This means that you are in the experiment group
It is common to choose a group of people to study the effect of certain things like the one given in this question. The selection of people is done after designing the sample size for a certain population. The design varies depending on whether the analysis is qualitative or quantitative.
The people who lie in the sample size actually contribute to the experiment are said to be part of it.
Therefore, if you are part of the study that is used to test the effectiveness of a new drug for treating the common cold. It means you are part of the experiment group.

Answer:
30 mph
Step-by-step explanation:
let s represent speed and h represent rebound.
Given that s is proportional to h then the equation relating them is
s = kh ← k is the constant of proportion
To find k use the condition s = 20, h = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
s = 2h ← equation of proportionality
When h = 15 , then
s = 2 × 15 = 30 mph
Answer:
7y+12x=-16
y-step explanation:
Multiply everything by 7 to get rid of the fractions.
Distribute the 12 into (x-1)
Then subtract 28 from the 12
Finally add the 12x over
20% of 50....turn percent to decimal..." of " means multiply
0.20(50) = 10...so 10 is 20% of 50
If the number formed by two last digits of a number is divisible by 4, then a number is divisible by 4 as well.
