Answer:
0 =n
Step-by-step explanation:
2 − 10n = 2 + 4n
Add 10n to each side
2 − 10n+10n = 2 + 4n+ 10n
2 = 2 + 16n
Subtract 2 from each side
2-2 = 2+16n-2
0 = 16n
Divide each side by 16
0/16 = 16n/16
0 =n
Answer:
<u>x=−44/9</u>
Step-by-step explanation:
6/54−x=5/xx
Simplifies to:
−x+1/9=5
Let's solve your equation step-by-step.
−x+1/9=5
Step 1: Subtract 1/9 from both sides.
−x+1/9−1/9=5−1/9
−x=44/9
Step 2: Divide both sides by -1.
−x/−1=44/9/−1
x=−44/9
Answer:
Expected winnings for one spin = 0.1
Step-by-step explanation:
Expected Value = Sum of [(Probability of X)(Value of X)]
E(X) = Σ [P(X).X]
Two Events : X = +68 , P(X) = 1/38 and X = -2 , P(X) = 37/38
E(X) = [(68) (1/38)] + [(-2)(37/38)]
[(68)(0.03)] + [(-2)(0.97)]
= 2.04 - 1.94
= 0.1
123-67=56 points. So, subtract and you get 56 points in the second half
2 and 41/50 as a percent is 282%.
