Answer:
55
Step-by-step explanation:
u + xy, for u = 20, x = 5, and y = 7
u + xy = 20 + 5 * 7 = 20 + 35 = 55
Answer:
okay so to figure out a perfect square a number has to be outlined by itself. 8 is not. 4 is because 2 times itself is 4. 81 is because 9 time itself is 81. 44 is not. 49 is because 7 times itself is 49. 125 is not. 150 is not. 144 is because 12 times itself is 144.
(8•365)•35 is the correct answer because 8 hrs of sleep each day times 365 days in a year = 2920 hrs slept in one year. Now you must take 2920 and multiply it by the 35 years she has been alive to get 102,200 hrs of sleep.
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that
Now we replace P(Y) * P(X) for P(Y∩X)
Cancel out P(X)
So 
Like that
Now we replace P(X) * P(Y) for P(X∩Y)
Cancel out P(Y)
So 
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
