Answer:
5/12
Step-by-step explanation:
Given that,
Total no of cards = 12 with numbers 1 to 12
We need to find the probability of getting 5.
Probability = favourable outcomes/total no of outcomes
Favourable outcomes is 5 as it come one time
Total no of outcome = 12 (total no of cards)
So,
Hence, the probability of getting 5 is 5/12.

Answer:
13
Step-by-step explanation:
a pair=2
so 25/each pair of towns
25/2=12+1=13

There the same shape, same size so yes they are congruent
Answer:
- 12 ft parallel to the river
- 6 ft perpendicular to the river
Step-by-step explanation:
The least fence is used when half the total fence is parallel to the river. That is, the shape of the rectangle is twice as long as it is wide.
72 = W(2W)
36 = W²
6 = W . . . . . . the width perpendicular to the river
12 = 2W . . . . the length parallel to the river
_____
<em>Development of this relation</em>
Let T represent the total length of the fence for some area A. Then if x is the length along the river, the width is y=(T-x)/2, and the area is ...
A = xy = x(T -x)/2
Note that the equation for area is that of a parabola with zeros at x=0 and at x=T. That is, for some fence length T, the area will be a maximum at the vertex of this parabola. That vertex is located halfway between the zeros, at ...
x = (0 +T)/2 = T/2
The corresponding area width (y) is ...
y = (T -T/2)/2 = T/4
Equivalently, the fence length T will be a minimum for some area A when x=T/2 and y=T/4. This is the result we used above.
