The total cost for a production process is equal to $1,000 plus two times the number of units produced. The mean and variance fo

Andrej [43]

Answer:

$\mu_p=2000\\\\\sigma_p^2=3600$

Step-by-step explanation:

Let X be the number of units produced, and P be the cost of production.

#Given that $\mu_x=500, \sigma_x^2=900$

Cost of production can be calculated as:

$P=1000+2X$

#Mean of the total cost is calculated as;

$\mu_p=1000+2\mu_x\\\\=1000+2(500)\\\\=2000$

Hence, the mean cost of production is $2,000

#Variance of the total cost is calculated as;

$\sigma_p^2=2^2\sigma_x^2\\\\=2^\times 900\\\\=3600$

Hence, the variancecost of production is $3,600

You may remember that the area of a triangle is A=12B⋅H, where B is the base of the triangle and H is the height.

Alexxandr [17]

Answer:

b = 6

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh

9 = 1/2 *(2h) * h

9 = h^2

Take the square root of each side

3 =h

The base is 2h

b = 2(3)

b = 6
