Answer:

b. set of real numbers R Superscript m is completely determined by its effect on the columns of the n times n identity matrix.

Step-by-step explanation:

A linear transformation T can be defined as a set of real numbers Rn → Rm is completely determined by its effect on columns of the n × n identity matrix because:

1. The standard matrice's column for the purpose of linear transformation from row Rn to Rm can be termed as the images of columns of the given n x n identity matrix.  

2. The standard matrice's column is the basis vector in row Rn. As we know that we can express any vector as a linear combination of these and T is expressed as a linear transformation.

Hence, the true option is (b)

Answer:

D. The company's chocolate bars weigh 3.2 ounces on average.

Step-by-step explanation:

We are given that  a company claims that its chocolate bars weigh 3.2 ounces on average.

The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.

Thus Option D is correct.

D. The company's chocolate bars weigh 3.2 ounces on average.
