Scale Drawings are drawings that are used to show the true size of something.
Scale drawings are most commonly used in maps, or in large scale drawings. These show the scale of something. It may show that 1cm is equivalent to 1km, which would allow someone to measure the map to see how far the distance it. It also allows a map to be made smaller, and less detailed- making it often easier to read.
Hope this helps :)

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

Math Help plwaseee eee

Answer:

14 in²; D.

Step-by-step explanation:

Hey!

To find the area of a trapezoid, we will add up both of the bases, divide by two, and then multiply the height.

In that case, we'll start by adding up 5 and 9.

5 + 9 = 14

$\frac{14}{2} = 7$ .

7 × 2 (height) = 14.

Thus, the area of the given trapezoid is $\boxed{14\:in^2}$ , or D.

Hope this helps!
