Answer:
17.5
Step-by-step explanation:
According to the study 70% of the internet searches used Google as search engine.
Thus if the event X is the proportion of the searches using Google engine, then expected value of the event X, E(X) = 0.7
From here we can find the expected number of internet searches of a sample of 25 people by multiplying 25 and 0.7, i.e 25*0.7=17.5
SA = 2LW + 2LH + 2WH
Since it is a cube, all of the dimensions, LWH, will be the same.
SA = 2s^2 + 2s^2 + 2s^2
SA = 6s^2486 = 6s^2
Divide both sides by 681 = s^2Take the square root of both sides. 9 = s
Hope this helped☺☺
X=14, is the answer I believe. Good luck!
