We know the perimeter formula would be 1200=2x+2y. And the area will be A=x*y
We can to take the derivative of the area formula to find where it is a max but we must first substitute something in from the first formula so we only have one variable.
1200-2x=2y
600-x=y
A=(x)*(600-x)
A=600x-x^2
Now we take the derivative:
A'=600-2x (set equal to 0 and solve)
0=600-2x
2x=600
x=300
Then when we plug this into the perimeter formula, we can solve for y
1200=2x+2y
1200=2(300)+2y
1200=600+2y
600=2y
y=300
So both the length and width are 300 yards, and the area would be 90,000 square yards
Hope this helps
I guess you are asking the measurement of the external angle of 60. If so it will be 120 or the supplement of 60 is 120
Answer:
0.6765 = 67.65%
Step-by-step explanation:
This situation can be treated as a binomial model with probability of success (dented can) of p = 0.05.
In 22 random trials, the probability of at least one success is determined by:

The probability that Karen has bought at least one dented can is 0.6765 or 67.65%.
