60 miles in 1 hour.
Distance is equivalent to the rate multiplied by time.
d = 60h
For example: the truck traveled for 4 hours. What is the distance?
using d = 60h
d = 60 miles * 4 hours
d = 240 miles.
X²+35=0
X(x+35)=0
X=0 x+35=0
-35 -35
X=-35
x=0, x=-35
Since there is no repetition allowed, there are 10 possibilities for the 1st digit, 9 for the 2nd, 8 for the 3rd, and 7 for the 4th. This gives a total of (10)(9)(8)(7) = 5040 four-digit codes.
For all odd digits to be used, there are 5 possibilities for the 1st digit (1,3,5,7,9), 4 for the 2nd, 3 for the 3rd, 2 for the 4th. This gives a total of (5)(4)(3)(2) = 120 codes that only use odd digits.
Therefore there are 5040 - 120 = 4920 codes that do not consist of all odd digits. The probability is 4920/5040 = 41/42.
