a) We cannot determine the probability

b) The mean of x - 55 is $28 - $55 = -$27, and the standard deviation of x - 55 is $0.45.

c) By the central limit theorem, the sampling distribution of x^-x will be approximately normal if the sample size is large enough.

d)  The probability that the average fee paid by the sample of households exceeds $55 is very close to 0.

a. We cannot determine the probability that the amount a randomly selected household pays for access to the internet exceeds $55 because we don't have information about the distribution of individual payments, only the mean and standard deviation of the population.

b. The mean of the sampling distribution of x is equal to the population mean, which is $28. The standard deviation of the sampling distribution of x is equal to the population standard deviation divided by the square root of the sample size, which is $10/sqrt(500) ≈ $0.45. Therefore, the mean of x - 55 is $28 - $55 = -$27, and the standard deviation of x - 55 is $0.45.

c. By the central limit theorem, the sampling distribution of x^-x will be approximately normal if the sample size is large enough. In this case, since the sample size is 500 and greater than 30, we can assume that the sampling distribution is approximately normal.

d. To find the probability that the average fee paid by the sample of households exceeds $55, we need to standardize the value of x using the sampling distribution of x^-x and then find the probability of a z-score greater than or equal to:

z = (55 - 28)/0.45 ≈ 60. The probability of a z-score greater than or equal to 60 is extremely small, as the normal distribution tails off quickly. Therefore, the probability that the average fee paid by the sample of households exceeds $55 is very close to 0.

The number of units manufactured at the cost of $8200 will be 95.

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the cost, C(x), for manufacturing x units of a certain product is

C(x) = x² - 9x + 30.

The number of units will be calculated as:-

C(x) = x² - 9x + 30

8200 = x² - 9x + 30

x² - 9x - 8170 = 0

Solve the equation as below,

x² - 9x - 8170 = 0

x² - 95x + 86x - 8170 = 0

x ( x - 95 ) + 86 ( x - 95 ) = 0

( x - 95 ) ( x + 86 ) = 0

x = 95 units

The average rate of change of the function, [tex]f(x) = 10\sqrt[3]{x}-5[/tex] over the interval of x=8 to x=64 is calculated as: 0.357.

The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.

A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.

The average rate of change = f(b) - f(a) / b - a.

Given the following:

The function is: [tex]f(x) = 10\sqrt[3]{x}-5[/tex]

Interval is: x = 8 to x = 64

Therefore:

a = 8

b = 64

f(a) = f(8) =

[tex]f(x) = 10\sqrt[3]{8}-5\\\\f(x)=10*(2)-5\\\\f(x)=20-5\\\\f(x)=15[/tex]

f(a) = f(8) = 15

f(b) = f(10)

[tex]f(x) = 10\sqrt[3]{64}-5\\\\f(x)=10*(4)-5\\\\f(x)=40-5\\\\f(x)=35[/tex]

f(b) = f(64) = 35

Therefore:

Step-by-step explanation:

According to the given information the answer is JK thus has a 10-unit length.

The measurement or size of a thing end to end is referred to as its length. In other words, it is the larger of an object's elevated two or three geometric dimensions. For instance, a rectangle's dimensions are determined by its length and width.

We must determine the separation among points J and K in order to get the length of JK. The distance formula is as follows:

d = √((x2 - x1)² + (y2 - y1)²)

Where (x1, y1) = (-5, 6) is the coordinate of J and (x2, y2) = (5, 6) is the coordinate of K.

Plugging in the values, we get:

d = √(5 - (-5))² + (6 - 6)²)

The final volume of a system with initially of 2 liters if the pressure is tripled and the temperature is tripled, is 11.57 liters.

The combined gas law equation relates the initial and final conditions of a system of gas by considering the effect of changes in pressure, volume, and temperature:

P1 * V1 / T1 = P2 * V2 / T2

Given the initial conditions of the system:

V1 = 2 liters

P1 = 1 atm

T1 = 273 K (room temperature)

And the changes in pressure and temperature:

P2 = 3 * P1 = 3 atm

T2 = 3 * T1 = 819 K

We can calculate the final volume of the system:

V2 = (P1 * V1 / T1) * (T2 / P2) = (1 atm * 2 liters / 273 K) * (819 K / 3 atm) = approximately 11.57 liters

So the final volume of the system would be approximately 11.57 liters if the pressure is tripled and the temperature is tripled from the initial conditions.

To solve this problem, we can use the formula for calculating the quarterly payment of a loan with compound interest:

Payment = (r * P) / (1 - (1 + r)^(-n))

where:

r = quarterly interest rate (12% / 4 = 0.03)

P = principal amount (remaining debt after down payment) = $150,000

n = total number of quarterly payments (10 years * 4 quarters per year = 40)

(1) Calculation of Quarterly Payment:

Payment = (0.03 * 150,000) / (1 - (1 + 0.03)^(-40)) = $2,365.87 (rounded to the nearest cent)

Therefore, the quarterly payment is $2,365.87.

(2) Calculation of Total Amount of Payment:

Total amount of payment = (number of payments) * (quarterly payment)

number of payments = 10 years * 4 quarters per year = 40

Total amount of payment = 40 * 2,365.87 = $94,634.80

Therefore, the total amount of payment is $94,634.80.

(3) Calculation of Total Amount of Interest Paid:

Total amount of interest paid = total amount of payment - principal amount

Total amount of interest paid = $94,634.80 - $150,000 = -$55,365.20

Note that the result is negative because the down payment ($50,000) exceeds the total amount of interest paid over the life of the loan. Therefore, in this case, the total amount of interest paid is $0, and the man ends up paying a total of $100,000 ($50,000 down payment + $50,000 in quarterly payments).

Answer:

To find the answer, we need to subtract the amount of bags Ben used from the amount he bought:

6 and 3/5 - 4 and 1/5

To subtract fractions, we need to have a common denominator. The smallest common denominator for 5 and 20 is 20, so we'll convert both fractions:

6 and 3/5 = 6 * 5/5 + 3/5 = 30/5 + 3/5 = 33/5

4 and 1/5 = 4 * 20/20 + 1/5 = 80/20 + 1/5 = 81/20

Now we can subtract:

33/5 - 81/20

We need to convert the mixed number to an improper fraction and find a common denominator:

33/5 - 81/20 = 132/20 - 81/20

Now we can subtract:

132/20 - 81/20 = 51/20

So Ben has 51/20 bags of rocks left. This can be simplified to 2 and 11/20 bags.

Conjectures are unsubstantiated claims. A theorem is created when someone proves a conjecture. In logic types that deal with conjunctions, the rule of simplification is a valid argument. The rule of inference that states that ∀xP(x) is true given the premise that P(c) is true for all elements c in the domain is known as universal generalization.

The Conjecture Rule

Conjectures are unsubstantiated claims. A theorem is created when someone proves a conjecture.

We seek to understand a conjecture on three levels: we want to know what it means, we want to know why we think the claim is true, and we want to know how it fits into a larger set of ideas.

Rule for Simplification

In logic types that deal with conjunctions, the rule of simplification is a valid argument.

This includes propositional and predicate logic, as well as natural deduction.

(1) Proof Rule: If we can reach a conclusion ϕ∧ψ, we can infer ϕ.

(2): If we can reach a conclusion ϕ∧ψ, we can infer ψ.

Rule of Universal Generalization

The rule of inference that states that ∀xP(x) is true given the premise that P(c) is true for all elements c in the domain is known as universal generalization. When we show that ∀xP(x) is true by taking an arbitrary element c from the domain and showing that P(c) is true, we are using universal generalization. The element c that we choose must be arbitrary and not a specific domain element.

" which simplifies to "12>x." The second part, (p ∨ q) ∧ r ∨ (p ∼ q) ∧ r ∨ (p ∧ q) ∧ r ∼ (p ∨ q), is always true when r is true, so it is equivalent to r. Thus, the entire statement is equivalent to "12>x and (x=7 or x>7)."

(a) p ∨ r: This statement is a logical disjunction, also known as an "or" statement. It is true if either the left side (p) is true or the right side (r) is true, or both. The statement "x>7" is equivalent to "x≥7 or x=7", so the statement p ∨ r can be read as "x≥7 or 12>x."

(b) r ∧ p: This statement is a logical conjunction, also known as an "and" statement. It is true only if both the left side (r) and the right side (p) are true. The statement "12>x" is equivalent to "x<12", so the statement r can be read as "x<12." Combining this with the statement p (x>7) gives "12>x>7."
