Respuesta:
- 0,60
Explicación paso a paso:
Dado que:
Media poblacional, μ = 683,5
Desviación estándar, σ = 52,1
Puntuación, x = 652,1
La puntuación estandarizada, Z = (x - μ) / σ
Puntuación Z = (652,1 - 683,5) / 52,1
Puntuación Z = - 31,4 / 52,1
Zscore = −0.602687
Puntaje estandarizado = - 0.60
No 12.14 is not bigger than 12.44
12.14 < 12.44
Answer:
x = 2.66666667
Step-by-step explanation:
3(x + 1) = 11
We multiply both x and 1 by 3 and get
3x + 3 = 11
Now we subtract 3 from both sides
3x + 3 - 3 = 11 - 3
3x = 8
Now divide both sides by 3
3x/3 = 8/3
x = 2.66666667

Answer:
1/5 hours i.e 0.2 hours (which is 12 mins)
Step-by-step explanation:
First note that 12 1/2 = 12.5, and 2 1/2 = 2.5.
To work out how many hours it takes hime to drive one mile, we divide the number of hours (2.5) by the number of miles (12.5),
i.e 2.5 ÷ 12.5
which equals 1/5 = 0.2 hours (= 12 mins).
One expression could be three x to the power of two. Let me know if that's right :)
