If a coin is fliped 20 times and a head comes up 11 times, what is the relative frequency of a head coming up?

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

r and t.

both are 64 degrees.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

the answer, i believe is y-8=1(x+4)
