Answer:
Step-by-step explanation:
An event driven programs are process of programming by which an algorithm is written by programming on a UI element, placing an event listener such that it handled when triggered by calling a call-back function.
E.g is a click event on a button which is a UI element. An event listener example, mouse down can placed on it, and if a user mouse down on it, it is handled by calling a call-back function which might be to open a new page on website.
I am pretty sure that it is B
Let us assume as at when they meet, the time elapsed is x hours.
Fred 3 mi/h
John 2 mi/h
Distance = speed * time
Fred = 3x
John = 2x
Houses are 4miles apart.
So: 3x + 2x = 4 5x = 4
x = 4/5 hour = 0.8 hour or 0.8*60 = 48 minutes
Time elapsed is 0.8 hour or 48 minutes.
Given that <span>Henry divided the town into eight regions and randomly chose 10 households from each region in order to survey about traffic concerns. This type of sample is called</span> stratified sampling.
Stratified sampling<span> is a type of </span>sampling <span>method where</span><span> the researcher divides the population into separate groups, called strata and then, a probability </span>sample<span> (often a simple random </span>sample<span> ) is drawn from each group.</span>
<span>152.5 is 250% of 61
Hope this helps! (tried to do an explanation and my browser crashed...) </span>
