you just subtract.
Answer:

Step-by-step explanation:
Let X be the number of units produced, and P be the cost of production.
#Given that 
Cost of production can be calculated as:

#Mean of the total cost is calculated as;

Hence, the mean cost of production is $2,000
#Variance of the total cost is calculated as;

Hence, the variancecost of production is $3,600
Answer:
m = -1/11
Step-by-step explanation:
m = rise/run = (y2-y1)/(x2-x1)
450/5= 90 units
90/5= 18 units
All you need to do is divide the real dimensions by the scale dimensions, and turn that answer to units. Notice: It said 1 unit: 5 feet
The scale drawing was 90 to 18 units.
I hope this helps!

Let's use the quadratic formula

a = 1, b = 0, c = -18

This is now split into two equations:

and

Since

The answer is

which means there are 2 real number solutions to the problem: answer B.
