Jorge bought 16 apples for $8.00. let x represent the number of apples purchased, and let y represent the total cost. graph the line that represents the proportional relationship. (it doesn't have a graph because i need to graph it)

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In this problem

Jorge bought apples for

This is a direct variation problem

Let

x-----> the number of apples purchased

y-----> the total cost

The value of k is equal to the value of the slope m

Substitute

The linear equation is

using a graphing tool

see the attached figure

The answer in the attached figure

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
