Answer:
370
Step-by-step explanation:
The venn diagram corresponds to students who were sick in January at a Chicago high school.
Students who had only fever= n(A) = 80
Students who had only headache= n(B) = 90
Students who had only cough = n(C) =60
Students who had both cough and fever = n(AC) = 10
n(AB) = 40:n(BC) = 30 n(ABC) = 20
Hence total students = 800
no of students who were absent due to other reasons = 100
REmaining students = 700
Students who were sick = sum of all =330
So no of students who were at school = 700-330 = 370
we are given with two equations: R=143-0.65a for women and R = 165-0.75a for men. In this prblem we are asked the age of a man when R is equal to 135. In this case, we use the second equation and substitute R with 135. In this case, 135 = 165 - 0.75 a; a is equal then to 40 yrs old. In 2, when x is equal to 4, then 0.5*4 + 3 is equal to 5.
