without replacement draws 1 and then another. (odds of drawing purple)
first draw 7/13
second draw 6/12
7/13•6/12 = 42/156 or 21/78 or 7/26
with replacement.
first draw 7/13
second draw 7/13
7/13•7/13 = 49/169

Step-by-step explanation:
Let's get our relevant base equations listed out:
d = 2r
area = pi*r²
c = πd
Thus, d=2*5m = 10m, c=π*10m=10π m, and area = 25m²*π

Answer:
x=26
Step-by-step explanation:
All straight lines have a degree of 180, so both equations should equal 180.
4x + 4 + 4x - 32= 180
8x + -28 = 180
8x = 208
x = 26
