Step-by-step explanation:

The result is 20.997 if 497 is Divided by 23.67 and tenth 2.099 and hundredth is 0.2099

A decimal is a number that has two parts one is whole number, and the remaining is fractional part. The two parts are separated by a point named decimal point.

Hundredth means the fraction that is equal to one is divided by 100

and tenth of a number means the number is divided by 10.

As example a hundredth of 4444 is 44.44 and tenth of 4444 is 444.4.

We are given two numbers 497 and 23.67

In the above, 497 is a whole number and 23.67 is a decimal number.

In order to divide these, we can multiply the two numbers by 100

and get 49700 and 2367

now 49700 is divided by 2367

and the result is 20.99

In the next, the tenth of 20.99 is 2.099 and hundredth of 20.99 is 0.2099

Let's solve ~

\(\qquad \sf  \dashrightarrow \: ( - 3 {p}^{3} + 5 {p}^{2} - 2 p) + ( - p {}^{3} - 8 {p}^{2} - 15p)\)

\(\qquad \sf  \dashrightarrow \: - 3 {p}^{3} + 5 {p}^{2} - 2 p - p {}^{3} - 8 {p}^{2} - 15p\)

\(\qquad \sf  \dashrightarrow \: - 3 {p}^{3} -p³+ 5 {p}^{2} - 8 {p}^{2} -2p - 15p\)

\(\qquad \sf  \dashrightarrow \: - 4{p}^{3} -3 {p}^{2} - 17p \)

Answer:

First we must distribute the 2.6 to everything inside the ()

The new equation would then be 14.3p-32.24 = 127.92

Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.

The new equation would then be 14.3p = 160.16

Then you divide each side of the = by 14.3, that way the p becomes isolated. 14.3p/14.3 = 160.16/14.3

Then you're left with p=11.2

Therefore, \(-3/4 + 1 1/8 = 11/8\) or\(1 3/8\) as a mixed number in simplest form.

A fraction is a way of representing a part of a whole or a quantity that is not a whole number. It is expressed in the form of a numerator and a denominator separated by a line, called a fraction bar or a vinculum. The numerator is the top number in a fraction, and the denominator is the bottom number. The numerator represents the number of equal parts of a whole, and the denominator represents the total number of equal parts into which the whole is divided. For example, the fraction 3/4 represents three equal parts of a whole that is divided into four equal parts. Fractions can be used in many mathematical operations, such as addition, subtraction, multiplication, and division, and are an essential concept in mathematics.

Find \(-3/4+1 1/8\). Express your answer as a fraction or mixed number in simplest form.

To add -3/4 and 1 1/8, we first need to convert the mixed number to an improper fraction:

\(1 1/8 = 8/8 + 1/8 = 1 + 1/8 = 8/8 + 8/8 + 1/8 = 16/8 + 1/8 = 17/8\)

Now we can add the two fractions:

\(-3/4 + 17/8\)

To add these fractions, we need to find a common denominator, which is the least common multiple of the denominators 4 and 8, which is 8. We can convert -3/4 to an equivalent fraction with denominator 8 by multiplying the numerator and denominator by 2:

\(-3/4 = -6/8\)

Now we can add the two fractions:

\(-6/8 + 17/8 = 11/8\)

Therefore,\(-3/4 + 1 1/8 = 11/8 or 1 3/8\) as a mixed number in simplest form.

Step-by-step explanation:

The probability that at least 15 buy their lunch is 0.957.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Here, we have

Given: P = 0.81

n = 22

We have to calculate the probability that at least 15 buy their lunch.

P(x≥15)

We use binomial distribution formula here and we get

P(X= x) = ⁿCₓpˣqⁿ⁻ˣ

P(X ≥15) = P(X= 15) + P(X= 16) + P(X= 17) + P(X= 18) + P(X= 19) + P(X= 20) + P(X= 21) + P(X= 22)

P(X ≥15) = ²²C₁₅(0.81)¹⁵(1-0.81)²²⁻¹⁵ + ²²C₁₆(0.81)¹⁶(1-0.81)²²⁻¹⁶ + ²²C₁₇(0.81)¹⁷(1-0.81)²²⁻¹⁷ + ²²C₁₈(0.81)¹⁸(1-0.81)²²⁻¹⁸ + ²²C₁₉(0.81)¹⁹(1-0.81)²²⁻¹⁹ + ²²C₂₀(0.81)²⁰(1-0.81)²²⁻²⁰ + ²²C₂₁(0.81)²¹(1-0.81)²²⁻²¹ + ²²C₂₂(0.81)²²(1-0.81)²²⁻²²

P(X ≥15) = 0.65 + 0.1205 + 0.181 + 0.216 + 0.192 + 0.123 + 0.050 + 0.0097

P(X ≥15) = 0.957

Hence, the probability that at least 15 buy their lunch is 0.957.

Answer:

y - 1 = (-2/3)(x + 9)

Step-by-step explanation:

Here you are given a point on a line and the slope of the line.  You'll need to apply the "point-slope" formula

y - k = m(x - h) (Memorize this)

Then m = slope = -2/3, h = -9 and k = 1.

Making the appropriate substitutions, we get:

y - 1 = (-2/3)(x + 9)

(1) Every vector space V with dimension n and a generating set S contains a subset that forms a basis for V.

(2) The generating set S for a vector space V must contain at least n vectors.

(1) To prove that there is a subset of S that forms a basis for V, we can use the concept of linear independence. Since S generates V, we can start with S as a potential basis for V. If S is linearly independent, then it already forms a basis for V.

Otherwise, we can remove vectors from S that are linearly dependent on the remaining vectors until we obtain a linearly independent subset. This subset will still generate V and will form a basis for V.

(2) To prove that S must contain at least n vectors, we use the fact that the dimension of a vector space is the minimum number of vectors required to generate it. Since V has dimension n, it implies that at least n vectors are needed to generate V.

Therefore, the generating set S for V must contain at least n vectors.

These proofs highlight the fundamental properties of vector spaces and their generating sets, emphasizing the existence of bases and the relationship between the dimension of the vector space and the number of vectors needed in its generating set.

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

Part A: An open circle on a number line represents an excluded value, indicating that the endpoint is not included in the solution set of the inequality. It is used when the inequality includes the symbols < (less than) or > (greater than), which denote strict inequality.

Part B: A closed circle on a number line represents an included value, indicating that the endpoint is part of the solution set of the inequality. It is used when the inequality includes the symbols ≤ (less than or equal to) or ≥ (greater than or equal to), which denote inclusive inequality.

Part C: The shading on the number line represents the range of values that satisfy the given inequality. It indicates which values make the inequality true. Typically, the shading is done to the right or left of the circle(s) depending on whether the inequality is greater than or less than.

Part A:

For example, if we have the inequality x > 2, we would represent it with an open circle at 2 on the number line. This means that 2 itself is not a valid solution, but any value greater than 2 is included.

Part B:

For example, if we have the inequality x ≥ -3, we would represent it with a closed circle at -3 on the number line. This means that -3 itself is a valid solution, as well as any value greater than or equal to -3.

Part C:

For example, if we have the inequality x > 2, we would shade the portion of the number line to the right of the open circle at 2. The shaded region represents all the values greater than 2 that satisfy the inequality. The shading visually illustrates the solution set and helps identify the range of valid values for the variable in the given inequality.
