Answer:
5) c. 6 pi cm
6) A. 81 pi mm^2
Step-by-step explanation:
5) Circumference of a circle = pi d
d = 6 cm
so
C = 6 pi cm
Answer
c. 6 pi cm
6)
A = pi r^2
r = d/2 = 18/2 = 9
so
A = pi 9^2
A = 81 pi mm^2
Answer
A. 81 pi mm^2
Answer:
A. 0.42
B. 0.12
C. 0.45
Step-by-step explanation:
A. The probability that they make the right decision on the first try
First person = 60%
Second person = 70%
= 60% * 70%
= 0.42
B. Probability that they make wrong decision
= Wrong decision from first person * wrong decision from second person
Wrong decision = 1- right decision
= 1-0.60 * 1-0.70
= 0.40x0.30
= 0.12
3. Probability they delay decision
= 0.60(1-0.60)+0.70(1-0.70)
= 0.60x0.40 + 0.70x0.30
= 0.24+ 0.21
= 0.45
