There are many conclusions we can come to for this!
70% of the flips were heads, and 30% are tails
28/40 was heads, and 12/40 were tails
There were more heads than tails
There were 14 more heads than tails

Answer:
11.4
Step-by-step explanation:
10:19
6 : X
Cross multiply, 10X = 114
Divide both sides by 10 to get X
Make sure to move decimal once and you get 11.4
The first statement "<span>y varies directly as x" means that as y increases, x also increases. To help us we need to assign a proportionality constant, k. We can now say:</span>
y=kx where k is just a constant. Then substitute the values,
180=kn
n=5k
With these equation we know that k is equal to (positive or negative) 6 and therefore we can get n to be (positive or negative) 30.
