15 1/3 - 6 1/4 - 4 2/3 = <span>4.41666666667 hours</span>
If one is 5"x3", and the other having the same orientation is 3"x?, then
by similar figures,
5/3=3/x
cross multiply,
5x=3*3
x=9/5=1.8"
With the original figure, it is possible to validate the above answer.
Answer:
Step-by-step explanation:
Hello!
The study hypothesis was that playing videogames improves the reaction time on elderly individuals. If so, then the average reaction time on the elderly that played videogames is less than the average reaction time of elderly that do not play video games.
In the null hypothesis, the researchers usually state the known information or the possibility that the experiment has no effect, in this case, that playing video games doesn't modify the average reaction time in the elderly. If this hypothesis was rejected, this means that playing videogames increases significantly the reflexes in elderly individuals and reduces their reaction time.
I hope it helps!
