C is the rigth answer because all the other three has two x values in common. :)
-10 is less than -5 because negative numbers are farther from 0. Same applies to -4 and -20.
A) 42x-12
6*7=42. 6*2=12
b) 21y
11+4+6=21
Answer:
Step-by-step explanation:
In a study of the relationship between pet ownership and physical activity in older adults, 586 subjects reported that they owned a pet, while 1931 reported that they did not. Give a 98% confidence interval for the proportion of older adults in this population who are pet owners. Lower limit Incorrect: Your answer is incorrect. Upper limit
p ± z × (1 - p/n)
z = 98%
p = 586/1931
= 0.3034697048
n = 1931
Approximately = 0.3035
Confidence interval =
0.3035 + 2.326 × ( 1 - 0.3035/ 1931)
