Answer:
I solved it and my answer is number 1
Plot the graph then you do the vertical line test. You draw a vertical line on the graph. If the line touches the graph at just one point,note just one point then it is a function
Answer:
Test is Left tailed test
Parameter tested is standard deviation
Step-by-step explanation:
We are given the hypothesis as;
Null hypothesis; H0: σ = 8.6
Alternative hypothesis; H1: σ < 8.6
Where;σ is a constant generally known in statistics as the standard deviation.
Now, it's the alternative hypothesis that will let us know whether this is left tailed, right tailed or two tailed.
Alternative hypothesis says σ < 8.6.
This means that the values of σ that satisfy this hypothesis are less than 8.6 and thus are on the left hand side of 8.6 on a number line. Thus, the shaded region in a normal distribution curve will be on the left.
Thus, it's a left tailed test
Answer:
The correct answer would be...
c. 8(x + 4)(x - 7)

Answer:
Step-by-step explanation:
Forma ordinaria
La ecuación de la parabola de manera ordinaria está dada por:
(1)
Donde:
- (h,k) es la coordenda del vértice, en nuestro caso (0,0) ya que está en el origen.
- (h,k+p) es la coordenda del foco, en nuestro caso (0,1).
Por lo tanto h = 0, k = 0 y p = 1.
Remplazando estos valores en la ecuación de la parábola, tenemos:
(2)
Forma general
La forma general de una parábola esta dada por la siquiente ecuación
Reordenando la ecuación (2) tenemos:
