Answer:
how long this question is omggggggggg
Answer:
33. area of circle= pi X r^2 = (22/7)*r^2
7=(22/7)*r^2
49/22=r^2
7/root22=r
therefore, radius= 7/4.69 = 1.49
37. mean= (1+3+5+7+9)/6
mean=25/6 =4.2
38. mode=2.2
39. P(ball picked is blue)=3/(3+2+2)=3/7
40.P(e)+P(é)=1
0.03+P(é)=1
P(é)=1-0.03=0.97
