RT equals RS plus ST
8x - 43 = 2x - 4 + 4x - 1
Simplify: 8x - 43 = 6x - 5
Bring variables to one side: 8x - 6x = -5 + 43
2x = 38
Divide both sides by 2:
x = 19
Calculate QS as twice RS:
QS = 2 * RS = 2 * (2x - 4) = 2 * (2*19 - 4) = 2 * 34 = 68
12 m^2/h to cm^2/min
12 m^2/h × 1 h/60 min = 0.2 m^2/min
0.2 m^2/min × 10000 cm^2/1 m^2 = 2000 cm^2/min
2000 cm^2/min
P(S) = Probability of Smash = 0.05 (5%)
P(M) = Probability of Modest = 0.5 (50%)
P(F) = Probability of Flop = 0.45 (45%)
Based on this, we utilize the model for discrete random variables, leading to:
E(X) = (0.05 * 5.2) + (0.5 * 0.9) + (0.45 * 0)
= 0.26 + 0.45 + 0
= 0.71 Mill'
Class B exhibits the most consistent sleep patterns since there's a smaller variance between 6.87 and 3.65 compared to the other classes.
Is the process like this: 38+29=67, then 67-23=44
50-44=6
thus possibly A?
