In this situation, the order matters, since being 1st pick is not the same as being 2nd or 3rd. Therefore, there are 14 choices for the first pick, 13 remaining for the second pick, and 12 for the third pick. This is equivalent to the permutation 12P3.

(If order did not matter, this would use a combination.)
Using the Emperical rule:
68% lie with one one standard deviation:
16 + 1.7 , 16-1.7 = 17.7, 14.3
14.3 is part of the 68%.
The remaining 32% of the distribution is outside the range, with half being less than and half being greater than.
32/2 = 16
The probability of living loner than 14.3 Would be 16%
In order to do this you first have to solve the parenthesis. Why because the pemdas tells you so, first parenthesis then exponents then multiplication then division then addition and then subtraction. So first subtract 7 from 9 to get (2)^-3 now multiply 2 3 times. -2*-2*-2 to get -8

Answer:
12s.
Step-by-step explanation:
Given:
Hudson's velocity, Vh = 8.8 ft/s
Katie's velocity, Vk = 6.3 ft/s
Kate's head start distance, Dk = 30 ft
From the above, Katie and Hudson meet at th = tk = t
But, Dk = Dh + 30
Velocity = Distance/time
t × Vk = Dk
t × Vh = Dh
t × Vk + 30 = Dk
t × Vk + 30 = Vh × t
6.3t + 30 = 8.8t
t = 30/2.5
= 12 s
