Step-by-step explanation:
based on the story told I expected completely different questions.
but for the actually asked question the whole thing about gaining our not gaining weight is competent irrelevant. ignore it.
so, all we need to do is looking at the row totals.
27.4% of the participants took 1 vitamin.
49.5% of the participants took more than 1 vitamin.
so, 49.5% + 27.4% = 76.9% of all participants are taking vitamins in some form.
therefore, the second answer option is correct.
The square root of 147 when rounded to the nearest tenth is about 12.1
1) The set of elements is,
10n where n € {.....,-3,-2,-1,1,2,3....}
Not sure if the 2nd question is complete.
60 min/1 hr
60 sec/1 min
3.4 x 60 = 204 min
204 x 60 = 12240 seconds
12240 seconds is your answer
hope this helps
