Answer:
Explanation below
Step-by-step explanation:
First, it seems you are trying to get the 95% confidence interval (not just interval) for the predicted rate of Childhood Asthma in the city.
This city's particulate is 13 ppm.
The answer is "not reasonable".
Why?
This is because no data is given on the children in the city. 13 ppm is the value for the city's particulate; it is not the mean value for the predicted rate of childhood asthma in the city. If this mean value were available, the 95% confidence interval would be created around this mean.
Answer:
Step-by-step explanation:
You can simplify this by collecting the like terms. The only like terms are the pair 2x and 18 x
2x-18x = -16x
Now, put them back together,
-16x + 14y-19
Since y=2x+1 does not pass through the origin (i.e. there exists the constant term of 1 ), the variables y and x are not directly proportional - though, they do have a linear relationship.
-3 1/2 because if you do 2.8 times 1 and 1/4 you get 3.5 and 3.5 as a fraction is 3 1/2
Answer:
13.3 ft
Step-by-step explanation:
24² - 20² = d²
d = √(576 - 400) = √176 = 13.26649... ≈ 13.3 ft.
