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)

Step-by-step explanation:
Answer:
a) 720
b) 60$
Step-by-step explanation:
a) each person is served 3 pancakes and there are 240 people, 240 x 3 = 720.
b) Each bag of mix costs 10$ and can make 120 pancakes, but we need 720 pancakes, which means six bags of mix (since 120x6 = 720). Since each cost 10$, 10 x 6 = 60$
Answer:
34091 dollars per person
Step-by-step explanation:
In order to answer the question, you have to divide the amount of debt by the amount of population to obtain the amount of dollars per person.
The debt was $10.5 trillion. A trillion is a thousand billion (1000 multiplied by a billion which is 
in scientific notation)
1000=
One trillion is 
The debt is: $ 10.5 x 
The population is scientific notation is: 308.0 x 
Dividing the amount of debt by the amount of population:
Simplifying and expressing it in standard notation:
34090.9 dollars per person
Rounding to the nearest dollar:
34091 dollars per person.
Answer:
g(f(- 2)) = 91
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x), that is
f(- 2) = - 2 + 7 = 5 , then
g(5) = 4(5)² - 9 = 4(25) - 9 = 100 - 9 = 91
