Answer:
O is largest, C is medium, and T is smallest
Step-by-step explanation:
You need to pay close attention to the side length. The higher the length, the smaller the angle.

So 1 head per squirel and 1 head per bird
4 legs per squirel and 2 legs per bird
s=number of squirels
b=birds
the equatinos should be
1b+1s=number of heads=16
and
2b+4s=number of legs=44
(note 2b=2 times b)
so we aolve
b+s=16 and 2b+4s=44
simplify the second equaiton by divideinb by 2
2b+4s=44
divide 2
b+2s=22
b+s=16
and
b+2s=22
we can actually add the two equations together with the first one made negative
-b-s=-16
<u>b+2s=22+</u>
0b+1s=6
s=6
subsitute
b+s=16
b+6=16
subtract 6 from both sides
b=10
10 birds
answer is c
Answer: WX = 4
Concept:
Here, we need to know the idea of segment addition postulate.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
<u>Given information</u>
VX = 18
VW = 14
<u>Given expression deducted from the segment addition postulate</u>
WX = VX - VW
<u>Substitute values into the expression</u>
WX = 18 - 14
<u>Simplify by subtraction</u>
WX = 4
Hope this helps!! :)

Answer:
X = 0.5*(p1+p2)*n
a) X = pn
Step-by-step explanation:
Hello!
Since the coin is randomly chosen we can give the probability of choosing one or the other 0.5.
Now, X must be given by the probability of heads for either of the coins, since we do not know which coin have been choosed we must consider both of them, but multiplied by the 0.5 probability to choose one of them.
That is:
X = 0.5*(p1+p2)*n
a) If p1 = p2 = p
X = p*n
which makes sense since is the same as only having one coin
