A detergent company is trying to find a new stain remover ingredient to put in its detergent Company managers know that baking

soda or bleach will be used. They also know that water temperature, cold and warm, affects the stain removal process. An experiment

will compare all combinations of these choices. Four types of stains on the same fabric will be subjected to each treatment and scored

for stain removal quality. What is the experimental unit?

A. The fabric

B. The baking soda and bleach

C. The temperature of the water

D. The detergent

E. The stains

A. The Fabric

Step-by-step explanation:

By definition and experimental unit is the entity which is subjected to different types of treatments during the experiment.

Here the fabric has been stained with different types of stains and and then have been treated with baking soda and bleach under different temperature environments. In the experiment each time the fabric has been given different treatment than the previous one. That's why the fabric is experimental unit in the experiment mentioned in the question.

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: i feel you honey.
