Answer:
i. terms = 5xy(z)^2 , -3zy
coefficient = 5 and -3
ii. terms = 1 , X ,x^2
coefficient = 1 , 1
iv. terms = 3 , -pq , qr, -rp
coefficient = -1 ,1 , -1
v. terms = X/2 , y/2 , -xy
coefficient= 1/2 ,1/2 and -1

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)

Answer:
38 people have a membership.
Step-by-step explanation:
That's because the bottom row shows how many years they've had the membership.
And the y axis shows how many people or the frequency of people having the membership for that amount of years.
So its a bar graph that shows you how many of the members have had the membership for a set amount of years.
So all you have to do is add up each column,
0-2 years = 6 people
2-4 years = 8 people
4-6 years = 10 people
6-8 years = 8 people
8-10 years = 6 people
6 + 8 + 10 + 8 + 6 = 38
