An online streaming service providing television programs claims that a 30-minute program will stream with advertisements that average 45 seconds. A consumer advocacy group is investigating to
see if this claim is true. They recorded the times of 21 randomly selected advertisements. The times
are listed below:
Time
(seconds) 45 45 43 50 50
43 50 45 49 46 48 42 46 44 52 48 45 46 50 48
The mean and standard deviation for these times are 46.67 seconds and 2.78 seconds respectively.
Do these data provide convincing evidence that the true mean advertisement length is longer than
45 seconds?

check the picture below.

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).
