Acertain one-day seminar consisted of a morning session and an afternoon session. if each of the 128 people attending the seminar attended at least one of the two sessions, how many of the people attended the morning session only? (1) 3/4 of the people attended both sessions(2) 7/8 of the people attended the afternoon session

16 people attended the morning session only

Step-by-step explanation:

Total number of people attending the seminar = 128

Let M represent those dat attended the morning session.

Let A represent those that attended the afternoon session.

We are told that 3/4 of the people attended both sessions.

3/4*128 = 96

96 people attended both sessions

We are also told that 7/8 people attended afternoon session.

7/8*128 = 112

112 people attended the afternoon session.

To find those that attended the morning session only, we will use a Venn diagram

x -96 + 96 + 16 = 128

x = 128 -16

x = 112

Those that attended the morning session only = x - 96

= 112 - 96

= 16

16 people attended the morning session only

the answer is 21%.

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
