The names of all 135 students in a professor's class are written on identical slips of paper, and the slips are placed into a large glass jar. Then, the professor selects 5 random slips from the jar. Identify the kind of sample that is being used.

simple random sample.

Step-by-step explanation:

In the given scenario , the professor is using a lottery system which in term of statistics is known as simple random sampling technique.

In this technique a sample is drawn chosen from the entire population in such a way that all the participants in the population has an equal chance to get chosen.

Here , the professor selects 5 random slips from the jar and the chances of getting selected is equal for each students.

Thus , this is a simple random sample.

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).

answer: b.36 feet
