If A denotes some event, what does Ā denote?
If P(A) = 0.992, what is the value of P(Ā)?
Answer :
A denotes some event , Ā denotes the complement of A that is Ā contains all the events that does not occur in A.
Given: P(A) = 0.992
We know total probability =1
P(A) + P(Ā)= 1
P(Ā)= 1 - P(A)
P(Ā)= 1 - 0.992 = 0.008
P(Ā) = 0.008
Answer:
f(x) =4x² + x - 7
Step-by-step explanation:
f(x) = ax² + bx + c
f(1) = a + b + c
f(-3) = 9a - 3b + c
f(3) = 9a + 3b + c
a + b + c = -2 -----(1)
c = -2-a-b -----(2)
9a - 3b + c = 26 ------(3)
9a + 3b + c = 32 -------(4)
(2)->(3)
9a-3b-2-a-b = 26
8a-4b = 28
4(2a-b) = 28
2a-b = 7 ----(5)
(2)->(4)
9a+3b-2-a-b = 32
8a+2b = 34
2(4a+b) = 34
4a+b = 17 ----(6)
(5)+(6)
6a = 24
a = 4
sub a=4 into(6)
4(4)+b = 17
b = 1
sub a=4,b=1 into (2)
c = -2-4-1
c = -7
-2 4/6 ÷ -2/3=
-16/6 * -3/2=48/12= 4
Answer:
Step-by-step explanation:
hello :
ax+b =4x+9 so a=4 and b=9
Slope=(y2-y1)/(x2-x1)
=(5-4)/(4-2)
=1/2
slope > 0 => the line rises (from left to right).
