Maria's amount of land first exceeds Lucia's amount of land after 3 months.

To solve this problem, we need to find out when Maria's total amount of land first exceeds Lucia's total amount of land. Let's start by writing out the formulas for the amount of land each woman has after n months

Lucia's land after n months = 11 + 5n

Maria's land after n months = 6 × 1.4^n

Now we want to find the month, n, when Maria's amount of land first exceeds Lucia's amount of land. So we need to solve the following inequality

6 × 1.4^n > 11 + 5n

We can solve this inequality by using a trial-and-error approach or by using a graphing calculator. Here's one way to solve it using trial-and-error

Let's start by plugging in n = 1 and see if Maria's land is greater than Lucia's land:

6 × 1.4^1 = 8.4

11 + 5 × 1 = 16

Since 8.4 < 16, we know that Maria's land is not greater than Lucia's land after 1 month.

Now let's try n = 2

6 × 1.4^2 = 11.76

11 + 5 × 2 = 21

Since 11.76 < 21, we know that Maria's land is still not greater than Lucia's land after 2 months.

Let's keep trying larger values of n until we find the first month when Maria's land is greater than Lucia's land:

n = 3

6 × 1.4^3 = 16.384

11 + 5 × 3 = 26

Since 16.384 > 26, we know that Maria's land is greater than Lucia's land after 3 months.

The probability that a 65-year-old man will survive to reach the age of 70 is 88.4%, and also the probability man to survive till his 75th birthday is approx.59.952%.

The probability of a 65-year-old man reaching the age of 70 is the probability of surviving from age 65 to age 70, which is given as

p(70)/p(65) ⇒ 0.657/0.742 ≈ 0.88544 or 88.544%.

The probability of a man who just turned 70 dying within the next 5 years is 0.176.

Therefore, the probability of surviving for the next 5 years after turning 70 is

⇒ 1 - 0.176 ⇒ 0.824.

Thus, the probability of a man surviving till his 75th birthday is the probability of surviving from age 70 to age 75, which is given as

p(75)/p(70) ⇒ 0.657/0.903 × 0.824

Let m and n be two arbitrary integers. We want to prove that the relation R is an equivalence relation, i.e. it is reflexive, symmetric, and transitive.

Reflexive:  We must show that mRm for all m ∈ Z.

Since the difference of m and m is 0, which is an even number, we have mRm.

Therefore, the relation R is reflexive.

Symmetric: We must show that if mRn, then nRm.

Let mRn, i.e., the difference of m and n is an even number.

Then the difference of n and m is also an even number.

Therefore, nRm, and the relation R is symmetric.

Transitive: We must show that if mRn and nRp, then mRp.

Let mRn and nRp, i.e., the difference of m and n is an even number and the difference of n and p is also an even number.

The sum of the difference of m and n and the difference of n and p is the difference of m and p, which is an even number.

Therefore, mRp, and the relation R is transitive.


Since the relation R is reflexive, symmetric, and transitive, it is an equivalence relation.

The hourly cost of electricity in your home is $0.20

So, if we divide your $145.68 electric bill by the number of kilowatt-hours used in that month, we can determine the cost per kilowatt-hour.

If you used 500 kWh in the month of August, your cost per kWh would be $0.29136 ($145.68 / 500 kWh).

If you used 500 kWh in August, your average power usage would be approximately 0.69 kW (500 kWh / 720 hours).

To calculate the hourly cost of electricity, simply multiply the average power usage in kW by the cost per kWh.

Yes, the distribution of heights for all adults is approximately normal because normal distribution has a bell-shaped curve. The bell curve indicates that the majority of the data points are located around the mean, with fewer data points on either side. Furthermore, normal distribution has certain characteristics that are relevant to this question.

The average height of men is 69.2 inches, while the average height of women is 63.7 inches. Therefore, we can assume that the mean height for both genders would be approximately 66.45 inches, assuming the distribution is equal (i.e., half male, half female).

If we plot the data of both males and females together, the plot will likely resemble a bell curve as per the properties of normal distribution. Since most adults would fall within the average height range, the distribution of heights for all adults is considered approximately normal.

The probability of guessing randomly at least 8 correct answers in a 10 question multiple choice test where each question has 4 choices is 0.0385 or approximately 3.85%.

To find the probability of guessing at least 8 correct answers, we need to use the binomial probability formula:

P(X ≥ k) = 1 - P(X < k)

where

P(X ≥ k) is the probability of getting k or more correct answers

P(X < k) is the probability of getting less than k correct answers

n is the total number of questions in the test = 10

p is the probability of guessing the correct answer = 1/4

q is the probability of guessing the incorrect answer = 3/4

Now, we need to find the probability of getting less than 8 correct answers:

P(X < 8) = Σ P(X = k) for k = 0 to 7

P(X = k) = nCk * p^k * q^(n-k)

where nCk is the binomial coefficient for choosing k items from a set of n items.

P(X < 8) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 7)

P(X = k) = nCk * p^k * q^(n-k)

P(X = 0) = 10C0 * (0.25)⁰ * (0.75)¹⁰ ≈ 0.0563

P(X = 1) = 10C1 * (0.25)¹ * (0.75)⁹ ≈ 0.1875

P(X = 2) = 10C2 * (0.25)² * (0.75)⁸ ≈ 0.2813

P(X = 3) = 10C3 * (0.25)³ * (0.75)⁷ ≈ 0.2503

P(X = 4) = 10C4 * (0.25)⁴ * (0.75)⁶ ≈ 0.1450

P(X = 5) = 10C5 * (0.25)⁵ * (0.75)⁵ ≈ 0.0586

P(X = 6) = 10C6 * (0.25)⁶ * (0.75)⁴ ≈ 0.0161

P(X = 7) = 10C7 * (0.25)⁷ * (0.75)³ ≈ 0.0028

Therefore, P(X < 8) = 0.0563 + 0.1875 + 0.2813 + 0.2503 + 0.1450 + 0.0586 + 0.0161 + 0.0028 ≈ 1.0 - 0.0385 = 0.9615 or approximately 96.15%

To triple the area of a square, the new side lengths must be the length of the old sides multiplied by the square root of three (√3).

A square is a two-dimensional (2D) geometric shape that has four equal sides, and its angles are right angles, i.e., they measure 90°. The perimeter of a square is the sum of the length of all its sides, and its area is the product of its length and width. The diagonals of a square are equal in length and intersect at right angles.

To triple the area of a square, you need to increase the length of the square's sides by a certain factor. That factor is the square root of three, which is approximately 1.732. This implies that if the old side length of the square is "x," then the new side length of the square will be 1.732x.

This ratio of new side length to old side length of the square will triple the square's area (since (1.732x)² = 3x²). Therefore, to triple the area of a square, the new side lengths must be the length of the old sides multiplied by the square root of three (√3).

a. To approximate the change in alcohol level from 3 to 3.2 hours and the correct expression is OC: A'(3).

For this we need to calculate the difference between the values of A(t) at t = 3.2 and t = 3. The expression that correctly approximates this change is given by: A'(3) * 0.2, where A'(t) is the derivative of A(t) with respect to t. Therefore, the correct expression is OC: A'(3).

b. Similarly, to approximate the change in alcohol level from 4 to 4.2 hours, we need to calculate the difference between the values of A(t) at t = 4.2 and t = 4. The expression that correctly approximates this change is again given by: A'(4) * 0.2. Therefore, the correct expression is also OC: A'(4).

To calculate the approximate changes in alcohol level, we need to find the derivative of A(t) with respect to t:

A'(t) = 0.03746 + 0.20242t

a. The approximate change in alcohol level from 3 to 3.2 hours is:

A'(3) * 0.2 = (0.03746 + 0.20242(3)) * 0.2 ≈ 0.118

Therefore, the approximate change in alcohol level from 3 to 3.2 hours is 0.118.

b. The approximate change in alcohol level from 4 to 4.2 hours is:

A'(4) * 0.2 = (0.03746 + 0.20242(4)) * 0.2 ≈ 0.149
