Santos flipped a coin 300 times. the coin landed heads up 175 times. find the ratio of heads to total number of coin flips. express as a simplified ratio.

7:12 is the right answer.

Step-by-step explanation:

Number of times Santos flipped the coin = 300

Number of times the coin landed heads up = 175

We have to find the ratio of heads to total number of coin flips, this means 175:300.

Simplifying this we get,

Divide both the numbers by 5, we get 35:60

Again divide both the numbers by 5, we get 7:12

Now, this cannot be simplified further as it does not have a common factor. So, 7:12 is the right answer.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
