The solution to the algebraic expression (2*3)*5 using a*b= a+b -2ab is; 68

Algebraic expressions are defined as the idea of expressing numbers using letters or alphabets without truly specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as a, b, c etc. These letters are usually referred to as variables.

We are given the format for the algebraic expression as;

a*b = a + b - 2ab

Thus, we can solve the expression (2*3)*5 as;

(2*3) = 2 + 3 - 2(2*3)

= -7

(-7 * 5) = -7 + 5 - 2(-7 * 5)

= -2 + 70

= 68

Answer:

523.3

Step-by-step explanation:

memorize this formula:

V = 4/3 π r³, where V = volume and r = radius.

so v=4/3π *5³ =125*4/3π =523.3

The volume of the solid formed by rotating the function f(x)=x about the x-axis from x=0 to x=1 is equal to the integral of the area of the cross-section of the solid from x=0 to x=1. The area of the cross-section is equal to the area of a circle with radius x, which is equal to πx. Thus, the volume of the solid is equal to the integral of πx from x=0 to x=1.

This integral can be solved using the formula for the area of a circle, which is equal to πr. Thus, the volume of the solid is equal to π∫x dx from x=0 to x=1. After solving the integral, the volume of the solid is equal to π/3. Thus, the volume of the solid formed by rotating the function f(x)=x about the x-axis from x=0 to x=1 is equal to 0.3333.

The strongly connected components of graph g are then determined to be the set of vertices {A, B, C, D, E}. This is because each vertex is reachable from every other vertex in the graph.

Graph g:

A→B

B→C

C→D

D→E

E→A

The strongly connected components algorithm is used to determine the strongly connected components of a directed graph. A strongly connected component is a subgraph of a directed graph in which every vertex is reachable from every other vertex.

The algorithm begins by running a depth-first search (DFS) on the graph. When running DFS on graph g, we start at vertex A and explore all its adjacent vertices before moving to the next vertex. In this case, we explore vertex B first. We then explore vertex C, followed by D and E. Finally, we explore vertex A again before finishing the DFS.

Once the DFS is complete, the algorithm then computes the transpose of the graph. The transpose of a graph is the graph with all the edges reversed. For graph g, this would be A←B, B←C, C←D, D←E, and E←A.

Finally, the algorithm runs a second DFS on the transpose of the graph. Since the edges are reversed, we start at vertex A and explore its adjacent vertices in reverse order. In this case, we explore vertex E first, followed by D, C, B, and finally A.

The strongly connected components of graph g are then determined to be the set of vertices {A, B, C, D, E}. This is because each vertex is reachable from every other vertex in the graph.

The correct order of the assumptions used in the derivation is: A, B, C, D, E. A states that the population is large, B: random, C: representative, D: large, and E states that the sampling is done without replacement.

The derivation of the Central Limit Theorem was based on five assumptions: (a) The population is large, (b) The sample is random, (c) The sample is representative, (d) The sample size is large, and (e) The sampling is done without replacement. The first assumption used in the derivation is that the population is large, which means that the number of individuals in the population is much greater than the sample size. This is important because the Central Limit Theorem states that the mean of the sample will approach the population mean as the sample size increases. The second assumption used is that the sample is random, which means that each individual in the population has an equal chance of being selected for the sample. This helps to ensure that the sample is representative of the population as a whole. The third assumption is that the sample is representative, which means that the characteristics of the sample are similar to those of the population. This is important because it allows us to make generalizations about the population based on the sample. The fourth assumption is that the sample size is large. This is important because the Central Limit Theorem states that the mean of the sample will approach the population mean as the sample size increases.

Step-by-step explanation:

The triangles ∆ABC and ∆BMK are similar triangles, and ∆ABC ≅ ∆BMK. The perimeter of the quadrilateral ACKB is equal to 74 feet.

Similar triangles are two triangles that have the same shape, but not necessarily the same size. This means that corresponding angles of the two triangles are equal, and corresponding sides are in proportion.

We have that line AC of the triangle ∆ABC is parallel to line BK of the triangle ∆BMK and also line CB of the triangle ∆ABC is parallel to line KM of the triangle ∆BMK which implies that lines AB and BM are of equal distance. Given that B is the midpoint of AM. We can conclude that triangles ∆ABC and ∆BMK are similar triangles.

Since ∆ABC is an equilateral triangle, then all the sides of the quadrilateral ACKB are equal and its perimeter is calculated as:

18.5 feet × 4 sides of the quadrilateral = 74 feet.

In conclusion, the triangles ∆ABC and ∆BMK are similar triangles, and ∆ABC ≅ ∆BMK. The perimeter of the quadrilateral ACKB is equal to 74 feet.

Answer:

width of the flag is 440 feet and the length is 780 feet

Step-by-step explanation:

Let's call the width of the flag "w". Then the length of the flag can be represented as "w + 340".

The perimeter of the flag is the sum of all four sides, so we can write the following equation:

2w + 2(w + 340) = 2,440

Expanding the second term on the left side and simplifying:

2w + 2w + 680 = 2,440

4w + 680 = 2,440

Subtracting 680 from both sides:

4w = 1,760

Dividing both sides by 4:

w = 440

So the width of the flag is 440 feet and the length is 780 feet (440 + 340).

Since the sum of the numbers selected must exceed 1, we know that n must be at least 1. Therefore, the expected value of X is finite and is equal to 2.

The expected value of the count of numbers that are selected can be found using the geometric distribution, since it models the number of trials until a success occurs.

Let X be the number of numbers that are selected until the sum of all numbers exceeds 1. Then X has a geometric distribution with parameter p, where p is the probability of success on each trial, i.e. the probability that the sum of all numbers selected does not exceed 1.

Since the numbers are selected uniformly over [0, 1], the probability of success on each trial is given by the area under the curve between 0 and 1 after the first number is selected.

On the first trial, the probability of success is 1. On the second trial, the probability of success is the area under the curve between 0 and (1 - the first number selected).

On the third trial, the probability of success is the area under the curve between 0 and (1 - the sum of the first two numbers selected), and so on.

The expected value of X can be found using the formula for the expected value of a geometric distribution:

E(X) = 1/p

Since the expected value of the sum of n independent and identically distributed uniform [0, 1] random variables is n/2, we can use this to find p:

E(X_1 + X_2 + ... + X_n) = n/2

where X_1, X_2, ..., X_n are the n numbers selected.

So, p = 1 / (1 + n/2).

Finally, we can substitute this into the formula for E(X) to find the expected value of X:

E(X) = 1 / (1 - n/2) = 2 / (2 - n)
