The distance depends on the time.
So now we need to find the constant of variation or the constant of proportionality.
To do so we must find y(the dependent variable) and x(the independent variable).
To find the constant(k) we must find y/x
Since y/x=k
Then 2.25/.75=k
k=3
<h2>
C. { HH, HT , TH, TT}</h2>
Step-by-step explanation:
Sample Space of any event E is the set of all possible outcomes whenever that event takes place.
Here, event E : Tossing 2 coins
Now, as we know, when an unbiased coin is tossed,
The total outcomes = {Head, Tail}
So, when two coins are flipped, the total outcomes are 2 x 2 = 4.
Sample space = { Head Head, Head Tail, Tail Head, Tail Tail}
or, S = { HH, HT , TH, TT}
For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park.
For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.
