The following measurements (in picocuries per liter) were recorded by a set of carbon monoxide detectors installed in a laboratory facility: 238.6,168.3,192.4,237.6,204.2,155.3 ,233 using these measurements, construct a 99% confidence interval for the mean level of carbon monoxide present in the facility. assume the population is approximately normal.

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).
