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
Exponential decay and range will be the set of natural numbers
<span>We define
day--------------------------X
hockey cards away ------------f(X)
</span><span>He gives 2 cards away ----------------on day 1----------f(X)=2 X=1
</span>He gives 4 cards away ----------------on day 2----------f(X)=4 X=2
He gives 8 cards away ----------------on day 3----------f(X)=8 X=3
the sequence of cards away 2,4,8,16,32,64,128,256,512,1024
f(x) = 2**(x)
The answers are
D <span>Each day corresponds to a unique amount of hockey cards in this sequence.</span>
And B <span>The graph of this sequence would pass the vertical line test.
Each element of the Domain (X = day), relates to a single value of f(x) = number of hockey cards
That is, every value of X must have only one corresponding value of f(x)
(One value of y, for each input X)
This can also be checked by using the vertical line test.
If we plot f(x) and we draw vertical lines in the curve, we can verify that at every input the line intersects only one point of f(x)</span>
Answer:
$136.50
Step-by-step explanation:
100 - 12 = 88% (How much percentage of money the student left)
88% = 120.12
1% = 120.12 ÷ 88 = 1.365
Before buying the book, the student had 100%
100% = 1.365 x 100 = 136.50
4/9 is the slope, I think
