Answer:
D. 101
Step-by-step explanation:
(25x+1)+(25x-2)+(20x-1)+82=360
70x=360-1+2+1-82
70x=280
x=4
A=25x+1=101
The answer
by using fundamental definition
<span>The conditional probability of event B given event A is P(B|A)=P(A and B)/P(A) when two events are not independent.
so the only true answer is A, because </span>P(B|A)=P(A) if A and B are independents<span>

A. All remaining numbers are in Q because it goes "even" left, and "odd" right.
B. Probability of it not being in Q is 1/2
Answer:
c) HH E)AA
Step-by-step explanation:
Two right angles can be proved congruent by LA,LL,HA,HL properties.
HH and AA are not congruence property.
Two triangles can be proved similar by AA property. All congruent triangles are similar but all similar triangles are not similar.Hence right triangles can not be proved congruent by AA property.
Among the options given Option C and E are not congruence property.
For this case we propose a system of equations:
x: Variable that represents the amount of hours that Olivia's mother drove
y: Variable that represents the amount of hours that Olivia's father drove
So, we have:
From the first equation we have:
Substituting in the second equation:
Thus, Olivia's father drove 3 hours.
Olivia's mother drove 11 hours.
