Answer:

I think it would be the addition property of equality

Step-by-step explanation:

Answer:

Fred = 31

Natalie = 15

Step-by-step explanation:

We have Natalie and Fred's whos age are unknown, we know that when added, their ages equal 46. While when multiplied with Natalie's age 4 times, their ages is 91.

Create two systems :

F = Fred

N = Natalie

F + N = 46

4N + F = 91

We can change the first equation to Natalie's age alone :

N = 46 - F

Now substitute this into the second equation :

4(46 - F) + F = 91

Distribute :

184 - 4F + F = 91

Subtract 184 from both sides :

-4F + F = -93

Add like terms :

-3F = -93

Divide -3 from both sides :

F = 31

Therefore, Fred is 31 years old. Now replace his age in the first equation :

31 + N = 46

46 - 31

15

Therefore, Natalie is 15 years old.

To design an efficient algorithm for partitioning the population of nano drones into groups A and B, maximizing the minimum distance between drones assigned to different groups, we can utilize a graph-based approach. First, we represent the nano drones as nodes in a graph, where the edges represent the distance between drones.

We then perform a graph partitioning algorithm, such as spectral clustering or the Kernighan-Lin algorithm, to divide the drones into two groups, A and B, while optimizing the minimum distance between the groups.

Here is a step-by-step explanation of the algorithm:

Create a graph representation of the nano drones, where each drone is a node, and the edges represent the distance between drones. The distance can be calculated using the 3D coordinates of the drones.

Apply a graph partitioning algorithm to divide the drones into two groups, A and B. Spectral clustering and the Kernighan-Lin algorithm are popular choices for this task.

During the partitioning process, the algorithm aims to minimize the total edge weight (distance) between the two groups while ensuring an even distribution of drones in each group. This optimization results in maximizing the minimum distance between drones assigned to different groups.

Once the partitioning is complete, the algorithm outputs the assignments of each drone to either group A or group B.

By utilizing a graph-based approach and employing efficient graph partitioning algorithms, this method can effectively and optimally partition the nano drones into two groups, A and B, while maximizing the minimum distance between drones assigned to different groups.

Using Area and perimeter formulae of rectangle,

a) the rate of change of Area is 14 cm²/sec

b) the rate of change of perimeter is zero.

c) length of diagonal is 13 cm

We have given that

length (l) is decreasing at the rate of 2 cm/min

and the width (w) is increasing at the rate of

2cm/min,

⇒ dl/dt = −2 cm/min and dw/dt = 2cm/sse

Thus the perimeter (P) of a rectangle is,

P=2(l+w) ---(1)

differentiating above equation with respect to time (t) we get,

dp/dt = 2(dl/dt + dw/dt )

=> dp/dt = 2( -2 + 2 ) = 0

=> P = constant

Hence, there is no change in perimeter of rectangle.

(b)Now, it is given that length (l) is decreasing at the rate of 2 cm/min

and the width (w) is increasing at the rate of 2 cm/min,

Thus the area (A) of a rectangle is, A= l× w

=> dA/dt = l ×dw/dt + w×dl/dt (used differentaion

we have l = 12 cm and w = 5 cm

=> dA/dt = 12 (2) + 5(-2)

=> dA/dt = 24 - 10 = 14

Hence, the area is increasing at the rate of

14 cm²/min.

c) length of diagonal = √(12)² + (5)² = √144+25

=> length of diagonal = √169 = 13 cm

Solving for Cartesian product n(B), we have n(B) = 72 / 24 = 3.

The Cartesian product is a mathematical operation that takes two sets and produces a set of all possible ordered pairs of elements from both sets.

In other words, if A and B are two sets, their Cartesian product (written as A × B) is the set of all possible ordered pairs (a, b) where a is an element of A and b is an element of B.

For example, if A = {1, 2} and B = {3, 4}, then A × B = {(1, 3), (1, 4), (2, 3), (2, 4)}.

By the question.

We know that n (Ax B) represents the number of elements in the set obtained by taking the Cartesian product of sets A and B.

Using the formula for the size of the Cartesian product, we have:

n (Ax B) = n(A) x n(B)

  12% loss

Step-by-step explanation:

The selling price is the sum of the cost price and the markup. Here, the markup (profit) is expressed as a percentage of the cost price.

The relation between selling price and cost price is ...

  selling price = cost price + cost price × markup fraction

  selling price = cost price × (1 + markup fraction)

Then the original cost price is ...

  cost price = (selling price) / (1 + markup fraction)

  cost price = #1.35 / (1 +8%) = #1.25

After the change in selling price, we can find the markup fraction (profit rate) to be ...

  1 + markup fraction = (selling price)/(cost price)

  markup fraction = (selling price)/(cost price) -1

  markup fraction = #1.10/1.25 -1 = 0.88 -1 = -0.12

The trader has a 12% loss when selling the oranges at #1.10.

The z-score for a 34-minute wait time in the cpt-memorial distribution is 1.1.

The z-score is a measure of how many standard deviations away from the mean a particular value falls. It is calculated by subtracting the mean from the value of interest and then dividing by the standard deviation.
In this case, we want to find the z-score for a 34 minute wait when the mean is 23 minutes and the standard deviation is 10 minutes.
z = (34 - 23) / 10
z = 1.1
So the z-score for a 34 minute wait is 1.1. This means that a 34 minute wait is 1.1 standard deviations above the mean wait time for cpt-memorial.
We can use this z-score to determine the percentage of wait times that fall below or above 34 minutes by using a standard normal distribution table. For example, a z-score of 1.1 indicates that approximately 86.42% of wait times are below 34 minutes, while 13.58% of wait times are above 34 minutes.
Overall, the z-score is a useful tool for understanding how a particular value relates to the distribution of a dataset.

b) The interest rate is of 8.19%.

The amount of money earned, in compound interest, after t years, is given by:

\(A(t) = P\left(1 + \frac{r}{n}\right)^{nt}\)

In which:

Item a:

Then:

\(A(t) = P\left(1 + \frac{r}{n}\right)^{nt}\)

\(A(5) = 1500\left(1 + \frac{0.0275}{2}\right)^{2(5)}\)

\(A(5) = 1719.49\)

Pietro will have $1,719.49 in his account after 5 years.

Item b:

Then:

\(A(t) = P\left(1 + \frac{r}{n}\right)^{nt}\)

\(1.5(1500) = 1500\left(1 + \frac{r}{4}\right)^{20}\)

\(1.5 = (1 + \frac{r}{4}\right)^{20}\)
