Answer:
781250 
Step-by-step explanation:
Let y is the length of the farm field
Let x is the width of the farm field
Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:
2x + y = 2500 feet
<=> y = 2500 -2x
The are of the farm has the following formula:
A = x*y
<=> A = x(2500 - 2x)
<=> A = 2500x -2
To have the maximum area of field in square feet, we need to use differentials to estimate:
= 2500 - 4x
Set = 0, we have:
2500 - 4x = 0
<=> x = 625 feet.
=> y = 2500 - 2*625 = 1250 feet
So the maximum area of field is:
A = x*y = 625*1250 = 781250
Answer:
I belive the answer is D
Step-by-step explanation:
Answer:
0.2916, 0.1488, 0.0319
Step-by-step explanation:
Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.
Since each trial is independent there is a constant probability for any random car to need oil is 0.10
Let X be the number of cars that need oil
A) Here X is BIN(4,0.1)
B) Here X is Bin (8, 0.1)
C) Here X is Bin (20,5)
Answer:
3 + 5 + 7
Step-by-step explanation:
In addition it does not matter what order the numbers are in.
Answer:
well, 11 days
Step-by-step explanation:
if you were to put take out the y and put 2600 in the y place (2600=235x+15)
you solve that, and will come to 11 days
further explaining:
2600-15 = 2585
2585 / 235 = 11
( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)
but I think it is looking for substitution
Hope this helps!
