Answer:
C. About 22
Step-by-step explanation:
13.3 + 2.8 + 5.6
= 21.7
Since 21.7 is close to about 22, we can conclude that C is the final answer.
Answer:
a 0
b) 0.9
c) 0.85
d) 0.25
e) 0.1
f) 0.0375
Step-by-step explanation:
a)
As A and B are two disjoints events, then P(A and B) is
P(A and B)=0
b)
As A and B are two disjoints events, then P(A or B) is
P(A or B)=P(A)+P(B)
P(A or B)=0.15+0.75=0.9
c)
P(not A)=1-P(A)
P(not A)=1-0.15=0.85
d)
P(not B)=1-P(B)
P(not B)=1-0.75=0.25
e)
P(not (A or B))=1-P(A or B)
P(not (A or B))=1-0.9=0.1
f)
P(A and (not B))=P(A)*P(not B)
P(A and (not B))=0.15*0.25=0.0375
Answer:
see explanation
Step-by-step explanation:
g(x) - f(x)
x - 3 - (3x + 2) ← distribute parenthesis by - 1
= x - 3 - 3x - 2 ← collect like terms
= - 2x - 5
There are no restrictions on the domain of - 2x - 5, thus
domain is all real numbers
80. Bc a 6:6 ratio is also a 1:1. So half of 160 them would be female.
