1522 customers at a major retailer were surveyed whether or not they made a purchase and were satisfied with the service they received. the table below organizes the responses. satisfied with service not satisfied with service total made a purchase 130 494 624 did not make a purchase 715 183 898 total 845 677 1522 a. [2 pts] what is the probability that a shopper selected at random made a purchase, given that they were not satisfied with the service? write your answer as a fraction.

yes. we do proportions in probabilities.

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

b
