The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".

To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.

The postfix expression for the given infix expression is:

"7 5 + 3 2 * 6 7 * 2 * - 4 /"

To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.

Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.

We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.

To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.

The prefix expression for the given infix expression is:

"/ - + 7 5 * 3 * 2 ( * 6 7 ) 4"

The total amount to be repaid on a simple interest loan of $4,000 for 3 years at an interest rate of 11% p.a. is $5,320.

In order to calculate the total amount to be repaid on a simple interest loan of $4,000 for 3 years at an interest rate of 11% p.a., we need to use the formula for simple interest:

Total amount = Principal + Interest

The principal is $4,000 and the interest rate is 11% per year. Let's convert the rate to a decimal:11% = 0.11We also need to know the time period in years. In this case, it's 3 years.

Now, we can use the formula:

Interest = Principal x Rate x Time

I = 4000 x 0.11 x 3 = 1320

The interest on the loan is $1,320. Therefore, the total amount to be repaid is:

Total amount = Principal + Interest = $4,000 + $1,320 = $5,320

Therefore, the total amount to be repaid on a simple interest loan of $4,000 for 3 years at an interest rate of 11% p.a. is $5,320.

The formula for the mean of x, given x ∼ bin(n, p) where n is a positive integer and 0 < p < 1, has been proven as μ = n * p.

To prove the formula for the mean of x, given x ∼ bin(n, p) where n is a positive integer and 0 < p < 1, follow these steps:
Step 1: Define the binomial distribution. In this case, x ∼ bin(n, p) represents a random variable x following a binomial distribution with n trials and probability of success p.
Step 2: Recall the formula for the mean (μ) of a binomial distribution. The formula for the mean of a binomial distribution is given:
μ = n * p
Step 3: Prove the formula. To prove this formula, consider the expected value of a single Bernoulli trial. A Bernoulli trial is a single experiment with two possible outcomes: success (with probability p) or failure (with probability 1-p). The expected value of a single Bernoulli trial is:
E(x) = 1 * p + 0 * (1 - p) = p
Step 4: Apply the linearity of expectation. The mean of the binomial distribution is the sum of the means of each individual Bernoulli trial. Since there are n trials, the mean of the binomial distribution (x) is:
μ = n * E(x) = n * p
So, the formula for the mean of x, given x ∼ bin(n, p) where n is a positive integer and 0 < p < 1, has been proven as μ = n * p.

The formula for the mean of x, or the expected value of x, is:
E(x) = np
To prove this formula, we need to use the definition of the expected value and the probability mass function of the binomial distribution.
First, let's recall the definition of expected value:
E(x) = Σ[x * P(x)]
where Σ represents the sum over all possible values of x, and P(x) is the probability of x occurring.
For the binomial distribution, the probability mass function is:
P(x) = (n choose x) * p^x * (1-p)⁽ⁿ⁻ˣ⁾
where (n choose x) is the binomial coefficient, which represents the number of ways to choose x items out of n without regard to order.
Now, let's substitute the binomial probability mass function into the formula for the expected value:
E(x) = Σ[x * (n choose x) * p^x * (1-p)⁽ⁿ⁻ˣ⁾]
Next, we need to simplify this expression. One way to do this is to use the identity:
x * (n choose x) = n * [(n-1) choose (x-1)]
This identity follows from the fact that we can choose x items out of n by either choosing one item and then selecting x-1 items out of the remaining n-1 items, or by directly choosing x items out of n.
Using this identity, we can rewrite the expected value as:
E(x) = Σ[n * (n-1 choose x-1) * p x * (1-p)⁽ⁿ⁻ˣ⁾]
Now, we can simplify further by noting that:
(n-1 choose x-1) = (n-1)! / [(x-1)! * (n-x)!]
and
n * (n-1)! = n!
Substituting these expressions into the expected value formula, we get:
E(x) = Σ[n! / (x-1)! * (n-x)! * px * (1-p) (n-x)]

We can simplify this expression by factoring out the common terms in the numerator:
E(x) = n * p * Σ[(n-1)! / ((x-1)! * (n-x)!) * p⁽ˣ⁻¹⁾ * (1-p)⁽ⁿ⁻ˣ⁾]
The sum inside the parentheses is just the binomial probability mass function for x-1, so we can rewrite it as:
Σ[(n-1)! / ((x-1)! * (n-x)!) * p⁽ˣ⁻¹⁾ * (1-p)⁽ⁿ⁻ˣ⁾] = P(x-1)
Substituting this back into the expected value formula, we get:
E(x) = n * p * Σ[P(x-1)]
Now, the sum over all possible values of x-1 is just the sum over all possible values of x, except that we're missing the last term (x=n). However, since the binomial distribution is discrete, the probability of x=n is just 1 minus the sum of all other probabilities. Therefore, we can add the missing term (n * P(n)) to the sum, giving:
Σ[P(x-1)] + P(n) = 1
Substituting this into the expected value formula, we get:
E(x) = n * p * (1 - P(n)) + n * P(n)
Simplifying this expression using the fact that P(n) = (n choose n) * p^n * (1-p)ⁿ⁻ⁿ = pⁿ, we get:
E(x) = n * p
This completes the proof of the formula for the mean of x.

The slοpe οf the line passing thrοugh the pοints (-2,-4) and (3,-4) is 0.

In mathematics, slοpe refers tο the measure οf the steepness οf a line. It is defined as the ratiο οf the vertical change (rise) between twο pοints.

Tο find the slοpe οf the line passing thrοugh the pοints (-2,-4) and (3,-4), we can use the slοpe fοrmula:

slοpe = (change in y) / (change in x)

Let's call the first pοint (-2,-4) "pοint 1" and the secοnd pοint (3,-4) "pοint 2". Then, we have:

change in y = y2 - y1 = (-4) - (-4) =

change in x = x2 - x1 = 3 - (-2) = 5

Substituting these values intο the slοpe fοrmula, we get:

slοpe = (change in y) / (change in x) = 0 / 5 = 0

First find the inverse of the function f(x) ....

\(f^{ - 1} (x)\)

For the inverse you swap the x abd y coordinates and make y the subject of the Equation again.

\(x = 4y - 3 \\ 4y = x + 3 \\ \frac{4y}{4} = \frac{x}{4} + \frac{3}{4} \\ f^{ - 1}(x) = \frac{x}{4} + \frac{3}{4} \)

For

\( {f}^{ - 1} (5)\)

In the place of x in the equation

\(f ^{ - 1} (x) \)

Plug in 5 and simplify.

\(f ^{ - 1} (5) = \frac{5}{4} + \frac{3}{4} \\ f ^{ - 1} (5) = \frac{8}{4} \\ f ^{ - 1} (5) = 2\)

The ways are the \(C_{20} ^{90}\) which are we  there to select the applicants who will be hired with the help of combination.

According to the statement

we have to find that the number of ways are there to select the applicants who will be hired.

So, For this purpose, we know that the

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Here we use the combination.

And from the given information:

20 applicants from a pool of 90 applications will be hired.

And according to this the combination becomes:

\(C_{20} ^{90}\)

then solve it

\(C_{20} ^{90} = \frac{90!}{20! (70!)}\)

\(C_{20} ^{90} = \frac{90*89*88*87*86*85*84*83*82!}{20*19*18*17*16*15*14!}\)

Then after solve it

\(C_{20} ^{90} = \frac{89*11*87*43*14*83*82!}{19*14!}\)

Now open another factorial

\(C_{20} ^{90} = \frac{89*11*87*43*14*83*82*81*80*79*78*77*76*75*74*73*72*71}{19*14*13*12*11*10*9*8*7*6*5*4*3*2*1}\)

Now solve this then

\(C_{20} ^{90} = {89*11*87*43*83*82*79*15*74*73*71}\).

So, The ways are the \(C_{20} ^{90}\) which are we  there to select the applicants who will be hired with the help of combination.

The supremum of the set A does not exist (it is negative infinity), and the infimum of the set A is 1.

To define the supremum and infimum of the set A, we first need to determine the properties of the set.

The set A is defined as A = {(x-3)/(x-2) ∈ R : x < 0}.

To find the supremum (also known as the least upper bound) of A, we need to find the smallest value that is greater than or equal to all the elements of A. In other words, we are looking for the least upper bound of the set A.

Let's analyze the elements of A:

For x < 0, the expression (x-3)/(x-2) can take on different values depending on the value of x. We need to find the maximum value that this expression can reach for all x < 0.

As x approaches 0 from the left side, (x-3)/(x-2) approaches negative infinity. Therefore, there is no finite supremum for the set A.

Next, let's find the infimum (also known as the greatest lower bound) of A. We need to find the largest value that is less than or equal to all the elements of A. In other words, we are looking for the greatest lower bound of the set A.

b. To find the probability a customer who ordered pancakes came to thediner late, we need to look at the intersection of the "pancakes" row and the "late" column. This gives us a probability of 0.1, or 10%

c. To determine whether breakfast choice and meal time are independent, we need to see if the probability of one event changes based on the occurrence of the other event. In this case, it seems that breakfast choice and meal time are not independent, as the probability of being late seems to differ based on what breakfast item the customer chose. For example, the probability of being late is higher for customers who ordered pancakes compared to those who ordered cereal. Therefore, the choice of breakfast item appears to be related to the probability of being late, and so breakfast choice and meal time are not independent.

The smallest positive integer n whose positive divisors have a product of n^6 is 2^6.

To find the smallest positive integer n satisfying the given condition, we need to consider the prime factorization of n. Since the product of positive divisors is equal to n^6, each prime factor of n must appear with an exponent that is a multiple of 6.

The smallest prime number is 2. If we raise 2 to the power of 6, we get 64, which satisfies the condition. Moreover, there is no smaller prime number that meets the requirement because any smaller prime raised to the power of 6 would result in a larger product.

Therefore, the smallest positive integer n whose positive divisors have a product of n^6 is 2^6, which is equal to 64.

A small number of individuals could cause a widespread distribution of the disease.

A researcher applying Watts's mathematical models to study the transmission of an airborne contagious disease can most reasonably assume that:

1. The disease transmission follows a network-based spread pattern.

In Watts's mathematical models, the focus is on network structures and the dynamics of spreading phenomena. Therefore, the researcher can reasonably assume that the transmission of the airborne contagious disease is influenced by the connections and interactions within a network. This implies that individuals are not randomly interacting but are part of a network where the disease can propagate along the links.

The spread of the disease is influenced by the characteristics of the network.

Watts's models highlight the importance of the network structure in determining the spread of contagion. Therefore, the researcher can reasonably assume that factors such as network connectivity, node centrality, clustering, and other network properties significantly influence the transmission dynamics of the airborne contagious disease. These characteristics can affect the speed, reach, and severity of the disease's spread within the network.
