A researcher wishes to determine the average amount of money a student at UH spends on lunch. To accomplish this, he asks the first 100 students leaving the Student Center after 12:00 noon how much they had just spent on lunch. Identify the population.

The population in this study is the entire students at UH

Step-by-step explanation:

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

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. This sample was probably chosen for some reason best known to the researcher and the nature of his/her research.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
