Answer:
In a study of a weight loss program, 5 subjects lost an average of 50 lbs. It is found that there is about 28% chance of getting such results with a diet that has no effect.
Part A:
No, the program is not statistically significant because the results are likely to occur by chance.
Part B:
Yes, the program is practically significant because the amount of lost weight is large enough to be considered practically significant.
The easiest way to isolate the variable is to multiply by the reciprocal. This leaves n on the left and 12*(5/3) on the right.
The answer is 20
<span><span>A cargo plane flew to Moscow and back.
It took six hours longer to go there than it did to come back.
The average speed on the trip there was 152 mph.
The </span></span><span>average speed on the way back was 380 mph.
How many hours did the trip there take?
(x + 6)152 = 380x
228x = 912
x = 4
The trip there took 10 hours.</span>
