Answer:
0.8239 is the population proportion of participants that tried quitting smoking.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 142
Participants that tried quitting smoking = 117
Parameter:
- A parameter is a numerical value that describes a population.
Population proportion can be calculated as:
0.8239 is the population proportion of participants that tried quitting smoking.
The equation would be y = -3/2x + 1/2
Answer:
its A
Step-by-step explanation:
Answer: D. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation: When distinguishing between quantitative variables, they could be classed as either discreet or continuous. This difference between a discreet and continuous variable lies in whether the variable has a finite number of values or not. When a variable can only take up a certain number of values usually while numbers within a certain interval, then such varibak eis said to be finite. On the other hand variables which can take up any value within an interval are said to be continuous as they can take up an uncountable number of values within an interval. When weight is being recorded, it could take up an infinite number of values including decimal within an interval making it difficult to ascertain the number of possible values within the interval.
Here you'll need differential calculus.
The distance between (3,0) and (x, sqrt(2)*x + 4) is given by the distance formula:
distance: sqrt [ (3+x)^2 + (sqrt(2)*x + 4)^2 ]
Differentiate this, and then set the resulting derivative = to 0. Solve for x. Test your results to ensure that the distance d is actually the SMALLEST, given the root(s) x that you've found.
Write the coordinates of this point on the curve as ( x, f(x) ).
