Answer:
0.38
Step-by-step explanation:
Let the even that a person has a dog be A. The probability is given 16% this implies:
<em>P(A)</em> = 0.16 ..... (1)
Let the event that a person has a cat denote by B. The probability of B is given to be 32% this implies....
<em>P(B</em>) = 0.32 ..... (2)
Then the event that a person has a dog and a cat will be denoted by A∩B. The probability of A∩B is given to be 10%: This implies:
<em>P(A∩B= = 0.12 .......(3)</em>
The event that someone owns a cat and a dog will denoted by the event <em>A∪B.</em> It is observed that A and B are not disjoint. This implies that the probability of this event is depicted as:
<em>P(A∪B) = P (A) + P(B) - P(A∩B)</em>
Substitute (1) , (2) and (3), in the above, we get:
<em>P(A∪B) = 0.16 + 0.32 - 0.10 = 0.38</em>
Answer:
A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).
Step-by-step explanation:
If Kristine spends $20 and saves the rest when she gets paid, the amount she saves should always be 20 less than the amount she earned.
The points (20, 0) and (25, 5) accurately represent this, where x is how much she earns and y is how much she saves.
(20, 0) represents her earning $20 and saving $0, because she spends $20 every time she gets paid.
(25, 5) represents her earning $25 and saving $5, because she spent $20.
So, the correct graph is A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).
First make the 62.4% as a decimal which is 0.624. Next you want to realize that the word "is" stands in place of an equal sign and the word "of" shows that you need to multiply. You can come up with the formula,
17.16 = 0.624x
and all you need to do is divide both sides by 0.624 and you get your answer.
x = 27.5
