Answer:
4.5
Step-by-step explanation:
Put numbers in order, 1,3,3,4,5,8,9,12
Divide by 2 because there are 2 numbers
Because 4.5 is in the middle of 4 and 5 that is your median
(d): y=2-4x
P(0;y) belongs to (d)
=> y=2-4*0
= 2
So P(0;2)
Q(x;0) belongs to (d)
=> 0=2-4*x
<=> x=1/2
So Q(1/2;0)

ANSWER:
5 10/13 rounded to the nearest tenth is A) 5.7.
___________________________
EXPLANATION:
Convert 5 10/13 to an improper fraction.
First, multiply the denominator by the whole number:
5 × 13 = 65
Next, add that to the numerator:
65 + 10 = 75
This is the new numerator. Place it over the old denominator.
5 10/13 = 75/13
-------------------------------------------------------
Now, convert the improper fraction to a decimal by dividing its numerator by its denominator:
75 ÷ 13 = 5.7692307692
This can be rounded to 5.7.
Answer:
48%
Step-by-step explanation:
We have 3 people and 5 floors
We can't have two or more people leaving in the same floor.
So, the first person to leave has 5 possibilities (all 5 floors)
Then, the second person will have only 4 possibilities, as this person can't leave in the same floor as the first one.
Lastly, the third person will have only 3 options (the 3 remaining floors that weren't selected).
The total number of possible choices, without restrictions, is 5 possibilities for each person, so 5*5*5 = 125 combinations
The combinations we want is 5*4*3 = 60 combinations
So the probability of all people choosing different floors is 60/125 = 0.48 = 48%
