bazaltina [42]
Answer:
Minimum:4 Quartile 1:15.5 Quartile 2:21 Quartile 3:26 Maximum:33
Step-by-step explanation:
Order out the numbers least to greatest then find the middle number, the middle number is the median or quartile 2, then you find the middle of the first half, that number would be the 1st quartile, then find the number in the middle of the second half, that is your 3rd quartile, the min is the smallest number max is the largest.
Answer:
18 percent
divide 9 by 20 and you get 0.18, then move the decimal over to the right two times and you will get 18
Substituting into the second expression,
Let x = Pacific Paradise
You can set up the equation like this:
x + (3x - 25) + (x + 18) = 928
(Combine like-terms)
5x - 7 = 928
(Add 7 to both sides)
5x = 935
(divide by 5 to both sides)
x = 187 (# of deluxe staterooms Pacific Paradise)
Next to find the # of deluxe staterooms of the other cruise ships create two equations
Let y = Carribean Paradise
x + 18 = y
(plug in the value of x which is 187)
187 + 18 = y
(combine like-terms)
205 = y (# of deluxe staterooms Carribean Paradise)
Let z = Mediterranean Paradise
3x - 25 = z
(plug in the value of x which is 187)
3(187) - 25 = z
(follow PEMDAS to simplify and combine like-terms)
536 = z (# of deluxe staterooms Mediterranean Paradise)
Finally check your answer by adding up all of your answers to make sure it equals 928
536 + 205 + 187 = ? (928!)
