Do women wait longer than men to receive their orders at coffee shops? This question was studied by an economics major at Middlebury College. Which variable(s) in the data set are measured using a nominal scale? Age Group and Appearance Gender, Order, Age Group, and Appearance Gender and Order None of the variables Which variable(s) in the data set are measured using a ordinal scale? Gender and Order Gender, Order, Age Group, and Appearance None of the variables Age Group and Appearance Which variable(s) in the data set are measured using a ratio scale? None of the variables Wait Time Wait Time and Age Group Wait Time, Age Group, and Appearance

um i wouldnt really know try asking it while copying and pasteing

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
