The answer is d. wow I still hate geometry.
Answer:
Step-by-step explanation:
7e^x=343
/7 /7
e^x=49
By trial and error, x must be between 3 and 4, but closer to 4.
Further trial and error says x must be between 3.8 and 3.9, but closer to 3.9
Another trial and error says x must be between 3.89 and 3.9.
The closest answer I got was 3.891821
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:
0.13
Step-by-step explanation:
to change a percent to a decimal you just move the decimal 2 places to the left
