D is the answer you are lookin' 4
Answer:
a. 1/26 , 3.8462%
b. 2/3, 66.7%
c. 1/6, 16.67%
Step-by-step explanation:
a. There are 54 cards in a standard deck, and 4 of each card
b. There are 6 possible numbers, and 4 are less than five
1 mile = 1.6km.
so
100 miles x 1.6km = 160.
The number of km between two cities is 160km.
Let "a" and "b" represent the numbers of people on teams Alpha and Beta, respectively. The problem statement tells you
a = (1/4)b
b - 6 - 12 = a + 12
The first equation can be rewritten to give an expresion for b:
b = 4a
This can be substituted into the second equation to get
4a -18 = a +12
3a = 30
a = 10
There were originally 10 people on team Alpha.
