Determine whether the function rule models discrete or continuous data. function # 1: a movie store sells dvds for $15 each. the function c(d) = 15d relates the total cost of movies to the number purchased d. function # 2: a produce stand sells roasted peanuts for $2.99 per pound. the function c(p) = 2.99p relates the total cost of the peanuts to the number of pounds purchased p.

Function # 1: discrete data

Function # 2: continuous data

Step-by-step explanation:

Given :

Function 1: A movie store sells DVDs for $15 each

The function C(d) = 15d

d relates the  number of DVDs purchased

C(d) = total cost of DVDs

Function 2:A produce stand sells roasted peanuts  per pound for $2.99.

The function C(p) = 2.99p

C(p) = the total cost of the peanuts to the number of pounds purchased p.

Solution : Understand the fact that Discrete data is countable and Continuous data is measurable

So, we can see that in case of DVDs it is a countable case so FUNCTION 1 is discrete.

Its graphical representation is a bar graph

Again Understand the fact that Discrete data is countable and Continuous data is measurable

So, we can see that in case of peanuts it is a measurable case so FUNCTION 2 is continuous.

Its graphical representation is a histogram

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
