Answer:
-0.4=-(2/5)
-----------------------
0.4=0.1+0.1+0.1+0.1
=(1/10)+(1/10)+(1/10)+(1/10)
=(4/10)
=2/5
Therefore, -0.4=-(2/5)
-18 i dont really know but
Answer:
B and D
Step-by-step explanation:
Surveys are only tested with one group.
Either way. The probability of hitting the circle is:
P(C)=Area of circle divided by area of square
P(W)=(area of square minus area of circle divided by area of square
P(C)=(πr^2)/s^2
P(W)=(s^2-πr^2)/s^2
...
Okay with know dimensions, r=1 (because r=d/2 and d=2 so r=1), s=11 we have:
P(inside circle)=π/121 (≈0.0259 or 2.6%)
P(outside circel)=(121-π)/121 (≈0.9744 or 97.4%)
