The rate of change from 2015 to 2017 is -$250

The amount he spend for lunch in 2015 = $800

The amount he spend for lunch in 2017 = $300

Therefore the total change = The amount he spend for lunch in 2017 - The amount he spend for lunch in 2015

Substitute the values in the equation

= 300 - 800

= -500

The total years from 2015 to 2017 = 2 years

The rate of change from 2015 to 2017 = The total change / The total years from 2015 to 2017

= -500 / 2

= -$250

Hence, the rate of change from 2015 to 2017 is -$250

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.

Again, analyzing the elements of A:

As x approaches negative infinity, (x-3)/(x-2) approaches 1. Therefore, the infimum of the set A is 1.

(c) The worst-case running time of deleting the minimum element from a (min) binary heap with N elements is O(logN).

In a binary heap, the minimum element is always located at the root, which is the topmost element of the heap. When the minimum element is deleted, it needs to be replaced with a new element from the heap in order to maintain the heap property.

The process of replacing the root element and restoring the heap property is known as "heapify" or "heap-down." In the worst case, the replacement element may need to be compared and swapped multiple times with its children until it reaches its correct position in the heap.

Since the height of a binary heap is logarithmic with respect to the number of elements (N), the worst-case number of comparisons and swaps required during the heap-down process is proportional to the height of the heap, which is O(logN).

Therefore, (c) the worst-case running time of deleting the minimum element from a binary heap is O(logN).

The equation can be written as y = 4x + 30,000, equation implies that an increase of $4 in marketing (x)

is associated with an increase of $32,000 in sales (γ). This can be seen by observing the coefficient of x, which is 4, and the constant term, which is 30,000. This means that for every $4 increase in marketing, there is an increase in sales of $4 multiplied by 8, which is equal to $32,000.

To put it in mathematical terms, the slope of the line is 4, which means that for every unit increase in x, y (sales) increases by 4 units. The y-intercept is 30,000, which means that when x (marketing) is equal to 0, y (sales) is equal to 30,000.

Therefore, the equation can be written as y = 4x + 30,000, which shows that an increase of $4 in marketing is associated with an increase of $32,000 in sales.

Answer:

5400 cycles

Step-by-step explanation:

You have the following function:

\(V(t)=220sin(180\pi t)\)

where t is in seconds.

In order to find the number of cycles in 1 minute, you first  calculate the frequency of the function, which is given by:

\(f=\frac{180\pi}{2\pi}=90s^{-1}\)

The number of cycles is then given by:

\(n=ft=(90s^{-1})(60s)=5400\ cycles\)

There are 5400 cycles in 1 minute

Answer:

0.46x3=1.38

Step-by-step explanation:

The probability that the child will catch 10 or more balls is approximately 0.4757 or 47.57%

In this scenario, we can model the number of successful catches by the child using a binomial distribution. Let's identify the values of N, P, and X, and calculate the probability.

N: N represents the number of trials or attempts. In this case, the ball is thrown 15 times, so N = 15.

P: P represents the probability of success in a single trial. Here, the chance of the child catching a ball is given as 0.4, so P = 0.4.

X: X represents the number of successful outcomes we are interested in. In this case, we want to find the probability that the child will catch 10 or more balls, so X = 10, 11, 12, 13, 14, 15.

To calculate the probability, we need to sum the probabilities of each individual outcome. We can use the binomial probability formula:

P(X=k) = (N choose k) * P^k * (1-P)^(N-k)

Let's calculate the probability using the formula for each value of X and sum the probabilities for X ≥ 10:

P(X ≥ 10) = P(X=10) + P(X=11) + P(X=12) + P(X=13) + P(X=14) + P(X=15)

P(X ≥ 10) = [ (15 choose 10) * (0.4^10) * (0.6^5) ] + [ (15 choose 11) * (0.4^11) * (0.6^4) ] + [ (15 choose 12) * (0.4^12) * (0.6^3) ] + [ (15 choose 13) * (0.4^13) * (0.6^2) ] + [ (15 choose 14) * (0.4^14) * (0.6^1) ] + [ (15 choose 15) * (0.4^15) * (0.6^0) ]

Now, we can calculate the probability:

P(X ≥ 10) ≈ 0.0032 + 0.0172 + 0.0524 + 0.1083 + 0.1651 + 0.1295

P(X ≥ 10) ≈ 0.4757

Therefore, the probability that the child will catch 10 or more balls is approximately 0.4757 or 47.57%

Given that \(\(T(n)\) = \(10n^2-3n\)\) if (\(\(n=1\)\)), you have to prove it by induction. So, we have proved it by induction that  \($$\(T(n)=10n^2-3n\)$$\)  if ( n= 1). The given statement is true for all positive integers n

Let's do it below: The base case (n=1) is given as follows: \(T(1)\) =\(10\cdot 1^2-3\cdot 1\\&\)=\(7\end{aligned}$$\). This implies that \(\(T(1)\)\) holds true for the base case.

Now, let's assume that \(\(T(k)=10k^2-3k\)\) holds true for some arbitrary \(\(k\geq 1\).\)

Thus, for n=k+1, T(k+1) = \(10(k+1)^2-3(k+1)\\&\) = \(10(k^2+2k+1)-3k-3\\&\)=\(10k^2+20k+7k+7\\&\) = \(10k^2-3k+20k+7k+7\\&\) = \(T(k)+23k+7\\&\) = \((10k^2-3k)+23k+7\\&\) =  \(10(k+1)^2-3(k+1)\).

Therefore, we have proved that the statement holds true for n=k+1 as well. Hence, we have proved it by induction that  \($$\(T(n)=10n^2-3n\)$$\)  if (n=1). Therefore, the given statement is true for all positive integers n.
