A researcher wishes to determine the average amount of money a student at UH spends on lunch. To accomplish this, he asks the fi
nadezda [96]

Answer:

<em>The population in this study is the entire students at UH </em>

<em></em>

Step-by-step explanation:

<em>A population is a set of events or items of interest for the experiment or research</em>. Since she wishes to determine the average amount of money a student of UH spend on lunch, then<em> the population the researcher wishes to make this decision from is the entire students at this school.</em>

<em>The first 100 students leaving the student center after 12:00 is a subset of the entire population, which means this first 100 students are the sample she wishes to draw from the entire population of students at UH</em>. This sample was probably chosen for some reason best known to the researcher and the nature of his/her research.

Chang and Carlotta solve this problem in two different ways. You have $50 in your bank account. You make $8 per hour mowing lawn
Daniel [21]

Answer:

8 hours

Step-by-step explanation:

You can solve this problem by inputting the values into an equation. Here is the equation below:

50 + 8x = 130

Lets solve for x. First you subtract 50 from 130.

1) 8x = 130 - 50

2) 8x = 80

Next, you divide 80 by 8 to get x by itself.

1) x = \frac{80}{8}

2) x = 10

This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.
