Answer:
Al final, Eduardo tenía 20 dulces.
Step-by-step explanation:
Dado que al principio Eduardo y Adrián tenían el mismo número de dulces, y Eduardo le dio a Adrián la mitad de los dulces que tenía, y después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces, para determinar cuántos dulces tenía Eduardo al final se debe realizar el siguiente cálculo:
Eduardo 1X = Adrián 1X
Eduardo 0.5X = Adrián 1.5X
Eduardo 1.25X = Adrián 0.75X
0.75 X = 12
X = 12 / 0.75
X = 16
1.25 X = 16 x 1.25 = 20
Así, al final, Eduardo tenía 20 dulces.

Answer:
30 degrees
Step-by-step explanation:
There are 12 seats. There are also 360 degrees in a circle.
If each seat is evenly spaced from another, there are 12 identical angles that are all spaced next to each other and sum up to 360 degrees.
360 degrees divided among 12 identical angles is 360/12 = 30 degrees
Answer:
1. How many hours do you spend on studying on Saturday?
2.How many hours do you spend on playing game on Saturday?
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
Statistical questions means that when you ask, you expect to have the variety of answers. Because each person will give different answer.
Two statistical questions that Evan could have asked to get his results are;
1. How many hours do you spend on studying on Saturday?
2.How many hours do you spend on playing game on Saturday?
Evan could not have asked a non-statistical question to get his results because there is only on answer and you expect the same answer from everyone you ask.
For ex: how many students spend 3 hours studying, the answer is only one, it is 2 in Evan survey.
It is 4 because you have to add it then multiply
