Step-by-step explanation:
A statistical question must have the characteristic of variability, that is, it must be a question that can be answered by a collective, where each person has a slaightly or big different answer, because all of them are different, that's the variability ingredient.
Among the options, you can notice that only B has this characteristic, it's the only statistical question. In other words, question A and C are questions about one person, they don't have variability.
Answer:
x=55
Step-by-step explanation:
Since the two lines are parallel the two angles are same side exterior. This means their sum is 180. So to solve put them equal to 180, x+9+2x+6=180.
First, combine like terms
3x+15=180
Then, subtract 15 from both sides
3x=165
Finally, divide the entire equation by 3
x=55
The formula to start with is (DC +CE) * CE = (AB + BE) * BE
Replace the letters with the numbers and equations:
(1 + x+4) * x+4 = (11 + x+1) * x+1
(x+5) * (x+4) = (x+12) * (x+1)
x^2 + 9x +20 = x^2 +13x +12
x^2 = x*x = 2x
11x+20 = 15x+12
20 = 4x+12
8 = 4x
x = 8/4
x = 2
