Step-by-step explanation:

P(X≤6) equals 8C0(1/2)0(1/2)8 + 8C1(1/2)1(1/2)7 + 8C2(1/2)2(1/2)6 + 8C3(1/2)3(1/2)5 + 8C4(1/2)4(1/2)4 + 8C5(1/2)5(1/2)3 + 8C6(1/2)6(1/2)2 where nCs(p)s(1-p)(n-s) translates to n!÷s!÷(n-s)!×ps×(1-p)(n-s).

the answer is 48m^2!

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).
