Subtraction is a mathematical operation that reflects the removal of things from a collection. The ribbon that Millie already had is 7.1 feet.

<h3>What is subtraction?</h3>

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given Millie needs a total of 7.8 feet of ribbon for a school project. Also, She needs 0.7 more feet of ribbon. Therefore, the ribbon that Millie needs is,

Ribbon Millie had = Total Ribbon - ribbon that is needed

                              = 7.8 feet - 0.7feet

                              = 7.1 feet

Hence, the ribbon that Millie already had is 7.1 feet.

Ronch [10]

The standard error for the distribution of sampling proportions will be 0.0686.

<h3>What is standard error for the distribution of sampling proportions?</h3>

In mathematics, the difference between a data set and the populace's true average is known as primary data deviation from the mean.

According to the National Postsecondary Student Aid Study conducted by the U.S.

Department of Education in 2008, 62% of graduates from public universities had student loans.

We randomly select 50 students at a time.

Then the standard error for the distribution of sampling proportions will be

\rm Standard\  error = \sqrt{\dfrac{p(1-p)}{n}}\\\\Standard\  error = \sqrt{\dfrac{0.62(1-0.62)}{50}}\\\\Standard\  error = 0.0686

More about the standard error for the distribution link is given below.
