1) 2.7*10=27 (total number of miles ran by everyone)

4*3=12 (to find how many miles not averaged, multiply)

27-12=15 (how many miles left over for the other 6 people to run)

15/6= 2.5 (your answer)


2. 80/400= .2 (E)


3. Given:

x-5/4=-9/5

Mulitply everything by 4 to cancle it out

x-5=-36/5

add 5 to both sides

x=-11/5

A line has a slope of 0.5<br> and passes through the point (0,5). What is the equation of the line?
EleoNora [17]

Step-by-step explanation:

Hi there!

From the question;

The slope of the line is 5/10 or 0.5.

Also the equation of the line passes through the point (0,5).

Note: Use one point formula. {i.e (y-y1)=m(x-x1)}

So, use the formula here and keep the values;

(y-5) = 5/10(x-0)

or, 10(y-5) = 5x

or, 10y-50 = 5x

or, 5x - 10y +50 = 0

Therefore, the required equation is 5x - 10y +50 = 0 or x-2y+10 = 0.

Hope it helps!

use the accompanying statcrunch session to obtain a simple random sample of 5 high schools in the city of chicago. loading... cl
svetoff [14.1K]

Using sampling concepts, one sample of 5 high schools in the city of Chicago is given by:

Brooks,  Hyde Park, Young Womens, Marshall, Noble - UIC.

<h3>What is the missing information?</h3>

The problem is incomplete, but researching it on a search engine, it gives us a list of 15 high schools in Chicago, and asks us to take a sample of 5.

<h3>What is population and sample?</h3>

  • Population: Collection or set of individuals or objects or events whose properties will be studied.
  • Sample: The sample is a subset of the population, and a well chosen sample, that is, a representative sample will contain most of the information about the population parameter. A representative sample means that all groups of the population are inserted into the sample.

Hence, from the concepts of sample and populations, the sample of 5 means that we have to select 5 schools from the 15 listed, hence one possible option is given by:

Brooks,  Hyde Park, Young Womens, Marshall, Noble - UIC.
