All plots correctly show the range, 5–73.
The 1st, 2nd, and 4th choices correctly show the median, 54.
Of those, the 2nd and 4th choices correctly show the first quartile, 14.
Of those, only the 2nd choice correctly shows the third quartile, 61.
_____
There are an odd number of data points, so the middle one is the median. That value divides the remaining points in to two groups of 5. That number is also odd, so its median is the middle of that group. If we use x for the lower half and y for the upper half, you have
... (5 x 14 x x) 54 (y y 61 y 73)

Answer:
25/2
Step-by-step explanation:
Caio comprou uma lembrança para todos os amigos e gastou R $ 12,50.
Comparando e resolvendo as opções dadas a nós,
a) 125/2 = 62,5
A opção a está errada
b) 25/5 = 5
Opção b está errada
c) 125/5 = 25
A opção c está errada
d) 25/2 = 12,50
A opção d está correta
Portanto, a fração que pode representar este valor é 25/2
Answer:
z = 8
Step-by-step explanation:
All angles inside a triangle add up to 180 so:
90 + 40 + 5z + 10 = 180
5z + 140 = 180
5z = 40
z = 8
x - y = 35
x = 6y
Plug 6y in for x in the first equation.
6y - y = 35
5y = 35
Divide both sides by 5
y = 7
x = 6y
x = 6(7) = 42
42 and 7
Letter C
Since we had the answers we could have just tried the answers but you will not always have multiple choice so this is the method for solving.
