Find the binomial expression of

(x-5) (×-5)​

Answer:

-3 =m

Step-by-step explanation:

-27/m = 117/13

Solve for m

We can use cross products

-27 * 13 = 117 * m

Divide each side by 117

-27 * 13 /117 = 117*m/117

-351/117 = m

-3 =m

Answer:

m = 3

Step-by-step explanation:

\(\frac{27}{m} =\frac{117}{13}\)

To solve for m, first, use cross multiplication.

\(27*13=117*m\)

\(351=117m\)

And now, divide both sides by 117.

m = 3

The graduated cylinder is being checked for accuracy by comparing the measured volume to the actual volume using a buret. The student filled the cylinder to the mark of 25ml and then recorded the results of five trials.

To determine if the graduated cylinder is accurate.

The measured volume from the cylinder should be close to the actual volume measured by the buret.

If the measured volume consistently matches the actual volume within an acceptable range, then the graduated cylinder can be considered accurate.

However, if there is a significant discrepancy between the measured and actual volumes in multiple trials, then the graduated cylinder may not be accurate and may require calibration or replacement.

Step-by-step explanation:

The 95% confidence interval for the given population proportion is between 0.1716 to 0.2884.

The confidence interval for a population proportion is calculated by the formula,

\(C.I = \bar{p}\pm z_{\alpha/2}\sqrt{\frac{\bar{p}(1-\bar{p})}{n} }\)

Where \(\bar{p}\) is the sample proportion and α is the level of significance.

It is given that,

The statistics reported on CNBC projects, a surprising number of motor vehicles are not covered by insurance. The sample results are

The sample size n = 200;

The number of successes = 46

So, the sample proportion \(\bar{p}\) = 46/200 = 0.23

For a 95% confidence interval, the level of significance is

α = 1 - 95/100 = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

Then, the z-score for the value 0.025 is

\(z_{\alpha/2}\) = 1.96 (from the table)

Thus, the confidence interval is

\(C.I = \bar{p}\pm z_{\alpha/2}\sqrt{\frac{\bar{p}(1-\bar{p})}{n} }\)

⇒ C.I = 0.23 ± (1.96) × \(\sqrt{\frac{0.23(1-0.23)}{200} }\)

⇒ C.I = 0.23 ± 1.96 × 0.0298

⇒ C.I = 0.23 ± 0.0584

So, the upper limit is 0.23 + 0.0584 = 0.2884 and the lower limit is 0.23 - 0.0584 = 0.1716.

Therefore, the 95% confidence interval for the given population proportion lies between 0.1716 to 0.2884.

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).

Since both additivity and homogeneity conditions are met, we can conclude that T is a linear transformation.

To prove that T is a linear transformation, we need to demonstrate that it satisfies the following two conditions:

1. Additivity: T(A + B) = T(A) + T(B) for any matrices A and B in Mn,n.
2. Homogeneity: T(cA) = cT(A) for any matrix A in Mn,n and scalar c in R.

Let's start with additivity. Given two matrices A and B in Mn,n, their sum (A + B) has elements (a_ij + b_ij) in each position (i, j). Now let's find T(A + B):
T(A + B) = (a11 + b11) + (a22 + b22) + ... + (ann + bnn)

By splitting this sum into two separate sums, we have:
T(A + B) = (a11 + a22 + ... + ann) + (b11 + b22 + ... + bnn) = T(A) + T(B)

Therefore, the additivity condition is satisfied.

Now, let's consider the homogeneity condition. Given a matrix A in Mn,n and a scalar c in R, let's find T(cA). When we multiply A by c, each element becomes (c * a_ij):
T(cA) = c * a11 + c * a22 + ... + c * ann

By factoring out the scalar c, we have:
T(cA) = c(a11 + a22 + ... + ann) = cT(A)

Thus, the homogeneity condition is satisfied.

We do not have enough evidence to conclude that the true mean melting point differs from 95 at a significance level of 0.01.

To determine if the true mean melting point differs from 95, we can use a one-sample t-test with a significance level of 0.01.

The null hypothesis is that the true mean melting point is equal to 95, and the alternative hypothesis is that the true mean melting point is different from 95.

We can calculate the t-statistic using the formula:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

where sample size is 16, sample mean is 94.32, hypothesized mean is 95, and sample standard deviation is the same as the population standard deviation of 1.20.

Plugging in these values, we get:

\(t = (94.32 - 95) / (1.20 / \sqrt{(16)} ) = -2.6667\)

Using a t-distribution table with 15 degrees of freedom (n-1=16-1), and a two-tailed test at a significance level of 0.01, the critical t-value is ±2.947.

Since our calculated t-value of -2.6667 falls within the acceptance region (-2.947 < -2.6667 < 2.947), we fail to reject the null hypothesis.
