hiro painted his room. after 3 hours of painting at a rate of 8 square meters per hour, he had 28 square meters left to paint.

let y represent the area (in square meters) left to paint after x hours.

complete the equation for the relationship between the area and number of hours.

A(t)=8t+52

Step-by-step explanation:

Step 1

A=8x3+28=52m²

Step 2

Find the linear equation

At=8t+52

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.

constants mean the stopped points or the points on a graph that nothing is changing, hope this
