Solution = (1,-3)
Answer= one solution
Answer:
80
Step-by-step explanation:
Using this as a guide,
Number of Registered voters = 60
Number of non registered voters = 40
Total number of women in sample is 80
Total number of men in sample is 20
Thus, the expected frequencies for female registered voters
= (80/100)*60
= 48
Expected frequency for female non registered voters is
= (80/100)*40
= 32
Therefore, the total number of females for the expected frequencies is
48+32 = 80
