Answer:
1.67miles/hour
Step-by-step explanation:
Speed of the penguin = Distance/Time taken
Given
Distance = 1/3 mile
Time = 1/5 hour
Substitute the given data into the speed formula;
Speed = (1/3)/(1/5)
Speed = 1/3 * 5/1
Speed = 5/3
Speed = 1.67miles/hour
Hence the penguin speed in mi/hr is 1.67mi/hr
Answer: random sampling
Step-by-step explanation:
Because psychologists generally use college students as research participants, the research does not involve random sampling.
Random sampling is when each sample has an equal chance of being selected. Since the psychologists are targeting a particular set of students, the random sampling might not be applicable in this case.
You use Sin-Cos-Tan. Since Tan is opposite and adjacent (SOH-CAH-TOA) we use that equations which is listed below. We rearranged the equation to get O alone and then plug everything in.
