Answer and Step-by-step explanation:

Hello!

To calculate variance, we start by calculating the mean, or average of your question. Then, we subtract the mean from each data point, and square the differences. Next, we add up all the squared differences. Now, the last step is to divide The sum by n minus 1, where n equals the total number of data points from your question!

Hope this helps you!

Hugs,

Josh

<h3>Answer:  89,58 $ </h3>

Step-by-step explanation:

The formula :

\displaystyle \rm S=A\cdot \left (1+\frac{N}{100}  \right  )^{\big r}

where r is years ; N is the percentage by which we increase the price ; A is the original price

In our case :

\rm r=1 \ \ ;  \ \  A=100 \ \ ;   \  \  N=7,5\% \\\\ S=1000\cdot \bigg(  1+\dfrac{7,5}{100} \bigg)^1=1000\cdot 1,075=\boxed{1075\$}

Then the monthly salary is equal to:

\dfrac{1075}{12} \approx 89,58 \$

Please help! Giving Brainliest! 1.How many college students are majoring in elementary education?
anzhelika [568]
1. Unless you have the total students, it would be D, because we don't know how many total students there are, so we don't know how many students 100% would be.

2. E. There are only 7% of the students who major in a medical area. So say out of 100 students, 7% of that would be 7 people, and 19% would be 19 people, and so on. So therefore, the least people are majoring in a medical field.
