Sammy is playing a board game. he rolls two number cubes, each numbered 1-6. if he rolls a sum of 3 he wins $60 dollars, otherwise he loses
$5 dollars. how much does sammy expect to win or lose on average per roll.

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

300pi

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

the radius is 2 times the diameter.
