It is normal based on the Central Limit Theorem. According to the theorem, an appropriately big sample (infinite) size from a population with a limited level of variance, the average of all samples from the same populace will be roughly equivalent to the mean of the population.

EF = 50 in.
In similar figures, corresponding sides are proportional.  We use the similarity statement ABCD~EFGH to write a proportion:

Cross multiply the proportion:
45*x = 75*30
45x = 2250
Divide both sides by 45:
45x/45 = 2250/45
x = 50
 
        
        
        
Answer:
   19 m
Step-by-step explanation:
The width is 2 less than the length, so the perimeter is ...
   P = 2(L +W)
   72 = 2(L +(L -2))
   76 = 4L . . . . . . . . add 4
   19 = L
The length of the rectangle is 19 meters.
 
        
             
        
        
        
Okay, we know that the expenses for the day is 210.
Knowing this, and the price of the taco, we write the inequality:
3.25t > 210
t = number of tacos
Now divide both sides by 3.25:
t > 64.62 (rounded)
Because a taco stand can't sell a fraction of a taco, we know that the taco stand has to sell more than 65 tacos for a profit.
