At a DBE lecture of 100 students there are 29 women and 23 men. Out of these students 4 are teachers and 24 are either men or teachers. Find the number of women teachers attending the lecture.

The number of women teachers attending the lecture is 1

Step-by-step explanation:

Let M denotes men , W denotes women and T denotes teachers.

Number of women = n(W)=29

Number of men = n(M)=23

Number of teachers=n(T)=4

We are given that 24 are either men or teachers.

So,n(M∪T)=24

We are supposed to find the number of women teachers attending the lecture.

n(M∪T)=n(M)+n(T)-n(M∩T)

24=23+4-n(M∩T)

n(M∩T)=3

So,No. of teachers those are men is 3

Total number of teachers = 4

So,  the number of women teachers attending the lecture= 4-3 = 1

Hence the number of women teachers attending the lecture is 1

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
