What is the value of c? ______ units
2 answers:
Answer:
The value of c is 5 units.
Step-by-step explanation:
Now by using the pythagorean theorem
Hypotenuse² = Perpendicular² + Base²
As in Δ WYZ.
WZ² = ZY² + WY²
Hypotenuse = WZ = c
Perpendicular = WY = 4 units
Base = ZY = 3 units
Put in the above
c² = 4² + 3²
c² = 16 + 9
c² = 25
c = 5 units
Therefore the value of c is 5 units.

Answer: 339/8788= 0.039
Step-by-step explanation:
Let black card be represented with B and the red card be represented with r. Therefore, P(B,r) is the expected value.
Hence, we say, (b,r) is not equal to (0,0) for the first state, we then, have a probability of B/r+B(the probability of drawing out a black card and loosing a point.
Also, (B-1,r) state with the probability of r/r+B(which is the probability of drawing out a red card and gaining a point).
The expected value is therefore;
B/r+B(-1+(B-1,r) + r/r+B(1+P(B,r-1))
Therefore, if we have negative, then;
P(B,r)=0,B/r+B(-1,r)) + r/r+B(1+P(B,r-1))...
P(0,0)=0; P(26,26) = 339/8788
=.039
Note: we say that the expectation at the start if we draw red,gaining +1 and if we draw black and then draw two reds you end +1. That is; 1/26 × 2/26 × 1/26 = 1+ 338/8788
= 339/8788.
