Answer:
An experimental study
Step-by-step explanation:
An experiment deliberately imposes some treatment on individuals in order to observe their responses.
An experimental studies formulates some conditions in order to make an inference. An observational study tries to gather information without disturbing the scene they are observing.
This is then an experiment because people are deliberately asked to taste two muffins and asked for their response.
Answer:
3 Is the Radius
Step-by-step explanation:
Diameter is always 2R (R for radius), as they have given us the diameter of 6 we can conclude the answer by forming a simple equations
D=2R
6=2R
3=R
The speed of the plane will be 875km/h and the speed of the wind will be 125km/h.
<h3>How to calculate the speed?</h3>
It should be noted that the speed is calculated as:
= Distance/Time
Based on the information, the DC10 airplane travels 3000 km with a tailwind in 3 hr. It travels 3000 km with a headwind in 4 hr.
Therefore, (v + w) = 3000/3
v + w = 1000 .... I
(v - w) = 3000/4
v - w = 750 .... ii
We'll then add both equations together. Therefore, the speed of the plane will be 875km/h and the speed of the wind will be 125km/h.
