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>
All but the first statement are true.
_____
In the equation y=kx, "slope" is the coefficient of x, thus y=-3x.
Answer:
470
Step-by-step explanation:
every thing that is above 5 you go up one tenth.
Anything lower than five you keep the same tenth.
Exponents if those are the answer it bc the second number is an exponent

4^3=64
3^4=81
Answer:
1
Step-by-step explanation:
It has only 1 line, which is the line that passes through the midpoints of the upper and lower horizontal sides.
