Answer:
Range is {y | y ≥ –11}
Step-by-step explanation:
This is quadratic equation.
<em>A quadratic equation's range can be found if we find the vertex.</em>
For quadratic equations that have a positive number in front of 
, it is upward opening and thus <u>all the numbers greater than or equal to the minimum value of vertex is the range.</u>
The formula for vertex of a parabola is:
Vertex = 
Where,
is the coefficient of 
is the coefficient of 
From our equation given, 
and 
Now, coordinate of vertex is 
coordinate of the vertex IS THE MINIMUM VALUE that we want. We get this by plugging in the value [ 
] into the equation. So we have:
Hence, the range would be all numbers greater than or equal to 
Third answer choice is the right one.
A line perpendicular to another will have the opposite sign and be flipped
ex: slope is 4/5 the other lines slope will be -5/4
(-2,-1) (2,-3)
slope formula
y2-y1/x2-x1
-3-(-1)
____
2-(-2)
-3+1
___
2+2
-2
___
0
the slope of the perpendicular line is 0/-2 which is just 0
25% or 1/4 in chance. 4 marbles and 16 other colours. 4/16=1/4=25%
Answer:105
Step-by-step explanation:
Answer: The value of test statistic is 0.696.
Step-by-step explanation:
Since we have given that
Similarly,
At 0.01 level of significance.
Hypothesis are :
So, the test statistic value would be
Hence, the value of test statistic is 0.696.
