A box is contructed out of two different types of metal. the metal for the top and bottom, which are both square, costs $5 per s
patriot [66]
Total cost, C = 8x^2 + 12xz 
volume, V = (x^2)*z = 10 
C = 8x^2 + 12x*10/x^2 
= 8x^2 + 120/x 
dC/dx = 16x - 120/x^2 = 0 
16x = 120/x^2 
x^3 = 120/16
 x = 1.957 ft

d^2C/dx^2 = 16 +240/x^3 = +ve for x = 1.957 
so, C is minimum when
x = 1.957 ft z = 2.61 ft

Length of the base x is 1.957 ft and height of side z is 2.61 ft

What is the value of x in the solution to the following system of equations?
dlinn [17]
The system of equations is
x - 2y = 2          (1)
3x + y = 6         (2)

From (1), obtain
x = 2y + 2        (3)

Substitute (3) into (2).
3(2y + 2) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
From (3), obtain
x = 2*0 + 2 = 2

Answer:  (2, 0)  or x=2, y=0

Kite K L M N is shown. The lengths of sides L M and M N are congruent. The lengths of L K and K N are congruent. Angle K is 99 d
Tresset [83]

Answer

\angle \ LMN=49\textdegree

Step-by-step explanation:

The diagonals of kite KLMN meet at 90°

Since, LK and KN are congruent,\angle KLM and\angle KNM form a set of opposite congruent angles. Congruent angles are equal.

All interior angles of a kite add up to 180°, therefore:-

\angle LMN=360\textdegree - 2\times106\textdegree-99\textdegree\\=49\textdegree

Alison has been hired to sell two different homes on the same street that two houses apart. She predicts that Home A has a 75% c
Karolina [17]

Using conditional probability, it is found that there is a 0.2857 = 28.57% probability that house A does not sell given that house B does not sell due to it's poor condition.

Conditional Probability

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem:

  • Event A: House B does not sell.
  • Event B: House A does not sell.

Home B has a 30% probability of selling, so a 100 - 30 = 70% probability of <u>not selling</u>, hence P(A) = 0.7.

20% probability that <u>none</u> sells, hence P(A \cap B) = 0.2.

Then, the conditional probability is:

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2}{0.7} = 0.2857

0.2857 = 28.57% probability that house A does not sell given that house B does not sell due to it's poor condition.
