Answer:
1. probability
2. head represents cats (let's say) and tails represent dogs, flip two coins to determine whether the family has 2 cats or 2 dogs or 1 cat and 1 dog.
3. Take two coins, flip them, record heads and tails of each flip for 50 flips (I ain't no doing this)
4 - 6. answer these questions based on the data you got...
The End
To solve this you can make a proportion where the matching sides will correspond to each other. It should look something like this:
Now you must cross multiply
10*42 = 15*x
420= 15x
To isolate x divide 15 to both sides
420/15 = 15x/15
28 = x

Answer:
D.
Step-by-step explanation:
In direct variations, we would have:
Where <em>k</em> is some constant.
Since this is indirect variation, instead of that, we would have:
To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>
<em /><em />
Now plug this back into the variation:
The answer is D.
