Answer:
The vertex of this equation is (2, -7)
Step-by-step explanation:
In order to find the vertex of this equation we start with the base form of the vertex form.
y = a(x - h) + k
With this equation (h, k) is the vertex. You can see that 2 lines up with h and -7 lines up with k. This shows that (2, -7) is the vertex.
Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that
against the alternatives 
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis 
, then P value is
![P = 2[1- \phi(\left | Zc \right |)]](https://tex.z-dn.net/?f=P%20%3D%202%5B1-%20%5Cphi%28%5Cleft%20%7C%20Zc%20%5Cright%20%7C%29%5D%20)
(1)
a)significance level 
from 1 eq we get
Therefore 
FROM Z TABLE
B) significance level 
from 1st equation we get
Therefore 
FROM Z TABLE
C) significance level 
from 1 eq we get
Therefore 
FROM Z TABLE
Answer:
x^2 - 12x = -27
Step-by-step explanation:
Here, we want to isolate the constant for the polynomial
To do this, we start by setting the expression to zero
Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value
Mathematically, we have this as;
x^2 - 12x + 27 = 0
x^2 - 12x = -27
