A study of the effectiveness of a flu vaccine was conducted with a sample of 500 people. The results of the study are given below. If a person is selected at random from the sample, find the specified probabilities, recording your answers as a %. The person has two injections ___

The person did not get the flu ___

The person got the flu and had one injection ___

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
