The expression $15x+11$ represents the perimeter of the trapezoid. What is the length of the fourth side? A trapezoid. The shorter base is labeled 3 x plus 4. The legs are labeled 2 x plus 3 and 4 x minus 1. The length is .

Step-by-step explanation:

Given that:

Perimeter of the trapezoid =

Shorter base =

One leg =

Second base =

To find:

The length of fourth Side = ?

Solution:

Let us have a look at the perimeter of a trapezoid.

Perimeter = Sum of all the sides

Let the fourth side =

Using the formula and putting the given values:

Fourth side is:

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.

the answer is y = 11.54

hope this : )
