Answer:
5x-13
The Answer is in the picture above please mark me brainliest. :)
B finished in second place because it is the second greatest number, and C finished in 5th because it is the 5th greatest number
P(x > 6.9) = 1 - P(x < 6.9) = 1 - P[z < (6.9 - 5.1)/0.9] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275.
Therefore P(x > 6) is about 2.5%
Answer: No, it’s rational number
