A. d = 55(t + 0.5)
Explanation:
distance = rate x time or d = rt
rate = 55 mph
time = t + 0.5
d = 55(t + 0.5)
Answer:
84
Step-by-step explanation:
56/2 = 28
28 x 3 = 84
To check work: 84/3 =28
A. 8.5. If you divide 55.25 feet by 6.5 feet, you get 8.5 miles.
Answer:
0.2752512
Step-by-step explanation:
The formula you are looking for is the binomial probability:
n!
P (X) = ------------ * (P)^X * (q)^n - X
(n- X)! X!
For your particular problem:
n=7
X=2
q = 1-p = .8
7!/(5!*2!)*(.2)^2*(.8)^5 = 0.2752512
Hope this helps, have a nice day/night! :D
