A sample of 100 people is classified by gender (male/female) and by whether they are registered voters. The sample consists of 8
Alex_Xolod [135]

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

What is 0.26 repeating (.26 reappearing) as a fraction in simplest form?
IRISSAK [1]
 <span>Is it 0.262626...? 
repeating decimals you have to write at least two of the repeats so it is obvious what is repeating. 

1000x = 262.62626... 
10x = 2.62626... 
1000x - 10x = 260 
990x = 260 
x = 26/99</span>
