Answer:
$0.059
Step-by-step explanation:
To find the unit price per sticker, divide the price by the amount of stickers.
$2/34 = $0.059
4x + 6 = -10<span>Simplifying
4x + 6 = -10
Reorder the terms:
6 + 4x = -10
Solving
6 + 4x = -10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 4x = -10 + -6
Combine like terms: 6 + -6 = 0
0 + 4x = -10 + -6
4x = -10 + -6
Combine like terms: -10 + -6 = -16
4x = -16
Divide each side by '4'.
x = -4
Simplifying
x = -4</span>
Answer:

Step-by-step explanation:
The given parabola has its focus at (-5,-5) and the directrix is at: y=7.
The equation of such parabola is given by the formula:

The vertex of the parabola is the midpoint of (-5,-5) and (-5,7).

The value of p is the distance from the (-5,-5) to (-5,1).
p=|1--5|=6
We substitute the values of the vertex and p into the equation to get;


Or

a. The marginal densities

and

b. This can be obtained by integrating the joint density over [0.25, 1] x [0.5, 1]:
