2 / 10 = 1/5
3/5 > 1/5
3 > 1
Hence, 3/5 is greater than 2/10
Answer:
6. What is the area of a circle you drew?
Step-by-step explanation:
Answer:
(6 - 6 - 9 - 3 - 2 + 2 + 4 +2 + 5 - 5) / 10
Step-by-step explanation:
The mean is adding up all the numbers then divide it by that many numbers. There are 10 numbers total.
Since some are negative you subtract those. basically 6 + (-2) is the same as 6 - 2.
6 - 6 - 9 - 3 - 2 + 2 + 4 +2 + 5 - 5
ow find that and divide by 10
Answer:
i believe it is -21, but i'm not sure
Step-by-step explanation:
just foil the two to get a quadratic expression
Answer:
a. 0.9
b. 0.024
c. 0.06
d. 0.2
e. 0.336
Step-by-step explanation:
Since A, B and C are mutually exclusive then P (A U B U C)=P(A)+P(B)+P(C) and P(A∩B∩C)=P(A)*P(B)*P(C).
a.
P (A U B U C)=P(A)+P(B)+P(C)
P (A U B U C)=0.2+0.3+0.4=0.9
b.
P(A∩B∩C)=P(A)*P(B)*P(C)
P(A∩B∩C)=0.2*0.3*0.4=0.024
c.
P(A∩B)=P(A)*P(B)
P(A∩B)=0.2*0.3=0.06
d.
P[(AUB)∩C]=P(AUB)*P(C)
P(AUB)=P(A)+P(B)=0.2+0.3=0.5
P[(AUB)∩C]=0.5*0.4=0.20
e.
P(A')=1-P(A)=1-0.2=0.8
P(B')=1-P(B)=1-0.3=0.7
P(C')=1-P(C)=1-0.4=0.6
P(A'∩B'∩ C')=P(A')*P(B')*P(C')
P(A'∩B'∩ C')=0.8*0.7*0.6=0.336
