Answer:
A and B
Step-by-step explanation:
Quadratic Equations: f(x) = a(bx - h)² + k
Quadratic equations always have a degree of 2. That means that we will always have an x² term. Of the 4 choices, only A and B offer a term of x², making them a quadratic.
SOLUTION
If the table represents an inverse variation, it means that y is inversely proportional to x, written as

Removing the proportionality sign and introducing a constant k, we have

In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have

So, if it's an inverse variation, the relationship would be

In the second column, x = -2 and y = 7.
Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation
We have

Since we got y = 7, the relationship is therefore an inverse variation.
The constant k = -14
The equation for the inverse variation is
Answer:
x=2 y=1
Step-by-step explanation:
Solve the equations by substituting y=6x-11 into -2x-3y=-7.
-2x-3(6x-11)=-7
-2x-18x+33=-7
-20x+33=-7
-20x=-7-33
-20x=-40
x=2
To find y, substitute this value into the equation and solve for y.
y=6(2)-11
y=12-11
y=1
Answer:
Step-by-step explanation:
To find median and mode for
a) In a uniform distribution median would be
(a+b)/2 and mode = any value
b) X is N
we know that in a normal bell shaped curve, mean = median = mode
Hence mode = median = 
c) Exponential with parameter lambda
Median = 
Mode =0
