The experiment described is an example of matched pairs because it is going to compare the reaction of drivers at two different volume levels.
<h3>What is the matched pairs type of experiment about?
</h3>
Matched pairs are a type of experiment that puts one or more individuals in two different situations to compare the results and draw a conclusion regarding this reaction.
According to the above, the situation described is an example of matched pairs because it requires the driver to respond to obstacles by listening to music at two different volume levels and in this respect their results are compared to establish whether the volume affects their performance reaction speed.

Answer:
The number of years it will take for them to be the same height is 6 years
Step-by-step explanation:
Here we have a question relating to optimization
Let the number of years at which they will be the same height be M
we then have
2 ft + (25/12 × M) ft= 10 ft + (9/12 × M) ft which gives
→ (25/12 × M) ft - (9/12 × M) ft = 10 ft - 2 ft
→ (25/12 × M) ft - (9/12 × M) ft = 8 ft
→4/3 M ft = 8 ft
Therefore, M = (8 ft)÷(4/3 ft) = 6
Therefore, it will take 6 years for them to be the same height.

Answer: 879
Step-by-step explanation:
The order of operations calls for Parenthesis, Multiply, Divide, Add, Subtract. From left to right.
So we do the parenthesis first (102 - 4)
-3 + 9 (98)
Next we multiply 9 and 98
-3 + 882
Lastly we add -3 and 882
