Answer: 24.52%

-------------------------------------------

Work Shown:

Convert the time 7:45, which represents 7 min 45 sec, to seconds only
7:45 = (7 min) + (45 sec)
7:45 = (7*60 sec) + (45 sec)
7:45 = (420 sec) + (45 sec)
7:45 = (420+45) sec
7:45 = 465 sec

Do the same for 5:51
5:51 = (5 min) + (51 sec)
5:51 = (5*60 sec) + (51 sec)
5:51 = (300 sec) + (51 sec)
5:51 = (300+51) sec
5:51 = 351 sec

So the initial time is 465 seconds and it drops to 351 seconds
Subtract the values to find the amount dropped: 465-351 = 114

Divide that difference over the initial time: 114/465 = 0.24516

Move the decimal over 2 spots to the right to convert to a percentage: 0.24516 --> 24.516%

Then round to the nearest hundredth of a percent (2 decimal places) to go from 24.516% to 24.52% which is our final answer

So the reduction is roughly 24.52%
This means if you took 24.52% of the initial time and subtracted it off, then you'd get to about 351 seconds.

The 1990s and early 2000s could be considered the steroids era in a certain professional baseball​ league, as many players have
serg [7]

Answer:

Step-by-step explanation:

This could be an observational study because an experiment was not carried out by the research to further verify this hypothesis. Individuals are observed and data is collected from such observation. No effort is made by the researcher to affect the outcome of such results.

This study alone is not enough to conclude about a cause and effect relationship between steroids and the increase in home​ runs as thus study is not randomized and cant control other factors or links bringing about this result.
