ccording to the Center for Disease Control, the prevalence of smoking among adults in Oregon is 16.3%. It is 20.5% in Louisiana.
1 answer:
Answer:
SE = 0.01730335
Step-by-step explanation:
We have two independent population (smokers in Oregon and Smokers in Louisiana).
Proportion of smokers (adult) in Oregon (Po) = 0.163
Proportion of non-smokers (adult) in Oregon (1- Po) = 0.837
Proportion of smokers (adult) in Louisiana (Ps) = 0.205
Proportion of non-smokers (adult) in Louisiana (1- Ps) = 0.795
With equal sample sizes (n) selected ==> no and ns = 1000.
Where no represents the sample size taken in Oregon and ns represents the sample size taken in Louisiana.
By Standard Error (SE) = ; the <em>n </em>implies equal sample size.
Therefore;
SE = = 0.01730335

Option b is true to match the vector field f with the given plot f(x, y)=x, -y
<h3>What is meant by a function?</h3>The earliest known attempts at the concept of functions can be traced back to the work of the Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. Originally, functions were idealized dependencies of one variable on another. For example, planetary positions are functions of time. Historically, this concept was developed in calculus towards the end of his 17th century, and the functions studied were differentiable (i.e. they had a high degree of regularity) until his 19th century ).
Given,
f(x, y) = x, -y
gt; at x⇒∞, y⇒-∞ downwards
at x⇒∞, y⇒+∞ downwards
Therefore, option b is true to match the vector field f with the given plot
f(x, y)=x, -y

Answer:
1 months
Step-by-step explanation:
Given
Anaconda
monthly
Python:
monthly
Required
Determine when their length will be equal
First, we need to write equations that determines the growth of each snake in m months.
For both snakes;
For the Anaconda, the expression is:
--- (1)
For the Python, the expression is
---- (2)
Both snakes will have equal length when both expressions (1 & 2) are equal
