You could  list the possibilities:
(1,2) (1,3( (1,4) (1,5) (1 , 6) , 2,3) etc

then required probability =  the count of these possibilities /   36

36 is the total  number of possible outcomes

The manufacturer of computers spends $500 to make each computer and sells them for 800. The manufacturer also has fixed costs ea
ryzh [129]

Answer:

C(x) = 5700 + 500x

Step-by-step explanation:

Total cost = fixed cost + variable cost

Fixed cost are cost that do not change in the process of production such as machineries, furnitures & fittings.

Variable cost are cost that changes with production such as cost of raw material, cost of labor.

From the question:

Fixed cost= $5,700

Cost per unit of computer = $500

If x number of computers are produced in a month

Variable cost = 500x

Total cost = fixed cost + variable cost

C(x) = 5700 + 500x

Where,

C(x) = total cost

5700= fixed cost

500x= variable cost

Which of the following statements are true about the equation below?
max2010maxim [7]
Given: x^2 - 6x + 2


Statements:

1) The graph of the quadratic equation has a minimum value:TRUE. WHEN THE COEFFICIENT OF X^2 IS POSITIVE THE PARABOLA OPEN UPWARDS AND ITS VERTEX IS THE MINIMUM.

2) The extreme value is at the point (3 , - 7): TRUE

You have to find the vertex of the parabola:

x^2- 6x + 2 = (x - 3)^2 - 9 + 2 = (x - 3)^2 - 7 => vertex = (3, -7)

3) The extreme value is at the point (7, -3): FALSE. THE RIGHT VALUE WAS FOUND IN THE PREVIOUS POINT.

4) The solutions are x = - 3 +/- √7. FALSE.

Solve the equation:

(x - 3)^2 - 7 = 0 => (x - 3)^2 = 7 => (x - 3) = +/- √7 => x = 3 +/- √7

5) The solutions are x = 3 +/- √7. TRUE (SEE THE SOLUTION ABOVE).

6) The graph of the quadratic equation has a maximum value: FALSE (SEE THE FIRST STATEMENT).

99 POINTS HURRY PLS!! Kathy lives directly east of the park. The football field is directly south of the park. The library
KATRIN_1 [288]
You have a larger right triangle (vertices: football field, park, home) with an altitude drawn to the hypotenuse. The altitude creates two more triangles. The two new triangles are also right triangles, and all three triangles are similar.
Part a.

Let x = distance from park to library

9/x = x/12
x^2 = 9 * 12
x^2 = 108
x = sqrt(108)
x = sqrt(36 * 3)
x = 6sqrt(3)
Answer to part a. 6sqrt(3)

Part b.
Once you know x, use the value of x and 12 as the lengths of legs, and you are looking for the distance from the park to the football field which is the hypotenuse.

Let y = the length of the hypotenuse which is the distance from the park to the football field.


(6sqrt(3))^2 + 12^2 = y^2
108 + 144 = y^2
y^2 = 252
y = sqrt(252)
y = sqrt(4 * 9 * 7)
y = 6sqrt(7)
Answer to part b: 6sqrt(7)
