code snippet will be 1, 2, 3, and 4.

The reason is that the while loop runs infinitely until the break statement is executed. The break statement terminates the loop if the value of x is divisible by 5. However, the value of x is incremented at each iteration of the loop before checking the condition. Here is the step-by-step explanation of how this code works:

Step 1: Assign 1 to x.x = 1

Step 2: Start an infinite loop using the while True statement.

Step 3: Check if the value of x is divisible by 5 using the if x % 5 == 0 statement.

Step 4: If the value of x is divisible by 5, terminate the loop using the break statement.

Step 5: Print the value of x to the console using the print(x) statement.

Step 6: Increment the value of x by 1 using the x += 1 statement.

Step 7: Repeat steps 3-6 until the break statement is executed.

The equation to predict how many hours, x, the second part of the trip will take is :x = (total distance - distance traveled in the first part) / average speed x = (125 - 75) / 50  x = 1

To predict how many hours, x, the second part of the trip will take, we can use the equation:

x = (total distance - distance traveled in the first part) / average speed

In this case, the total distance of the trip is 125 miles, and the distance traveled in the first part is the product of the average speed and the time taken for the first part, which is 50 miles/hour * 1.5 hours = 75 miles.

Substituting these values into the equation, we have:

x = (125 - 75) / 50

Simplifying the equation, we get:

x = 50 / 50

x = 1

Therefore, the equation to predict how many hours, x, the second part of the trip will take is:

x = (total distance - distance traveled in the first part) / average speed

x = (125 - 75) / 50

x = 1

This means that the second part of the trip will take 1 hour to complete after the bus stops to refuel.

Step-by-step explanation:

The charity needs to consider a range of prices that will guarantee it a monthly profit of at least $3000. To determine the range of prices that can generate such profit, we need to make use of the total cost function and the revenue function.

These functions can help us identify the price range that will provide a profit margin of $3000 or more.Let’s consider the total cost function first:Total Cost (TC) = Fixed Cost (FC) + Variable Cost (VC)In this problem, the fixed cost is given as $8000. Variable cost is calculated as VC = $20x (where x is the number of units of books sold).So, TC = $8000 + $20xFor the revenue function, the price per book is given as $30. We also know that the number of books sold is equal to the number of books printed and that the book printer requires a minimum order of 1000 books before they can start printing.

Therefore, the revenue function is given as R = $30x, where x is the number of units of books sold.Using these two functions, we can now calculate the profit function:Profit = Revenue - Total CostP = R - TCP = $30x - ($8000 + $20x)P = $10x - $8000We want to determine the range of prices that will generate a monthly profit of at least $3000. Therefore, we can set up an inequality and solve for x as follows:$10x - $8000 ≥ $3000$10x ≥ $11000x ≥ 1100Hence, x should be greater than or equal to 1100 to generate a profit of $3000 or more. Since the book printer requires a minimum order of 1000 books, the charity should set its price such that it will sell more than 1000 books to achieve the profit target.

Step-by-step explanation:

In this question, you are given a table with x and y points.

If you convert those values into coordinate points (x, y) you'll get the following points:

(4, 3) (2, 6) (5, 0)

A coordinate point is (x, y) meaning you should find the first value on the x-axis (horizontal axis) and move up y units.

Or, you can also find the y value on the y-axis (vertical axis) and move left x units.

For example, for (4, 3) you should find 4 on the x-axis, and move up 3 units.

For (2, 6) you should find 2 on the x-axis, and move up 6 units.

For (5, 0) you should find 5 on the x-axis, and move up 0 units.

b. The Z-score associated with the running time of runner for team 1 is -6.2.

c. The Z-score associated with the running time of runner for team 2 is -1.43.

a. Team 2's runner is faster as their time of 56.1 seconds is less than that of Team 1's runner who can run a race in 58 seconds.

b. Z-score associated with the running time of runner for team 1 will be calculated as follows:

Z-score = (X - µ) / σ

where X = runner's time = 58 seconds, µ = mean of the team = 64.2 seconds, σ = standard deviation of the team = 1 second

So, Z-score = (58 - 64.2) / 1= -6.2

Therefore, the Z-score associated with the running time of runner for team 1 is -6.2.

c. Z-score associated with the running time of runner for team 2 will be calculated as follows:

Z-score = (X - µ) / σ

where X = runner's time = 56.1 seconds, µ = mean of the team = 62.1 seconds, σ = standard deviation of the team = 4.2 seconds

So, Z-score = (56.1 - 62.1) / 4.2= -1.43

The relative frequency for B grade is 0.37.

The relative frequency, also called empirical probability or experimental probability refers to the ratio of the number of desired outcomes of an event occurring to the total number of trials in an actual experiment. In other words, a relative frequency reveals how often a specific type of event takes place within the total number of observations.

It is determined as a quotient value of frequency over the total possible outcomes. The sum of all relative frequencies for a particular experiment is always one. Hence, based on the given relative frequency distribution,

0.22 + x + 0.18 + 0.17 + 0.06 = 1

0.63 + x = 1

x = 1 – 0.63

x = 0.37

The relative frequency for B grade is 0.37.

Note: The question is incomplete. The complete question probably is: The following is a partial relative frequency distribution of grades in an introductory statistics course. Grade = A, B, C, D, F. Relative Frequency = 0.22, x, 0.18, 0.17, 0.06. Find the value of x, the relative frequency for B grade.

Answer:

To find the number of three-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6, with repetition allowed, we can use the formula for permutations:

Step-by-step explanation:

Number of permutations = (number of choices for the first digit) x (number of choices for the second digit) x (number of choices for the third digit)

In this case, we have 6 choices for each digit, since we are allowed to repeat the digits. Using the formula, we get:

Number of permutations = 6 x 6 x 6 = 216

Therefore, there are a total of 216 three-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6, with repetition allowed.

However, not all of these will be even. For a number to be even, the last digit must be even, so the last digit can only be 2, 4, or 6. This means that there are 3 choices for the last digit.

Therefore, the total number of even 3-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 is 366=108.

A. To save for her payout annuity with an ordinary annuity set up thirty years before her retirement, Holly Krech must make a monthly payment of $175.97.

B. If she sets up the ordinary annuity twenty years before her retirement, Holly Krech must make a monthly payment of $432.00.

To calculate the monthly payment for an ordinary annuity set up thirty years before retirement, we can use the formula for the present value of an ordinary annuity. Given the deposit amount of $218,437.048 and the total amount received from the annuity of $432,000, and solving for the monthly payment, we find that Holly must make a monthly payment of $175.97.

For an ordinary annuity set up twenty years before retirement, we use the same formula for present value. With the deposit amount and total amount received unchanged, we solve for the monthly payment, which comes out to be $432.00.

It's important to note that the monthly payment increases when the annuity is set up closer to the retirement date. This is due to the shorter time period available for saving, resulting in a higher required contribution to reach the desired payout amount.

Answer: 120 seconds

Step-by-step explanation: In order to find the maximum value of a function, you can take the derivative of the function and equalize the result to 0.

f'(x)=(-3x^2 + 12x)'=-6x+12=0

x=2

When x is 2, the function will reach its maximum value.

f(2)=-3(2)^2 + 12.2 = -12 + 24 = 12

The maximum value (f(x)) is equal to 12 and the time passed is 2 minutes which is equal to 120 seconds.

We then multiply 4 by 2 (the ratio) to get x = 8 as length JK.

Answer:

Step-by-step explanation:

From the figure, <LJK =~ <LPM , also, <JLK =~ <PLM because vertical angles are congruent.

By Angle - Angle (AA) Similarity postulate, of two angles of a triangle are congruent to two angles of another triangle , then the triangles are similar.

Hence, ∆JLK ~ ∆PLM

Use the corresponding side lengths to write a proportion.

\( \frac{jl}{pl} = \frac{jk}{pm} \)

\( \frac{4}{6} = \frac{x}{12} \)

Apply cross product property

\(6 \times x = 12 \times 4\)

\(6x = 48\)

Divide both sides of the equation by 6

\( \frac{6x}{6} = \frac{48}{6} \)

Calculate
