Answer:
This is an "Experiment" type of study
Step-by-step explanation:
Researchers use various methods or techniques to conduct research and draw conclusions from it. Some of these methods are given below
1. Experiment
2. Observational study
3. Anecdotal evidence
1. Experiment: In this type of study, researchers have control over their setup and they can give directions or apply any treatment on their subjects.
2. Observational study: In this type of study, researchers cannot give directions or apply any treatment on their subjects but rather they can only observe what is going on.
3. Anecdotal evidence: Also refers to experience and can be defined as personal experience based on something.
The study that we are given is clearly an example of "experiment" since half of the participants were to told walk 2 miles a day for 6 weeks. The researchers have control over their subjects in this case and they gave directions to their subjects to do this and that.
This could have been an observational study if researchers had selected 10 people who walked 2 miles a day for 6 weeks and 10 people who did not walk 2 miles a day for 6 weeks and simply measured their blood pressure and come to a conclusion. This way, it would have been a case of observational study.
4- you can represent the siblings by
j+(1+2j)+(j-3)=26
Combine like terms
4J-2=26
4j=28
J=7
5- she paid 5.50 for 5 pounds (then got .50 off)
Answer:
2(m+3)
opening brackets
using +2 to multiply everything in the bracket
2m+6
=2m +6
Answer:
x = 
Step-by-step explanation:
f(x)=4
fx=4
÷f on both sides
x=
Even- quadratic, constant, rational (inverse squared), absolute value
odd- linear, cubic, rational (inverse), cube root
neither- greatest integer, exponential, log, radical (square root)
i hope this helps sorry i couldn’t remember all of them
